Part of the reason I bought into DLP is the immunity from burn-in. Zero chance of that. No burn-in. Won't happen. I need that assurance because I use it as a giant PC display and leave it on for hours at a time.
Even if you don't play video games, burn-in can be an issue when watching programs in 4:3 format. Since the edges of the screen are blacked out for long periods of time, it is possible to "burn" the screen that way. Not likely, but possible.
Lip-sync issues may occur with any HDTV technology whenever you split the signal. The solution is to send both audio and video to the same place... either the TV or the receiver. HDMI is helpful in this regard since both signals travel down the same wire. Digitally, no less. Output quality is an improvement over component cables. I've seen both, and the all-digital HDMI connection is the winner.
I use the Panasonic S77 DVD player as my source which has a HDMI connection and Faroudja DCDi decompressor (like the expensive Denon players). At only 200 bucks, the S77 is a giant-killer of a player. It features an audio delay option to fix lip-sync issues. In the event you *insist* upon splitting the signal (which I do), the delay fixes it at the max 100ms setting. This will be my permanent player until Blu-Ray takes off.
I'm curious about bulb life and color wheel noises and will see how things develop over time. I have a 5-year in-home warranty which should give me some peace of mind. Bulb prices should plummet over the next couple of years now that HDTV is really taking off. I don't mind replacing bulbs (I'm a tube guy, remember?
). The upside is that the display will always look as good as it did from day one.
The "rainbow effect" is much improved over earlier DLP models. It is visible but only if you look rapidly from side to side and TRY HARD to notice it. Why anyone would do this instead of enjoying the incredible picture is a mystery to me.
BIG WOW on the Qualia 006/Wilson setup. That setup is well into the six figures for the speakers and display alone. I bet they have a killer source driving the system. You MUST spend some time with that... although it may ruin you permanently.
