I've been using a Dell 15" E153 terminal on my DOS/WIN31/WIN95/WIN98/XP machines for about 7 or 8 years and have never had presentation problem, be it games, word processing, spread sheets or what ever. The LCD is 12.25w x 9.25h (15 diagonal) . I will concede that the larger wide format LCD's, 22" and up, will tend to get on one's nerves a little while playing with DOS.
