We’d like to consult about ADV7441 as below:
1. This chip supports VGA input, such as 1024*768. Can the output resolution of be adjusted (lower or higher)?
2. Does the chip support input automatic detection? Like by reading registers to confirm input and input format/Res, and then we can configure the chip accordingly?
1) No, output timing format must be the same as the input timing format
2) Yes, The STDI block and be used to determine timing format. Automatic color space conversion and be set by the PRIM_MODE and VID_STD registers or be overwritten.
Thanks for your feedback. Btw; do we have configuration scripts for some standard input/output format?

Thanks Guenterl. For VGA input with HS/VS not connect; we found STDI_DVALID is not valid; do you have any suggestions? what item we need to check? Many thanks!
