I like having mixed monitors. One is a 19" Viewsonic at 1280x1024, the other is a Samsung LCDTV at 1360*768. Thoroughly love it. I use the 19" for daily business but switch over to the 26" for gaming/movies and kicking back onto the couch or at least way back in the desk recliner. Saves on the life of each monitor. Sometimes good to use simultaneously.
