Posted September 18, 2016 I was wondering when you for instance are browsing the web on your 4k screen, does it make the 1080p and 733x542 etc images which you see a lot on websites look worse because of upscaling? (Btw I also use 150% standard zoom in windows settings.) So all pixels should be stretched a bit instead of just using the 733x542 pixels and look really small on my screen. I know though that when you display 1080p content , upscaling wouldn't effect the quality at all, as 4k will be exactly 4 times the pixels of a 1080p screen. So for every 1 pixels, 4 will be turned on now. But how will this work with other resolutions which don't scale that nicely? Link to comment Share on other sites More sharing options...

Posted September 18, 2016 yes, it's worse it's exactly the same as running 720p game on a 1080p screen Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Posted September 18, 2016 That depends on the size of the display too. If you have a 21" 4k monitor, chances are 1080p will look alright, but it won't look too great on a 28 or 32" 4k monitor. Since 3840x2160 is the size of four 1920x1080 screens, when a 1080p video is played at fullscreen, every pixel of the video will be effectively stretched across four pixels of the monitor. Depending on how close you are to the display (and, again, the size of the display), this could be either negligible or extremely noticeable. i5 12600KF | Zotac RTX 4080 Gaming trinity | Team Vulcan 2x16GB DDR4 3600 | ASRock Z690M-ITX/ac | WD Black SN850x 2TB Cooler Master NR200P v2 | ID Cooling Zoomflow 280 XT | SeaSonic Focus SGX-750 | Thermalright 2x140mm + 2x120mm aRGB LG C2 OLED 48" 120hz | Epomaker TH80 (Gateron Yellow) | Logitech MX Master 3 | Koss Porta Pro Comm Link to comment Share on other sites More sharing options...

Posted September 18, 2016 Had I the money, I'd probably buy a 4K panel, even though I'd have little chance of playing anything new at 4K. The additional resolution is a great help in surfing, and more productive uses such as video editing, writing, 3d, etc. Scaling probably depends. In the case of perfect multiples, there should theoretically be little discernable difference. In other cases, you may just have to live with the slight quality hit. In a decent video player, the quality hit with scaling 720p video should be minimal, in gaming, the video card should at least handle 1080P.

That's actually not necessarily true. It depends on the display. In theory 1080p content could be scaled in this way, but it is not implemented this way on most 4K monitors, interpolation is still used.

Posted September 18, 2016 In my experience, no. Everything looks practically the same because 150% scaling on a 27" 4K display gives it a relative resolution of 2560x1440. Which is the standard resolution for that size anyway. I have a blog! And a list of guides I've posted Link to comment Share on other sites More sharing options...

Posted September 20, 2016 To me, with a screen DSR > 4K because you can't browse internet on a 4K resolution and more importantly, if a game runs slowly in 4K, using DSR on a 1080p / 1440p screen you can still adapt the resolution lower Link to comment Share on other sites More sharing options...
