However, these are usually denoted in another format where two numbers are separated by an X.
Lets see what these mean and which resolution is best suitable for what punch in of work.
Before starting with the numbers, we must be aware of the meaning of the resolution.
In this article, we cover everything related to resolutions, pixels, and why they matter.
Table of Contents
What is Resolution?
Pixel is the smallest square dot on the monitor screen which emits a specific color.
Whereas resolution is the total number of pixels that can be displayed on a monitor.
The number of pixels matters a lot when we are talking about image or video clarity.
More pixels in an image form a much sharper image.
This feature is denoted byPixels Per Inch (PPI).
Multiplying the 2 numbers gives us the total number of pixels on the screen.
For example, a resolution of 1920 x 1080 is known as1080p.
Note that the p at the end also means something.
The p in the resolution number stands for Progressive and the i in the resolution number stands for Interlaced.
The K just symbolizes the multiple of thousand (1000).
For example, 4K means 4000 pixels.
However, there arent exactly 4000 pixels when talking about 4K resolution.
We will get back to this later in this section.
The pixels on older display devices were painted horizontally back in the day and were interlaced.
This meant that the odd-numbered rows were painted first, and then followed by all the even-numbered rows.
The CRT painted the pixels so fast that the transition was invisible to the naked eye.
However, if you looked closely, you could identify the slight blurriness because of the interlacing.
When the technology changed for display devices, the interlacing technology was also changed to progressive scanning.
Therefore, the screen resolution naming changed from 1080i to 1080p.
The screen resolutions ending with K is an alternate method to name certain resolutions.
As we mentioned earlier, 4K essentially means 4000 pixels.
The same applies to 8K, for which the actual resolution is 76804320.
It is composed of 480 lines stacked one on top of another.
480p video is suitable for laptops, desktop monitors, and small format displays.
480p has a resolution of720480.
This means that it has 720 pixels horizontally and 480 pixels vertically.
The standard channels that we see on TV support this pop in of resolution.
If you want to buy a TV only for watching news channels etc.
it’s possible for you to for a 480p resolution TV.
Otherwise, your screen will seem distorted.
720p (HD) Resolution
720p has a resolution of1280720.
This means that it has 1280 pixels in a row and 720 pixels in a column.
Channels that stream movies or TV shows usually support this resolution.
So if you are a fan of that you should go for 720p resolution or higher.
With this resolution, you’ve got the option to go with larger screens as high as 60.
The optimal viewing distance depends upon the screen size.
The larger the screen size, the farther you should sit to have a clearer picture.
1080p (FHD) Resolution
1080p has a resolution of19201080pixels.
LCD and LED TVs have 1080p displays or higher.
It is double the size of a 720p display.
The blue ray movies we see are actually in 1080p resolution.
2K Resolution
2K resolution is 20481080 pixels.
However, this changed and everyone was on board when the 4K resolution was introduced.
4K/2160p (UHD) Resolution
4k is a 2160p and has a resolution of38402160which is insanely high.
It is usually good for gamers who play high-end graphics games.
Moreover, many movies are coming out on ultra-blue rays that have 4k resolutions.
YouTubenow also supports 4k videos.
Some devices can now also record in 4k resolution.
8K/4320p (8K UHD) Resolution
8K resolution is76804320pixels.
It is the highest achievable resolution currently available in the market at the time of writing this post.
This is a relatively newer resolution therefore any devices that display or record in 8K may be extremely expensive.
Other Resolutions
While there are other resolutions but we have only discussed the most common ones.
The rule of thumb is that the larger the resolution, the clearer the picture quality.
But higher resolutions will be more expensive too.
It is best to pick the optimal resolution according to your needs.
Of course, the resolution would still be poor, but the video will play.
But can you play high-resolution videos on low-resolution displays?
The answer is yes, the high-res videos will still be playable on low-res displays.
Most digital displays can downscale the resolution of high-res videos so that they can be displayed.
This is known as downsampling.
The resulting video will of course have a resolution equal to the max resolution supported by the display gear.
The bars are sometimes of different widths.
Nowadays, most of our display devices are widescreen.
These are written as 4:3 or 16:9.
Currently, there are even ultra-wide monitors and screens that have an aspect ratio of 32:9.
To compare, this screen is like putting 2 16:9 screens together side-by-side.
The screen would need to insert black bars to fill in the empty spaces.
That said, most people do not consider the aspect ratio of a screen when purchasing one.
