All LCDs have certain angles where the colors look funky or dim, but 160° is pretty crappy, most are like 178/178 these days. I doubt it has anything to do with it having an LED backlight though, just a lower quality panel.

Always try before you buy. Even if the best price is found online, find a store nearby that carries similar models from the maker to see in person. Especially if it is something that needs to be seen to work properly. We aren't talking about RAM. No one stares at their RAM for hours, but you have to see a monitor. That is it's sole purpose.

If you are unhappy, return it.

Only VA and IPS panel monitors are 178/178. TN panel monitors typically range between 160/160 - 170/170; TN panels have the most color shifting.

Traditional LCD monitors use CCFL (florescent) backlight.

"LED monitors" use LED instead of CCFL. They also tend to look slightly bluish to some people.

jaguar nailed it. If you want acceptable viewing angles, you have to go with VA or IPS LCDs. Asus has a couple of these for decent prices if this is a huge deal. If you are interested I can give you links. But to answer your question - no, for TN panels (almost all 'consumer' grade monitors) poor viewing angle and color is the norm.

And the backlight has minimal affect. Most LED backlight (I hate how they just call them LED these days) monitors are just ring LED, which means there is a ring of white LEDs around the outer edge of the monitor. This allows them to be extremely thin, however they do not produce necessarily good color or uniformity. They do seem to use about 1/2 the power of conventional CCFL (due to them being in a ring rather than one source). A 'true' LED backlight monitor has RGB LEDs behind every pixel giving extremely good color and uniformity. However they are also extremely expensive and only for the most color sensitive applications.

I am glad you found your solution. I know this site pressures those who create a post to choose a best answer, but you worked through this one yourself so ignore that or choose your own post.

Now, for the rest of you elitist post'ers. If you are running on a $1k+ monitor, than you should help him, but looking at your systems, you are simply saying, "GET THE BEST!" while you settle for...clearly not the best. I mean, look at your "future system" EXT64: Your "future" build includes a 5850. Really? Am I reading that right?

I stand by my statement, which wasn't the most specific, but clearly the most helpful. When it comes to things you have to look at and live with, go see them in person. I couldn't have been more helpful of the problem. This whole..."buy a better monitor...loser" thing doesn't help anyone. How about you buy a book called, "Helping, even for idiots".
