NEC PA242W Monitor Review
by Chris Heinonen on September 27, 2013 9:00 AM ESTUpdated 10/2/2013: Talking to NEC after this went live it was found that the review unit had a feature, Metamerism, enabled. This helps to match it to other displays, but also caused the pre-calibration numbers and non-SpectraView numbers, to be incorrect. I'm currently re-running the pre-calibration numbers on the NEC now and updating the pages as fast as possible. The end result is that the NEC performs far, far better out-of-the-box than initially thought.
Be prepared, as there is a lot of bench test data coming here. For my pre-calibration settings I used the sRGB color gamut, a color temperature of 6500K, and a gamma setting of 2.2.

Pre-Calibration (re-tested) |
Post-Calibration, 200 cd/m^2 |
Post-Calibration, 80 cd/m^2 |
|
| White Level (cd/m^2) | 197.0 | 204.14 | 80.79 |
| Black Level (cd/m^2) | 0.3457 | 0.366 | 0.1479 |
| Contrast Ratio | 570:1 | 558:1 | 546:1 |
| Gamma (Average) | 2.2633 | 2.1437 | 2.3734 |
| Color Temperature | 6460K | 6426K | 6442K |
| Grayscale dE2000 | 1.573 | 0.6504 | 0.6473 |
| Color Checker dE2000 | 1.0198 | 0.6392 | 0.5331 |
| Saturations dE2000 | 0.9682 | 0.6722 | 0.5675 |
Out of the box the NEC is practically perfect. The grayscale has a little bit of an error but one that should barely be visible if at all. The gamma has a small peak at 95% but no huge issues at all. The colors are reference quality and there is nothing to complain about with them. If this was a post-calibration result I would say it is amazing. The fact that it is a pre-calibration one makes it even that much more incredible.
Post calibration, aside from a dip in the gamma at 90-95%, everything else improves and becomes practically perfect. Yes, the overall error levels can be lower but you couldn't see it. None of the 96 samples in the large color checker chart even come close to a dE2000 of 2, much less the visible limit of 3. The average error of 0.63 is the lowest I've ever seen. It's perfect.
When targeting 80 cd/m^2 and the sRGB gamma target we see similar performance. The gamma curve isn’t perfect but really everything else is. The color checker chart hits an average dE2000 of 0.53 here which is even better, but not visible. What you see on the screen is what you are supposed to see.
With Metamerism turned off, the NEC measures perfectly. The only improvement I could see is in contrast ratio, but they might be letting that suffer to coax more reliable overall performance of the panel which is a trade-off that would be worth it for their target markets. Perhaps once OLED gets affordable we can see something better, but until then this is really, really good.

Wrong. It is perfectly acceptable.foxalopex - Monday, September 30, 2013 - link
Input lag? The monitor is rated for 27 ms which works out to 37 fps. Video is typically only shot at 25 or 29.97 fps. While a gamer might need more than this, video certainly isn't this fast.marqs - Monday, September 30, 2013 - link
Input lag consists of signal processing latency and pixel response time, of which only the latter limits the practical fps. By enabling overdrive the response time should improve by a couple of ms. Btw, I think the latency charts wrongly claim to be against an CRT, if the results are taken from averaging the results from Leo Bodnar lag tester (which results to ~7.5ms for a lagless CRT). The real input lag for PA242W should be around 20ms with default settings.cbelle - Monday, September 30, 2013 - link
720/60 is a standard used by many including ABC, ESPN and FOX in the US. So this is still could be an issue to video and music editors (video sync playback).Not horrendous but not great either. But if it can be lowered to 20ms that would be nice.
For video editing I think it still lacks 10 bit, SDI and video production specific needs. It is nice alternative for home editing but not sure in a suite or in the field.

When will Anandtech test Eizo displays and see whether the significant price gap is justified ? One area that is hardly if ever addressed in display reviews is the bit depth of the DAC circuits, and the resultant impact on signal aliasing (Mach banding) and the quality of gradients, the signal-to-noise ratio. Uniformity, linearity, brightness, contrast ratio, response time and gamut are not all there is to display technology. Speaking of contrast ratio, we need numbers, that are not biased by the absolute blackness of the display, since anything below 1% brightness will multiply the factor enormously for not huge perceptual gain. A linearity plot showing the length of the straight portion of the gamma-corrected display should help compare display performance. Look at what the folks at Digital Photography Review do to compare cameras.TheRealAnalogkid - Tuesday, October 1, 2013 - link
...and people look at me weird because I have a second Sony GDM-FW900 Monitor in the closet for after the one I'm using dies. I'll miss them when they're gone; maybe tech will make something comparable by then.Kathrine647 - Wednesday, October 2, 2013 - link

1920x1200 on a 24" is low resolution. 24" tend to be this resolution and you can see all the very large pixels. I would not recommend 24" screens for profesisonal use until manufacturers start increasing the resolution. 1440p would be perfect on this screen size.mrstonecold - Friday, October 4, 2013 - link
Does anybody now if this screen uses an active cooling element (fan) like the new eizo screens cx240 and the cg246. I'm in the market to replace my primary screen (dell u2410) and I prefer a quiet work environment. Thx.foxalopex - Friday, October 4, 2013 - link
The NEC-PA242W is absolutely silent, there is no fan. It doesn't even have a high pitched whine which is nice. The monitor is pretty thick partially for passive cooling I suspect as looking into the cooling vents at the top, you can see a massive airspace behind the actual panel hardware itself.
