My GF has that monitor (Hannspree version which is retail product with a larger warranty but otherwise identical). It does not have any backlight bleed on hers and is fairly decent. It is a nice monitor, and display quality is good.
However:
I did buy a Hanns-G 20" monitor for my mom and it did have backlight bleed ontop and bottom.
I also have bought a Hannspree 27.5" monitor, and it fried out on me after a year, but since it's retail product, I was able to RMA it since it has a 3 year warranty, but be warned, HannsG only has a year.
My opinion, it is both good and bad, depending on model and your luck. I'd be nervous to buy one without the 3 year warranty or without an extended warranty from Best Buy or something of the sort.
