Skyrim Resoultion Render Error?

[aja2788]

I have seen this post here and there but no fix. Does anyone know how to fix this issue? I keep getting a rendering issue and that my resolution is not supported, I am trying to play on 2 monitors both at 1920x1080. I have gone into the preference file and changed the resolution to 3840x1080 but it wont work, it was working for a little bit but every time now I get the resolution error. Any help is much appreciated!
