Can FORCE_VIDEO be used to generate a test pattern on the MAX9281?
The FORCE_VIDEO bit in register 0x95 is a way to mask video coming into the serializer with some known value, i.e. a blue screen. You need valid sync signals (HS, VS, DE) and PCLK in order for the serializer to send video data specified by DFORCE in registers 0x9D-0x9F. So, you can generate a solid color with the DFORCE bits, but that color will only be transmitted when PCLK and valid sync signals are present.
