General points
1.1 During the test and measuring, supply a distortion free AC mains
voltage to the apparatus via an isolated transformer with low internal
resistance.
1.2 All measurements mentioned hereafter are carried out at a normal
mains voltage (90 - 132 VAC for USA version, 195 -264 VAC for
EUROPEAN version, or 90 - 264 VAC for the model with full range
power supply, unless otherwise stated.)
1.3 All voltages are to be measured or applied with respect to
ground, unless otherwise stated.
Note: don't use heat-sink as ground.
1.4 The test has to be done on a complete set including LCD panel
after 30 minutes warm-up at least in a room with temperature of
25 +/- 5 degree C.
1.5
All values mentioned in these test instruction are only
applicable of a well aligned apparatus, with correct signal.
1.6
The letters symbols (B) and (S) placed behind the test
instruction denotes
(B): carried out 100% inspection at assembly line
(S): carried out test by sampling
1.7
The white balance (color temperature) has to be tested in
subdued lighted room.
1.8
Repetitive power on / off cycle are allowed except it should
be avoided within 6 sec.

Input signal
2.1
Signal type
2.1.1 Video signal input
Signal source: pattern generator format as attachment.
(Table 1 to 34)
Reference generator: QuantumData 802G
The input signals can be applied via VESA analog:
The video input consists of red, green, and blue signals. The
video signals are analog
and 700mV is the maximum signal amplitude. Input impedance
of video pins is 75 ohm +/- 1%.
2.1.2 Sync signal input
The capability of sync signal inputs shall include separate sync,
composite sync and sync on green. input impedance: 2k2 ohms
The signals are defined as follow:
Separate sync
Composite sync
Sync on green H-sync
Signal source: pattern generator format as attachment (Table 1 to 34)
Reference generator: QuantumData 802G

Allowed 85 Hz overscan signal mode specified
Once the signal input of PC is 85Hz, this monitor is able to
display at least for10 minutes. An attention signal appears and
shows "This is 85Hz overscan for 5 seconds, change computer
display input to 1280*1024 @ 60 Hz "
