TFT Cocktail view from below

[leiski]

Hi

I'm hoping to build a cocktail / coffee table games machine using a TFT monitor. I know there has been a lot of discussion here on the problems with viewing angles with TFTs but I have found the one I've been testing to be surprisingly good. Well to be precise it's good from above, and the left and right sides but not from below (looking from underneath). This means it should be fine for vertical (portrait) games but not good for horizontal (landscape) games. I'm running an emulator from DOS using a old laptop I had lying around (It's not fast enough for Mame). I wondered if anyone could help me with either of these solutions to the problem!!:

1) A way of reversing the viewing angles on the screen. I've heard there's a poloriser in front of a TFT, can it be reversed?

2) A Dos hack that flips the screen by 180 degrees.

Any help would be greatfully received!
