I've been thinking about this for awhile, and just want to see if it's possible and if there would be any issues.
I built my cab almost 2 years ago and really like it, but in retrospect, I've regretted installing a 25" TV. The size is fine ( I can't imagine installing a 17" or even a 19" monitor, it would seem too small) but when playing Pinball or PC games, the resolution is disappointing. I'm running 800 x 600. I've tried higher, but there is no improvement with the TV.
What I've considered is mounting a 27" - 30" LCD sideways. This would give me the resolution I'm missing and would be better for the Pinball games with a portrait layout and some of the MAME games are vertically oriented too (PacMan, Donkey Kong, Galaga, 1942, and a few others). I know my current video card allows you to rotate the display but will I have a problem with the resolutions being out of synch? ie if it's 1280 x 768, can it support 768 x 1280?? Will it stretch games vertically or will it have black bars top & bottom?
Any downside to my imagination of a vertically mounted LCD?
