DS90UB949-Q1EVM: How to modify the partner information to DS90UB940 and why the hdmi input is not corrent ?

Hi, team. I have troubles when using the DS90UB949-Q1EVM board.

I select the DS90UB949 profile and LaunchPAD can read the DS90UB949's registers and all jumpers and switches are in correct status  according to the user's guide. 

• Trouble 1:

As you see in Figure 1, the default partner is DS90UH926 for the profile DS90UB949, and we use the deserializer DS90UB940, so I need to modify the partner information, but I don't know how to 

modify it.

• Trouble 2

I  connect the PC host to EVM board by HDMI port, and PC output 1920*1080@60, but the HDMI tab display as Figure 2. (I output the hdmi video to another PC monitor and the display is OK).

Thank you very much!
