Hi Jinx!
DLP is a micro-display or project technology based on a chip similar to an LCD or LCoS, except that it's much more responsive. DLP chips are fast at changing colors so you're not going to be concerned about the refresh rates. Multi-chip DLP projector are some of the best projectors made. But they tend to be prohibitively expensive which is really too bad, I would think Texas Instruments would make out like a bandit if they reduced the price a bit.
What could be an issue with DLP is the 'rainbow' effect. In a nutshell, if you're watching a movie with fast moving objects and your eyes follow those objects across the screen, a certain segment of the population will see what's described as 'rainbows' on the screen. You may make yourself see it by looking at your screen and then flicking your eyes across the screen and back... did you see the rainbow?
The rainbow is the result of the color wheel that spins. Basically you're moving your eye in cadence with the wheel's spin and it will make the red, green and blue light from the wheel visible.
If you don't see the rainbow, no problem. If you do see it from time to time and it doesn't bother you, no harm done. Some people claim to get headaches from it.
Ironically your ability to 'see' or not see the rainbow is probably a matter of evolution. Our 'hunter' eyes are designed to see peripherally at certain speeds. As stone age hunters we evolved to see game run out the corner of our eyes. Dogs are very good at this, so good in fact many can’t help but chase. I have been known to chase the odd squirrel myself.
Some people are better adept at spotting a rabbit or deer make a break for it out our peripheral vision than others – they are more likely to see the rainbow in any DLP HDTV.
Those who can see the rainbow were probably the most effective hunters in the Stone Age. Those who can't... well... we're better suited for playing video games on HDTV.
