If this does not fix it, try plugging in your laptop/computer into a secondary monitor, then use the AMD/NVIDIA instructions depending on which discrete GPU you have. If you get an error ‘This resolution exceeds the maximum bandwidth capacity’, try updating your display drivers.Open General Settings and select your new custom resolution in the Resolution menu.Set Width to new width in pixels and Height to new height in pixels.Right-click desktop -> Graphics Properties -> Display.
