See...i dont about other types of Monitors and TVs but if you dont use the native resolution of an LCD TV (native is highest resolution you monitor technically supports), then it will look horrible, especially in games if you lower your resolution, everything will be blurry, distorted, and overall bad looking, because the monitor has take the smaller resolution and stretch it to fit the screen meaning there will be more spaces between each pixel resulting in jagged lines and other ugly stuff. thats why when you buy a monitor, make sure you get a videocard thats able to play games on it on its maximum resolution otherwise, as a poster above said "it really will look like ass" Also...AA is what kills your card, I bet if you playing on full resolution you would have to turn AA completely off and you wont see a difference meaning you will get better performance.
