ADV7842 input signal resolution detection

I am using the ADV7842 chip on a project that has a VGA input and DVI input.

Is there a way to auto-detect or read a register to know what the input signal resolution is 640x480, 800x600, or 1024x768?

 

I am able to run i2c sequences to get all of these resolutions to work successfully (on both VGA and DVI inputs) - but, I have to manually select the sequences in the code.
