1. General
1.1 Product description
170X6 is the 6th 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 34 pre-set
modes and 16 factory pre-set modes.

Note :
To achieve under 1 Watt power saving when Stand-Alone Audio
feature is selected On and system is in Sleep Mode, follow below
condition :
Volume has to be adjusted to 0% prior to measurement.
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: 2k2 ohms
The signals are defined as follow:
Separate sync
Composite sync TTL level, Positive/Negative
Sync on green H-sync TTL level, Positive/Negative
