Custom Resolution Utility (CRU)

[sinsforeal]

Hello everyone. I have a QN700b 55' 8k Samsung tv that I am using as my primary display. So I am in a bit of a unique situation as I don't think this is a very common setup and I have not been able to find a solution for the problem I have been having. For some reason in the Nvidia control panel the "customize resolution button" is greyed out so I cannot try to add new resolutions. With the program CRU when I tried adding resolutions they do not appear in Nvidia control panel. Even upon inspecting with regedit in ->Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\​Configuration editing the values here had no affect. Can someone please advise me on possible remedies for this? My main goal is to create a custom resolution of 7680x2610 so it would be selectable in various games, with this resolution I can have an ultrawide display with games running on it and two small windows at the top for productivity while gaming.
