just bought new benq e2200hd full hd 1080p monitor for rm710 yesterday  .
it's really worth to buy for ps3. it got 1 HDMI port and also built in speaker too.
i thought there is no built in speaker, but after i plug in the HDMI cable i can hear a sound from the monitor when i click at my ps3 controller.
maybe the sound from the monitor speaker not so good but it's ok for me because i got another external speaker which i can use 
one more thing i can just plug in my external speaker without using any rca 3.5 mm and rca female to female adapter because this monitor got audio in and headphone jack input signal too, so this monitor is very good compare to other lcd monitor which need the rca 3.5 mm adapter and rca female to female adapter in order to get the sound 
the graphic is much much much nicer than my lcd tv 
if u r looking for full hd monitor for ur ps3 then i recommended this monitor for u           

I've tried playing GTA in 720p, 1080i and 1080p the graphics are jaggy in all.
