Right now I have a 42" non-DLP rear projection HDTV by Samsung. Gaming is the main focus on my HDTV. I have all three consoles, and an Xbox 360 on order. About 75% of the time I use it is on games, with movies being around 20% and regular TV a distant 5%. Since most games have a HUD on screen 90% of the time, burn in is a constant worry of mine. I've had the HDTV for 2 years and no hint of burn in (it was a Costco floor model, so it's probably even older than that), but I'm starting to look at the very nice picture on the newer units. Mine only does 460p and 1080i, and doesn't support 720p so I'm starting to look for a TV that will support the higher resolution of the newer consoles. I do not want plasma, and LCDs are still too expensive for me, so looks like I'll be getting a DLP unit. I'm hearing about rainbow effects and gaming lag, though. I'm not effected by rainbows, but lag is a concern of mine. Can anyone at least give me an idea on which sets to look at? Looking for one around 46" - 50".
