Part Number: SN75DP159
We have a AMD/Xilinx ZCU106 devkit and inrevium HDMI 2.0 FMC card. Both of them are using the DP159 as the HDMI TX retimer/redriver. With 3840x2160p60 YUV422 12bit format, we found the Samsung TV monitor could not work if connect to Samsung TV monitor's HDMI1 port. But it can work if connect to Samsung TV monitor's HDMI2 port. We verified the Samsung TV monitor's HDMI1 work with other devices' 3840x2160p60 YUV422 12bit output, so the Samsung TV monitor should be good. We also verified the our devkit hdmi tx work with other monitors, so the our devkit hdmi tx also should be good. The problem is the our devkit hdmi tx connect to the Samsung TV monitor's HDMI1 port, the Samsung TV monitor not work(display no signal). We suspect the problem is from DP159 because we use both of ZCU106 or inrevium HDMI 2.0 FMC card have the same problem.
Could you give us some suggestion to process?
