DS90UB941AS-Q1: When using the external ref clk of the serializer DS90UB941 with a 15-inch large screen DS90UB948 deserializer, the screen displays abnormally and has water ripple

Tool/software:

For some information, please refer to the ticket below. Our ref clk source is LMK3H0102 clock chip.

In addition, we have two screens. The deserializers are DS90UB948, one 12.9-inch and one 15-inch screen, but the 12.9-inch screen display is normal, and the 15-inch screen display is abnormal. Please help analyze the reasons for the abnormal display of 15-inch screen from the perspectives of DS90UB941 and DS90UB948. Thank you.
