Hey [H], for some reason I cannot set my resolution higher than 1920x1080. I had it set to 3840 x 2160 previously but for some reason it is now set to 1920x1080 and that shows as being the highest. I am running a 1080Ti with the latest drivers and a Sony X900-F (4K TV). Under both Display Settings and Nvidia Control Panel 1920x1080 shows as the max resolution. Got me, thanks for any help.
