Asus ;
Similar can't be said of the actual image quality of the display, though. You wouldn't realise this from the spec sheet, which talks excitedly of a 50,000:1 dynamic contrast ratio (no native figure is provided), a brightness of 250cd/m2 and a 2ms grey-to-grey response time. But, as we well know, such figures are generally very misleading. Much the same can be said of the 170 degree horizontal viewing angles, which are somewhat optimistic.
In reality, the MS236H is average: nothing more, nothing less. Its colour production is okay, its viewing angles reasonable enough for most needs and it doesn't suffer any outstanding motion handling problems, but it stands out in no way whatsoever. Particularly disappointing are both its detail in dark shades and the purity of its black level. Like many cheaper displays based on TN panel technology, it really doesn't bring the finer details out well and dark scenes tend to look a little too grey.

BenQ ;
For those on a tight budget, the BenQ G2220HD will prove a great 1080p monitor, costing no more than you'd pay for a conventional 16:10-format monitor with a lower resolution. An HDMI port and speakers are sadly lacking, but the monitor's colour reproduction is very good.
The G2220HD's image quality is generally quite impressive, although, during our testing, we noticed moderate backlight bleeding when displaying dark images. We've definitely seen monitors that have a worse backlight-bleeding problem, but we've also seen plenty that don't suffer as badly in this respect. The monitor's colour response, on the other hand, is very good indeed, with very little adjustment required during the calibration process. This results in life-like flesh tones and natural-looking photos and video.

And i wouldn't like the weird ring from the Asus, this means you can't look at it at a normal height and you have to look down somewhat.
I rest my case . . .
