What 1080p: What Is 1080p Resolution? FHD Explained

What is the difference between 1080 p and 720 p resolution?

When it comes to video quality, we’re all used to seeing a collection of numbers splattered on our television packaging, on laptop screens and on streaming services, but what do they actually mean?

Whether it’s 1080p, 4k, 720p or 360, the numbers can all start to blur into one, making it difficult to differentiate and understand what the actual difference is. If you’re sick of seeing a bunch of numbers and not understanding what they mean, you’re in the right place.

At DEXON, we make it our responsibility to ensure you understand what you’re in for when you select a 1080p, 720p or 4k monitor. Today, we’ll be discussing what TV resolution is, the difference between 1080p and 720p and why this matters to your viewing experience.

What does TV resolution mean?

Before we start getting into the specific numbers, it’s very important that we discuss the primary topic, which is TV resolution. Both 1080p and 720p refer to the TV resolution which is defined by the number of vertical and horizontal pixels. Putting it simply, TV resolution will determine the quality of the picture on your TV.

Generally speaking, the higher the resolution number, the higher the quality. On higher resolution televisions, images will appear a lot crisper and allow you to identify smaller details, whereas lower resolutions like 360p and below will appear relatively blurry with little to no sharp edges to your image.

When we talk about TV resolution, it’s important to distinguish the difference between native and image resolution. Native resolution refers to the TV or monitor’s resolution and what it can physically provide to viewers. Image resolution refers to the resolution of the image signals sent to the TV via a HDMI cable. This difference is the reason why a 4K UHD TV may display a high-definition image when you go to watch a film or select something from your TV guide.

What does the “p” stand for?

While many would naturally assume that the “p” in these numbers stands for pixels, you’d actually be wrong. P stands for progressive scan (also known as non-interlaced scanning). This refers to the format that displays, moves and stores moving images when all lines in the frame rate are sequential.

In other words, the progressive scan means that all the lines in a frame appear at the same time. With progressive scanning, the image frame refreshes every cycle. This makes images very high quality. 

What is 1080 p resolution?

Now that we understand the specifics, let’s get onto the nitty gritty. So what is 1080p? 1080p is a type of high-definition television that displays 1,980 pixels horizontally across a screen and 1,080 pixels vertically down the screen.

With 1080p, it usually pimples a wide aspect ratio of around 16:9 and a resolution of 2.1 megapixels. 1080p is one of the most common streaming resolutions on websites like YouTube, as it offers high resolution without eating up too much internet bandwidth to display the quality.

Although 1080p is often marketed as 2K resolution, it’s important to note that these are different as they have different aspect ratios and resolutions.

As with other resolutions, this number refers to the total number of pixels displayed across a screen at any time. To understand how many pixels this is, you’ll need to multiply the vertical number by the horizontal. So, that would be 1,980 x 1,080 for a 1080p television. That means that there are 2,138,400 pixels on a screen in a 1080p high-definition television.

 

What is 720p resolution?

720p resolution is another example of standard high-definition television. With 720p P&A television has a total of 1280 horizontal pixels and 720 vertical pixels. The aspect ratio for a 720p television is 16:9.

To work out the number of pixels on a 720p compatible television, you need to do the same equation applied to 1080p. To do this you can simply multiply 1280 by 720. That means on a 720p television, there are 921,600 pixels at any given time. 

Although part of the high definition club, 720p doesn’t usually compare to 1080p on today’s computer monitors. Anyone who has ever switched from 1080p to 720p resolution will tell you that the difference, although immediately very minor, makes a big difference overall. However, there are some positives.

720p takes up less bandwidth and data than 1080p or 4K, so is a lot more budget-friendly for anyone streaming content via their mobile data on their smartphone or tablet.

1080 p vs. 720 p: what are the differences?

Now you understand what both 1080p and 720p mean, let’s discuss some of the key differences. Here are some of the key differences you may notice if you have a keen eye:

  • Picture quality – Although there’s very little difference between the image quality of both 1080p and 720p, switching between the two will expose that 1080p results in a sharper clearer image than 1080p. However, this is minimal so if you’re concerned about opting for a budget-friendly 720p monitor instead of a full HD monitor, you’re unlikely to encounter any major image issues.
  • Pixel count – Of course, one of the most noticeable differences between the two resolutions is the pixel count. 720p has a pixel count of under a million, whereas 1080p has well over two million pixels. This has a slight impact on image quality and clarity.
  • Data usage – Data usage is one of the most significant differences between 1080p and 720p. When talking about data usage, we’re referring to how much data is required to stream a film or TV program per hour. For 720p, a 60 frame-per-second video will use around 1.86 GB an hour, whereas 1080 will use around 3.04GB an hour.

Where do we use 1080 and 720 resolutions?

We tend to refer most heavily to 1080p and 720p resolutions with anything involving a monitor or television. This includes streaming, watching satellite TV or even gaming. The two resolutions make the most difference when it comes to internet streaming, as each uses up different amounts of bandwidth which can impact internet speed.

The next time you’re browsing through YouTube, for example, try changing the resolution to a lower setting and see how quickly your video loads in comparison to higher resolutions. These two resolutions also have a significant impact on gaming.

This is because 1080p devices require less anti-aliasing to make images appear smoother and more cohesive due to the higher pixel count. Anti-aliasing tends to slow computers down, so opting for a 1080p gaming set-up can have a positive impact on your overall gaming experience.

What is 1080p? | Ubergizmo

1080p means 1920×1080 pixels of resolution; it is also known as Full-HD, FHD, WUXGA and BT. 709, and applies to TVs/displays/media resolution in which the “p” means that the resolution is “progressive” which means that there are truly 1080 vertical lines.

1080p implies a display/content aspect ratio of 16:9 and represents 2M pixels (2073600 to be exact). FHD/Full-HD is the other most-used term to market this resolution. As a reminder, “HD” was introduced as 1280×720 pixels, also known as 720p.

1080p only describes the resolution and does not imply the refresh rate for displays, or the frame rate for video content. These details are encompassed in different standards of broadcasting or video-encoding, that generate a 1080p resolution image.

1080p was and still is a standard for many things, including Blu-Ray content, Televisions, Computer screens and Mobile devices displays – just to cite the most popular ones. 1080p and FHD/Full HD are used interchangeably in “technology” communication materials, and they mean the same thing.

Can content that is not 1080p be played back on a 1080p display?

It’s possible. Every display system has a “native” resolution, which is its number of pixels. Any media content can be resized and filtered to fit any native resolution.

If the display resolution is superior to the content resolution, the image quality won’t be improved by much. There are ways to slightly enhance the image during the up-scaling phase, but it won’t be equal to content created for the target resolution.

If the display resolution is inferior to the content resolution, the resizing will yield a best-possible image quality for that display. This is down-scaling. Both up-scaling and down-scaling are part of video scalers.

Although most good video players have some image downscaling capabilities, not all of them can upscale an image to a resolution that was possibly not in existence when they were manufactured. For example, many Blu-Ray players were sold well before 4K became a standard. Therefore, they have no awareness of that resolution, and cannot upscale to it.

What’s the difference between 1080p and 1080i?

1080i and 1080p can cause some confusion, although the use of 1080i is on its way out. “i’ stands for “interlaced” (and “p” is “progressive” as we said earlier).

The difference is that 1080i displays have only half the vertical resolution of 1080p, so ~540 (actual) lines. They can display 1080p content by “interlacing” the images lines, every other frame.

This results in a slightly better image than having 1920×540, but it is noticeably not as good as true 1080p. This interlacing technique was widely used when analog displays were very common and yet unable to physically achieve 1080p resolution. 1080i isn’t used much these days, but you may bump into it from time to time.
