What I am wondering is how much of a difference in quality a T.V. show will be versus the two. Right now I am using a 19inch monitor so either will be an upgrade. In the store the 24 compared to the 20 on an episode of Lost seemed to be different.
It also depends if LCD color shifting bothers you when viewing at an angle. I don't need a 24" and gaming will probably suffer from the higher native resolution (although my previous 20" display quickly grew too small for me..), but I can't stand the viewing angle on the 20". To me, the viewing angle and higher resolution is worth the money.
Someone convince me otherwise. I really want to open the one sitting on my desk, waiting to be returned.
