DS90UB941AS-Q1: DS90UB941AS-Q1

Our 941 application is shown in the following figure, using one DSI0 output to 941 ，941output two FPDLINK to 948，948 output two LVDS with a resolution of 1920* 1080P@60Hz Display screen.

The I2C register configurations for 941 and 948 are as follows：

The current problem is that the display screen is blurry and flickering. Please ask TI's engineers to help analyze the cause. Thank you
