I have couple more questions on ADV7619:
(1) Does the chip defaults to 4:4:4 RGB mode?
(2) If there is any automatic resolution change, while using the chip, any rough estimate of how much software overhead it requires?
Thanking you in advance.
With regards to default configuration, it is important to note that virtually all of our HDMI receivers/transmitters require configuration via I2C. Therefore, it's difficult to talk about what the chip defaults to.
I would suggest you refer to the scripts and the recommended settings document we have posted in the ADV7619 Design Support Files FAQ:
With regards to handling different resolutions, I think there are only a few registers that are different for different resolutions.
