NEC PA242W Monitor Review
by Chris Heinonen on September 27, 2013 9:00 AM ESTNEC offers their own calibration software, SpectraView, for their monitors. Most software packages like CalMAN work with the video card LUTs to improve calibration, and the monitor LUTs if they can access them. The NEC PA242W contains a 14-bit, 3D LUT that allows you to correct the output to be almost perfect. Using SpectraView, NEC will reset your video-card LUT to be neutral and rely only on the monitor LUT so it will work correctly afterwards on almost any PC.
You can use a wide variety of meters with SpectraView but I chose to use my i1Pro. It isn’t as good at low-light as the C6, but it's more color accurate. The C6 is accurate if you profile it, but the NEC software does not allow for this. Once connected you choose your targets (D65 white point, 2.2 gamma, 200 cd/m^2, and sRGB gamut here) and then the software calibrates the PA242W. The calibration is also much quicker than CalMAN, which is nice. You can save multiple different targets in the SpectraView software and then load them back up later if you need to work in multiple environments.
After the calibration I measured again with CalMAN using the same settings as before to see if this works better than CalMAN on its own. To see how this performs I had CalMAN measure far more points than usual, which takes a long time.
CalMAN Calibrated, 200 cd/m^2 |
SpectraView, 200 cd/m^2 |
|
White Level (cd/m^2) | 204.14 | 200.6 |
Black Level (cd/m^2) | 0.366 | 0.3827 |
Contrast Ratio | 558:1 | 524:1 |
Gamma (Average) | 2.1437 | 2.1596 |
Color Temperature | 6426K | 6458K |
Grayscale dE2000 | 0.6504 | 0.706 |
Color Checker dE2000 | 0.6392 | 0.8781 |
Saturations dE2000 | 0.6722 | 0.7461 |
The NEC software produces very similar results. The contrast level is a little worse, but the light output level is slightly more accurate. Everything else is close enough as to be a draw where this is concerned.
Average saturation and color checker dE2000 errors are below 0.9, which is incredibly impressive. No individual measurements rise over a dE2000 of 2.0, and that means you should have no visible errors now. None.
When I re-ran the NEC Calibration and targeted 80 cd/m^2 instead of 200, the results are not nearly as good. This might be due to using the i1Pro and it not performing as well in lower-light situations. It also might just be that the method the software uses is not as effective at lower light targets. With these I find the CalMAN calibration to perform better.
The SpectraView software also allows you to save your calibrations and recall them. You can select your saved settings from a drop-down list and it will reload the LUT into the monitor. If you're regularly moving from sRGB to AdobeRGB or other colorspaces and back, this makes it easy to do so. It also avoids using the video card to make it more reliable than other methods.
After using the SpectraView software and seeing what it can do, I’d suggest it should be considered possibly essential for this display. The ability to save and recall multiple presets makes working with the monitor with different media, or lighting conditions, simple and easy. There is no worrying about the display not being setup ideally for whatever environment you need to work in. Also worth noting is that by going directly to the monitor LUTs, the final calibrated colors will be used regardless of what program you run; this isn't always the case with video card LUTs, as games and videos will sometimes bypass those, and it's one more feature that sets a display like the PA242W apart from consumer models.

I guess this monitor is great for certain professionals. But for people like me that game and watch movies it really just stinks. Samsung makes an awesome 27" monitor with a bery nice contrast ratio with deep blacks and great detail I forget the model number but look for 27" 2560x1440 SamsungLaststop311 - Sunday, October 6, 2013 - link
I use a Dell u3014 because I found it on craigslist for 775 which i talked the guy down to 515foxalopex - Monday, October 7, 2013 - link
For most folks a ~$700 monitor will admittedly be more than enough for most uses. Some of us however really want a professional monitor for precision work.foxalopex - Monday, October 7, 2013 - link
It's actually pretty good for watching movies as well. The lag isn't as bad as you think. Though yes, this isn't for a high end gamer.
