Hey, i have issue with my  AMD RX7900XT. When i connect display to Type-C port display not work and he going in sleep mode.
Оnce i was somehow able to get it to work but it was only until the next reboot.
On first i check display with my phone(as Dex). All is good.
On second i reboot my Windows OS and install Linux base OS and after i install drivers and additional software the situation is same Type-C on GPU not show anything.
My display have USB hub on it and when i connect USB flash drive i see it on OS
DP and HDMI port work.

Is USB-C the same as DisplayPort?

Yes. Just like in standard DisplayPort connectors and cables, DisplayPort over USB-C can take advantage of the four high-speed data lanes in the USB-C connector and cable to provide 4K display resolutions and beyond on supported products.Apr 28, 2023

Also this LinusTechTips Threadabout the same issue as yours: https://linustechtips.com/topic/1502826-no-usb-c-display-output-rx7900xtx/

NOTE: You will need a compatible USB-C adapter cable to connect your Monitor unless your Monitor has a USB-C Input port.

I checked the 2 threads before I even posted, and I'm using a cable you know with the monitor
