1080p games look worse on 4K monitor than 1080p monitor.

post #1 of 19
Thread Starter 
Hi,

I have had a BenQ RL2755HM 27" 1080p monitor for a year or so. Games on this monitor at it's native 1080p resolution looks pretty good. However I bought an LG 27UD88-W 27" 4K monitor two months ago and I very happy with it. The only problem is that when I try to play games on 1080p on my 4K monitor I can tell the graphics quality is substantially worse than if I would play on a native 1080p monitor.

I'm of course playing the games on fullscreen.

Can someone explain why this is happening? Did I forget how bad 1080p games look or is my 4K monitor doing something weird.

Cheap-ish monitors, on average, tend to not upscale resolution well. That may be the case with the 27UD88. Although 1080p didn't look too bad on Prad's review, more complex geometry might come out worse.

Your monitor is, basically, taking X pixels and mapping them onto a grid of 4X pixels, which might result in graphical artifacts or weird geometry.

It's actually very common. You would think that because it's a 4x difference it should do it perfectly well, but in actuality it very often will look worse.

It's the nature of modern screens, they aren't as flexible as CRT's of days gone by were (I still miss them). They are only designed to run at their native resolution. And it will look awful in anything but native resolution....

Also your eyes will perceive it as terrible too, coming from a glorious 4k image to 1080p is like going from a Bugatti Veyron to a fiat panda. biggrin.gif

It will look dull, edges will be even more obscured and artifacts will be amplified. It is good for retro-effect.

Out of curiosity, is there a reason you went with a Freesync monitor when you are running a 970? Do you plan on switching over to the green team?

I had a 780ti powering my 4k monitor and I just recently upgraded my video card o allow me to play games at 4k. When I was running the 780ti, I was playing all my games in 1440p since that was my previous monitor and I enjoyed that resolution. I would think your 970 could power a good amount of games at 1440p. If the 1080p stretched to your monitor looks bad, it might be worth a shot to see how that looks for ya.

If the 1080p stretched to your monitor looks bad, it might be worth a shot to see how that looks for ya.

Honestly I don't care about either freesync or G-sync. I just need a good 4k monitor for programming and this monitor seemed perfect at it's price point. I'm running my monitor without upscaling at all and the extra resolution gives me more space while using Visual Studio which is awesome. Also I sold my GTX 970 and bought two RX480s. But that decision had nothing to do with my freesync monitor. Now I pretty much play all my games on 4K at 60FPS. However I have to turn my resolution to 1440p or 1080 for games that do no support crossfire or has very poor crossfire scaling.

I was thinking of getting a GTX 1080 but there were none in stock for so long. The RX480 launched and it seemed a good idea to get two. Plus I really wanted to support AMD even if I had to bite the bullet and get ****ty crossfire scaling on most games.

Although I really miss the quiet water cooled 970. These two RX480 are loud as hell especially when they run on 5000RPM, I will probably sell my RX480's when the RX 490 comes out.

As for Freesync, I honestly don't see a difference when it's on or off. I still get screen tearing when V-sync is off. I don't know if I'm not doing it right or not. I see no difference with freesync.

Are you using GPU scaling or display scaling? If you are using GPU scaling... It can be substantially worse than the display scalar. If you cannot use display scaling because you are on windows 8 or 10... there are various workarounds to enable it.

Stuff looks like crap when its not displayed at its native resolution. Its why watching SD content looks like garbage on an HDTV, it's why if you try to run your desktop at a non native resolution for your monitor everything looks fuzzy and blurry and why your 1080p games look like crap on your 4k monitor.

Nothings wrong it just the way things work.
