As many today's "cheap and fast" LCD monitors this one is a 6 bit screen. This said it can only produce 262,144 exact colors - and do this very fast.
Other 16,515,072 colors are produced using very sophisticated Hi-FRC time-based dithering algorithm, that actually flicks monitor dot slightlyat very high frequency.
Most people do not notice HFRC dithering and it does not create any inconvenience for computer related activities or for watching movies or for playing games. Nevertheless Hi-FRC systems visibly change colors shade depending on screen tilt.

So if you are buying this screen for editing images (and I mean at least PhotoShop or Gimp here) or any other application that requires correct color representation you should consider more expensive 8 bit screen.

With exception of this detail the monitor is real value for money.

It should be mentioned that HDMI input and built-in speakers open couple of interesting capabilities for this product.
For example, using (included!) HDMI cable you can easily use it as a monitor for X-Box, PS-3 (but not for Wii) or DVD player with HDMI output. Or you can connect it to your cable provider hi-def box therefore instantly converting monitor to small HDTV. The only problem is quality of integrated speakers - see below.

Well, I am still using it as a computer monitor, connected by (included!) DVI cable and pretty happy with the image quality. The screen is sharp, bright and I do not have a single dead pixel (but your mileage may vary, of course). Oh, and they include the VGA cable too, just in case.

Other pleasant details are touch controls instead of buttons and a special control for fast switching between Text, Game, Cinema and User monitor profiles.

Acer also includes program utility for some fair color correction, though as I say - if you need a better one, you may need an 8 bit LCD.

There are some drawbacks, of course.
First, the screen cannot be adjusted vertically (but you can adjust tilt).
Second, as I have mentioned, this tilt changes colors slightly. If you look from below, colors seems darker.
Third, integrated speakers are not suitable for stadium concerts... well, to be frank, with 1.5 watt power they barely acceptable as desktop speakers. It's probably a good thing one cannot connect Wii to this monitor, because it will be really hard to hear anything from the safe distance required for Wii controller.

Despite all drawback this is well deserved 5 star product. One cannot expect to buy luxury car for the price of low end sedan. In its category, for this price and as of today this monitor is a brilliant product.
