Talk:Downsampling – A full guide to achieve 3840x2160 resolution – NVIDIA only/@comment-97.80.156.255-20150107222536

I have a dual monitor setup, I can create the custom resolutions and test them on my external screen (set to default screen with my laptop screen off) but once I engage the chosen custom resolution on my external screen in game everything switches back to my laptop screen and turns my external monitor off.

My external is 1366x768 (720p) and my laptop is 1080p, if that's necessary.

Anyone know how to fix this?
