Screen Size (inches)	22" Wide
Resolution	1920 x 1080
Brightness (cd/m2)	250
Brightness, also known as luminance or photometric brightness, is the luminance intensity of any surface in a given direction. It is measured per unit of projected area of the surface as viewed from a single direction.
Contrast Ratio	10,000,000:1
Contrast Ratio is the difference between the whitest white and the darkest black colors the display can show. The greater the contrast, the better the screen and the subtlety of colors it can display.
Response Time (ms)	5
Response Time is an attribute that applies to LCD monitors. It translates to the amount of time it takes for a liquid crystal cell to go from active (black) to inactive (white) and back to active (black) again. It is measured in milliseconds or (ms). Lower numbers mean faster transitions (eg. 16 ms is faster than 25 ms.) and therefore less visible image artifacts.
Video input	Analog RGB, Digital
Color Depth (mln)	16.7
Color Depth is a measurement used to describe the monitor range of colors. The higher the color depth, the wider color range displayed.
