[FEATURE] Support of DP to HDMI convertor
I prefer DP interfaces, but the lack of large monitors with high frequency made me buy 55" LG OLED55C11, supports 120hz refresh rate, but lack any DP. So I bought DP to HDMI adapters:
- https://www.amazon.com/CLUB-3D-CAC-1082-Active-Adapter/dp/B07HNTNTMR
- https://www.amazon.com/Club-3D-DisplayPort1-4-Adapter-CAC-1085/dp/B08BX49V5V for the second one I don't have USB-C port A power yet, waiting for additional pci-express card, it displays, but maybe lack enough power, don't know.
I use it with nvidia 1030 gt which has one do and one hdmi.
So when using the first dp-hdmi adapter, I can get only following 60hz instead of 120hz supported by the panel, I copy full output on dual screen display, the feature request is related to first DP-0 monitor, the secondary monitor connected via HDMI-0 is older PHilips which is limited to 60hz where I see only 30hz, so its also issue from my perspective. For the hdmi I use https://www.amazon.com/High-Speed-Cable-Style-20276/dp/B076G4MKQ1 cable.

Is it possible to make xrandr work via these interface adapters to report correct values? I tried to enforce xrandr to manually configure 120hz at 4k, but it didn't work.
