Hi,

Also, is the source a DP++ source? The schematic has the net name of DVI, so I want to make sure if the source is a DP++ AC coupled or DVI DC coupled source.

Thanks

David

Hi David

The GPU is INTEL Coffee Lake Refresh- H CPU, and the output is DVI/HDMI signal.

Thanks

Hi,

If the Intel Coffee Lake Refresh-H CPU output is DVI/HDMI, then you want to replace the TDP0604 input capacitors with 0-ohm resistor since DVI/HDMI is a DC-coupled interface.

Thanks

David

HI David

Thank you so much for your clarification..

Thanks.

HI David

Modify the schematic for the input capacitor with a 0 ohm resistor.
please see Attachment...

question:
Regarding the setting of the pull-up/pull-down resistor of TDP0604, is my current definition correct?
