No video output using DP to HDMI cable, require nomodeset or amdgpu.dc

I installed Arch on HP EliteDesk 705 G3 Mini, I am trying to connect it to my projector with a HDMI input however the PC only has DP ports. The system can connect to DP just fine.
I have a DP to HDMI cable which worked in Windows but doesnt with Arch, I found that adding nomodeset or amdgpu.dc=0.

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855

What "doesn't work" and how?
Do you still have console output and only X11 fails?
At what resolution are you trying to drive the projector?

Are there any errors in the system journal?

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

to post the one of the previous boot.

If it's (only) X11, please post your Xorg log, https://wiki.archlinux.org/title/Xorg#General
