Regarding question #1, the eDP comes enable by default on BIOS.
About question #2 we are checking if we have any information relate to this pin-out you are trying to make. At this point the information we have is on the technical product specification on page 62.
many thanks for your reply.
I have tried different pinouts and also checked the edp lane output on my intel dq77kb with an oscilloscope. but it didnt show any signal.
I really need the advise for intel edp to dp pinout, especially for dp pin 19, 20 which is for power and power_return.
I have also connected the hotplug pin, but no result.
he same dp moniyor works fine when I connec it to normal dp pirt on intel dw77kb.
intel documents on efp is very few please help me to achive this project.
On DQ77KB, eDP shares the LVDS port, so whatever you set LVDS in the BIOS affects eDP as well.
Intel has posted instructions on building an eDP to DP cable in the whitepaper on validating eDP:
http://www.intel.com/content/dam/www/public/us/en/documents/white-papers/validation-methodology-paper.pdf. Refer to pages 12-13 under the section "HW and SW Uniqueness". I believe this is what you are looking for. Let us know if you have any issues accessing the above link.
