Hello. I'm not sure what I did. I think I might have hit an Hotkey. I'm not sure. Anyways. I have an MSI GE66. Fully updated windows, fully updated drivers. The 15" screen (built in laptop monitor), it has a native 1920x1080 display setting. If I use that resolution the screen fills the whole monitor. When I try to use a different resolution, like 1366x768 (because I don't like the 1920x1080) the screen will be inside of a box in the center monitor. This affects gameplay which is very annoying. I don't think a 15" screen is big enough for 1920x1080. I prefer 1366x768 instead. Now it wants to a box in the center of the screen.
I've tried different guides but 1: I have no option to scale screen resolution, neither in Window's nor in Nvidia's Control Panels. 2. I have full admin so I don't understand why the option doesn't appear. So I've tried several guides but they don't help because those options don't appear.
Any help would be greatly appreciated.
