Using 10.1" IPS LCD display

I recently purchased one of the non-touch 10.1" displays (<LINK_TEXT text=“ … -2863.html”></LINK_TEXT>), and the control buttons do nothing. When power is applied, it comes on a full brightness, and that’s it. The power button doesn’t turn it on or off, and the increase/decrease brightness buttons also do nothing. I’ve driving it with a Raspberry Pi 3 A+.

Is there some configuration I need to do on the display itself in order to enable the buttons? Any advice would be greatly appreciated.

What as up, just wanted to say, I loved this article. It was funny. Keep on posting free bigtits hardcore!
