HP ZR2740w - High Resolution IPS that Doesn't Break the Bank
by Chris Heinonen on March 16, 2012 1:15 AM ESTColor Uniformity and Color Gamut
The calibrated results on the ZR2740w were pretty good, but with such a large panel was the uniformity going to suffer because of it? 23” 1080p displays have a hard time with uniformity and are easier to fix, but perhaps since the HP is a higher end display more work has been put into keeping the screen uniform all around. Measuring nine points around the screen at the 200 nits calibrated setting, you can see what we found.
Only one of the nine locations had an average dE above 3, and the median value there was still below 2.75. What concerned me the most is that the uniformity on the grayscale was so bad, so when you have a solid white background, which is likely on a monitor like this with spreadsheets and other applications, you will be able to clearly see a shift in the white point as you look at it. Colors were far more consistent than white was across the display, so it seems to be a shift when the panel is fully driven, probably due to unevenness in the lighting I would assume.
While it has an 8-bit panel and can do 10-bit colors with A-FRC, the backlight system of the HP means that you aren’t going to get the full AdobeRGB colorspace on it. The HP comes out of Gamutvision with 76.82% of the AdobeRGB space, pretty much dead on to the 77.2% in the specs.

"nothing even close" is wrong. There are plenty of other monitors exceeding its performance, particularly the 120hz refresh rate. I'll take an Acer GD235HZ ANY day over the zr20w. 30" is way too big for fps games I play anyhow. 'Gaming' monitors are all relative to what type of games you play. In super fast twitch fps games like Quake/Unreal/Tribes, you're going to easily notice the difference in smoothness and seeing whats going on around you during dynamic fights requiring constant 180+ degree turns. And you don't need a $2200 fw900 to get a great crt. My CPD-G520 is just as good as the fw900, except it doesn't hold the wide resolutions (un necessary for gaming, 4:3 or 8:5 is fine by many). and can be had on craigslist for less than $100.thunderjunk - Friday, March 16, 2012 - link
The best part of the article is the Buy.com add at the top of the page. Selling this monitor for $888.99. I noticed it RIGHT after i read "... a street price that comes in at $700 or below..."I then immediately facepalmed.

Ha... unfortunately, we don't control the linked in ads or where the prices come from. Many places sell it for under $700, so boycott Best Buy. :-)Chapbass - Friday, March 16, 2012 - link
I know its popular to bash best buy, but thunderjunk clearly said buy.com, not best buy...Kjella - Friday, March 16, 2012 - link
Hehe I've had the same thing at our national version of pricewatch... I just searched for best prices for component X, then I get an ad out on the side offering the component for a much higher price. It's like "come to us, our prices are SO much higher". That's what you get with keyword advertising.ComputerGuy2006 - Friday, March 16, 2012 - link
id pay over 2k easily for a monitor that does 2560x1600 @120hz.If they can do higher resolutions on TV's or higher DPI on phones, why cant we get a legit monitor with a better res then 2560x1600 or a better refresh rate then 60hz?

That's 11Gbit/sec (24-bit color x 2560 x 1600 x 120), a lot of data to process... on a 1920x1080 TV it's only 6Gbit/sec.It looks like DVI does 1.65Gbit/sec per wire pair, with 3 pairs in a standard DVI cable (4.95Gbit/sec) and 6 pairs in a dual-link DVI (9.9Gbit/sec). http://en.wikipedia.org/wiki/Digital_Visual_Interf...
So, even a dual-link DVI cable couldn't support 2560x1600x120Hz. Looks like it's time for triple-link! :-)

Displayport could handle it though. 17.28 Gbit/s for the newest standard.B3an - Friday, March 16, 2012 - link
DVI???It's not 2005 anymore :)
Theres Display Port 1.2 and HDMI 1.4 now. All my 2560x1600 monitors have both. And higher end AMD cards have had both as well for some time. The 6000 and 7000 series have DP 1.2 which should be able to handle 2560x1600 @ 120hz.

It should be able to handle 90 Hz at this resolution, though. And the panels should be able to handle it, too.
