Ok, so give it to me in english doc... So the dlp tv that has the highest refresh rate will have least lag right? So which brand do u recommend?
No, that's not at all what I said.
What I said was that ANY TV with fast processing, which has nothing to do with refresh rate, will take the input you feed it and get it up on screen fastest.
I'll try an analogy:
A car that goes 150mph is not what you need. What you need is a car that goes from 0-60 fastest. When you look at refresh rate of the display, you are looking at the top end speed, but you are ignoring accelleration. What you need to focus on is the accelleration of the vehicle. How quickly can it get going from zero to 60. A 240hz display could have a 50ms processing delay, while a 60hz display could have a 7ms delay.
ALL digital displays have a delay, so the question is 'How long is that delay?'
I am not a gamer so I don't have any specific recommendations, but I would check a few gaming specific forums for some recommendations on this. My main focus is front projection, not rear, so I don't know as much about the rear projection DLP models. I would read some specs on different models and see if they have a delay time published.
