I have questions regarding the Table 7 in the ADV7612 Hardware User Guide.
We need to support the following input formats:
1600 x 1200 Progressive 60Hz
1280 x 1024 Progressive 60Hz
1024 x 768 Progressive 60Hz
1920 x 1080 Progressive 60Hz
1920 x 1080 Interlaced 50Hz
1920 x 1080 Interlaced 60Hz
1280 x 720 Progressive 50Hz
1280 x 720 Progressive 60Hz
With a 1024x768 input source and PRIM_MODE=0x5, VID_STD=0x13 our image had "color bleed" and "dark Shadows". It cleared up when we set PRIM_MODE=0x6 and VID_STD=0x0C (as described in Table 7).
1) Did this problem occur because we were programed for HDMI-COMP when were were using a HDMI-GR input video?
2) Can the ADV7612 be programed to auto detect these different formats or do I have to program it differently for each?
3) Input format 1600 x 1200 is absent from Table 7 and has only a vague reference in the entire document. Is this resolution supported? Is there any special register settings needed?
Thanks for the help,
