I'm looking at the 191T/192T and the PX191. $100 difference in price and the Planar seems to be the better of the 2, but at a cost. Other than the mount, what is the difference between the 191 and 192? I do some gaming, but not that much, but I do scroll web pages and ghosting/trailing images/text would be a problem. Half the reviews for the Samsungs say ghosting is a problem the other half say it's not or at least very little. I assume it is some kind of issue with the video card and the monitor, but don't know what. Any input on why a card would cause ghosting (using recent cards)?
