1. General
1.1.Product description
The Hudson3 23"TFT flat panel monitor is specified as a display
peripheral with Analog video signal input, Digital video input , CVBS ,
S-video input and YPbPr video input. Horizontal scan range is
30 - 94 KHz and refresh range is 56 - 85 Hz. This scan range
allows it to display resolution up to 1920*1200 non-interlaced at
60 Hz refresh rate. The image can be adjust through OSD control,
these adjustments can be stored on an board memory including 42
preset modes and 20 factory preset modes. All optical
characteristics (including WHITE-D, brightness, and so on) are Pin No. Description
