Hi there:
I am using debian 11 linux with a macbook pro 2013 15-inch. i7-3740QM CPU (NIVIDIA-GPU switch)
I think on my macbook pro the HDMI port with external monitor is not working while the DP port /thunderbolt 2 is working. (Actually one of my 2 DP port is working the other is not) These three ports work under MacOS system:

Many users met similar issues: HDMI got detected by xrandr while the external monitor got no signals. Could you help us?
Attached the nvidia-bug-report.log.gz which shows : "No NUMA configuration found" https://forums.developer.nvidia.com/t/no-signal-with-hdmi-or-dp-0-ports-on-m...
