HI,
I have an Infocus X3 and an ATI XT800 Grafics Card and I have the red pixel issue, too. This has been going on for quite some time, like 12 month or longer.
Not sure what causes it. I tried to isolate the issue, the picture shows fine on the LCD monitor, but the projector has the red pixel issue. It appears that a certain shade of some dark color get translated into these false red pixels instead and causes these red outlines or interpersed areas with red pixels

. Reboot mostly does not solve the issue, and it is not related to running the projector for a long time or using a certain source (dvd, divx, mepg, ...)
Any idea?
