i was able to set the display at 2560x1600 (what I have always used with the monitor), but with my new workstation it is unusable (fuzzy and pixelated).
i have a 30" mac dvi monitor, a radeon rx480, and had to hook them together with a amphenol adaptor (it is what we had in the adaptors drawer)...
i assume that i need a better adaptor, but i do not know that for sure, and do not know which adaptor will resolve the issue.
any help is appreciated. thanks!
