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 EU
ROPEAN 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
2.1.1Video signal input
Signal source: pattern generator format as attachment (Table 1 to 34)
Reference generator: QuantumData 802BTThe 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: Single TMDS link (Three channels: RX0-/+, RX1-/+,
RX2-/+).
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 802BT
2.2
Input signal mode
The maximum resolution display of this monitor is up to 1280x1024,
SXGA signal input with full screen display. It shall also automatically
up-scale the lower resolution video modes into 1280x1024 full
screen display. The display capabilities shall include the following
timing modes:
(1) Preset modes (34 modes)
