Well haven't i had fun trying to track down an H-IPS panel....not.
After the appalling experience in trying to order one from a certain company "KucO" who seem incapable of a)giving an honest answer and b) maintaining accurate stock levels (when does 10+ = out of stock?Answers on a postcard please), i then went a-hunting at all the companies listed on a google search.
All seem to list the S-IPS panel, and none could give me the manufacturer date, so get this......

I followed the link on Bit-tech review from the price which took me to the "LCC" website--i sent a message asking them to verify the panel and this is the response i got:
Good Afternoon

Thank you for contacting "LCC" Computers Ltd.

Unfortunately this monitor appears to come with the S-IPS Panel not H-IPS. I have checked the manufacturers website and even they specify that the monitor is S-IPS. Just a tip that Bit-Tech don't always offer accurate reviews and are occasionally wrong. Apologies for any inconvenience caused.

Regards,
*****

So i ordered from "Reyub-e" as they were the cheapest and am relying on potluck! It's arriving tomoorw (saturday), so we shall see what we shall see.
Hopefully others will have better luck in sourcing this product--i`ve lost hair over it!

I see. Well I'm trying to get a post-March 2009 unit myself ATM. It's been an absolute nightmare. So far I've been through:

Original unit: GIG-122 with GIG-045 F/W.
Replacement unit 1: GIG-133 with GIG052 F/W.
Replacement unit 2: GIG-122 with GIG-045 F/W.
Replacement unit 3: GIG-122 with GIG-052 F/W.

They just keep sending me one or another ancient refurb, even though I've expressly demanded a GIG-143 unit with GIG-068 Firmware.

I think I'm entitled to a March 2009 unit or later as my original purchase was made in May.

I'm currently waiting for them to reply about my fourth replacement... :(

Just took receipt of my new LP2475w ordered direct from HP. It is hardware revision GIG153 with firmware GIG072 manufactured July 2009 in Poland.

Isn't your input lag testing method flawed? Your "control" monitor, the 3007WFP-HC, is regarded as having low input lag, however is does have lag and like all LCDs does vary up and down. Typically the input lag of a 3007WFP-HC is given as min 0ms, avg 11.5ms, max 27ms. Therefore saying that the HP LP2475w is 4ms slower than this isn't very helpful. Please consider re-testing against a CRT so we know what the true input lag is.

update 05/09/2009

fyi the unit i received from ebuyer is model num: K9911AT LP2475W (HSTND-2421-A)

Manufactured June09, CZECH, Rev GIG143

It's a lovely, if massive, display with great viewing angles, but is it worth 200 quid more than the 24'' samsung i bought a few months ago.....?? It may well have been, had i not bought the Samsung!!:)

Any high end panel monitor is usually worth the price if you don't plan on a replacement for a while. That said, after borrowing the HP for a bit, NEC still retains their awesome build quality.

after being turned on with the PC running it writes no signal, goes to sleep and then finally goes on.

is this standard with these big high-end monitors??
Elton 6th September 2009, 17:21 Quote
It's common with almost every NEC I've seen, I'm guessing because the GPU hasn't sent out the signal yet, seeing as you did turn on the monitor first.
antaresIII 6th September 2009, 17:48 Quote
I meant when you turn the monitor off with the PC running and then you turn on again (on simple monitors you get the picture at once).

It's true a CRT has practically no input lag but the 3007WFP-HC is pretty much the fastest panel around as it has no post processing. We feel it's more appropriate to compare new monitors to a TFT that's the best in it's field in terms of input lag like we would a slow graphics card to fast graphics card. After all, you wouldn't go out and buy a CRT instead would you?

In all the tests we've done, the difference in input lag has been consistant where there was any with 1ms difference at most in our test after several goes so we have complete confidence in it's ability to produce repeatable results.

I ordered a LP2475w off ebuyer a couple of days ago and it's been shipped. Once it arrives, I'll check the manufactured date and model revision.

Does it say anything on the box or do you have to open it to check?

Making sure it's an H-IPS

Got Monitor rev143 and firmware068. Looks like a pretty good one, only IT Troll has something newer.

Quote: " 1,920 x 1,200 resolution means that you can play 1080p video without the need to crop "

That is not totally true.

1080p is 1,920 x 1,080 resolution.

You can't fit a 1080p movie in this monitor's screen without either cropping, or using black bars to fill the sides, or stretching the vertical lines so that peoples faces and objects in the movies look warped and skinny.

I heard that PC monitor manufacturers choose to use the 16:10 aspect ratio instead of the proper widescreen aspect ratio of 16:9 because they want to give the PC user the ability to fit the video AND windows taskbar on the screen together at the same time. If this is true, then it doesn't make any sense. People who watch movies on their PCs don't want to watch the taskbar. As soon as the movie begins, people tend to put the movie on full screen mode.

Anyway, apart from the negative 16:10 aspect ratio objection, this screen definitely looks good. I like the thin symmetrical neat bezel. A few of these screens would be good for multi-screen gaming.

I'm horribly confused.

I'm still running on a Philips 19" CRT and have been for 6 years now as I've had no intention of purchasing a TN panel. Finding a IPS panel in South Africa has been a long wait. I'm a reseller of hardware and one of my suppliers has this HP panel, but they might have had it long enough for it to be an older revision. I'm not sure if they'll open the box to confirm before I purchase.

I'm not too comfortable with the stories about squealing and the odd colour shifts on the new panels. Do those colour issues go away with calibration?

The other monitor I might look at is the NEC LCD2490WUXi2. It has a less wide colour gamut than the HP, but has a A-TW polarizer. On tftcentral it achieved better calibration results than the HP, but lost out on black level. When that came right, it wound up having less accuracy than the HP. An article on X-bit as found through tftcentral shows that a wider gamut isn't always the best.

Has anyone here had the HP and the NEC together at the same time or actually have both of them to offer an honest comparison between the 2? Should I be worried about the unit(s) my supplier is offering or perhaps worried about the longevity of the HP (those squealing noises usually lead to a dead LCD in my experience) or should I just suck it up and ask the NEC rep for a LCD2490WUXi2 and go for brokedom?

Might have solved my dilemna... NEC doesn't have HDMI, component, composite or s-video inputs. Need this thing to hook up to an analog source (D-SUB) as well as a digital (DVI or HDMI) source with possibility of component as well. :P

Hi. I found a new version of this. Does anyone got idea if this has a H-IPS panel?

Manufacture date: October 2009
Rev GIG153
Firmware Rev. GIG076
Model no: KD911AT HSTND-2421-A

So whats involved in ensuring that the monitor i buy is the newer panel ? Is it really a complete gamble ?

Not really as both the S-IPS and H-IPS versions are excellent.

This is most undoubtedly an awesome monitor.
I have just recieved mine today and thought I'd post here so folk would know where to get a new revision from.
I ordered mine from Expansis (UK store) and I must say the experience was fantastic. They did everything they could to help.
In the end I recieved a monitor with:

Manufacturing date- Feb 2010,
Monitor Rev- GIG:173 and
F/W Rev- GIG:077

I've just placed an order of this monitor from it247. They are reporting on their site that the monitor is S-IPS:

http://www.it247.com/product/1/HEWCMB10/KD911AT-ABU-HP-LP2475w-LCD-display-TFT-24.html

Are they reporting that incorrectly or will it be H-IPS when I get it? The thing I am worried about is that they have over 200 in stock and as such I imagine they will be trying to shift out the old stock.
