Those are the raw waveforms for X and Y, and when not in XY mode you are plotting their amplitude versus time. Go back to the settings that gave you the small square, and change only the two knobs on the left to a smaller volts per division (a few stops clockwise) and that should make your small square into a bigger square.
Viewing the raw waveforms can tell you if the board is putting out appropriate signals (and yours are in the ballpark), but for the issue you describe it would be difficult to use them to verify the board is generating a perfect image. The goal here is to use the scope as a known-good vector monitor, and see if the issue persists (e.g., is a game board issue) or if the image is fine (e.g., is an issue with your monitor).
Success!
It looks the same as it does on my other display. Now I assume I should try to adjust the XY pots on the game board or is it enough proof that it looks the same on this display?
