How to transfer video from a smartphone (with microUSB port) to an external portable mini-DISPLAY (AV, HDMI, VGA inputs)?

I'm looking for the best way to transfer the video from a smartphone to an external monitor (used in cars, garages) to get a bigger picture.

1. I find this useful for dash cameras, and for entertainment with bigger display.

May I accomplish this with a OTG cable?

Your help is welcome.
