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

Viewing Angles
Viewing angles are one of the specifications where manufacturers' claims bear scrutiny. The basic requirement is that a display has to maintain a 10:1 contrast ratio in order to qualify as "viewable". The reality is that most LCDs are unfit for viewing beyond a 45° angle. The good news is we doubt that most people will view a display from anything more than a 45° angle, and typically a lot less. For that reason, we used our camera to take shots from head-on as well as from the left and right sides at ~30° angles, showing how brightness and contrast ratios change in off-angle viewing. We also took pictures from above and below at ~30° angles. Links to the viewing angle images of previously reviewed LCDs are available for comparison below:
Acer AL2216W
Dell 2405FPW

Dell 2707WFP

Within our 60° viewing arc, the colors and image quality of the w2408 clearly indicate the use of a TN panel. From the left, right, and above the w2408 maintains reasonable colors, but from lower angles the display quickly becomes unusable. If you have any short people (or children) around and you don't want them seeing what's on your computer display, then this might prove useful. Sitting directly in front of the LCD, or slightly above center, issues with viewing angles should not be a major concern. Still, it's difficult to justify the purchase of the w2408 over similarly priced models that use S-PVA panels.

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.
