I assume you're referring to the proprietary Nvidia driver. Yes, its I2C support is problematic. I assume you've seen the Nvidia page http://www.ddcutil.com/nvidia/ on the website. Note the recent addition courtesy of user arcnnmx about the need to put settings in /etc/modprobe.conf or /etc/modprobe.d/something.conf. The only thing I would add is that I seem to be having better luck with DisplayPort connected devices, which emulate I2C over the Aux channel.

Tried almost everything on multiple displays. Seems like Nvidia/Pascal just doesn't support DDC although once a couple years ago it worked for a day. Since then I've spent hours and nothing.

Thanks for responding. After addind modprobe I actually have ddcutil working on HDMI. For some reason gddccontrol won't work although the i2c is clearly working. For now I will stick with ddcutil, thanks!
