gpg Posted January 7, 2020 Share Posted January 7, 2020 Upgraded my monitor from a 24" Dell 1920x 1200 to an AOC 34" Ultrawide 3440x 1440 I have an extremely frustrating issue... On a cold boot/start, when the video drivers kick in the monitor will go out of range and report "Input Not Support" I am able to remotely access the system. The display properties settings are correct. (3440x1440@60) I have to change the monitor frequency to 100 (also not supported) and back to 60Hz and TAA-Da perfect video If I do w warm restart everything works fine. However the moment I shutdown or cold boot I am back in the same place."Input Not Support" Please what am I missing / doing wrong.?
