Why Can't I Run 2K / 1440p On My 4K Monitor? | Quick Tips

You can! But it won't be the best quality.

4K resolution is exactly 4 times the amount of pixels on a 1080p display, but it's 2.25 times the amount of pixels on a 1440p display. So scaling down to 1440p when your monitor has a 4K native resolution will result in slightly weird and blurry graphics 😄

Watch the video for a real quick explanation! 😁

never thought someone could actually answer my question this clearly :O Ty sir subbed instantly

[tyutyu]

Loved the example with the clear calculation. I instantly knew what is going on when you showed 4K devided by 1080P equals 4. Thank you.

Weird things is we can run 720p on 1080p on most TV or monitor (supported by default). If we divide the results of 1920x1080 with 1280x720 will give us 2.25 too. I know 720p on 1080p will looks blurry.

At last, a clear run down on scaling. Every other video is "click this button". Well done, SUBBED!

Ha this is just what I needed to see. I've got this weird issue where when I set cod to 1440p on my 4k monitor it LOOKS like a massive frame drop while still reading at high frames on the counter. This could explain it!

FINALLY I understand why 2k resolution looks off on my 4k monitor.. So it's essentially being scaled down to 2.25k, instead of a true 2k. Welp.. live and learn! lol.. Thanks for the very helpful video!! :)

Another tip to run 1080p on 2k monitor without ruined the experience is to set it at window screen 😊

I use my 4k 60hz native tv to game on with my rog ally i cap the fps to 60 and make the output 1080 and it works wonderfully now wanna go for a newer native 120hz screen so i can use my mini itx build on it for some high refreshrate 4k gaming

[TeamGun]

Doesn't matter what the numbers say, run 1080p on 4k and run 1440p on 4k and the 1440p looks better, sorry it just does.

Very cool. My question is why aren't 2k monitors actually half of what 4k I. Probably the same reason 4k isn't 4 thousand pixels across

[iNaneek]

Super helpful, thanks! To clarify, if I buy a 4k monitor and run 1080p it’ll work just fine? I want to buy a 4k monitor for programming but I want a 1080p for gaming. Also, if display through windows at 4k but through a game at 1080p would that work the same?

[liujohnson]

the explanation was so clear and acceptable, thanks

[xpotatomilk]

Well i never had any problems with gaming in 1440p using a 4K monitor

I would say just go for a 4k monitor and use DLSS/FSR or RSR if your pc can't support a few games in 4k resolution

[John-lrix]

Shouldnt it in theory be possible to render games at exactly half the resolution of 4k ? I know there are no monitors with that resolution, but for setting a resolution in game it shouldn‘t matter, right ?

[ensnButtn]

some new 4k gaming monitors actually give you the options to switch to 2k or FHD per OSD. it obviously also shrinks the screen. so on a 32 inch it can simulate a 27 or 24 inch display with different resolutions. works only great on oled though as the black borders can be a bit distracting.

[giveaway]

What about DLSS 4K or FSR2.0. Native 4K is never going to possible for Unreal 5 engine games at high fps.

[vanlendl]

Is there a simple way (upscale device ?) to show HD ready (notebook) signal or Full HD (bluray) signal on a 4k monitor?

[Cryptolorian]

I have just bought a laptop which has 3200 x 2000 resolution which is 16:10 aspect ration. The GPU wouldn't be able to perform well running this resolution when gaming. Can someone please tell me which lower resolutions would this high res scale down to? 1600 x 1000 is what I'm thinking but not sure if that's even a valid resolution LOL!

Or should I just buy a 1080p 165 hz monitor and play on that with the laptop display turned off?

Thanks peeps

My 4k TV says it doesn't support 1440p with my ps5, is the TV faulty ?
