1080p @ 144 hz on 1440p monitor and AMD card - can't get full screen scaling???

Maybe the scaling options are for HDMI, but you won't be able to get 1440p @ 144 Hz with HDMI.

Add 1920x1080 @ 144 Hz as a detailed resolution using "LCD standard" timing. Then restart and make sure GPU scaling is disabled. If the monitor won't display anything when you switch to 1920x1080 @ 144 Hz, then it doesn't support non-native resolutions.

Thanks, I'm gonna try that now, btw what does the
"CEA-861: 5 detailed resolutions, 3 data blocks"
in my Extenion Blocks mean?

By making sure I have GPU scaling disabled you're talking abou the GPU scaling option within the ATI drivers right?

I did mess around with CRU and also the ATI driver patchers that would remove the pixel clock limits a lot in the past, since I had an old QNIX QX2710 monitor until a week ago when it finally died after a few years of use, most likely because I had it overclocked to 100 hz all the time using CRU + the patcher, which made some components on the monitor's mainboard heat up more than they'd usually do at 60 hz. We took out the mainboard recently and a friend of mine who knows a lot about electronics is currently trying to fix it.

Anyways I just wanted to add that since I figured it MIGHT have something to do with the issues I'm seeing right now (scaling not working at 144 hz) but I'm not sure.
