For IBM VGA
1
modes, the LC1200R will accept 640 pixels horizontally; 400 or 480 lines
vertically and 800 pixels or 1024 pixels horizontally, 600 lines or 768 lines vertically for the
VESA
2
modes. Figure 4 defines the video signal timing requirements.
The LCD controller board will automatically program itself, sensing incoming
horizontal/vertical frequencies and sync pulse polarities to completely “fill” the active display
area of the LC1200R with the video resolution being presented. Section 4.2 defines
parameters for video resolution detection by the LCD controller board.
Note: IBM VGA
1
modes with border and the 720 x 400 video resolutions are excluded from
completely filling the active display area horizontally. Only the first 640 pixels will be
displayed.
2.2 Weight
The LC1200R has a lightweight aluminum enclosure and does not exceed 1.8 kg (4 lbs)
