Earlier this year I was in a similiar dilema as you on what monitor I needed to buy. I noticed between the monitors I had already that colors varied widely. I wanted something that was more accurate so that when I choose a color I knew I was picking the correct one. I also wanted a wide screen monitor because I never had one of those before and I thought it would give me more work space. Overall though I really didn't learn more about the different LCD types until after I purchased a new one.
I had finally decided on the
Dell S2209W which you can see here:
http://accessories.us.dell.com/sna/prod ... u=320-7438If I could do it over again I would have not picked this monitor. While it is true that for the most part everything does look great, and I love the fact that it is wide screen. What annoys me about this monitor is that when you change angles in the vertical direction colors appear to vary widely. For instance if I lean up in my chair the blues on ozzu look lighter, the blacks look more like dark greys, and basically everything looks different. The lower I sink in my chair the darker the colors get and you get a completely different feel. This was exactly what I did not want.
So after my purchase I ended up being dissapointed. While the monitor still does the job, and for the most part it is a very beautiful display for watching videos, browsing in general, playing games, etc, it is just not a great monitor when doing graphic design work as you really have no idea what to expect when you see the colors on other displays (which of course can vary anyway due to the different type of monitors out there).
So after doing research I eventually found out that the S2209W is a
Twisted Nematic Active Matrix LCD type. You can learn more about that here:
http://en.wikipedia.org/wiki/Liquid_cry ... c_.28TN.29In a nutshell the twisted nematic displays are the cheapest to produce, but also have very fast response times. That is why they are great for watching video, but not the greatest when it comes to using it for work. Twisted nematic (TN), are probably the most widely made LCD monitors and I am guessing that is probably because of the cost.
There are two other popular types of LCD panels, and that is
VA Panels, and
IPS panels.
VA panels which stands for
Vertical Alignment Panels would be considered middle of the road LCD panels. Usually in the tech specs of a LCD Panel they will be labeled
S-PVA or
MVA instead of
TN. These monitors are better than TN monitors with the fact that they have better color reproduction and wider viewing angles. The responses times are usually worse than the TN panels though, but for the type of work you are wanting to do that probably wouldn't be an issue. One common problem with vertical alignment panels is color shifting, which is what I am also experiencing with my TN monitor as well.
Finally the best type of monitor which is what I am seriously considering for my next purchase are
IPS Panels. You will usually find these labeled under the tech specs as
S-IPS or
H-IPS. IPS stands for
In Plane Switching and they offer the best image quality, color accuracy, and viewing angles. They are probably the best type of monitor you can get for graphic design where you need to get accurate color representation. They do have slower response times than TN monitors, so if using for games you might notice ghosting / motion blur. However, for graphical work I think these are the types of monitors you would notice a huge difference on. The main problem with these displays though is the cost, and when I was looking earlier this year I could not find any even close to the $200 price range for the size and resolution of monitor I wanted. Typically what I found was about 4-5x more expensive

So for the same size of monitor I have now, instead of paying around $200 I would probably have paid around $1000 to get the monitor.
So to sum things up twisted nematic displays have the worst color reproduction, viewing angles and contrast ratios of the LCD panel technologies, however they are priced well and you could probably find all sorts of bargains with these. VA LCD Panels are middle of the road, so probably an improvement over the TN panels, but expect to pay a bit more for these. They do offer better color accuracy but still having color shifting issues. Finally IPS offers the best of both worlds, only slightly slower response than TN panels, and by far the best viewing angles and color accuracy, however this all comes at a price.
