Samsung C24FG70 only detected on DP and not HDMI #221

I've attached the interrogation. If I'm right the HDMI is i2c-6 in the hdmi log. It's i2c-9 in the displayport log. There's some sort of response on i2c-6 but i'm guessing it's not what it's expecting. I recently switched from Windows and I used to be able to control the brightness there so I know it supports it. Let me know if there's anything else I can do to help get this fixed. ddcutil_hdmi.log ddcutil_displayport.log

You do not appear to be using the special settings often needed by the proprietary Nvidia driver.

Also, there have been problems with recent Nvidia drivers. (See #201) If the special settings dont' work, try dropping back to an earlier dirver (e.g. 460 series).

Thanks, I’ll give it a go later. The output from ddcutil environment made it seem like I didn’t need to use based on what it said so I didn’t bother.

I gave both the settings in xorg.conf and modprobe.d folder a try and it's not showing up in /proc/driver/nvidia/params. Not sure what else to do aside from trying an earlier driver.
