HI .Experts
Ds90ub960 is connected with two dsub953 1080p 30fps cameras. If the register configuration of ds90ub960 0x20 is E0, the input of the first camera is normal. If the ds90ub960 0x20 register is configured as d0, the second channel camera is also normal. , if only one channel is used, each channel is normal. However, if the 0x20 register is configured to C0, there is no output.
Here is my 960 configuration: Is the following configuration correct? How can I find the problem?
