HP z27x Review
by Chris Heinonen on December 2, 2014 4:00 PM ESTLag is measured using the Leo Bodnar lag tester. It uses 1080p over HDMI so it cannot run at the native resolution. The HP z27x does let you turn the scaler on and off, letting you use a 1:1 pixel mode, so I can attempt to see what impact the scaler makes.
In 1:1 pixel mapping, the input lag is 33ms. Considering there is a 3D LUT in the display, this performance is pretty good. It is still two full frames in a 60fps game, but it might be acceptable to people. Turning on the scaler adds 1.5ms of lag, which is completely inconsequential. Most people will want to run content at the native resolution but if you have to scale it you will see virtually no impact when it comes to lag.
We covered the different gamut options for the HP z27x earlier, but it has a very large gamut in native mode. It does 152.1% of the AdobeRGB gamut, easily the best we have ever measured. If you need to work in larger color gamuts like DCI, the HP z27x has you covered.
At maximum power, the HP z27x uses 61 watts of power and at minimum it uses 28 watts. Both of these numbers are average looking at other 27” monitors, but considering the other features this is quite good. The backlight can produce a very wide gamut and thankfully it doesn’t have to consume extra power in order to do so.

It's probably enforced by the damn HDMI consortium. But that's why it's nice to have displayport on monitors eh. Graphics cards use those and computer monitors like this one do.teddyboyd - Tuesday, December 9, 2014 - link
There are a number of higher rated monitors, I recommend seeing http://www.topreport.org/monitors/ among others.dgingeri - Tuesday, December 2, 2014 - link
I have the predecessor for this monitor, the ZR2740w, and I hate it. I had to have it replaced twice under warranty in three years. The support for it was difficult to reach and difficult to convince I deserved to get a new one because the old ones wouldn't power up at all. (Apparently, they thought I couldn't attach the cable properly, even though I'd worked in IT for over 15 years.) I am simply not getting another HP monitor again because of my experiences. I recommend the same to others.Dell makes much better monitors at has better support. Right now, they have the 27" UHD P2715Q for only $700, including a 3 year advanced replacement warranty. That sounds like a much better deal than this to me.

The ZR2740w, and the Dell, are consumer targeted while the z27x (which isn't a predecessor to the ZR2740w, it's more related to the LP2480zx) is aimed at professionals. Neither the Dell not the ZR2740w have the expanded gamuts or calibration options, they're a different market.fumanstan1 - Tuesday, December 2, 2014 - link
I actually had a different experience with their support for the ZR2740w. Mine started failing where it wouldn't power up either, but they sent a technician out to my apartment to replace the monitor completely and basically came with a brand new warranty without any questions or problems at all. I came away impressed with their support.YazX_ - Tuesday, December 2, 2014 - link
Dell or HP is same rebraded crap originally manufactured in china, you could get same one as these for 300-400$, but the HP logo costs around 1k$.Things extra in this monitor:
LAN: Not important, well external USB 3.0 NIC is for 25$.
USB Hub: not important, costs around 10$.
save your money and get Qnix/X-Star, same quality for fraction of the price, also Qnix comes with Samsung PLS which is better than LG IPS.

You're forgetting the HP logo comes with an excellent on-site warranty, and Qnix tech support doesn't even speak English (they're Korean)wolrah - Wednesday, December 3, 2014 - link
I think you missed the point on the ethernet port. It's not exposed to the PC, it's a configuration interface for the display itself. Still probably unimportant to you as it is to most, but certainly not equivalent to a random USB NIC.ijozic - Wednesday, December 3, 2014 - link
What are you on about? The z27x is a wide gamut monitor, while the ones you mention are not. Furthermore, IPS screens generally seem to have better color accuracy than PLS ones.Samus - Tuesday, December 2, 2014 - link
I had a ZR2740w, it isn't a "successor" to this monitor. The ZR2740 was never a "Dreamcolor" display. As cheinonen said, it's a cheap consumer monitor. I hated it too. I could never get it close to calibrated. But it was a cheap, name-brand 2560x1440 display, and decent for gaming (other than FPS's)
