On Screen Display

Before we dive into the actual display performance numbers, it makes sense to talk about NEC's OSD and a little bit about the in-monitor calibration option that's offered. 

Tapping the menu button brings up the OSD, but also enables some on-screen button labels that change accordingly as you move around inside. Rotate into portrait, and obviously buttons change - so too do the on-screen labels, which is awesome.

There are actually two sets of OSDs on the PA301w. The first is what you get when you hit menu, and is a nice (yet still comprehensive) skinned menu with pretty straightforward navigation. Settings for brightness, black, and eco mode are on the first tab, position and scaling are on the second, then color, tools, menu options, more eco settings, and finally the info tab. The second is the Advanced OSD I'll show in a moment.

What's awesome about the settings is that everything has units where possible - brightness can be changed from 40 to 400 nits, black levels can also be artificially increased to match an adjacent display. As I'll show in a second, after you've run the in-monitor calibration, if you select a specific number, it'll actually drive the display relatively close to where it should be. What a breath of fresh air compared to completely arbitrary percentages. 

Aspect ratio scaling options include full, aspect-correct, off (1:1), and custom, which is controlled from the advanced OSD. Inside the "RGB" tab are some basic color settings such as white point and simple color controls. Tools has PIP control if you want to use it, the USB port per video input mapping controls, some selection criteria for choosing video inputs, and off timer plus signaling. Menu tools is just OSD settings like position, color, and language. 

Inside "ECO" is some interesting stuff. Based on the configured price per kilowatt-hour, you can see the total electrical cost of using the monitor. In addition, based on the configured kg (of carbon) per kilowatt-hour, you can see how much carbon you've released indirectly. One field is for how much would've been used if you didn't have eco settings turned on, the other is how much you actually used. Both essentially enable some dynamic brightness based on ambient lighting measured on the front sensor - mode 1 corresponds to 200 nits of range, mode 2 corresponds to 100 nits. 

What about that "advanced OSD?" Well, you can get to it two ways. Under the color tab, at the bottom, is a link named "Advanced Settings." Pressing select on that will bring you there, or you can get there by turning on the monitor by holding power and input at the same time. Doing so then makes the menu button consistently bring up the advanced OSD for the duration of the power-on session. 

Inside are essentially the same options as the basic OSD, with more depth in the color/picture section and a few other places. White point and color tristimulus values are given in x and y, there's gamma control, and a new uniformity pane. If you're serious about getting color right, these are seriously useful. Initially however, things aren't that close to reality. Even though the white point is set at 6500K, we can see that measured value out of box is around 5600K. The color tristimulus points are also similarly completely wrong. 

This is where the in-monitor calibration is super handy, as it internally calibrates the monitor so these settings actually reflect reality instead of remain shifted by however much the monitor has drifted or differs from ideal. Initially, I spent lots of time tweaking the display color points in HCFR, shifting appropriately based on how much the numbers differed from measured. While that actually did yield better results, running the built-in calibration routine got me 90% of the way there in 1 minute instead of 1 hour like I'm used to doing manually. 

Internal calibration mode only works with x-rite i1D2 colorimeters. NEC has a rebranded version they sell in a bundle, or you can buy your own. Chances are if you're willing to spend $2k+ on an LCD, you're also willing to spend the $200 to get an i1D2. Again, it plugs into the right-side USB port. To get into calibration mode, either find stand-alone calibration in tab B of the menu, or press the left and right keys at the same time from the no signal screen. The display will initialize the sensor, then tell you to wait 30 minutes for the CCFL to settle - welcome to how long calibrating CCFL backlit displays usually takes in-between adjustments. 

After that, you can select "self" for self calibration, or "copy" mode to actually match another PA301w or another display entirely. The display will prompt you to stick the colorimeter in the center, then run through its tests. The actual set of tests seems very basic - red, green, blue, then a whitepoint and brightness test. It takes almost exactly one minute to run, then tells you it's all done. 

The results are awesome. After running through, the white point is much closer to the actual reported value, and the primary color tristimulus values are much closer to what they should be. Note below how the brightness value and color temperature value are now much closer than they were pre-calibration. 

The even better part is that the presets also now correctly work for mapping to different color spaces. If you try to use them without calibration, you risk being offset depending on how the monitor has drifted. I still ended up tweaking all six of the x y values for red green and blue, but they were much, much closer than before.

    When i saw the title, i thought, wow, this must be a really bad monitor.
    After reading the review, it looks like it is THE BEST with except of weight and dimensions.

    Could you please change title, its misleading.

    It's an American coloquialism instantly recognized by most who lived there whole lives here.

    That said, there is a lot of word play in journalism I don't get and is a little frustrating when it happens to me so I understand your point.

    Ever heard of "The Baddest Man of the Planet"?

    This is a very normal way to put it. Nothing wrong with the title.

    CCFL Backlight
    165 watts (typical)
    41.5 lbs (18.8 kg)
    2560 x 1600 at 60 Hz

    Might as well just get a 21" CRT with those specs and price ...

    I am sitting in front of a 21" CRT that I am still reluctant to pass on (Sony GDM F520) and those weigh around 35 kg / 77 lbs. It can only do 2048x max. Reply

    We had this discussion on one of the previous 30" monitor reviews. While LEDs backlights are lower power than CCFLs and have won most of the mobile market, and while LEDs can surpass the gamut and color accuracy of midrange CCFLs at an acceptable price premium and are winning the consumer display market, the best RGB LED backlights still cannot beat the gamut and color accuracy of the best CCFL backlights. Until that happens (or until consumer demand becomes large enough to sell a less capable low power model) displays aimed directly at the professional market will continue to use CCFL backlighting despite the higher power consumption.

    The final point I'd make is that the "typical" power consumption NEC lists is a worst case number. Depending on brightnesss Brian measured 58-136 watts, and like most modern LCDs the maximum brightness levels are too high to use comfortably outside of an exceptionally bright area (because otherwise they'd be too dim in places), so you won't be running it at maximum brightness unless you're working outside in the desert.

    Not exactly right i guess. Every now and then there are some good RGB LED monitors in the news (at least on paper)... e.g. the LaCie 730 (http://www.lacie.com/products/product.htm?pid=1109... I don't know for sure if its any good 'cause i only have a poor Dell U3011 on my desk, but who knows?! ;) Reply

    You should have passed the test for "Professional display equipment 101" instead. Reply
