5.2. Contrast ratio (CR)
The contrast ratio is determined by using a photometer (CA-210) to measure the maximum and minimum luminance in
front of monitor after at least 30 minutes warm up. It shall be test at 1680x1050/60Hz mode and full white/full black
square pattern with contrast/brightness in default value. The values specified are at an approximate distance 20 cm
from the LCD surface and at 0 viewing angle. The contrast ratio is calculated as below:
CR = (Max. full white luminance) / (Max. full black luminance)
CR = 800: 1(typ)
5.3. Response time
The response time is defined as below:
Tr + Tf: 5 msec typ.
5.4. Viewing angles
The viewing angles are measured at CR=10 as below:
Horizontal Left: 80 degrees typ. (M201EW02 V1);
Right:
80 degrees typ. (M201EW02 V1);
Vertical Up: 80 degrees typ. (M201EW02 V1);
Down:
80 degrees typ. (M201EW02 V1);
