Its for married guys that only get to game a few hrs a week but buy stuff that the picture on movies get wifey approval all others look elsewhere.
I game 20 hrs a week min gaming to me is more important than watching the same 5 3d movies over and over
Why would it matter for sports? Still, it's pretty significant for gaming. I don't think I've lied to anyone, that's been what I've said all along.
For those that asked about lag significance, 60ms is playable with non-competitive games, but competitive FPS gaming (for example), where your response time is very critical, that would be a problem. 30ms is a reasonable number, but some really twitchy people could still notice. <10 is excellent. The 720p optoma DLP I used previously had no measurable lag (pretty much dead on with my 5ms monitor), so if gaming is your priority, gt750/hd66/pro350w/etc are really much better choices.
The way to measure lag is to get a monitor with extremely low display lag (the specs are published for monitors, a good one is <5ms), preferably with the same native resolution as the projector. Connect both and put windows in 'duplicate these displays' mode. Then start a lag test screen like this one:http://tft.vanity.dk/inputlag.html
Then get a camera with a fast shutter speed , start the timer, and take a pic. The fast monitor will probably have a bit of a lead on the projector, so you'll see the 'clock' ahead on the monitor than on the projector. The difference in times is the difference in display lag between the two displays.
