Kinda Off topic, but I cannot create a new topic and google searches usually lead me down to threads like this one or questions about problems with black borders, I actually WANT black borders.
So my question is:
I do not like how blown up low resolution retro games look in fullscreen on my 1440p computer screen. Is there a way to go full screen but simply have the picture be a small image in the middle of the screen that is maybe only blown up 2x or perhaps 3x with black around the edges?
Alternatively, if there is not way to do this, is there a way on Windows 10 to have only the focused window visible, the background being black and there being a ‘panic button’ (i.e. windows key) to select other apps?
I understand there are other solutions (buy a CRT, render at a high resolution etc.), but for now I would just like to do this simple thing.
