DLP Rainbow Effect & Eye Strain?

[alphamajor]

I've had my 52" WD52631 Mitsubishi DLP set since Tuesday, and I have to say that I am unsure as to whether or not I should keep it or exchange it for something else. There are three really big issues for me; black level, rainbow effect and the subsequent result of eye strain.

Now the black level can be helped out by watching with some ambient lighting in the room. This I could probably live with, so it isn't a complete deal breaker.

The rainbow effect and eye strain I'm really unsure about. The rainbow effect is of course most noticable during high contrast scenes. As far as the eye strain, I'm not sure if it's related to the rainbow effect or if it's just because of the way the DLP sets operate in general, with a really fast spinning wheel flashing colors on the screen at a high rate. Or perhaps it's because the sets are just so bright to begin with?

So, has anyone first had issues with their DLP set when they first got them, but got better over time?

BTW, I have set up the set to be as neutral as possible and dropped the brightness down. It currently could not be any better unless I want to pay for an ISF guy to come.

The only other rear projection set I would consider would be a Sony SXRD, but there seem to be a lot of people haveing problems with green or yellow hazes developing. I also currently don't like Sony based on principle. As far as other technologies, the only one that would work for me would be LCD, but that's a much smaller screen for the price and they still have issues of their own.

Any comments/help/advice would be greatly appreciated. Thanks!

As I understand Rainbow effect can be impacted by the implementation of the technology.


You may want to try the samsung HL-S5679W. It doesn't have a color wheel at all, instead using 3 high intenisty LEDs. It supposedly eliminates the rainbow effect.

whle I can observe the RE, it doesn't adversly affect me like it does others. Wish that I could be of more help.

Rainbow effect drives me up the wall, so much so that I would never own a DLP display of any kind (or any other "wheel" technology.

Me too! If you see it, chances are you'll never get it to go away, you should go for some other display technology.

When I first installed Infocus 7205 I saw rainbows left and right and at first I did feel a bit off after watching a movie but now I dont even notice them anymore. Even if im looking for them its still hard to see. There are some scenes here and there in movies which I can still catch a glimpse of a rainbow but i definetly got over the rainbows within a couple months or watching a movie every other night or so. Infact it was probably much before that, I just hadnt noticed that I wasnt seeing them anymore until then.

I catch a glimpse of RBE on my Mitsubishi HD1000 once in a great while but it doesn't bother me in the least. I have never experienced RBE on any rear projection DLP display. Some people are much more sensetive than others.

LED and laser lit DLPs (coming from Mitsubishi this year) will eliminate RBE for good though.

I don't own a DLP but I have tried very hard to see rainbow effect on display models and I never do. If you do notice it there is a chance that you will get used to it and learn to ignore it as some have said already but if it were me, I'd take it back the first time I noticed because my stupid brain would *try* to see it again everytime I watched TV.

The JVC D-ILA sets have received very good reviews. http://www.hometheatermag.com/rearprojectiontvs/207rptvface/index.html

At this point I'm giving up. The Mitsubishi is going back. While my eyes were becoming slightly less strained, the rainbow effect is just way too distracting.

I was going to exchange for a Sharp LCD, but the red push those sets have is horrible. Even so, LCD displays just look really blocky to me. It's something about seeing the actual pixels. The rear projection sets just look better in my opinion.

Given that I cannot find a display technology out there that does not have some significant issue, I'm giving up on televisions for the time being. Here's to hoping for SED and laser DLP.

I'm not sure what has the significant issues you are referring to. LCoS (SXRD/DiLA) both have 1080p displays available and are often considered the best technology on the market today.

LCD rear projection typically is not considered as nice as DLP or LCoS, but tends to deliver good quality for a bit less cash.

Flat panels, such as plasma and LCD can also deliver very good quality...

But, of all the display technologies on the market right now, I would lean towards LCoS for rear projection above all others. If you have liked DLP, then there is no reason in the world that you should be be thrilled with LCoS.
