So I have a dual display set up on my gaming laptop, the external display I’m using primarily is set to a 4k resolution but I find this makes the cores glitchy sounding and slow so I down the resolution to play to 1920x1080 and this is fine, but in windowed fullscreen I’m having to change resolutions manually, so I set the fullscreen to non windowed and set the height and width but doing this now means retroarch is only filling the screen by about two thirds from the top left corner, what else do I need to do to get this working so it fills the whole screen ?
I usually disable one monitor before launching Retroarch.
Hey there,
Cant you simply set your external monitor to 1920x1080? From the screenshot you posted it seems you set the desktop to 1440p and Retroarch in a borderless 1080p window.
