Want to know what screen resolutions are and why they’re important? Read on to find out why.
What Does Display or Screen Resolution Really Mean?
Images are shown on computer screens by using a huge number of tiny squares called pixels. To arrange the pixels, a horizontal and vertical grid is used. The horizontal and vertical pixels are shown as a way to measure the screen’s resolution.
Most of the time, screen resolutions are between 1024768 (or 1366768) and 19201080. So, the screen can be seen with 1024 pixels on the left and 768 pixels on the right (or vertically with 1366 pixels, and so on).

Screen size is different from screen resolution.
Besides the resolution, the size of the screen is also important. The diagonal of your screen tells you how big it is. One inch is the same as 5′′, 10′′, etc.
It has nothing to do with the size or quality of the screen. Let’s say you had a 10.6-inch tablet and a 24-inch desktop monitor, both of which had 1920 x 1080 resolutions. The resolution of both devices is the same, so they can both show the same image. The only difference is that because the computer monitor is bigger, the image will look much bigger on the screen.
Also, because the dots will be closer together, the larger image will look less clear.
Even if the size of two monitors is the same, they can still have different resolutions. If you have a high-resolution monitor, this resolution will let you fit more on one screen. Because the pixels are closer together, the images will be smaller, but they will still be sharper.
Screen Resolutions of 1440p, 2K, 4K, and 8K
When high-definition TVs became popular, manufacturers came up with a way to talk about display resolution. Most computer monitors will show 720p, 1080p, 1140p, or 4K as a number. In the same way, the “p” or I shows whether the display is interlaced or progressive scan.
One reason these numbers are also used for computers is because a computer monitor can show a higher-definition picture than a TV. Display numbers are always the number of horizontal lines on a screen.
Quad HD is the name for 2560 x 1440, which is usually found on gaming monitors and high-end phones. 1440p has four times the resolution of 720p HD. To make things even more confusing, many high-end smartphones have a resolution of 2,960 x 1440, which is part of the 1440p range.
4K or 2160p
People often use the terms UHD, 4K, and Ultra HD to talk about this resolution. It has a high display resolution and is found in high-end TVs and computer monitors. 2160p is called 4K when the width is close to 4000 pixels. So, 4K HD has four times as many pixels as 1080p Full HD.
8K or 4320p
With a resolution of 7680 x 4320, “8K” technology gives you 16 times more pixels than a regular 1080p FHD or “Full HD” TV. For now, the only 8K TVs you can buy are from LG and Samsung.
Here’s a test video that you can watch to see if your computer can handle an 8K video:
Consumer devices don’t have to have a 2K resolution yet.
In the world of film, a 2K resolution is 2048 x 1080. Consumers, on the other hand, would think it was 1080p. Also, some manufacturers of displays call screens with a horizontal resolution of more than 2000 pixels “2K,” even though they have a resolution of at least 25601440. In this case, the settings for this device are 1440p, which is also called Quad HD, not 2K.
The term “2K resolution” can be used to describe a TV, a monitor, a smartphone, or a tablet. It would be wrong to think that it only applies to these devices, though. Most likely, the real resolution is 1440p or quad HD.
Can I watch videos with a higher resolution on a device that has a lower resolution?
You might worry about whether a high-resolution video can be seen on a small screen. Can 720p TVs display 1080p videos? Yes, indeed! Any video can be watched, no matter how high, medium, or low the resolution of the screen is. If the video has a higher resolution than what your screen can show, your device changes the resolution of the video to match the resolution of your screen. One way to do this is by downsampling.
For example, if your screen can only show 720p and the video is 4K, the video will show at 720p.
Display orientation vs. the aspect ratio
The way you look at a screen depends on how it is set up. Landscape and portrait are the most common ways to set up a screen today. A display with a landscape orientation is wider than it is tall, while a display with a portrait orientation is the opposite.
Most of the time, our computer, laptop, TV, and many other screens are set up in landscape mode. For example, the screens on our smartphones are smaller, and we usually use them in portrait mode. However, since they are easy to turn, they can also be used in landscape mode.
The aspect ratio of a screen is the length of its long side compared to the length of its short side. So, when you look at a landscape screen, the aspect ratio tells you how wide it is compared to how tall it is. In portrait mode, the aspect ratio is not used to describe screens or other rectangles.
How does the resolution of your screen help you?
If you’ve read this far, you probably already know that the higher the screen resolution, the better. It’s not always like this.
If two screens were the same size, but one had a higher resolution than the other, the higher resolution screen would show more and need less scrolling. It also has more edge.
Because of this, the picture will also get smaller. You might want to zoom in on the picture because it’s hard on your eyes. This lowers the resolution and shows less on the screen. Why buy something with a high resolution if you can’t use it right?
This is especially likely to happen on smaller devices like smartphones and tablets. We’ve also talked about whether or not your phone’s screen needs to be 4K.
You might think you shouldn’t pass it up just because it’s there, even if you don’t really need it. This is because of a few things. One of the main ones is money. No matter what size the screen is, screens with a high resolution cost more.
Another reason has more to do with how things work. For a high resolution, you need more resources. When you set your screen to 60Hz, the video card updates the frame 60 times per second. People don’t usually use 60Hz, and if they can, they would rather use 120Hz or 144Hz. When the resolution goes up, it puts more strain on the video card. Each pixel updates at the same time, so there is a lot of refreshing going on. There are more pixels when the strain is higher.
1920 x 1080 x 60 FPS is probably more than enough for medium-end video cards, but higher resolutions are hard to play on high-end video cards.
