A New 30" Contender: HP ZR30w Review
by Brian Klug on June 1, 2010 6:30 PM EST
Brightness Uniformity
In addition to the performance at center, we’ve also added 9-point testing for brightness, both white and black. This is done the same way we measure color uniformity, except we only care about measured intensity. We set the monitor through the "OSD controls" to near 200 nits, and then measure those 9 points.
White Level Uniformity
Black Level Uniformity
Our plots here do exaggerate differences - the ZR30w is remarkably uniform with an average brightness of 203 nits and a standard deviation of 6 nits. There’s a bit of a pattern for white, up top there’s a measured falloff compared to the rest of the panel, but visually I couldn’t discern any difference. It seems that under 10 nits is difficult to really discern.
Blacks are a similar story - they're very uniform. The average is 0.31 nits with a standard deviation of 0.019. There’s a slight brightness difference horizontally across the display, but again even after intense scrutiny I couldn’t discern anything. Brightness uniformity is impressive as expected.

Thanks for the review, but I think most people would be more interested to see a review of HP ZR24w. Are you planning to review it?Brian Klug - Tuesday, June 1, 2010 - link
Hey, yeah we're definitely working on getting the ZR 22" and 24" displays for review. I know that everyone is very excited for us to get those and start working on em - at least I know I am! Should be within the month.Cheers,
Brian

Only negative is it doesn't do 1:1 display of 1080p inputs...it scales it up to 1200 lines all the time. A bunch of ZR24W owners have filed bugs w/ HP, but no word on getting this fixed yet :-PIf Anand could check this and gripe as well, it might help :-)

Good review, useful data.I do think the input options are just right for this: DVI+displayport. This is a PC monitor so these are the right options. Devices that use hdmi (consumer electronics, smartphones etc.) generally can't output 2560x1600.

Yeah, but my personal Dell 3007 WFP-HC's DVI-D only means I can't hook up my work Dell M6400 laptop, as it has VGA and DP outputs only. I need a docking station for the two to mate, though I can't convince myself or the office that it's a worthy expense.More inputs is always better, even if there are downsides to the others (clarity, lag, etc).

while i agree that added connectivity is always a good thing,if the lack of extra inputs shaved a $100 off the price, then it's why i, and a lot of other folks will buy one.

Display Port can be converted easily with an adapter to HDMI (with audio if your laptop supports audio with DP) or even DVI without any difficulties. And the adapters are fairly cheap and small.erple2 - Wednesday, June 2, 2010 - link
Does HDMI even have the bandwidth to support the native resolution? I don't think so - it's limited to at most 1920x1200.It therefore makes perfect sense to me to not include an HDMI connector.

As of HDMI 1.3 the max resolution is 2560x1600p at a 30 bit pixel depth. HDMI 1.4 will do 2k and 4k over single link to a resolution of 4096x2160p at up to 36bit pixel depth. (referenced from wikipedia for concise comparison charts). That is not to say that any given HDMI output to a device, or for that matter, a display port adapter will be able to deliver it due to the individual ports build, but it is possible under the right circumstances.samhall - Monday, January 9, 2012 - link
just wondering if anyone knows how to connect an xbox up to this monitor. I have connected it by getting an addapter for the DVI-D port but cant get anything on the screen.Can someone help Please??????
