HP w2408: A "New" Twist on 24" LCDs

Subjective Evaluation
As usual, we spent some time using the display both before and after calibration. Many users don't have access to color calibration tools, while for imaging professionals some form of hardware calibration is standard procedure. We will start with our subjective evaluation before getting to the actual quantitative results.
Not surprisingly, something we noticed almost immediately is that the viewing angles on the HP w2408 are not as good as other 24" LCDs we've tested. Even without specific knowledge of what LCD panel HP uses, we could tell that this was a TN panel. However, while the viewing angles clearly aren't as good as what you might see on S-PVA or S-IPS, you won't normally notice when you're actually sitting in front of the display and using it. The viewing angles also appear to be better than what we've seen in previous TN panels, so there are improvements relative to older TN panels.
Running at the native 1920x1200 resolution, text and images look crisp and the colors are nice and vibrant. We tend to prefer LCDs that don't have a glossy finish, as the reflection can sometimes be distracting. However, glossy finishes can help to improve apparent contrast and color quality. Opinions differ as to which option is best -- glossy or matte finish -- and there are benefits and drawbacks to both options. Just try to avoid leaving fingerprints on your glossy screen.
One issue that we did notice with the design is that rotating the display into portrait mode can be a bit clumsy. First, you need to raise the stand to its maximum height; and you need to tilt the display back in rotate the panel. Only after doing this can you tilt the display back to its normal position. What's more, while we found that the integrated cable management system generally works well, if you're not careful you will dislodge the power cord (and possibly other chords) when rotating the panel -- the cable management tends to "grip" the cables a bit too much.
Functions for tuning the display output using the OSD are good, allowing you to adjust contrast, brightness, as well as individual color levels. The default settings are very bright, as usual, and we quickly turned down the brightness to 40%. Tested power draw was also substantially lower than the stated maximum of 130W; even at maximum brightness we never measured more than 85W peak power draw, and typically the display used less than 80W.
One final interesting addition is the ambient light sensor, located in the top-right corner on the front of the display. If you activate the ambient light function inside the OSD, the display will adapt its brightness levels dynamically. That might sound somewhat useful, but considering brightness affects color accuracy, the only reason to use it appears to be laziness - or if you just like new features. If you're in a dark room and someone turns on the light while you're working at the computer, it's also a bit disconcerting to see the brightness suddenly increase slowly for a couple seconds. Ultimately, we rank this feature in the same category as HDTVs with "ambi-light" - where the sides of the TV project colors to "enhance the ambience".
Unless otherwise noted, we ran the remaining tests after calibrating the displays using Monaco Optix XR, both the professional version of the software as well as an XR (DTP-94) colorimeter. In some of the tests calibration can have a dramatic impact on the result, but viewing angles and response times remain largely unchanged. We also performed testing with ColorEyes Display Pro, although the overall results were better using Monaco Optix XR.

It's partly an issue of getting enough reviews done so that more manufacturers are willing to work with us on monitor reviews. Things take time, and sometimes we go through periods where nothing new comes out for a while. I've got at least a few more LCDs coming shortly, and I hope many more post-CES will get sent our way for review.GlassHouse69 - Saturday, December 22, 2007 - link
IPS panels are the best for all things. some s-pva or mva's are close competitors to ips but still have colour errors and colour washout on angles over 20 degrees from center.tn panels shouldnt be priced higher than 350 dollars. one could get an almost 0 lag (15-19ms) 24" s-pva panel from LG and be more pleased for gaming and general use for 500 dollars.
i paid a grand for my 26" 1920x1200 H-IPS panel from planar. it is incredibly clear and accurate and has less than 1 frame lag. spending 550 dollars on a tn panel vs 900 dollars on a IPS pro fessional panel... sux cant see the point/value.

Have you lurked in the xtknight's LCD thread at the forums?Perhaps you might get ideas about what people seek from reviews and what kind of LCDs they seek.
For me it seems that there are more interesting LCD models out there than reviews of LCDs. Pretty much the opposite situation when compared to GPUs or other less subjective review targets.
Anandtech LCD reviews seem a bit bare for me, as there are less measurements than in some other LCD review sites. It is difficult to say if reviewers at the other sites measure things that I would notice though, or if the extra measurements just generate artificial desires. Input lag measurements at behardware or RTC error measurements at xbitlabs are interesting, for example, but I don't know if I would be bothered by less than ideal results in actual use.
PS. The old comment system was better - no need to load/reload the article page when browsing comments.

What is "TN"?How about "S-PVA"?
Bonus question: How do the two differ / which is better?

Well, I could try to explain it, but wikipedia already has a good deal of data on the matter. http://en.wikipedia.org/wiki/Thin_film_transistor_...">This Film TransistorsThe simple answer is that in my opinion:
S-IPS > S-PVA > S-TN/TN+Film
TN panels often have lower stated response times, but frankly I can't see the difference. I can however see the difference between the two in viewing angles and color quality.

I know it should go without saying (and usually does) but thanks for another great review that is so clearly unbiased. Just seems to me that if Anandtech is having a hard time getting manufacturers to send LCDs for review, handing out a negative article on the first offering is probably not going to encourage other manufacturers to follow suite. But the truth is the truth, and particularly after recent high profile events on other sites its nice to get a little reminder of the quality we can enjoy here.(This probably is coming across all doe-eyed fanboyish.. meh. It's just really nice to have trust worthy info sources)

The LG L246WP-BN is a P-MVA panel... it's beautiful and doesn't seem to exhibit some of the colour shifting that some PVA panels do. It'll be either that or Dell's next 24" for my next LCD.gochichi - Monday, December 24, 2007 - link
I recommend it at the $450.00 price tag. I own this display and I am very pleased with it overall. I vastly prefer the HDMI/DVI input as opposed to VGA on this particular display (some displays you literally can't tell the difference, not so on this panel).It is WORLDS better than the cheapish 24" Samsung. Samsung is building an overinflated name for itself... that or they are seriously risking their brand name over some "too good to be true" products (they really aren't good when you get them home).
I more than ever depend on review sites and user comments to help me navigate the sea of available products. I personally believe that the Dell is superior to the LG 24", however, the LG is more readily available at retail stores and a fantastic deal at $449.00.

I would like to see how HP plans to really markey this screen costing what it does and doing so litle for its return really. Right now though I am using my HP 42" Plasma as a monitor. I can honestly say it looks much nicer than the LCD equivalent. It would be nice to see something between the 42 and 26 size range though.LoneWolf15 - Friday, December 21, 2007 - link
$570? I paid around that price a year ago for a Dell 2407. I got an S-PVA panel, additional inputs (component, s-video), 9-in-1 card reader, 4 USB ports, and I got the five-year warranty.If HP thinks they can sell that panel for $570, they need to think again. 6-bit color, poorer viewing angle, limited inputs --you can do better for your money.
