Here is my PS4 setup. I put the ps4 slim on the seat beside me because i move it from one car to the other (i replicated the setup of the monitor and power inverter in my other cars).

The headrest monitor is full HD. Its actually a portable LCD monitor that i attached to the headrest via 2 heavy duty Scoche Magnetic mounts.

The monitor is powered by the USB port of the ps4. While the ps4 is powered by the inverter that i have under the seat (1500 watts)
