I use a 24" 16:10 Benq TN Panel for my PS3, both for games and Blu-Rays.

For a TN Panel, the colours are pretty decent, especially compared to the 22" Acer and my notebook screen, no match for the iPhone 4's IPS though.

The problem with it being 16:10 is that it needs to be able to crop pictures to 16:9 itself, a PC can do it all by itself, a PS3 or Blu-Ray player will just send the 16:9 image and let the monitor/TV handle the rest, which shouldn't be a problem if you get a 16:9 screen in the first place, just saw some 16:10 screens back then which failed to do this properly.

24p playback, I notice slight stuttering during slow pans in movies and sometimes during other scenes as well, since there is no way to put the 24 pictures a second of the Blu-Ray into the 60 a second of the monitor without repeating an image here and there. I blame Hollywood for using such an unusual picture rate for their movies, doesn't usually bother me though and can be problematic with TVs as well.

I think Tellos covered the rest pretty well.
