[sorry for the lag, I'd left this in my drafts box after a few days of futzing with the setup] Hi Felix, Thanks for the suggestions, greatly appreciated and got me something that works. After lots of (literal) head-banging under my desk by swapping cables and outputs I've come up with a repeatable workaround: Power off the screen (front panel switch) Jump to virtual console one (Ctrl-Alt-F1) Power up the screen (starts at 2560x1440 @75Hz) Ctrl-Alt-F7 back to X and slide the resolution from 1920x1080 to 2560x1440 from Plasma & apply. About half the time Plasma/X wakes at 2560x1440 without needing to do this. 2560x1440 is only available on the Display Port connector, all other outputs were limited to 1920x1080. I've found with such a large monitor at hi-res that I can work effectively with just one screen, which has simplified things. I can't find any AOC firmware update and am on the lastest BIOS update. The above isn't ideal, but it works, everytime. Thanks, Daniel -- To unsubscribe, e-mail: opensuse-support+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-support+owner@opensuse.org
