Gnrl_KittyNo issues with any resolutions on mine, most likely something to do with your video card or driver.
I am using a Nvidia 650 TI via HDMI on Windows 8.1 with the 344.11 driver
Windows and full screen games letterbox 1920x1440 and 2560x1440 but not 1920x1080, 2560x1080 or 3440x1440
CalenKennedyI'm running a 7950 with clean install of latest drivers... really weird. It skips from 2560x1080 to 3440x1440. I also have "Maintain Aspect Ratio" selected in Catalyst Control Center as well as 1:1 Ratio set in the OSD.
