Hello! Can you please help? Tell me how to switch 3.3v 5v 12v.

I connect 12v to the dc input. On 1 2 3 vcc contacts of lvds I see 3.3v. And this is suitable for the laptop display. What should I do to get 5v or 12v on contacts 1, 2, 3 of the LVDS?

There is no 5V voltage on the board. The default voltages on the board are 3V3 and 1V8

Maybe this schematic can help you

If you want to connect other power sources, you can remove this transistor and then jumper to select other power input
