The CV64 and PIV really start losing performance above a 1024x768x16 screenmode. Unfortunately, that leaves only 15" panels. Eizo made some outstanding 15" LCDs, while no longer produced it might be worth searching for one. Another benefit is they handle 50Hz just fine via VGA, and you can adjust them for perfect PAL displays (games) with the image covering about 80% or so of the screen area. Ultimately, you trade screen size for overall quality.
