To tie things together a bit on this bug report.
On the ddcutil front I have discovered that if the monitor is powered down and
the HDMI cable unplugged when the laptop is booted, and the monitor then
powered on and connected, it claims to support DDC/CI.
If, however, the monitor is in standby mode and connected when powering up the
laptop, it claims not to support DDC/CI.
Bug report with ddcutil here: https://github.com/rockowitz/ddcutil/issues/476
However, no matter if DDC/CI is supported, the monitor does not wake up
properly from sleep.
This is making me think that the DDC/CI support is a separate driver issue:
Filed a topic in the nVidia forum on this:
https://forums.developer.nvidia.com/t/external-monitor-inconsistent-ddc-ci-detection/316597
However, the original issue still remains on this laptop, which is that the
monitor does not wake up properly when frame rates over 30Hz is selected.
Hoping that this might be a driver issue as well, I filed a separate topic on
this on the nVidia forums:
