I wouldn't go so far as to say he has posted any facts. He hasn't substantiated any of his assertions. I just hope no-one has actually listened to him and wasted their money based on his strawman arguments.

T2K, you may be right that the panels aren't the same. I think I found the listing of panels that I remembered reading, but it doesn't include the ZR24w (not sure why I thought it did).

Philips 240PW9EB ............ LG.Display H-IPS (LM240WU4) panel
HP LP2475w ................... LG.Display H-IPS (LM240WU4-SLA1)
Dell U2410 ...................... LG.Display H-IPS (LM240WU4-SLB1)
HP LP2480zx ................... LG.Display H-IPS (LM240WU5) w/A-TW
(http://hardforum.com/showpost.php?p=1035502137&postcount=302)

You have yet to explain why you believe that a monitor that outputs fewer colors in the standard gamut range has better color reproduction in that range.

Here's a link to the data sheet for the ZR24w:
http://h10010.www1.hp.com/wwpc/pscmi...eet_120409.pdf

Panel type
S-IPS (H2-IPS technology for improved energy efficiency), Wide-Aspect, Active Matrix TFT (thin film transistor)

Well...been itching to buy since I heard and saw this, so I finally ordered it today. Hopefully, I'm not disappointed. This will be my first IPS panel.

Oh dear, the black depth and contrast ratio are markedly worse than the LP2475w or even the Dell U2410. I don't expect superdeep blacks from a non-plasma display, especially if it's not PVA, but I suppose I think of 500:1 static contrast ratio as 'acceptable', and the ZR24w only rates 425:1. Mmm.

That said, TFT Central judges the ZR24w arguably the better purchase, especially given its price -- unless one needs a wide colour gamut of course.

Thats just silly to accept a 425:1 ratio, It's 2010 folks. My Dell 2001FP from years ago was rated 400:1

Well, IPS panels have never had the best blacks and contrast ratios. The PVA-panel Dell 2408WFP got blacks as low as 0.16 and a static contrast ratio round 1000:1 (its dynamic contrast control could get the black as low as 0.06!). And of course that's not even bringing plasma into the contest (my Pioneer KURO has blacks round 0.03 and a contrast ratio nearly 9000:1 apparently :eek: ).

Still, I'm not sure that I'd find 425:1 that much worse than the Dell U2410's 540:1, but falling below 500:1 is psychologically distressing.

Got mine on Friday, and after fiddling around with the brightness and contrast settings on the monitor and using the color calibrator in Windows 7, I think the blacks are just fine.

Comparing it to my Samsung XL2370, I have to say this HP is pretty close in blacks. Colors are definitely better on the HP, and I'm definitely glad I bought it.

Does your anti-glare screen create a shimmering on solid colors, for instance the colors on this Anandtech pages especially the light blues whites and greys?

Not sure what you mean by shimmering, but if I go full screen and get really close, I can see a graininess in the whites, however, when I lean back to about 2 feet or so, I can't tell.

I like the fact that this screen has a matte coating instead of the glossy one I used to have on my previous monitor, a HP 2408w.

problem with tftcentral's cost comparison is they have some problem being the UK that the price is different, since on ebay the u2410 rev A01 can be had for roughly the same price from time to time.

i am trying tftcentral's icc, which they used to nearly halve the blackpoint, but im pretty sure it's not being applied on this monitor properly, maybe because of the gfx card driver. (maybe I need a weird icc that will definitely look odd, if applied, that i can try out.) Of course in doing this it is a terrible assumption that this monitor is a clone of theirs, but it's something to try.

also, on the one i was using, there was nonuniform / asymmetric blacklight bleeding / glow, some sort of odd quality degradation of the pixels in the bottom right corner, and a few dead pixels that came alive after some use.

just like the previous poster, i can also tell a little graininess. for the blacks, beyond calibration, which can make a significant difference according to tftcentral, the dynamic contrast ratio can also be switched on, though the effect on even completely dim scenes, e.g. a black backround, was found to be fairly minor.

edit:

for people who are looking to buy this, overstock has it at 425 + 3 dollars shipping - 42.5 (10% coupon code 148945) - [cashback]

[cashback] is bing at 10% possibly (search (aurora walk in tub) for example), though bing is likely to be voided with use of a coupon codde. There is also fatwallet at 4%, bigcrumbs at 5.6%, shopdiscover at 5%, etc. (cb stackability ymmv)

I'm afraid that reading both reviews is pushing me back towards the Dell U2410. FlatpanelsHD agreed in many respects with the TFT Central review: pretty good default gamma and colours, inferior blacks, and disappointing static contrast ratio. They seemed to take a slightly harder line than TFT Central.

I was especially intrigued to see that FlatpanelsHD felt the $300ish NEC EA231WMi was a superior monitor (though of course one gives up 120 vertical pixels).

If we put aside price for now (er--and the reportedly high number of questionable panels in Dell's monitor line), would anyone in fact say the HP ZR24w is superior to the rev A01 Dell U2410, even in the sRGB space? I was rather disappointed by the banding that FlatpanelsHD observed. And those of us who would like to watch videos and movies on our computer monitors may be worried by the HP's poor blacks.

Time to wade through the respective threads on Hard|Forum again...

Right, that's one of the facts I posted early on, that it is a newer S-IPS (often called e-IPS) vs the more expensive and advanced H-IPS in U2410 (renaming a little bit less energy-hungry S-IPS panel to "H2"-IPS is a rather pathetic, Nvidia-like gimmick IMO.)

It's a good list, I think: http://www.tftcentral.co.uk/search.php?query=h-ips&select=panel

You have yet to explain why you believe that a monitor that outputs fewer colors in the standard gamut range has better color reproduction in that range.
I don't think I'm following you... so you're saying the cheaper 8-bit panel in this HP has "better" (whatever that means) color reproduction than the panel in U2410 that not only goes beyond 8-bit when needed but also drives couple of the best ~24" graphic displays ($2k+ Eizos) on the planet...?

Sans few early enthusiasts who does not own either but wanted to save some money I don't think anyone ever claimed it... ;)

OK guys, this seems to be a good place to get some help. I followed the discussion but still decided to buy the Dell.

I just received my U2410, A01, and I am really impressed with everything but the colours. In fact, I feel there is a clear green tint in the standard settings. So far I am using sRGB settings, which seems to be alright. Even though I am not doing any serious photo or video editing it puts me off that such a monitor has this issue. I am using it for 70% office work, 20 browsing and 10 photo&Video.
I need this monitor due to its brightness, resolution and PIP function.
Could you guys give me some hints as far as calibration goes and some points how to further check the quality of my display?
Thanks. How do I best check the back light uniformity?
Cheers

This thread is actually about the HP ZR24w, so you may have more success in a U2410 thread. I don't know if there are any already started here, but this one is pretty extensive:

the zr24w looks like a nice monitor, but for $75 more it seems like the u2410 is the better buy.

Because 16:9 is the suck? Why buy a 16:9 when 16:10 offers more pixels and can run 16:9 as well?

This new monitor from NEC uses a 10-bit P-IPS panel with a native resolution of 2560 x 1440. It's very expensive at around $1300 to $1400 currently. I'm wondering if there is any input lag associated with it.

Edit: Ooops, sorry. Should have made a new thread.
