See my response to issue #307. As far as I can tell, the Designware HDMI driver does not support DDC/CI. Also, from what little documentation I've found on the monitor,...

First, please submit the output of **sudo ddcutil interrogate** as an attachment. It shortcuts lots of back and forth with specific questions. Since you're building from GitHub, please build from...
Frankly, I'm at a loss as to what to suggest. First, that ddcutil works with the PB277 indicates that the problem is not with ddcutil. The error code I'm seeing...
Starting with ddcutil 1.0.0, libddcutil numbering has followed the standard Linux convention, and is implemented using libtool. The major version is incremented for non-upwardly compatible changes. The minor version is...
I apologize for taking so long to answer your question. I needed to refresh my understanding of PowerDevil. I looked at PowerDevil in late 2021 because of an assert() failure...
It's not so much that it's bad, it may not be useful depending on how your GUI is structured. Verification is expensive, entailing a sleep to read the value as...
