Customer uses ADV7611 for TV wall design and has an issue for timing detection.


They have problem to get the correct timing information for LINE_WIDTH & FIELD_HEIGHT sometimes. The reported information on ADV7611sometimes has +/- 1~2 pixel/line deviation. They try to change register value HDMI Map; R0x6F from recommended 0x0C to default (leave unchanged after reset) then the problem can be fixed. I can’t find the information for this register, can you please help to check what is this register used for and is there any side effect if customer don’t use the recommended value? Thanks.
