Hi,

 

I have a question regarding the maual hotplug assertion. I have enabled manual hotplug using

0x68, 0x6c, 0xA1

 

I have de-asserted the HPA singal using the write

0x98, 0x20, 0x30

 

I have programmed the internal edid with the edid data.

 

I am enabling the HPA by writing

0x98, 0x20, 0xF8

 

However I do not see any hotplug happening. Hotplug will happen only if enable the internal edid active bit to high only.

Is this the correct behaviour?
