My brother went to the US this week and, using some US Best Buy gift cards from christmas, bought a Mitsubihi HC1500. I was at his house today and helped him set it up. I had a thread here before where my brother bought the new Optoma HD65 and we both saw rainbows (I saw more). He returned that.

Anyways, he paid $525+tax with the gift cards so he was willing to risk another DLP.

Anyways, he sees Rainbows once in a while, much less than he did on the HD65. His wife sees nothing. I on the other hand saw rainbows everywhere. From Gladiator to Blackhawk Down, Fantastic Four, you name it. We tried many movies, and I saw it everywhere. Completely unwatchable for me. Didn't matter if it was dark or light, it was apparent.

Now I need to find a manufacturer who makes a 7 speed wheel just to go and check out a demo for fun. Maybe I'll see rainbows on that too. Sigh! There goes watching movies at my brother's place! :mad:

I think you should be looking at LCD and LCOS (SXRD) instead. If they're bothering you that much on the HC1500, you're probably a hopeless case for DLP.

I already have a projector - the Epson 720. I'm not buying one. This was my brother's new projector. I'm a bit miffed that I won't be able to go to my brother's place and watch movies on his DLP. His wife likes it and so does he. It sucks when everyone comes to your place for sports, movies, and leaves a mess. I want to leave a mess somewhere too. :(

I want to leave a mess somewhere too.

Parties are always more fun at someone else's home. Especially the next day when it's cleanup time.

get him to return it and get the ax200. throw in a hundred bucks

I am too but not on the extreme side, I suffered more of eyes fatigue that
is the most turn-off for me.

I think you kind of get de-sensitized to them also.
I noticed a 'bit' of RBE on my H27 in the beginning, anytime I saw a starfield or when i was watching B&W flicks (think Casablanca/Sin City etc.). But honestly, after 2 weeks I didn't even notice.
One day I commented on it to my GF at the time, and she immediately started noticing them, but after a week, she said it was back to normal.
so feel free to go over and drink his beer.
:)
I think IF you can eventually get past it, you'll enjoy it.
Also a big factor was going from a 50" to a 92". I think my eyes were scanning too much and it was bringing out the RBE. Once i got used to it, my eyes relaxed a little, and it became a pleasure to watch.
just my $0.02

After 6 months with my HC 1500, I don't see rainbows at all anymore. In the beginning, after about 2 weeks, particularly when I was tired, I would see the dreaded rainbows, but after a while they went away. I don't know why?

You forgot to wear the welding helmet a couple of times during those six months? :D

Same thing here almost five years ago when we started big movie watching with an Infocus X1. I had trouble with RBE for a couple of weeks, then it stopped being an issue. Now I rarely ever see one. No eye fatigue either. My wife has never seen RBE.

I see them all the time with the projector I use in my class. I also see them on RPTVs, and every other DLP projector I've encountered. The sensitivity to it is variable from person to person but I sympathize with the OP. I use the PJ at school every week and even with static images I notice some rainbows--I often have a headache when I leave, particularly if we've screened part or all of a film. Once a week 30-40 weeks a year I can live with. Every day, not so much. Thankfully, LCD projectors are available (I have one) or I'd be out of luck (LCoS was not within my budget when I bought a projector, though it could be my next one).

Eye fatigue is almost always a sign that the image is way too bright. You have to turn down the brightness and the Brilliant Color on your PJ to stop fatigue. I had it happen with my high gain screen but it has never happened with my gray screen.

I noticed that disabling BrilliantColor and dialing brightness/contrast on my HC1500 also really reduced the amount of RBE compared to out-of-the-box settings. I still do see rainbows, but rarely is it enough to be bothersome/distracting.

Nope. But I have insane hand eye co-ordination and reaction times. I don't know if that's a factor.

Hmmm that begs the question ...Are rainbows worse on video games because your constantly looking at different parts of the screen?

I tend to see rainbows WAY MORE on movies. I rarely saw rainbows on games. But then again, my only gaming experience on DLP is NHL 08 for the PS3.

It has been found that mostly gamers are affected by rainbows in DLP pjs...at least that's what I read a few years back. I too am a gamer and am suceptible to RBE. When u observe urself playing video games, ur constantly looking for movement at the periphery of the screen. Eye movements are akin to REM during sleep, switching from center to different parts of the screen attempting to confirm movement not in tune with rendered environment. These eye movements are what causes the rainbows, snapshots at different angles with basically 2 cameras, ur eyes, giving ur brain different images to process. The color wheel basically projects different colored images so rainbows appear as ur eyes try to fuse 2 images. If u keep ur eyes in one specific point on the screen, u will notice a decrease in RBE if not total resolution of said phenomenon.
Oh BTW, I know what I'm talking about...am an ophthalmologist.

I'm kinda hungry for some good tooth-killing candy right about now. :o

Yea a $0.93 cent bag of LemonHeads from Walmart, and Hershey just released a new chocolate called Bliss thats pretty good. Oh and some Smarties.

I'm guessing age is a factor as well, since with age comes a reduction of hand eye co-ordination. No wonder those old fogies keep making those slow 4x color wheels. Speed em' up gramps! :cool:

Speed em' up gramps! :cool:The hand-eye coordination would help explain why your RBE symptoms are much more pronounced. You move your eyes more.

it's related to the speed of your eyes blinking. When you're tired your blinking speed happens to sync with the projector's flashing speed thus you see the rainbow.
