Better response time, but a lot of tv's like my Sony Bravia have a gaming mode that disables the post processing which greatly reduces input lag. I like playing on my HDTV, but I still have a monitor if I want to play in 3d and whatnot.
I've been looking at some monitors and was a little disappointed at what I saw. How come most monitors only have one DVI and why aren't these monitors using HDMI as the main connection ? I would have thought by now most of these monitors would also have HDMI ports. I can use the DVI for my PC but what about my PS3 and possibly a PS4 down the road. This is definitely a deal breaker for me. My Samsung tv is good tv I'll just have to get proper desk for it.
