NEC PA301w: The Baddest 30-inch Display Around
by Brian Klug on March 1, 2011 8:00 AM ESTBrightness Uniformity
For brightness uniformity, we test at the same 9 points we measure Delta-E on, but this time measure white and black levels when the center point is as close to 200 nits as we can get. We use the same colorimeter and software as before, - an Xrite i1D2 and ColorEyes Display Pro. Similar to the ordinary brightness test (taken at the center), contrast is set to 100 in the OSD and brightness is set to as close to 200 as possible in the center before measurements are taken.
White Uniformity
Black Uniformity
It appears that the PA301w's built-in uniformity settings help keep the brightness profile very steady in the full on white test. There's a tiny horizontal dependence from left to right, but it's imperceptible in practice, and the standard deviation of these readings is just 4 nits. Uniformity in the white department is actually very good.
Blacks are a little worse, again the bottom left seems to be brighter than the rest of the display by a measurable and consistent amount. On the whole again though the consistency is pretty good. Displaying a purely black image, there's also no obvious light leakage anywhere on the display.

Imagine gaming with 3 of these. wowee wowee wowee.Now imagine having to work for weeks on end to be able to pay for them. lol

I'm definitely not educated on the subject, but wouldn't the response time be detrimental to most gaming?But from a purely size and resolution standpoint, it would be pretty neat.

If it's the same 2 frames as the 3090 had it's only really going to be an issue in FPSes at higher skill levels and on a low latency connection. For anything else it's fine.softdrinkviking - Tuesday, March 1, 2011 - link
I have the 24" version of this. (it's available where I live) and it's fine for gaming. There is some acceleration hardware inside that seems to work well. It's fine for sports or movies to me.Perhaps you are more sensitive than I, but I think it looks fantastic.
Interesting note though. The contrast ratio on the NEC PA series monitors that I've seen is 800:1, whereas the other series they make, the LCD2409, 2609, ect, are H-IPS, and list a higher contrast ratio of 1000:1.
I noticed this when shopping, printed on all the little spec cards at the store.
I wonder if this is a trade-off for the better color depth of the S-IPS panels?
I understand that the contrast numbers given can vary in actual meaning, but I'm assuming NEC uses the same criteria for contrast across its professional line.

The kilowatt is equal to one thousand (10^3) watts. I think this is what you mean by Kill-A-Watt.LukeDK - Tuesday, March 1, 2011 - link
A Kill-A-Watt is a device used for measuring power consumption (or voltage, current, frequency, etc) at the plug.LTG - Tuesday, March 1, 2011 - link
So nice to see someone point out a correction without insult or condescencion.MobiusStrip - Tuesday, March 1, 2011 - link
