My aim is to run Witcher 3 at 80% or 90% of 4K, and with HDR. Special K gives me a black screen unless a) GOG overlay is disabled and b)the game is in borderless full screen at native res. If I run at fullscreen with SpecialK, I get a black screen. I made a custom resolution in Nvidia Control Panel for 90% of 4K, however if I select it even with borderless fullscreen then SpecialK again gives me a black screen/frozen screen.
This behaviour seems to be consistent regardless of whether HDR is enabled, and HDR works fine at native res and borderless fullscreen.
So any ideas of how I can get a custom resolution to work with specialK in this game? Thanks!
Also, out of curiosity, why does Window Resolution 3840x2160 at the top of SpecialK have a 250% next to it?
You might want to give 3200x1800 a try. It is pretty close to 4K but doesn’t require you to make a custom resolution.
Otherwise, If you absolutely must use a custom resoltuion, use CRU to create one. It should work better then nvidias custom res solution, since CRU creates a new resolution inside your monitors EDID (well, in windows’ regedit anyway)
Thank you for your responses. Seems like I royally screwed something up because I deleted the Specialk documents folder, going back to default settings, and everything works just fine now. Sorry!
