do not get a HP w2408 it is a terrible monitor especially for the price. I had one and experienced terrible back light bleed through along with really bad viewing angles. I switched to a dell 2407wfphc and i couldnt be happier.
It is not just the HP w2408h that has bad viewing angles. All TN panels (the most common, cheapest, and, almost exclusively, the only ones sold at any of your local stores) have bad viewing angles. Especially if you look from the bottom of the scree. In this regard, the HP w2408h is superior to the vast majority of TN panels.
The same can be said about the back lighting. I am typing on one right now, when I switch to the unused input to give me a true black screen, I can see very little discoloration. This is especially true when compared to my old Samsung panel that had bright bars on the top and bottom when the screen was dark.
Yes, your 700€+ S-PVA monitor has much better viewing angles and slightly better color representation than a ~420€ TN monitor. Paying a premium like that, I would expect it to. The biggest issue I have with Dell's 2408WFP (their replacement for your monitor) is the input lag with an excessively high response time, measured over at
AnandTech, of 38ms.
Not trying to push a decision either way, but it is good to have as much information as you can when making a major purchase. With different types of LCD displays, it is all about trade offs. In my opinion, unless you are doing graphical design, a quality TN panel is what you are looking for. Your views may differ but for 90%+ of LCD users, this holds true.
Best luck and be sure to do some through research before you make a decision.
prad.de and
Anandtech.com seem to have some good methodology to their testing and are a great place to learn.
