MacBook contrast cannot be adjusted
I have a MacBook 13.2.1 Ventura. It has the M1 chip. The screen contrast is too bright and I'm trying to set it to a lower contrast. I noticed that the buttons or sliders that should be there to adjust contrast, etc. are not there. they have disappeared. I am now stuck with a very high contrast and cannot see everything properly. Any thoughts?
