is this supposed to work with displayport -> hdmi -> tv ?

it's a vizio tv that supports only CEC. not sure about DDC.

it seems literally impossible to control the volume of my tv without a remote.

the volume bar moved but it doesn't adjust the volume...

Thanks, it works in Sierra; however, the F11 key doesn't work to decrease volume.
F10 key - mute volume : OK.
F12 key - increase volume: OK.
F11 key - decrease volume: does not work.

Thanks a lot, works great in Sierra for me, also F11.

It works in 10.12.1~10.12.6
My VGA= GTX1060 and another PC is GTX950
through hdmi port
it works perfect!

ddcctl is just a command line executable. You can use it with an app like OSDisplay.app to give it a UI.

DDCCTL is an app that includes a UI.

Hello

Just tried it on a 10.12.6 rig with a DP monitor (not HDMI)
The UI seems to work as intended. F10-F12 keys move the audio slider according to what is expected. However, this has absolutely no effect on the output volume (it remains constant as defined by the monitor, I guess).

Any advice is welcome.

Best,

PS: monitor = Dell S2817Q

I will give these free solutions a try

1) (demo version is free forever and apparently does the job):

2) (controls via app or keyboard shortcuts, not via dedicated apple keyboard keys: F10-F12)https://www.tonymacx86.com/threads/a-small-utility-to-adjust-hdmi-and-displayport-volume.229156/
