Fullscreen rendering not working

Scale: 1x
Scale Mode: Scale to Fit (Letterbox)
Scales: 1x only
Start in Fullscreen: Yes
Width: 640 px
Height: 480 px

As a result the scene is shrunk and is only in the top-left corner of the screen. I've tried the other settings for scaling too but they all pretty much do the same thing.

I think this is what I just posted about also. I don't think it's working, can someone weigh in on this
