Question for folks who use a retrotink 5x w/ a 1080p monitor: Do you use the 1080p under, over, or scaled mode? To summarize, under is a true 4x (doesn't fill the vertical height of the screen), over is a 5x and discards the overscan areas on the top/bottom of the screen, and fill scales the image/does some nearest neighbor scaling to fit the vertical height of the screen.
I'm mostly curious if anyone uses 1080p over and if any important visual queues or information is lost to overscan.
