ADV7441 Input Res Detect and Output Res adjust

Hello;

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?

Many thanks;

Bell
