Color Consistency

Now for color consistency, we take our best calibration profile from the very center at 200 nits and test color accuracy at 9 different places around the LCD display in an evenly distributed grid. We’ve shown before that calibration is actually very localized across the display, partly due to the brightness not being uniform, partly due to the discrete nature of the LCD panel itself.

LCD Color Uniformity

If you go back and compare to the other 30-inchers, you'll discover that the PA301w is narrowly edges out the HP ZR30w and has a clear advantage over the Dell U3011. Interestingly enough, the PA301w has a uniformity setting inside the OSD which defaults to 5 (maximum) and seems to definitely improve overall brightness uniformity and Delta-E consistency. Whatever secret sauce NEC has apparently works.

    Whoooooooaaaaaa! Nice to hear the real truth about hospital medical costs thanks for the skinny!

    I take care of small clinics around my area. It's jaw dropping what medical equipment/software companies charge for their products/services. In the end it's the insurance companies that pay... and we pay them.

    Any small "niche" market that's willing to pay the cost gets raked across the coals with costs, particularly if the payer is simply passing the cost on to someone else.

    On the other hand, selling a product to 1 vs. 10 vs. 100 vs 1000 vs etc customers gets cheaper per unit.

    I've worked on programs where we had 1 customer. The total bill was rather astronomical to the customer. But that 1 customer had to pay salaries for 40 people, plus all equipment costs plus overhead rates for building costs, power, electricity, etc. I've also worked on programs where we had about 10,000 customers. The total cost of the program was about 10 times higher. But the cost per customer was about 10 times less. Economies of scale will matter.

    In this case, the cost of the hardware is relatively insignificant - I'm more than happy to pay 2000+ dollars for something that I will use on a daily basis for my livelihood, particularly if it saves me "12 minutes" per day over something that costs about $1000. If I work for a full year, those 12 minutes per day average out to about 52 hours a year. You have to earn "only" about $19.25 dollars per hour to make that cost up in just one year. For the jobs that would use something like this, $19.25/hr is paltry, particularly when you factor in the actual cost for that one person to do work (building rental rates, electricity rates, support staff, etc).

    Now, for my home use, you just have to figure out what your time is worth to you. If your time isn't worth anything, then you should clearly never actually have any free time. Otherwise, you're wasting time away.

    I think you mean PACS. I'm not sure what PAX would stand for.
  • Griswold - Wednesday, March 2, 2011 - link

    He obviously meant POX!

    No actually, I didn't mean PACS.

    When I said PAX, I meant PAX. Our hospital uses ImPAX from AGFA for reading films on radiology workstations:

    The Eizo monitors and Dell workstations costs just a little fraction of the licensing cost of installing ImPAX on these stations.

    First off, very happy to see that you're starting to include the high end displays in your review comparisons, thank you very much. My main two questions come as a general NEC user. First, it's not entirely clear exactly where the PA301w fits in to NEC Display's lineup. While it appears to be a straight up successor to the LCD3090WQXI that 90 series is still for sale as new on NEC's site (at a list price difference of just $100). Comparison makes it appear the PA301w has everything the 3090 did with some added tweaks and updated tech, such as slightly improved gamut and enhanced 14-bit lookup table, but it would have been clearer if NEC simply had retired to the old screen or made it a last-gen reduced price model or whatever. As it is, having zero reference to the previous flagship is a bit odd.

    Second, while you mention the hardware calibrator you're using I don't see any reference to the software, which can matter just as much. NEC's own SpectraView II software for example can talk to their screens via DDC/CI and directly adjust the internal LUTs as well as all other screen settings, which is not something I'm sure that 3rd party software can do (I know at least a few brands can't but I've never exhaustively checked the rest). Given how much you talk about doing manual adjustments I was curious whether you found that necessary even with SVII or if you were using some other solution like X-Rite's software.

    the software he used was coloreyes display pro, he didn't use spectraview ii at all. the fact that he mentioned having to adjust things manually means that coloreyes doesn't support internal adjustments to the monitor.

    the spectraview ii (or spectraview profiler in europe) software does all of the adjustments automatically, requiring no manual button pushing on the part of the user at all. in fact, if you then make manual changes to the monitor after calibration, the software warns you that the calibration has been tampered with. (you probably knew this already, i'm just stating this for the benefit of users here who don't know much about high end nec monitors.)

    brian, please update the article with information about the spectraview software and its ability to internally calibrate the monitor lut and store the calibrations into the monitor itself. this is one of the monitor's raisons d'etre. not mentioning it is like writing a review of a ferrari 458 and omitting that it can go fast.

    $2300? I just picked up a ZR30W for $1200. Pricewise, these aren't even in the same league. Also, not sure of the input lag on the NEC, but lag on the ZR30W is much less than the Dell due to the lack of an OSD. I'll take that any day....you can do most anything an OSD can do through the control panel or Windows anyway.
  • eaw999 - Wednesday, March 2, 2011 - link

    input lag on high end nec's (90 series, pa series) tend to average around 30-40ms. these monitors aren't intended for gaming so input lag wasn't a priority when they were designed.

    these monitors have phenomenal scalers, if you care about that sort of thing. not only can you choose from 'full', 'aspect', and '1:1', but you can choose to stretch the picture any which way you want, like on a crt.

    again, if you just want to play games, buy a cheaper 30" and spend the remainder on video cards and cpu's.
