If the HP LP2475w is now a lottery panel, that is bad news indeed:

It seems like HP is doing what Dell has done in the past, used different panels for different production cycles and different markets - In the US the HP LP2475w (KD911A8#ABA / KD911A4#ABA) current production IS NOT IPS (and this was confirmed by several emails to and from HP, with "no comment" on exact panel used other than it was a 24-inch (61-cm) Wide-Aspect Active Matrix TFT (thin film transistor)).

I am still trying to find out what panel is being used in current US production.

The LG W2420P may be still "alive" in some markets (not EU, ?NA?), trying to find out more.

I'll believe it when I see it rather than "confirmed" e-mails through HP. If it is true, though, that's very disheartening if you would be stuck with a TN panel for the price the LP2475w goes for...
 
If HP would try to sell LP2475w with TN panel in its +-500€ price, that would be outright lying and cheating from their part, especially when it is stated in many places around internet with tech specs that it has IPS panel. Good *VA panel MIGHT go just and just with that price, but definetly not TN.
 
No evidence to support this at the moment. Fear Uncertainty and Doubt in my opinion.
 
I ordered one today from HP and the sales guy said "its internal information" when I asked what type of panel it had. When I pointed out the spec on the HP website, he said "oh yeah, IPS", lol. How do I actually confirm it has an IPS panel when I get the unit next week?
 
Thanks for the insight. Does ANYONE ELSE know how to confirm it has an IPS panel when I get the unit?
 
It's trivially easy to tell a TN from the other two panel types - just look at it from an angle below straight on and the TN washes out completely. Telling a VA panel from an IPS panel is a much more subtle task, which is why monitor makers feel like they can get away with switching between them without telling the customer.

Both Dell and HP have been guilty of this before - Dell switched the 2007WFP from S-IPS to S-PVA, while HP switched the LP2065 from IPS to AMVA.

The best description I can find of detecting the difference between VA and IPS is here:

http://monitortest.blogspot.com/

At a sharper angle view the white on VA panels turns slightly pale/yellowish. That is normal for VA.
Originally I was going to post a photo to illustrate this effect. But later I came across the video report from latest Samsung exposition.
Ironically, nothing shows VA's yellow flooding and picture washout better than Samsung exhibition!
Some people mistakenly believe that a violet or so tint of black color (from diagonal view) is a sign of IPS panel. Not at all. A common mistake.
VA panels have that feature too. The Dell 2408 is not an exception.
Is it a problem? Absolutely not. Just remember this when you try to tell one type of the panel from another. Violet tint may mislead you. The only reliable difference is VA’s color shifting while IPS has CRT-like stable picture.
Please watch video supplement Part #2.

Easy. Load up H[]ardForums and look at it from a substantial angle to the side. First put your head at the left side of the screen, then the right. If the grey background on posts turns visibly lighter on the opposite side of the screen, it's VA. If it seems normal and consistent, and only the black shows a silvery shimmer it's H-IPS.

Another characteristic of VA is that if you have your head lined up with the middle of the screen and get a bit close while viewing these forums, the left and right sides will brighten up and give the grey a 3D "metallic" effect.

The latest 24" and 27" panels from Samsung don't show me a yellowing effect. That must be a bonus of using a camera to video tape or photograph them.

I still haven't seen anything that is telling me this is a VA panel. Both Canadian and American HP pages specifically say IPS or (Canadian) S-IPS.

Stop making sense. I'm warning you, it's contagious. :)
 
Quite often, in past situations like this, the documentation leads to different answers because they are using whatever panel they feel like for a given product. It probably has more to do with manufacturing batches than regions really.

That said the panels perform closely enough that most folks won't notice. That doesn't mean the smart souls here won't notice, but simply the reasoning the manufacturer has in why they don't worry about switching panel types.

Additional evidence would be that the documentation stops being specific about the panel type.

It is possible that HP switched panels, an/or used different used different panels for different markets, but I doubt it, as I believe it has always been S-PVA from day one.

You lot are a bit gullible, aren't you?

Some guy runs his mouth off and a whole additional thread has to be created in which to fuss and worry.

Received the HP2475w from HP direct for $569 earlier this week and it looks great. I tried the viewing suggestions above to determine what it is and based on this thread I believe the unit I have is IPS. It pops at 1920x1200 and very responsive, bright at all angles, no color loss or variation at angles, and no dead pixels. If there are any hard factors to identifying the panel type, I'd be happy to do that.
