Vid, I was being sarcastic as well... \'you are so completely wrong\'...
Well, I use a 50 inch SONY monitor (we use it as a TV). Playing via composite, svideo and RGB, there is a big difference between the three.
RGB really \'cleans\' the picture up compared to svideo, and the colours are alot more defined and contrasted. The only downside to RGN is it makes aliasing worse in some games (and better in others) because its so clean and clear.
