Other Parts Discussed in Thread: TUSB1064, TUSB1064RNQEVM, TUSB564
Using the TPS65987D to negotiate USB PD Alt mode with a TUSB1064 to switch the signals i have been able to get alt mode with a Display port to Display port cable to a monitor. I have tried to use three different DP to HDMI converters and none of them will allow Display capabilities. i have verified that the HPD signal toggles, that the dp connector has 3.3v. I verified with a docking station that the converter works with the s20 device. I am not sure what else to check to solve this problem. I have attached the pd negotiation and a couple pictures of the schematic and the config of the pd controller.
