Hello guys,
so after hours and hours of skimming through Google and trying all kinds of stuff I've now finally registered here as a last resort, here's my setup:
Acer Predator XB271HU (connected via Displayport to a)
Radeon R9 280X
Win 10 Pro
Latest AMD driver 19.4.1 installed
So this Acer monitor has a 1440p native resolution and supports up to 165 hz (when activating it's 'OC' mode in the monitor's OSD), otherwise 144 hz.
Whenever I try to run a game with a 1080p resolution @ 144 hz, it will not scale up the image to a full screen no matter WHAT I try within the AMD Radeon driver or the monitor's OSD. It's like the scaling option is stuck to "Scaling Mode: Center"
Here are two images to show you what I mean:
CS:GO @ 1080p
![[Image: ZTSbaUr.jpg]]()
Old Command & Conquer @ 1080p
![[Image: Z1rrRfT.jpg]]()
My GPU scaling option within the Radeon drivers is currently set to 'off' however it doesn't matter if I set it to on and pick any of the scaling mode options. It won't scale it to fullscreen.
There's also an OSD option on my monitor: 'Wide Mode' can be set to either Full, Aspect or 1:1. Changing these options has actually never changed the image I'm seeing on my monitor and I've tried it while in-game, on desktop, using different resolutions / hz so I don't even know why the option is there when it's not doing anything.
But now comes the really weird thing:
I'm running 1440p at 144 hz as my native / desktop resolution.
As soon as I decrease it down to 60 hz within Windows display options, the whole GPU scaling will work perfectly fine and I'm able to play 1080p enlarged to full screen , but with 60 hz only. Whenever I increase that to anything above 60 (I have 85, 100, 120 and 144 hz available in the dropdown), it won't scale the image and I end up with the configuration you see on my screenshots.
I will also add that if I pick a 4:3 resolution of up to 1024x768, everything will work just fine as well (I'll have a 'full screen' with black bars left and right only, running at 144 hz, which is just the way it should be).
Does anyone know how to fix this?![Huh]( "Huh")
I'd be very very grateful... thanks !
