I’m trying to use the HDMI 2.0 “Plugable Active DisplayPort to HDMI Adapter” (full size Displayport version) to connect my PC to my receiver. This is with windows 10, an Nvidia 2080ti, and a Yamaha RX-V777BT. Connecting directly from the graphics card to my receiver works fine with the HDMI port on my graphics card, all channels show up, all frequencies and bit depths function properly, 44khz-192khz, 16bit and 24bit.
With the same cables and the same port on the receiver with your adapter I only have stereo 16bit 48khz available. Even using a vertex between them to emulate a different edid does nothing. I did get it to partially work before using “Custom Resolution Utility” and editing into the edid 5.1 manually, this did allow me to select 5.1, however even at the time that worked anything over 48khz would put no actual audio out to my speakers. This is also not reliable through any changes to my setup.
Another issue is I don’t seem to be able to select YUV 4:4:4 nor RGB Full, just RGB limited, both are selectable with a direct connection, while less important than the audio issue it would be nice to find a solution to this as well.
Is there a firmware update available for me to try?
