P2715Q - Actually mostly working

I just wanted to report that Brightness Menulet is actually somewhat working with my P2715Q monitors. Contrast adjustment works perfectly, but any attempt to adjust the brightness with the slider simply results in the brightness being set to 100.

Interestingly, if I set the brightness using kfix/ddcctl, the brightness is set correctly and Brightness Menulet is able to read the new brightness value correctly.

Is there any way to make the debug logs more verbose to see exactly what commands Brightness Menulet is trying to send?

I'm not the developer, but I just purchased a P2715Q as well so I'm interested in figuring this out if possible. It looks like the place where the actual command is sent is https://github.com/superduper/BrightnessMenulet/blob/781dde781e0e382b687de90ef57c1b7ee2e8f26c/BrightnessMenulet/ddc.c#L79

If it actually errors, it is logged here: https://github.com/superduper/BrightnessMenulet/blob/master/BrightnessMenulet/DDCControls.m#L45

It doesn't work at all on my P2715Q :/

I'm using https://github.com/florianbeck/BrightnessMenulet with success.
