Wireless projector: Wireless Projectors For Home, School and Conference Rooms

Best Portable Wi-Fi Projectors for Indoor, Outdoor Use: Reviews – Rolling Stone

If you purchase an independently reviewed product or service through a link on our website, Rolling Stone may receive an affiliate commission.

With more and more media now accessible on streaming services and viewable from different devices, our homes are quickly turning into entertainment hubs. A big screen TV can only get so big, but if you’ve got a blank wall, a projector is an option to consider that can stretch your screen significantly.


Home projectors have come a long way in the last decade, making them a lot more viable for the average person. One of the biggest changes is the adoption of Wi-Fi connectivity, which allows projectors to operate independently for cord cutters.

If you’ve been curious about making the jump from a TV to a projector, or plan on hosting outdoor movie nights this summer, we’ve researched and tested the best Wi-Fi enabled projectors you can get right now.

What Are the Best WiFi Projectors?

There are many factors to consider when choosing the right Wi-Fi Projector for you; below are the most important ones, which we considered while we were researching this list.

Wireless Connectivity: Wi-Fi projectors’ key feature is the ability to access the internet (aka streaming services) without a media streamer. Some also allow you to send media to the projector from your phone or tablet.

Ports: If your home Wi-Fi network isn’t very strong, or you want to plug in A/V accessories like a game console, you’ll need to use a projector’s inputs, which are commonly called ports. The most important port is HDMI, which is the current universal standard for sending digital audio and video from one piece of gear to another. Every Wi-Fi projector in this guide had one or more HDMI ports.

Native Resolution: All of the projectors we’re recommending have a native resolution of 1080P, which means they’ll display a full HD image. Some projectors say they’re 1080P projectors because they can accept an HD signal before compressing it down to a lower resolution.

Portability: All of the projectors below are small enough to fit inside a backpack, or light enough to bring from room to room. We’ve chosen smaller projectors because they’re easier to transport in and out of your home.

Editor’s picks

Speakers: Some of our picks have a built-in speaker system, so you don’t need to connect them to an external pair or A/V receiver. Some of these speakers sound surprisingly good, but we still recommend plugging in a higher-end pair if you’re setting up a home theater system.

Brightness: A projector’s brightness will determine how well you’ll be able to see its picture when there’s other light in the room. This is especially important to consider if you plan on using a projector outside, where there’s more light pollution.

1. Epson EpiqVision Mini EF12

Epson’s EpiqVision Mini EF12 is not only our favorite Wi-Fi-enabled projector, it’s one of the best we’ve ever tested.

The cube-shaped projector runs AndroidTV, a version of Google’s mobile operating system that supports every major streaming app. The Mini EF12 comes with some of these apps pre-installed, but you can add more by accessing Google’s Play store. Smart projectors can be a little slow, but that wasn’t a problem with the Mini EF12. We could navigate from app to app, and stream HD or 4K video without any stops or stutters.

Epson partnered with Yamaha to build an impressive 2.0 stereo speaker system into the Mini EF12. It’s loud and sounds well-balanced, so if you don’t want to plug speakers into your projector, this is the one to get. This was especially impressive during frantic scenes (think car chase), when a lot of different things were happening at the same time. We could clearly hear everything that was going on without one element of a scene overpowering another.

The Mini EF12’s video system is just as impressive. The picture remained ultra sharp regardless of what we were watching, though higher-resolution videos (especially 4K) looked the best. The Mini EF12 supports HDR (high dynamic range), so colors on newer TV shows and movies really popped. The projector’s 1,000 lumen lighting system showed a pretty bright picture that only faded in a room filled with natural sunlight. If you plan on watching videos outdoors, this is a must-have feature.

The EpiqVision Mini EF12 has a pair of HDMI ports, which is plenty for a projector, plus a headphone jack for connecting speakers and a USB port for playing media off a flash drive. The USB port is a nice touch because it allows you to play videos when you’re totally offline.

If you’re looking for a Wi-Fi projector with virtually no compromises, Epson’s Epiqvision EF12 is the one to get.

Nebula Cosmos

Nebula has made some of our favorite projectors in the past, and the Cosmos is its best one yet. We’ve been testing the 1080P model, but there’s a 4K option and a portable version, which we’ll get into a little later.

The Cosmos shares a lot of the same great features as Epson’s EP Mini EF12. It runs Android, and was super responsive when we were picking apps and streaming high resolution footage. Its 2.0 speaker system wasn’t quite as good as the one in Epson’s projector, but it never distorted during loud action sequences, and was especially good at presenting dialogue clearly.

Its 900 Lumen lighting system held up well when light leaked through our blinds during the daytime, but we wouldn’t recommend trying to watch a movie outside in broad daylight. One of the features that impressed us the most about Nebula’s Cosmos was its color reproduction. Your experience will vary based on whether or not the videos you’re watching support HDR (high dynamic range), but they looked vivid in our tests.

Part of what makes the Nebula Cosmos great is its remote, which has a dedicated autofocus button. This may not sound like a big deal, but it makes operating the projector so much better. If its image gets a little blurry — this can happen if you accidentally bump the projector, or when it’s first turned on — you can make it look sharp without navigating into obscure settings. If you’re new to projectors, Nebula took a great deal of time making sure it’s as user friendly as possible.

We’re also fans of the Cosmos’ array of ports: Two USB ports (use one to play videos off a flash drive and the other to charge your phone), a headphone jack, and an optical audio output. You can use the optical audio output to plug the Cosmos into an A/V receiver instead of HDMI if your equipment is a little older.

As we mentioned earlier, this 1080P version of the Cosmos is one of three projectors in Nebula’s new lineup. If you crave ultra-portability, we recommend the Nebula Solar, which has a built-in battery that lasts up to three hours on a full charge. If you’re setting up a serious home theater, consider the Cosmos 4K, which has a brighter lighting system, and four built-in speakers.

You can’t go wrong with any of Nebula’s new projectors, but we feel the 1080P Cosmos hits the sweet spot.

Buy Nebula Cosmos $599.99

3. Vankyo V630W


Vankyo’s V630W is a budget-friendly Wi-Fi projector that will work well under optimal conditions.

It has a few limitations: a dimmer bulb, no speakers, fewer ports, no native smart features, but you can fix most these issues pretty easily. But plugging a media streamer into its HDMI port and speakers into its headphone jack, the experience of using the V630 becomes a lot more comparable to the more premium projectors above.

You can even avoid getting the media streamer by sending video to the projector over Wi-Fi directly using a feature called screen mirroring, or plugging a flash drive into its USB port. It may take a little more effort, but Vankyo’s projector can hold up under the right conditions.

One feature the V630W has that our other recommendations lack is a manual focus system. You can adjust the projector’s focus and screen size by turning dials on top of the projector, letting you make micro adjustments instead of relying on the competence of an auto-focus system.

If you understand its limitations, and don’t mind putting in a little bit of effort to work on them, Vankyo’s V630 is a very good Wi-Fi projector.


4. GPX Rechargeable Projector with Bluetooth

There’s a lot packed in to this little projector, especially for it affordable price tag compared to the others. Weighing just over 3.5 pounds, it’s entirely portable, while still providing more than enough ports, including 2 HDMIs, USB, AV, and microSD. Or for going entirely wire-free, it’s Bluetooth-ready as well. In our tests, this was extremely quick to set up right out of the box, literally just plug in and start it up. The rechargeable battery lasts a while when away from an AC plug (though that’s an option too), and the LED bulb inside can crank to 5000 lumens, and last up to 20,000 hours of use.

Sound is covered too, with built-in stereo speakers, and 1080p is supported so the picture looks crisp, even when stretching it to the limit of 150-inches. And a detailed remote is included too so you’re in full control, even from the back row.

Wireless Projector | Discover the Full Guide

Interested in reading a real case story about a school who made the switch from VGA to cableless HDMI? Check out our use case and deployment of Airtames at the University of San Diego.

There’s no need to throw out an old projector just because it uses VGA, DVI, or HDMI cables. This Wireless Projector Guide will go over a few of the reasons why.

First, let’s talk about the perks of going wireless. After that, we’ll share how you can make a projector wireless using Airtame’s cableless HDMI solution.

Then, we’ll cover the different types of wireless solutions you can choose from. To see examples of the wireless streaming in action, check out our deployment pages – for Business and Education.

Why go wireless?

It’s one thing upgrading from an older cabled solution to a newer cabled solution, but quite another making the jump into wireless. It can seem complicated and perhaps unnecessary.

When you consider the perks of going wireless and how easy it is to do, however, you might change your mind.

No more cables!

Going wireless means you won’t need any cables between your computer and the projector in order to share your screen. That means you and your guests no longer have to fumble around with a tangle of wires. If you still need convincing, take a look at our cables vs. Airtame comparison article.

Shorter transitions between presenters

Less time plugging and unplugging cables means that getting through multiple presentations is easier and faster.

If you choose a wireless solution, like Airtame, that uses software to connect your source device to the projector, presenters won’t even have to leave their desk in order to switch presentations from one computer to another.

It’s BYOD friendly

With cables, you have to make sure to have a cable and converter for each type of computer or phone. You’ve experienced this issue before, right? Even with several adapters on hand, you risk that there will be someone who cannot connect to the projector because they don’t have the right adapter.

Stream to multiple projectors

With the Airtame app, you can mirror your screen to multiple projectors from one computer, so long as each projector has an Airtame plugged in. This is a great option for large lecture halls that have multiple projectors and projector screens in one space.

Convinced that wireless is the way to go? Let’s go over how to turn your current cabled solution into a wireless one.

How to make a projector wireless with Airtame

There are a range of wireless adapters available that can convert your current cabled projector into a wireless one.

With Airtame, making your projector wireless is easy. Plug Airtame into the projector’s HDMI port, download the app on your computer, and connect the Airtame to your WiFi network.

Your projector doesn’t have an HDMI port? Luckily, Airtame works with your VGA and DVI ports with the use of an adapter (pictured below).

From VGA to HDMI

Many older projectors still in use were made with VGA technology. By now, VGA is an outdated technology compared to newer digital standards like HDMI. However, this doesn’t mean you need to throw out a projector that works.

A VGA to HDMI adapter is all you need to use an older projector with Airtame’s wireless technology. Airtame’s VGA adapter doesn’t plug in directly into the projector, but instead uses your projector’s VGA port to connect. Read more about how adapters work with Airtame on our help page.

From DVI to HDMI

With DVI projectors, you can also use a DVI to HDMI adapter to convert your old cabled projector into a wireless streaming solution.

The process is the same as described above: Connect the DVI adapter to your projector’s DVI cable, and then connect to the Airtame device. With this simple tweak, your projector is ready to go wireless.

From HDMI to cableless HDMI

If your projector has an HDMI port, it can connect to many devices with a cable and adapter. However, the hassle of connecting your devices to cables still remains. To get cableless HDMI, use Airtame’s HDMI to HDMI adapter.

Connect the HDMI adapter to your projector’s HDMI cable, and then connect Airtame device to the adapter.

Keep in mind that most wireless adapters require an electrical outlet for power. ? If you use Airtame and your projector can provide 5V and 1A, it might be possible to power your Airtame through the projector’s USB port.

Types of wireless projectors

There are lots of options out there when it comes to projectors. This is a quick go-to guide on the popular types of wireless projectors.

First, there are 3 main uses for projectors: home theater, office, and education. In this section, we’ll focus on key differences between home and office use.

Home projectors

Projectors designed for home theaters come with some swanky features that are really not needed in a work or school environment. For example, Epson’s popular PowerLite 3020e projector comes with 3-D functionality.

What is important in a home use case is that the projector can handle video smoothly.

A home theater environment is usually smaller and has less ambient lighting, so the projector does not need to have especially high brightness levels. Of course, this all depends on the ambient lighting in an individual environment. Check out this impressive guide to lumens by the Projector People here.

A projector for office use has a different use case that affects the features you’ll need.

Work projectors

For offices, streaming from computer and mobile devices to the projector screen is the main use.

It’s important to choose a projector that can handle multimedia content. Since video is not the primary focus, screen resolution does not have to be especially high. In most cases, a resolution of 1024 x 768 px is enough for those in the back of a larger room to see the finer details of a presentation.

That said, there also tends to be more ambient light in an office setting, which means you’ll need higher brightness levels (i.e., more lumens).

Now that we’ve gone over the main difference between home and work use, it’s important to know the different types of technology used in wireless projectors.

Transmitters and receivers

Most wireless projectors on the market use a transmitter and receiver system. A transmitter, such as a USB stick or dongle, is plugged into your computer (or other source device) and the projector has a built-in WiFi chip to act as a receiver.

The benefit of this is that you do not have to download any software on your computer.

For example, Roku’s streaming projector SPR 1000 is made for home-use to stream media subscriptions like Netflix. It comes with a Roku streaming stick that plugs into your computer.

An office-grade option in this category would be a projector like Epson’s PowerLite 1700 Series, which offers built-in WiFi and a plug and play USB stick for PC and Mac.

Software and WiFi

Some projectors offer built-in wireless connectivity using computer software and a WiFi network, although the exact setup varies. The benefit is that you do not have anything plugged into the source device.

An example of a top-shelf projector in this category is the Optoma TW766W Wireless Projector. This projector offers a Mac client software you download and which will locate the projector’s IP address to connect. The drawback is that this option can run you up a bill of around $3,000.

Airtame wireless adapter

The beauty of Airtame’s wireless solution is that it works with projectors that do not have WiFi functionality installed directly in them. It also does not require you to plug anything into your computer.

Since Airtame works with an app over WiFi, it’s a cross-platform solution that works for Mac, Windows, Linux, Android, and iOS.

This is possible because the Airtame app connects your computer to the Airtame device that is plugged into the projector, as shown in the image below.

If you prefer an Ethernet connection, you can use Airtame with an Ethernet adapter. This is optional, although we do recommend it to get the most stable performance.

Mobile apps

It’s worth noting that some brands offer mobile apps, like Epson’s iprojector mobile app. These kinds of apps let you present from your mobile devices. The bonus of Epson’s iprojector app is that it lets you annotate directly on the screen while you’re presenting.

Airtame offers a mobile app, as well, that lets you stream images or PDFs from your phone or from Dropbox. The perk is that if you don’t have WiFi available where you’re presenting, you can connect directly to the Airtame’s own WiFi network and present. At least so long as you do not need internet.

Wireless projectors in education

Projectors are more often associated with educational institutions, probably because education is where you’re more likely to find large rooms and auditoriums that require a large projector screen.

Setting up projectors in schools and universities has its own challenges. Here are some things to consider.

At schools, for example, multiple student presenters need to easily and quickly switch between different computers. In this respect, cables are a major hassle.

Another obstacle is the physical installation of the projectors and cables. Unlike at home, schools have very large rooms, especially lecture halls that have high ceilings. To solve this issue, many schools hide meters of cables in the walls, floors, or ceilings, but there are some buildings that cannot be drilled into.

When you have a lot of teachers and students using a wireless solution, you need a way to minimize the risk of connecting to the wrong projector. Airtame, for example, gives the option to use a pin code to start a stream, which will appear on the projector screen. Learn more about Pin Code Connect here.

Another issue you might encounter in a school or university is the management of multiple projectors. We’re currently developing the Airtame Cloud Platform that will allow IT administrators to oversee multiple Airtames from the comfort of their own desks. Read more about the Cloud Platform here.

How to make the projector wireless?

The first step to making your projector wireless starts with purchasing all the necessary hardware. To do this, you will need a wireless transmitter and receiver kit, an HDMI cable (for connecting a computer or laptop to the transmitter), and a power cord for each device you use.

Once you select the wireless transmission method mentioned below, the steps to make your projector wireless are fairly simple.

  1. Select the type of transmission system you are going to use.
  2. Connect the wireless receiver to the projector.
  3. Connect the transmitter to a computer or video source.
  4. Start projecting wirelessly.

So let’s start helping you decide which transmission method is best for you.

What is wireless projection?

Wireless projection allows you to broadcast your presentation from anywhere by sending signals through walls using radio waves instead of being limited to a cable connection. Three types of wireless projection: via Bluetooth, via HDMI transmission and via WiFi.

Using a Bluetooth receiver to make your projector compatible with Bluetooth

Bluetooth receivers are useful if your projector does not have an HDMI port. For this method, you need to purchase a Bluetooth receiver that plugs into your projector’s USB port. You will then need to connect the receiver to your computer or laptop.

Using the HDMI transmitter and receiver to wirelessly communicate with the projector

HDMI transmitter/receiver is a great option if your computer or laptop has a free HDMI port that you can use to connect your device. You will then need to connect the transmitter to the computer and the receiver to the projector using an HDMI cable, just as if your projector was wired or connected to a monitor.

You need to expand your computer displays so that the transmitter is recognized as a second monitor, and you’re done!

Using a Wi-Fi dongle to connect the projector to a wireless network

See also:

Wi-Fi dongles are a great option if you want to make your projector wireless but can’t connect an HDMI cable to your device. They are supplied as USB sticks and allow for easy installation and simple operation with most projectors.

After connecting, you will only have to configure the software that will be used on your computer or laptop.

Frequently asked questions about how to make the projector wireless

How I struggled with connecting the projector and found as many as 7 ways / Habr

Step-by-step setup: connecting the projector to a computer, smartphone, tablet. Detailed instructions

I tried to state and argue each section so that even a non-pro would understand the issue of connecting and setting up the projector.

Projector manuals do not always describe all the features of the equipment. Especially those related to interaction with other devices. To become more savvy in this matter, the tips that I give, based on my experience, will help. And by analyzing authoritative sources that I trust.

3 ways to connect the projector with a cable

It’s no secret that a cable connection is not the only way to transfer images to a projector. No wonder many devices are sold with a built-in Wi-Fi module. However, the cable option is the best in terms of image quality on the screen. If you are planning a desktop installation, and you are not going to hang the projector on the ceiling, then the best option would be to connect via HDMI, VGA or USB. However, please note that some budget models do not support USB. This is clearly stated in the user manual [1].

But be that as it may, you can connect a modern projector using three interfaces.

USB connection

USB port is a universal solution for powering devices and transmitting a signal. Modern projectors have at least 2 such connectors: type B and A. To broadcast a picture, you need the first one. It is square in shape with beveled corners. For reference: next to them are often the letters PC, an image of a computer, etc. Before transferring the picture, you may need to install the driver. In this case, install the software first, then connect the cable. You can connect the PC and the projector without turning off the devices.

VGA and HDMI cables are more suitable for picture transmission. If you broadcast video via USB, slowdowns are possible, but such a port will be a good solution for showing a presentation. With USB connection, there is a signal transmission in 2 ends, you can control the slides using the projector’s remote control.

USB type A I often use:

But this is not a panacea, you can try a few more options.

HDMI Switch

HDMI cable gives you a higher quality Full HD picture. It eliminates freezes during video transmission. Such an interface allows you to connect a PC to the projector without turning them off, but it is better to play it safe and start the equipment after connecting the connectors with a cable, since a burnt port is always unpleasant. Therefore, you need to follow the instructions: first turn on the projector, then the computer [2].

Some laptops and ultrabooks have mini or even micro HDMI instead of full size HDMI. In this case, you will need a cable with connectors of different sizes at the ends.

The only disadvantage of HDMI is the limitation on the length of the cord. The manufacturer is unlikely to equip the device with a cable longer than 3 meters. This means that a laptop or desktop PC must be somewhere nearby, which is not always convenient. On sale there are cables up to 15 meters long, but they are quite expensive. In addition, as the length increases, the likelihood of quality loss during video transmission increases.

VGA connection

VGA technology appeared much earlier than HDMI, it is not suitable for broadcasting high-quality, by today’s standards, pictures. You can count on HD quality, but you won’t be able to squeeze out FHD anymore. The VGA cable does not transmit sound. If you need to watch a video, you will have to transmit audio over another channel, for example, using an A/V cable [3]. On the projector, in addition to the input, there can be an output VGA that transmits the signal received from the PC to another device. In this case, the projection device acts as a splitter.

4 ways to connect the projector wirelessly

Most wireless options are based on Wi-Fi. It is easier to ensure signal transmission if there is a wireless router in the room. Although there are also options for direct transmission of video content from a phone / laptop to a projector. The use of Wi-Fi technologies is relevant when broadcasting slides. Watching movies with their help is problematic – the quality of the picture is lost, there will be data transfer delays. And the broadcast “over the air” noticed two advantages:

WirelessHD technology stands out among the considered wireless solutions. She is trying to maintain the transmission quality of the HDMI cable by replacing it with a transmitter and receiver.

How to connect using Miracast

Miracast provides Wi-Fi signal transmission between devices without intermediaries. You don’t need a router or access point to connect the projector wirelessly. The source and destination must be certified. You can transfer a picture from a smartphone or other Android device, as well as from Windows devices. Adherents of iOS can use a similar technology called AirPlay [4].

If your projector does not support Miracast built-in, you can use a MiraScreen or AnyCast adapter. Mirascreen is like a big flash drive. I insert this gadget into the HDMI port of the projector, before that I connected the power cable and antennas to the adapter. I use the USB port for power.

Turning on WiDi Tricks

Intel has come up with a technology that is in many ways similar to Miracast, called Wi-Fi Direct (WiDi for short). It is also used to connect projectors via WiFi. It is aimed at users who prefer laptops and other equipment with Intel processors. To use the technology, you need to install Intel’s Wireless Display program on your computer. WiDi can also be used to transmit a signal from Android devices. If an adapter is involved in broadcasting images, then this can also be MiraScreen or AnyCast.

Wi-Fi connection

The picture from the phone will be displayed on the wireless projector when Wi-Fi is available in the room. The projection device in this bundle will play the role of an access point. The signal will go, for example, through the router. The connection includes 2 steps, you need:

  1. Set the projector to Wi-Fi reception mode.

  2. Select a device in the smartphone settings. There will be a PlayTo item (Wireless connection to the display) or something like that (depending on the phone model).

The laptop is configured differently. For most models, a function key, for example, F1, is responsible for switching to a TV / projector / separate monitor. Paired with Fn, it activates the desired mode. A detailed guide on this issue was well described by Andrey Kireev in his article [5].

Connect via WirelessHD

By the end of the name HD, you can guess that the technology provides high quality video transmission. The standard supports 3D and 4K. The signal, unlike Wi-Fi, does not pass through walls, but goes around obstacles – people, vertical structures, chairs, etc. Stream transmission is designed for the presence of the source and the recipient in the same room. The broadcast distance is limited to 5-30 meters, that is, we are talking about replacing the HDMI cable while maintaining the quality of the video signal transfer. To implement the technology, you will need a set of equipment consisting of a transmitter and a receiver.

Arguments for and against WirelessHD I have listed in the table:

Does not compress information during transmission

2 algorithms for connecting the projector to a PC

By cable The computer must have two video outputs. You need to connect the PC and the projector with a cable, turn on the equipment and proceed to setting up the computer. Further, the algorithm depends on the OS:

a) PC settings for Windows 7: right-click on the Desktop – open Screen resolution. In the “Multiple Screens” menu, select the broadcast method: duplication, only the second screen, stretch the Desktop over two screens. In the Control Panel, open the sound settings and in the devices, select the projector as the default sound source.

b) Windows 10 has a wonderful Win + P combination that opens a window with a choice of translation method [6]. To adjust the sound, right-click on the speaker icon in the system tray, open the sound options and select the projecting device.

Over the air The projector needs to be set to wireless mode. Next, in Windows 10, click Start → Settings → System → Display → Multiple displays → Connect to a wireless display. The discovered devices will appear in the right part of the window. A detailed guide on this issue spied here.[6]

How to connect to smartphones and tablets

For wired connection, it is desirable that the projector and smartphone support MHL. It is optimal if both devices have miniHDMI ports, but this option is rare. More often you have to use an adapter that connects mini- or microUSB to HDMI.

How to connect your tablet or smartphone to the projector via Wi-Fi – described above. If your tablet or phone is running Windows, you will need additional software, such as the aforementioned Wireless Display.

Basic projector settings for Wi-Fi

I will give an example of setting up one of the projectors with an adapter for synchronization with a smartphone. To do this, turn on the projector and configure it using the remote control, while the menus are displayed on the screen. So, the algorithm is as follows:

  1. In the “Application” menu, select “Wi-Fi Display”. We get into the EZCast window.

  2. When using the wireless connection for the first time, download and install the EZCast program on your smartphone, for this you can scan the QR code from the screen.

  3. Turn on Wi-Fi on the projector, connect it to an available network.

  4. Turn on Wi-Fi on your smartphone, connect to the same network.

  5. We connect to the adapter using the EZCast application.

Power Point is still relevant for projecting presentations. It allows you to make a report without showing the audience part of the file, using a “cheat sheet” [7].

In conclusion, I would like to note another wired solution for connecting a smartphone to a projector – Unnlink converter cable. On the one hand, the accessory has HDMI and USB to power the adapter, on the other, there is a limit switch with the ability to connect to Lightning, Micro USB or Type-C. The Unnlink converter cable supports MHL, you can control the data transfer with EZCast or other application.
