DS90UB941AS-Q1: DS90UB941 and DS90UB948 use problems

Part Number: DS90UB941AS-Q1

Hi,Ti

When we used 941 and 948 chips to do the display test, the picture problem as shown in Figure 1 and 2 appeared. Black stripes would appear in the ColorBars mode.
But on the 941 with the 940 there are no graphical issues.
How should this problem be solved?
Do the 941 and 948 chips require any special register configuration?
The videos were the test pictures at 941-948 and 941-940 respectively.
