Describe the issue

I use monitor control on a macmini m2 with an apple led cinema display. I'm Very happy to be able to control brightness and volume.
But, I have to start up the application every time I start up the computer, I have clicked -the start up after login- box in preferences several times but after starting up it's empty
And the contrast control does not work. the slider is working in the menu but does not change contrast.

Can anyone help me with this,
Ce.

Expected behavior

The programme to automatically start up.
and the contrast control slider to work
Thank you

Anything else?
