D: NSScreen #724058892 (1600x1200 0°) 111.00 DPI I: found 1 external display I: polling display 1's EDID I: got edid.serial: MY5468281HKL I: got edid.name: DELL 2007FP D: action: b: 25 D: setting VCP control #16 => 25

I can set Brightness, Reset, Color profiles OK, but I cannot read any value from the display

D: action: b: ? D: querying VCP control: #16 =? E: No data after 10 tries! E: DDC send command failed! E: VCP control #16 (0x10) = current: 0, max: 0

can it be fixed? Thanks

closed by #31 : probably using a hackintosh -- this is explicitly unsupported.

Feel free to debug on your own, there is a make debug target in the Makefile. ddcctl -D is an undocumented switch that will try to dump all DDC values.

Where can I find the hackintosh explicitly unsupported statement? Please add that info to the readme.

@rdmasio That's in the issue template. Feel free to open a PR ;)

I mean, everything is unsupported really? I don't know how i can nicely make that clear to folks, but I'll try again in the README.
