DK2 HDMI Not Connected Error

Back when I received my CV1 in July I gave my DK2 to my brother in law. He had been using it flawlessly until Christmas. For Christmas I got him a new Gigabyte GTX 1060. We opened his box, installed the new card and updated the drivers. Played a few games on his tv (connected via HDMI to DVI adapter) to check out the increase in FPS from his old GTX 960 2GB. Happy with the new gains we decided to hook the DK2 up and check it out. We connected it directly to the HDMI port, but it would not power up and received HDMI not connected message on OCULUS Home. Then we connected it to the DVI port using an adapter and his TV to the HDMI. Still same error. We then googled some fixes and tried everything we could think of, rolling back drivers to previous version, turning off integrated graphics in BIOS, ect... Finally we decided to re install his old graphics card to see if the DK2 even worked at all. Once it was installed and DK2 connected to his old GTX 960 it ran flawlessly like it always has.

Has anyone else exp something simular? If so what was your fix?

FYI: He has started a ticket with Gigabyte to try and get a replacement card but I dont think the card is faulty. His TV works fine plugged into the HDMI or DVI port. Also going to get another HDMI to DVI adapter and a HDMI to Display Port one and try that.
