NEC 2690Wuxi display luminance troubles

[GeraldB]

I've had my NEC 2690Wuxi for a couple of years and love it. Now that I've gotten a printer I need to start paying more attention calibration. The calibration device that came with the monitor is very easy to use. However I have problem that I've always ignored. I cannot get the intensity to reach a very modest target. The monitor is supposed to be capable of 400 cd/m2. The target for my profile is set is 90 but during calibration it only reaches 74.4 and has a terrible DeltaE. I've gone into the OSC advanced setting and turned off all the auto adjusts and set it so that the profile manages it. The measurements were taken using daylight into the room, no direct sun of course. I've attached a screen shot of the calibration output.
Any suggestions how to get the display luminance intensity up?

Here's a question -- did you remove the white cover from the puck? It looks for all the world like a single unit, but the white part separates. (I should know, it took me over an hour to figure this out when I first got my 2690....) The symptom is exactly what you describe -- very low luminance and terrible delta-E readings.

I keep the cover on because I'm sure I read that is correct for LCD monitors. You take it off for CRT monitors. Did you take it off on an LCD?

Dumb question, we're talking about 2690. I'll try taking it off.

Definitely remove it, that almost certainly explains not being able to hit even 70cd/m2. Otherwise I'd say either your monitor or puck is defective.

I removed it and all works perfectly! Thanks a ton for the guidance.

Glad you figured it out. I, too, did not know to take the white plastic cover off the puck. I'm sure it's in the instructions somewhere, but I sure don't remember finding it. They need to print it in big bold letters somewhere, or better yet, put a sticker on the puck that says "Remove this before calibrating monitor!"

I'm just glad to know I'm not the only person who made this mistake...
