I have a question about the ADV7513 HDMI differential output amplitude. Is there a registers/ hidden registers on the ADV7153 that could control the driver output amplitude of the HDMI channel 0 to 2 and clock driver? I look through the programming guide document of the ADV7513 and it does not listed a register to control that. The customer complaints the output amplitude of the HDMI signal and want to tune it down to match with the HDMI port 1 and port2 amplitude that output from Nvidia SOM.
Looking forward for your reply
