Hello guys, i hope someone can help me here, its a problem that i've been having from a long time... my monitor native resolution is 1366x768, but using my video card (Amd Radeon) sofware, i can use the super virtual resolution to go futher..

I can use 1600x900 resolution, but when i go for 1920x1080 it appears "unsupported input", the question here is, as the title says, i can use 2560x1440 resolution on games and on windows but i can't use 1920x1080, and i remember that some months ago after i formatted the PC, i could use the 1920 resolution...

Please, someone give me some guidance.


Monitor : 1950w AOC
Video Card : RX 580 8GB

Welcome to the forums, newcomer!

I'm assuming you're working off of Windows 10 while on that legacy display? If so, have you tried manually installing the drivers meant for the display in compatibility mode? i.e, Right click installer>Properties>Compatibility tab>Windows X(from the drop down menu)?

You should then use DDU to uninstall your GPU drivers then reinstall with the latest drivers found off of AMD's support site, manually, i.e, Right click installer>Run as Administrator.

1366/1600=0.85375
1366/1920=0.71145833333333333333333333333333(repeating)
1366/1440=0.53359375

The ratio to 1920 is the only one that has a repeating decimal. I believe this has something to do with it. Either impossible to display correctly or too computationally expensive.

Yes, i'm using W10, by drivers you mean the AMD drivers for the video card? If so, i should use compatibility for w8 or 7?

I did the DDU 2 weeks ago, but it remains impossible to input 1920...

I'm sorry if i can't fully understand what you mean, i'm new to these hardware/software and english is not my native language, but i'll for sure try my best...

But how could i do it in the past, and not anymore now? I remember being 100% able to select 1920, but someday it just stopped working, after a gpu driver update maybe...
