recently i bought theese hardware:
1) Gigabyte B450M Aorus M with B450 chipset
2) Ryzen 3 2200G
3) 2*8 DDR4 2666Mhz Kingston Fury
I have 30" CrossOver 30Q5 PRO Black monitor, that worked on previous hardware (Asus motherboard on AM2+ socket) without any problems 2560*1600 under Windows 7 64bit.
Now, under could not give more than 1280*800 under Windows 10 64 bit.
Drivers (latest from amd.com) and windows setting tell me that it is maximum resolution.
Friends, i need your help and solution
