I just looked @ NewEgg.ca and ended up picking the same monitor Tamz_msc picked.http://www.newegg.ca/Product/Product.aspx?Item=N82E16824236059
Has DVI & HDMI
I have the 21.5" version of the Asus monitor and it works great.
Here's an LG with 30000:1 Contrast Ratiohttp://www.newegg.ca/Product/Product.aspx?Item=N82E16824005129CVF
Has DVI & NO HDMI
Contrast Ratio is like comparing Horse Power. It's a factual number, but it's a number that's tweaked and not always 100% comparable. There are a couple different measurements for Contrast Ratio as well, and companies usually list which ever one is highest and looks best. Plus, just because one has better specs doesn't even mean it's of better quality.
Asus, Acer, and LG all make good products though. I love my Asus 21.5" LCD. Also keep in mind that LG is a TV manufacturer as well, so you should generally expect good quality from them with TVs and LCD Monitors.
