I am thinking about building a bartop system for my daughter and want to use an LCD screen for a mix of vertical and horizontal games. I was thinking for this purpose wouldn't a square (truly 1x1 ratio) LCD monitor actually be the best way? Then both horizontal and vertical games would be the same size on the screen. But does such a thing even exist? If not, is it at least still possible to get 4:3 screens?
I don't know how It would work doing widescreen LCDs. That seems like a waste of space/ratio because nothing would ever be full width or height.
