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.

Actually the whole 1080p labeling is for the HDTV industry and makes no complete sense to use in the PC space and 1080p(1920x1200) is 16 megapixels with 16:10 wide(Camera dependant).bobbozzo - Friday, September 27, 2013 - link
I have the Dell u2412M... I like that it's 16:10 (versus my 16:9 Samsung (below)); on 16:9 I don't feel like there's room for the taskbar...Anandtech reviewed the 2412:

At home I have a 23" Samsung 2343bwx which is 2048x1180, but its TN panel has serious problems for me when doing design or photo work; the viewing angle affects colors so much that a solid color looks significantly different at top or bottom of the screen versus the middle. If I move my head, it changes, so it's not a uniformity problem; just viewing angle. I sit over arm's length away, so it'd be even worse closer up.

2412 is only sRGB, not wide gamut like the 2408, U2410 and U2413.I agree on anything wider than 16:10 being too wide. 16:10 IMO is the perfect size this side of dynamically-sized holograms.

This monitor is designed for graphic designers and digital photographers and they don't need and don't want high contrast. The goal is what you see on screen is what you get in prints. That means what's on the display must be as close to what's on a print as possible. In a standard viewing condition (standard light, natural daylight white), matte paper prints have contrast ratio of about 1:200, luster paper has contrast ratio of about 1:250 to 1:300 and glossy paper has a contrast ratio of about 1:350 to 1:400. For that reason, if you have a high contrast monitor, what you see on screen will be different from what you get in print. You can't change contrast ratio of paper, the only thing you can do is to have a monitor that can be adjusted close to that. That's what professional grade monitors are for. Some of the very best (and most expensive) graphic monitors are made by Eizo, and their contrast ratios are in 1:250 to 1:400 range. One additional note, photographers often set their monitor light output to around 80cd/m2 to 120cd/m2 for the same reason, getting close to how prints look. If the display is brighter, you often end up with dark prints because if it looks OK on a to bright monitor, the prints will be too dark.WhitneyLand - Friday, September 27, 2013 - link
>>do you need this? If you’re asking that question then you probably don’t.Instead of this answer how about telling us things like:
1) Is it possible to see benefits without calibration tools?
2) Is it possible to see benefits in applications that don't manage color profiles?
3) If you grab a couple non color-pro friends and ask them if it looks better, what do they say?
cheinonen - Friday, September 27, 2013 - link
OK, I'll answer those quickly then:1) Yes, because the out-of-box experience is also very good and it is still more uniform than any other display tested to date. The calibration does not affect the uniformity.
2) Yes, and especially with calibration. The SpectraView software does all of its work inside the monitor LUT, leaving the video LUT alone. So color profiles or not, the image should be basically perfect.
3) I'd have to grab them and see, though I'll admit to mostly having friends who I've converted to really caring about color.

As a multi-monitor user #3 matters to me because it makes all my screens look the same. At work I've got 3 mismatched Dell screens (1901, 2208, 2210); and the fact that despite fiddling I can't get the colors on them to match is noticeable and a bit annoying. At home I have 3 NEC monitors (all bought refurbed to avoid breaking the bank) 2x 2090 and 1x 3090; out of the box colors between the three are close enough to each other that I've never felt the need to buy a colorimeter to calibrate them.inighthawki - Friday, September 27, 2013 - link
My experience has taught me to always go with the same monitors in multimon setups. 2x or 3x of the same brand, same model.DanNeely - Friday, September 27, 2013 - link
Even if I could've afforded multiple 30's at home I don't have the deskspace for them; and in any event I bought the 20's a year or two before the 30. (The 3way setup was however a major factor in why I bought what I did.)At work I got the screens one at a time; and had a pair of 2208's at one point; they matched each other about as poorly as the 2208 and 2210 do.

We have very similar setups. I have one 2490WUXi as my primary display and two 2090UXi as secondary display. All are first generation models which have the A-TW polarizer which greatly reduces the purple IPS glow on dark images when viewing at off angles. I also bought mine refurbished. NEC has excellent refurbs, and their warranty service is excellent as well. You'd have to pry my A-TW NEC displays from my cold dead hands! :)
