I'm looking to replace an old CRT with a new 19" Widescreen LCD and, given my low budget, have come up with a pretty nice contender and was wondering if anyone could help fill in some gaps and offer some recommendations to help me make my decision.
>> The most important question I have, regarding the Acer AL1916W(asd), is the colors. I am unble to find a reliable source to confirm if it is actually 16.7million colors (24-bit) or not as this would be a real deal breaker. Does anyone know or able to confirm this?
And if anyone has any first-hand experience with this monitor (this is the DVI & VGA model) it would be much appreciated - I read a lot of reviews and aside on this model and most are pretty positive aside from some tradeoffs such as bag viewing angles and colors but in general, for the $190CDN price, it seems like a good buy.
Any information, comments, feedback, and/or suggestions would be much appreciated.

Unfortunately you cannot go by that alone. Manufacturers typically state both 16.2M and 16.7M colors for 6-bit panels to confuse customers. 16.8M colors is probably a typo, it most likely should have been 16.7M colors.
A good indication if a panel is 6-bit or 8-bit is the response time. As of right now any LCD panel that lists a response time of 5ms or faster are 6-bit TN panels. The fastest response time for an 8-bit panel is 6ms.
The only way to determine if a panel is using 6-bit or 8-bit technology is to do research. Like many people will say:
"Google is your friend..."
Here is one site that lists some monitors and the type of panels they use:
jaguarskx: So you have can a 6-bit panel that has 16.7M colors? I thought they went hand-in-hand. I get that LG probably made a type (16.8 instead of 16.7) but I was always under the impression that 16.7m == 8-bit. How can they state that 6-bit is both 16.2 and 16.7?
You need to understand how exponents work. The exponent is the number of times a number is multiplied by itself. Also you need to know that a bit is binary. 0 = off, 1 = on.
6-bit panels really produces less than 16.2M colors. A lot less. Monitors have 3 primary colors used to make all possible colors; Blue, Green Red. In a 6-bit monitor each of the three colors uses 6 bits to determine the number of shades. A 6-bit monitor produces 64 shades of each color. 2^6 = 2 x 2 x 2 x 2 x 2 x 2 = 64. Therefore, the monitor can produce 64 shades of Blue, Green, Red. That means 64^3 or 64 x 64 x 64 = 262,144 "real" colors can be made. Thru a process called dithering, the other 16M colors are estimate by "guessing" what they should be.
8-bit panels can actually produce 16.7M colors. 2^8 = 256. That's 256 shades of each color. That means 256^3 or 256 x 256 x 256 = 16.7M colors.
