Acer Understanding Monitor Electrical Requirements and Test Conditions

Electrical Requirements of G195HQ

Standard Test Conditions

All tests shall be performed under the following conditions, unless otherwise specified.

Warm up time	＞ 30 min.
AC supply voltage	220V± 5％, 50± 3 Hz
Ambient temperature	20°C ± 5°C
Humidity	50% ± 10%
Display mode	1366 x 768, 60 Hz, all white
e-color mode	Set to “User” mode
Contrast control	Set to The value under user mode, which allows that the brightest
	two of 32 linear distributed gray-scales (0 ～ 700mv) can be
	distinguished.
Color temperature	6500°K
Brightness control	The value under user mode
Analog Input signal	700 mVss
Picture position and size	Factory preset value,
Viewing angle	90 ° H and V
Viewing distance	40 cm for LCD performance, 20 cm for LCD failures
Ambient illumination	Dark room < 1 cd/m2

Measurement systems

The units of measure stated in this document are listed below: 1 gamma = 1 nano tesla

1 tesla = 10,000 gauss cm = in x 2.54

Lb = kg x 2.2

Degrees F = [°C x 1.8] + 32 Degrees C = [°F - 32]/1.8 u' = 4x/(-2x + 12y + 3)

v' = 9y/(-2x + 12y + 3)

x = (27u'/4)/[(9u'/2) - 12v' + 9] y = (3v')/[(9u'/2) - 12v' + 9] nits = cd/(m2) = Ft-L x 3.426 lux = foot-candle x 10.76
