HELP: 2 LCDs show different colors!

Hi All,

First let me apologize for the long-winded post, I just want to give complete detail....

I have two NEC/Mitsubishi 1980sx LCD panels.
One I bought about a year ago and one I just got two weeks ago. The problem is that with _all_ settings exactly the same, they display different colors (or should I say color temperture?).

Basically the one year old monitor shows a warmer color while the new monitor has a bluer cast.
I've tried all the pre-set color temperture settings, ie, 5500K->9300K, and the 2 panels are just different.

I am driving these two monitors with a Matrox 750 dual DVI card so the signals are exactly the same. I've tried switching the two DVI connectors and the new monitor is still bluer.

One thing I can think of is that the one-year old monitor may not be as bright as the new panel since the pixels have been "burned" longer. But the problem with this theory is that 1) even thought it's one year old but I really don't use it that much, and 2) the difference between the panels is _not_ in brightness, but rather in color balance.

I've contact NEC customer support but the rep was not much help at all and he even got down right rude near the end so I am hoping some of the more knowledgeable people here can shed some light to this situation.

Any insight would be greatly appreciated.

Thanks

John

Hi,

Just to make sure I understand you correctly, are you asking whether I have tried switching the DVI inputs between the 2 displays? Yes I have done that. The content of the screens switched, but the "new" display is still bluer than the "old" one.
