ADV7619 HDMI PC

Hi, I've made a board with ADV7619 that accepts 2 HDMI input and converts it in LVDS output (24 bit 4:4:4 RGB).

I've tested this board with HDMI input from a uQ7 board and this works perfectly with the script configuration that I found on the design support page.

 

But if I use the HDMI from a PC this doesn't work.

 

Which is the correct script configuration for that input?

 

This is the configuration that I've used
