ADV7604 Hotplug


We are using ADV7604 in our embedded board and we are facing one issue with it.

We have connected PC having DVI-D port to board using DVI-D to DVI-D cable.

If we boot up the board keeping the PC connected to it, ADV7604 chip is unable to detect input source, also

in PC if we see, no display is detected automatically.

If we either press "Detect display" button of graphics card in PC or manually remove and

reconnect DVI cable then ADV7604 can able to detect the input source.

What can i do from software side so that ADV7604 can detect the input source automatically,

without any user interaction.

Thank you in advance.
