2.1.2 Display format

The LC1200R is compatible with IBM VGA1 and VESA2 video standards. Its operating frequency range is 31.5 kHz to 56.5 kHz horizontal; 60 Hz to 72 Hz (non-interlaced) vertical. Specific video resolutions supported in Table 1

For IBM VGA1 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 VESA2 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 VGA1 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.
