1.
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 39) Reference generator: QuantumData
802G
The input signals can be applied in two different
modes:
1). VESA Analog
The video input consists of red, green, and blue
signals. The video signals
are analog levels, where 0V corresponds to black
and 700mV is the maximum
signal amplitude. Input impedance of video pins is
75 ohm +/- 1%.
2). Intel DVI Digital
Input signal: Four channel TMDS signals
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
Thesignalare defined as follow:
Separate sync
Composite sync
Sync on green H-sync
Signal source: pattern generator format as attachment
(Table 1 to 39)
Reference generator: QuantumData 802G

Remark1: The 19 timing modes in
Factory Preset modes
which need to be ensured perfect performance.
Remark2: Other modes can pass with fair performance.
Remark3: If 1280x720 and 960x720 can not be distinguished then
1280x720 is preferred.
Remark4: If 1280x768 and 1024x768 can not be distinguished
.
then 1024x768 is preferred
