I have a new Dell XPS 15 with a native 3200x1800 resolution. I'm trying to scale it down to 2560x1440 but windows doesn't give me that option by default. I have to go all the way down to 2048x1152 to keep the same aspect ratio. So I used the custommodeapp.exe to set a custom resolution but I get "The custom resolution exceeds the maximum bandwidth capacity" error using 60hz. I tried 59, 40, 32, and 30 aswell without luck. I read other threads about this but they were for external monitors. This is for my actual laptop screen which should work considering it's under the native resolution. Any ideas?
