Technical Data(For 170X7)
1. General
1.1 Product description
170X7 is the 7th generation of Hudson 17" TFT Flat Panel
Display Monitor. The monitor featured with both DVI-D and
analog signal input interface, and modularized as a display unit
with embedded universal AC power supplies inside monitor
main body. The power button and display control buttons (tact
switch type
) are on the front and the right-hand side of the
monitor. The monitor shall support an internal scaler to
automatically enable the monitor to display lower resolution
video modes into 1280 x 1024 full screen display. The image
can be adjusted through OSD control board. These
adjustments can be stored on a board memory including 40
pre-set modes and 19 factory pre-set modes.

1.2.3. Horizontal scan: 30 - 83 KHz
1.2.4. Vertical scan: 56 - 76 Hz
1.2.5. Input signals
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%.
The capability of sync signal inputs shall include separate sync, composite
sync and sync on green. input impedance: 2k2ohms The signals are
defined as follow:
Separate sync TTL level, Positive/Negative
composite sync TTL level, Positive/Negative
Sync on green H-sync TTL level, Positive/Negative
2 ) . Intel DVI Digital
Input signal: Four channel TMDS signals
Signal source: pattern generator format as attachment
(Table 1 to 40 )
