I have a question about configuring the ADV7842 to process a graphics input.
This question is regarding a graphics input over DVI/HDMI. In the HW Manual, Section 4 ("Primary Mode and Video Standard"), there is a PRIM_MODE setting for HDMI-Graphics (0x6), but the corresponding VID_STD settings shown in Table-3 only cover resolutions up to 1024x768. What VID_STD settings do I use for larger resolutions like 1600x1200 or 1920x1200 (or any other formats with a pixel clock of 165 MHz or less).
Even for RGB-Graphics, many formats are not listed. How do I configure the device for unlisted formats? For example, say I want to capture 800x600 @ 120 fps (reduced blanking), pixel-clock = 73.25 MHz? The HW Manual says the device supports formats with pixel clocks less than 170 MHz so this should be possible.
