wide gamut monitor calibration

[DanK]

I just installed my new NEQ PA271Q wide-gamut monitor.

I have not calibrated it yet because it comes with an impressive document showing the test results for the specific monitor (listing the serial number). The target and measured gamma curves are essentially indistinguishable. The target and measured color values are very close, with only two delta-E values greater than 0.5 and quite a number in the 0.2-0.3 range. Given this, what would I gain from calibration? I haven't used an uncalibrated monitor in years, but I doubt the cheaper monitor I just replaced was this accurate even after calibration.

BTW, for what it is worth, I bought a hood to block ambient light.

Thanks.

That was with the screen hooked up to the test equipment that the manufacturer was using. Unless you are using the same driver, operating system version and video card that the screen manufacturer was using, how do you know that your personal setup will give you identical results? Higher end computer screens will all ship with their bench test results (mine certainly did too).

In a real world situation, I would expect what you are seeing and what the manufacturer's test report show to be very close, but you still need to have it properly calibrated to the setting you will be working in your working environment, not just the test bench. This is really no different than a camera manufacturer running a test on the assembly line and you finding you have to change the focus adjustment for your camera.

When I set up my screen for the first time, it was much too bright for my work space. The colour response (profiling) needs to match whatever luminance level you are working under. That is not necessarily going to be identical to the manufacturer's test bench.

Thanks. I'll calibrate it and see what difference it makes. Easy enough to do. I'll use my X-Rite puck rather than spending the money for theirs.

With the more expensive wide gamut screens, the whole calibration and profiling process can be a lot different than for "normal" screens. My BenQ shipped with its own software (based on the xRite i1 software) and required a USB connection between the computer and screen so that the two can communicate during the process. The ColorMunki line was not supported but the i! and newer Spyder models were. BenQ does not have its own "puck".

The output is written into a LUT that resides on the screen, rather than on the computer when done this way.

I have no idea what shipped with your screen, so I'm not sure if any of this applies to you.

I think it does apply. NEC has its own puck, but you have to pay extra for it. From what I have read, the i1 will work fine, but to get the functionality you describe, one needs NEC's Spectraview software, for which they charge. You need that to gain control over the monitor's internal electronics, and hence 10-bit, rather than just adjusting the operation of the video card.

The software is about $100 US, which seems steep, but given how much I spent on the monitor, I can't see crippling it to save $100.

That NEC "puck" looks very familiar....

Indeed it does...
