Hello, I currently have a Asus (VH236H) 23" 1080p 2ms monitor which I use for my ps3, I realized most of the console games are native 720p and they get upscaled when playing in a 1080p display. When I play Uncharted 2, I notice some zigzag lines around many things specially leaf or grasses. My question is if I get a 19" only 720p supported monitor, will the picture quality look better because there wont be upscaling or due to the smaller display?
The answer is "maybe". It all depends on the game and the display. Some do a better job of scaling to different resoutions than others. The jagged lines could be coming from a lack of anti-aliasing as well as upconvertion. I would not recommend you spend money on a different monitor to test things unless you have enough that a failed test won't hurt you.
