k none of those viewsonics tehdigit recommended.
The vx922 plays videos and dvds poorly
and the Vx924 has a backlight leak, so clearly that isnt good
if you want a viewsonic go with teh VP930B, if u feel uncomfortable about it, check it out at Tomshardware, its a GREAT monitor for its price.
and if u can afford it, go with the LG L2000C, its like one of the best monitors ever.
