DS90UH949-Q1EVM: Could I change and detect the Active video of HDMI input?

Part Number: DS90UH949-Q1EVM

Dears:

We are debugging the EVM and find the EVM only detected  Active video is only 1280x720 whatever we inut.

From the below picture, we have only detected Active video is 1280x720 and HDMI Freq is 74MHz.

From the below picture we can see our setting from the PC notebook.

From the below picture we tried to set the Video Control, however the detected result is only 1280x720.

Is there any other setting need we to pay attention?

Pls. give some advice, thanks a lot!

Best regards
