My r9 390 not recognizing 4k tv resolution only up to 1680x1050
this was working before i update to crimson drivers but i have not reverted back to catalyst and it still showing only up to 1680x1050
if you mean you have rolled back and still shows a lower then 4k resolution , then windows resolution needs changed , right click desktop and select display settings and change your resolution to what you want
Well i got it working now thanks though.
