Eli5 4k resolution and aspect ratio

563 views

Okay, so I have a 5700xt and a 24inch 1080p monitor and I’m thinking of getting into 4k. However, I’m struggling to understand how it works.

So my pc is currently on 1920*1080. Everytime I Google 4k, the resolution mentioned is far larger. For example 3840*2160. If I change my resolution on windows everything gets either larger or smaller. So is 3840*2160 really zoomed in or out if the TV is also 24 inch? Everytime I Google a picture it suggests you see more of the same image of it’s in 4k. Or is 1920*1080 just the aspect ratio and the pixels are infact really condensed?

Sorry for the confusing paragraph, I’m really struggling to get my head around 4k. Logically, I’m presuming the pixels are condensed into the same space but the ratios are confusing me.

Thanks for the help!

Aspect Ratio is just the ratio of how many pixels horizontally compared to vertically. A lot of stuff is 16:9 these days, although 16:10 and 3:2 are more and more common.

4k resolution is a nickname for 3840x2160p. It is 4 times the size of a typical 1920×1080 resolution (twice as wide and twice as tall, effectively 4 screens).

If you have a monitor that is a certain size as a 1080p monitor, and then take an identically sized monitor that is 4k (i.e., a 27 inch 1080p vs a 27 inch 4k), then you basically are just smooshing more pixels in the same place. If everything was the same number of pixels in size, it would all appear smaller on the screen.
