I see. Regarding the Samsungs, they are 4 years old now so maybe one slowed down more with age?
No. It's more likely the replacement has something different about it, but I still find it strange.

bb23 said:
So the 32ms from DigitalVersus.com was probably determined using the standard timer method?
Yes. I don't consider Digital Versus to be reliable anymore. Some of the results they have published are nonsensical. Lag can't jump around from 0-32 ms. Sometimes the average comes close to the actual lag, but it's not reliable. If they were using a precise testing method, the results would always be consistent.

Edit: Actually, he was measuring the Samsung - here is that link, an interesting read: http://hardforum.com/showthread.php?p=1029433265
He says the ViewSonic VX922 has 15-20 ms when it really has no significant lag, so his results seem to be one frame off. That can happen when using a timer with clone mode because you can't tell where each monitor is refreshing. The LCD might only be 2-3 ms behind due to response times, and clone mode desynchronization can push the refresh back even further, making it look like it's a frame behind when it's not.

bb23 said:
ToastyX, given this method you are referring to, is the CRT all that I will need?
Yes, but it's more likely the screens won't be synchronized when testing DVI vs. VGA. Even if there is tearing, if you wait for the tearing to roll off the screen, the results will be accurate enough. Using a splitter isn't really necessary in that case. You don't need a VGA port. Most video cards can output a VGA signal through the DVI port with a simple adapter.

bb23 said:
Another test I was thinking of, is to use a DVI to VGA adapter and test the HP's VGA port vs. the Samsung. Do you think using VGA might eliminate some lag, as suggested in the article I linked to earlier today?
No. I haven't seen VGA make a difference. That article applies to HDTVs, which tend to do image processing on the HDMI ports. Most monitors don't have a way to reduce lag. The Dell U2410 is a notable exception, where game mode supposedly reduces the lag by one frame, but that monitor has advanced color features, which game mode supposedly disables. None of Dell's other monitors are like that, and game mode is usually just an ugly color preset on most monitors.

Many thanks for that very informative post, ToastyX!

Because this lag issue is still basically unknown, if I were a hardcore gamer and the monitor was mainly for FPS games, etc., I would definitely be buying from HP (or some other vendor) that allows for a 30 day return. Hopefully this will all be a moot point soon - i.e., we find out that the monitor runs games very well. (If you order from HP, remember to call to get free shipping.)

For those who are just joining this thread:

If there are any gamers that have this monitor and can at least give us their subjective impressions, especially relative to input lag, that would be great - and even better if you have a CRT and can do this input lag test, which is very straightforward to do. Thanks.

I second that, and would also like to know if this monitor is giving anyone the screen door effect... Seeing every single pixel annoys me! ;) (a planner at work has an IPS panel that does)

Mine should be here tomorrow. All I do is play FPS games. I'll give a report after some gaming.

There's a test you can do on inputlag.com to check it, but you need to use a decently fast camera to check and compare input lag rates. Ideally you would compare the LCD to a CRT but most people have thrown out their CRTs by now.

I think that 16ms or less of input lag is acceptable for an IPS display. Anything much more than that is dicey and can be noticeable. Certainly interested to see your results on this new hp panel.

Is it in EU, anyone?
In the few places it's listed, they all have an estimate of 1 to 2 weeks before they have it in stock. It's reasonable priced though, the ZR22W on the other hand costs almost as much as the ZR24W which is utterly senseless imho! :rolleyes:

Ha! just got it here at work, and couldn't resist setting it up real quick for an initial look-over (going to be using it at home ultimately).

My first reactions are VERY positive. I can't check backlight bleed well because i can't turn the lights off here (cube-ville), but I booted up photoshop and tested grey/red/blue/green uniformity, and am very pleased with the results. They are on par if not slightly better than my refurb 2090uxi. There is some grain on bright colors/whites due to the matte coating, but it's not too bad. It's about similar to my 2090uxi (from memory), but i can't compare to a U2410 because i don't have one :(

edit: don't see any dead/stuck pixels

HP director of product strategy or whoever was in charge of getting this monitor to market, THANK YOU. finally a high-quality screen for prosumers with a reasonable cost ($409, hell yeah)

Anyway, when I get it home I can take some pictures with a pretty good camera (Canon G10, not a DSLR, but pretty close) next to an NEC 2090uxi and a Viewsonic VA920 (ancient TN). I think it will look good next to the 2090 :)

My credit card company detected "irregular behavior", flagged it as fraud and denied the transaction.

I intend to plug a hdmi device via the displayport, will those displayport to hdmi adapters do the job for the video (I don't care about audio)?

You can't use an HDMI device through DisplayPort. Those adapters are for video card output only. You have to use the DVI port.

An HP 30 day return policy has been mentioned here many times, almost always as something said over the phone by an HP rep.

I've not been able to find anything on-line that confirms it, and would appreciate hearing that there is a hard confirmation somewhere.

Someone mentioned earlier the "screen door effect" and tinting of the screen. I don't notice any appreciable tinting and whatever screendoor there might be I rather enjoy as it makes text and graphics very sharp. Tried several different settings with CCC, OSD, Windows, HP Display Assistant and keep coming back to the stock settings--they please my eye. Seems this monitor is just what it is--a very nice enterprise-class workstation monitor aimed at folks who spend all day looking at text, spreadsheets, graphics. I find it very easy on the eye which is what was hoped for. I did boost the color intensity a bit in CCC and haven't yet gone into control panel and tried the sRBG settings. If this monitor ends up being good for gaming that will be a plus but doubt it was ever designed for that. I did not purchase it for those reasons. Could not be more pleased at this point and it most certainly meets the needs I had in mind. My old Samsung TN panels had begun to make the eyes weary and finding that one "sweet spot" for viewing was tiresome. Can view this panel from almost any angle. Don't game and have a TV for watching movies. Good luck to the gamers and await your reviews--you know what they say--if it is good enough for gaming, it's good enough for anything. Main reason I visit the gamer/overclocker sites--whatever you guys are using has always met/exceeded my expectations

I ordered it yesterday from Cost Central, and Fedex tracking # finally shows up today. Since I'm in CA it says I'm getting it tomorrow. F YEAH! :D

Fortunately a few weeks ago I donated to a non-profit org/client of mine an old LCD monitor, so they were more than happy to let me use what it replaced - a Dell 15" CRT. What goes around comes around.

Anyway, I set it up in clone mode at 1280x1024 using the input lag test ToastyX referred us to here:
http://hardforum.com/showthread.php?t=1423433

So here are a bunch of shots with the Dell on the left, the HP on the right:

1 - HPZR24W vs. Dell CRT

2 - HPZR24W vs. Dell CRT

3 - HPZR24W vs. Dell CRT

4 - HPZR24W vs. Dell CRT

5 - HPZR24W vs. Dell CRT

6 - HPZR24W vs. Dell CRT

7 - HPZR24W vs. Dell CRT

8 - HPZR24W vs. Dell CRT

9 - HPZR24W vs. Dell CRT

10 - HPZR24W vs. Dell CRT

11 - HPZR24W vs. Dell CRT

12 - HPZR24W vs. Dell CRT

13 - HPZR24W vs. Dell CRT

14 - HPZR24W vs. Dell CRT

15 - HPZR24W vs. Dell CRT

16 - HPZR24W vs. Dell CRT

17 - HPZR24W vs. Dell CRT

18 - HPZR24W vs. Dell CRT

19 - HPZR24W vs. Dell CRT

20 - HPZR24W vs. Dell CRT

21 - HPZR24W vs. Dell CRT

22 - HPZR24W vs. Dell CRT

23 - HPZR24W vs. Dell CRT

24 - HPZR24W vs. Dell CRT

25 - HPZR24W vs. Dell CRT

26 - HPZR24W vs. Dell CRT

27 - HPZR24W vs. Dell CRT

I will just post these and hopefully the experts can comment on them. Oh yeah, generally my camera snapped these at 1/60, but sometimes it was 1/40 or 1/30. Not sure if that would matter - I think not, but I am not certain.

After reading the input lag test thread again, I double-checked that the Dell was running at 60 Hz, and Fraps confirmed this. Also, because the camera was not exactly always shooting at 1/60, there is not always just a single bar on the Dell. I don't think that matters.

It does appear on average, at least to my eye, that the CRT is about 1 bar or so ahead of the HP. According to the thread:

"If your display is at 60 Hz, which is 1000 ms / 60 = 16.67 ms per frame, then the difference between two successive frames is 16.67 ms"

It sounds to me that the input lag of the HP is probably around 20ms - very good news, I think, but I look forward to others' analysis.

Thanks to bb23, chris_n, and tordogs for the noise testing. It is very important to me that it is silent. (though I guess we can't be sure yet if the same is true for European voltage)

Reportedly good AG coating, no tints, low input lag (again thank you, bb23), sounds all very promising. :cool:
Still waiting...

I can only agree to PatK about the wide gamut "issue". Unless you have use for the extended color space (which I presume most of us don't), wide gamut will only buy you drawbacks.

Those shots show the HP has no significant lag, maybe 3 ms max + pixel response time. The bars are drawn from left to right, so the newest right-most bar is what you want to look at. The total transition time is less than a frame. The results seem consistent too, with no tearing. Interestingly, picture #20 shows the program skipped a frame for some reason, but that doesn't change the results.

To add to the noise testing, I received my monitor today, and I can't hear it over the sound of my computer's fans. It's very quiet.

I don't have anything to calibrate the monitor (other than the software on the monitor CD and the color calibration in Windows 7), but I did notice that the red was a bit too high at the OOTB setting. As has been mentioned by others, the screen door effect from the AG coating is very minimal and only noticeable on very light backgrounds.

I do have a CRT monitor, but I don't have any sort of splitter to do input lag tests either.

That's great to hear! Thanks for your great input.

Oh yeah, I used a DVI to VGA adaptor to allow the Dell to run off my video card. The HP is on the displayport. The HP had to be set down to 1280x1024. Does any of this matter?

For the above test you don't need a splitter. Just put the HP and the CRT in clone mode, run the test, and shoot the two screens with your camera. (At least my video card did not require a splitter. Dunno overall though.) More tests would be good.

To answer my own question, HP pointed me at the appropriate web page, which is:
https://h71016.www7.hp.com/html/infodesk/returns.asp?jumpid=hpr_R1002_USEN

30 day return for non-defective products from HP Small & Medium Business. $15 [NOT 15%] restocking fee. A very good deal, and worth paying tax for (I'm in California and it's $39.31 in Santa Clara County. YMWV in other CA counties).

I've just ordered. Free shipping is from the Houston, Texas area. Shipper is either FedEx or UPS, depending upon who offers the lowest rates that day. If your preference of shipper is strong enough, you can pay to get whichever you want.

I'll try to get to that tomorrow.

Also, I went here, http://jasonfarrell.com/misc/deadpixeltest.php, and tested for any dead/stuck pixels. I didn't see any bad pixels or sub-pixels.

I'm very happy with this purchase so far.

If anyone has any calibration settings they could post, I'd appreciate it. I realize my monitor won't be the same, but somebody else's calibration settings might be better than how I've got it set now.

Has a gamer got their hands on this yet? I may have overlooked such a post - sorry if so. How does this thing handle FPS games?
