wow, so nothing really happened. Next time I'm going with Eizo again.

Ended up getting an Eizo cg2730. No issues.

That's good news for owners. Wish they could have told me back when.

Since I've never had this issue, I have to wonder if I should bother with the new firmware update???

This is the update: "The picture uniformity and low luminance stability are improved".

Does this fix the large Delta E problem?  Has any one actually applied this update and seen an improvement in their calibration results?

Yes it does - at least in case of 5 units that I tested.

I wouldn’t bother until it happens ;)

I've tried 3 different USB drives. All of them are recognized but both "Update Firmware" and "Import monitor settings" are ghosted.

PA271Q_R1302.pac is on the USB with nothing else on the drive. Unplugged everything else that was attached, including display feed.
  • Load PA271Q_R1302.pac onto usb drive
  • Turn off power to PA271Q
  • Plug in usb drive to the top SENS/MEM port #1
  • Turn on monitor
  • Menu automatically opens to USB Flash Drive / Function Selection, but Update Firmware is ghosted. Bottom of menu says, "USB Drive: Connected
  • ??
Any suggestions? It is recognizing the usb drive but not the firmware file. I am on a Mac. Do I have to do this from a pc? Should I try reset? Current firmware is R1.001A, Spectraview Engine 5.00

Czornyj should/will chime in; I had a similar issue in the past with the USB stick when he requested I copy some data for him. Seems the trick is inserting it into one of the ports in the display itself. If memory serves, it's on the right side, at the top, behind a rubber goodie protector???

Thanks Andrew, I think that is the one I'm using. It does recognize the USB drive; just not the firmware file that I put on there.

I've been turning off the monitor from the front. Going to try the little on/off switch on the left side in the back. If that doesn't work I will reformat a USB drive and try again.

If you're on Mac, I'd check if USB is FAT32 formatted.

Hi Marcin,
Yes, checked:

Retried a few other usb drives. Tried downloading the firmware again. No luck.

It just won't recognize the file, and I didn't change the name at all. Hard to tell from this image, but "Import monitor settings" and "Update firmware" are both ghosted out.

Tried exporting monitor settings and that worked, and the menu "import monitor settings" is no longer ghosted. So it has no problem reading files on the usb drive. There must be something wrong with the firmware file I have on there.

Here is a link to my monitor settings and the firmware file I've been trying to get the monitor to recognize:
https://www.dropbox.com/sh/icxhdj9gnfwaidh/AABfdx-g1ZudnHrIGVZLlnFxa?dl=0

Thank you for the responses. I will call NEC tomorrow when they open. My monitor dE's are borderline. Not as bad as some, but not near Andrew's. Screenshot below using Andrew's target settings.

Good news and bad news. After speaking with NEC, they ran some tests and determined the file needs to be extracted and copied onto the USB drive from a windows machine:

Testing here confirmed the pac file needs to be installed on the USB drive from a Windows PC. For whatever reason, and albeit FAT32 is universal there is something occurring to the file when moved/copied to the USB drive on a MAC.

I can't explain that, but after booting up an old pc, downloading the file and dumping it onto a USB drive, the monitor recognized the file. I successfully updated the firmware.

The bad news is results are no better.

That's unfortunate Dave. At least it is not terribly off.

I really wouldn’t worry about this.


The manual states:

Values under 3 are generally considered excellent for display calibration. Values above 3 will be highlighted in yellow or red and may indicate a problem with the display’s calibration.
The graph shows the displays actual measured grayscale color tracking using measurements taken while generating an ICC/ColorSync monitor profile of the display.
The horizontal axis shows the Delta E values for each measured point on the grayscale. The vertical axis shows the luminance for each of the measured points on the grayscale.

Now this note might be telling:

Note: Since the Delta E values are calculated based on the currently selected Target, if a Target using Intensity: Specific Level is being used, and the display was not able to actually achieve the Target’s specified Intensity value, then this will result in large Delta E values.

So, what's the specific level being asked for?

That's interesting, Andrew. NEC has been quite helpful in suggesting things to try, and the most recent was to lower my intensity to 110-120cd/m2 in order to see if that changes the dE values. They also reiterated that my readings are not too bad. I am going to continue trying their suggestions. If nothing else, the firmware update issue was solved.

130cd/m2, 300:1 contrast ratio (target black = 0.43):
