One thing that I haven't seen much discussion on is the blue tinge of this projector. The stated color temperature is 8500K which would account for this. I plan to use a scaler rather than a HTPC. Is there any way to correct for this problem, or is everyone just ignoring this?

- what blue tinge?

- is that with or without the clear section of the color wheel turned on?

- where did you get the number 8500 from?

The whites just seemed to tend toward blue a little. This was apparent when compared to a Davis DLP on the same dvd scene. The Davis seemed to have slightly warmer, more natural colors. My dealer said the white segment was off. Perhaps it wasn't set up properly as they had only set it up a few hours before I viewed it. After I left they tried it with a HTPC and managed to adjust the blue level to reasonable levels. Perhaps it was only this unit that had the problem.


The 8500K comes from the NEC brochure which is viewable at their website.

The blue tint you noticed is a pure calibration issue. Set up properly the LT150 has some of the best colors I've ever seen.

Can the LT150 be calibrated? I've scoured the docs., but it only appears to have "front panel" controls (brightness, contrast, etc.).


Is there anything deeper that we can get in trouble with?

Milori,


There's the gamma presets and white segment of course. In addition the usual with screen vs. ambient light. Those are the usual ones I'd try first as those seem to work quite well. If not there's individual color adjustments in the form of brightness and contrast for each color. And tint/color temperature iirc. I'm at work right now so I don't exactly have it right in front of me.

The LT150 has a separate colour temperature control - I have played with this and always left it at default for best results. Blue tinge?? I am not seeing this. With the colour temperature you can gradually give the image a blue tinge or red tinge if you so desire. To the right for bluish image and to the left for a redish image - simply not an issue at the default setting (page E-37 of the manual).


This projector has a myriad of settings - begs the question doesn't it? Why don't people know this! You can download the manual from NEC's website.


I second Frode's comments and also Projector Central's - some of the best colour from a DLP yet!


Cheers,


Grant

Thanks for the reassurance on the color issue. I placed an order with Dell at the $2,118 price a couple of days ago and look forward to it's arrival. The next step is to obtain a scaler for the unit.

Actually you have the ability to adujst the Cuts and Gains for R, G, and B. Set the color temp to the middle then go to this screen. Get an optical analyzer and tweek it right.

Grant,


Where did you see mention of the LT150's color on Projector

Central's site? I just looked around the site (mainly in

the "reviews") but wasn't able to find it.


Thanks,


Bob

Thanks, frode. That's a mightly glowing review. If that's actually what I'm going to see when mine arrives I'll be a happy (and frugal) camper for sure.
