Sony SDM-HS95P(b)
great monitor (for gaming also), but even this model by all test with the best graphic display, isn't even close to my old Viewsonic P95f. It is funny, you can't see big difference in gaming or movies, but when you open PS and start to work on pictures, you can see BIG difference...
I'm big fan of ViewSonic, so I first got VP191b, with 8ms "response time"... Actually this monitor have full response time around 22ms... Plus I was been very dissapointed with his display as well, so I got Sony. Of course if you are used on Acer, BenQ or LG, my reasons for dissapointment will be funny for you...
Don't trust in marketing response time, read tests or if you can test it by yourself... Response time is only one of things, look at contrast rate, and DVI!
