We're not big gamers, but at Digital Downtown earlier this month we found out an interesting tidbit about projectors and video games. According to Panasonic's rep, most projectors suffer a small lag time with video games. This is backed by a forum we found where a member complains about a noticeable fraction of a second lag time while playing Guitar Hero 3 on a Toshiba projector.
To deal with the annoying lag, Panasonic developed a projector that eliminates the pause. Their PT-AX200U, out now and available at Amazon for $1,300.
The only issue is that the projector is only 720p HD friendly, but the 2,000 lumen light source makes it possible to get stellar image quality even during the day.
