Cannot calibrate display - error when creating white point
« on: June 18, 2018, 06:19:39 PM »

I suddenly cannot calibrate my NEC MultySync PA271W display any more.

Every time I try I get the error message that the white point cannot be established and then the software kicks out the old .icc profile and switches to a horror yellow uncalibrated profile.

I loaded the old profile in again so it now looks reasonable again, but I don't trust the calibration any  more.

Why can't Spectraview II achieve a white point any more on my display? Is my display burnt out, or is the i1Pro dead?

If you lower the backlight intensity say 10-20 cd/m2, any luck?

I tried 10 cd/m2 less at 120 cd/m2, and again get "Error: An error occurred while adjusting the white point."

Looks like my display is shot.

Actually I have the i1Display (not the i1Pro).

Yeah perhaps it is but usually the failure is hitting the cd/2. Reboot? See if software can be updated? What if you pick a different white point?

I am usually going for D65.

I tried after reboot, even at 110 cd/m2 it's a fail.

Too bad the PA272 they sold for 850$ last autumn is back up at 1250$. On top of it it's an old model from 2013

For now, I let the monitor go back to the last achieved calibration.

Do you have another display where you can test the instrument? Perhaps it's at fault?

I have a MacBook Pro - never tried to calibrate it. Can't use the Spectraview on it, so I'll have to see what software I can find to try to calibrate it and see what  it does.

But I think it's the display. Last time I got a Delta E of 11 at 130 cd/m2. I lowered the brightness to 120 cd/m2, and then I got an acceptable value, but still not good. That was six months ago. I guess once this starts, displays go quite quickly.

Again yeah, that deltaE report is way over the top. Still, I think it's worth testing the instrument before you toss the display. If should be able to download the X-rite software and run it on the Macbook. If it doesn't fail, then I'd be more inclined to agree it's the SpectraView.

Yes, I'm going to download the X-Rite software and give my MacBook Pro a try.

Maybe it's also because Spectraview II has a problem with High Sierra?

I use Spectraview II on High Sierra. No problems. It just got an update.
