AMDGPUPRO Linux- HDMI display without EDID

Hi,

I'm trying to connect small HDMI display 800x480, which not provide EDID information to RX480 card.

Status on HDMI port is "disconnected". I need force HDMI port "on' and force resolution.

With NVIDIA it's easy: (xorg.conf)

In monitor section just add

    Option "ConnectedMonitor" "DFP-1"

    Option "UseEDID" "false"

and

    {viewportout=800x480+0+0}

 

Is there similar option for AMD?

Thanks,

PM
