      I am developing a project of a portable game, which can be connected to the TV. I want to make a retro game like a Nintendo Switch, which I can switch from laptop to desktop.
      But I have two problems:
      1- I'm using a car camera screen with a composite video input. For the image to look good, I had to change the resolution (config file) setting to the resolution of the 480x360. However, my TV is already HD. So, when I turn the console on the TV, the image gets small on the screen.
      2- Every time I switch from the small screen to the TV, I need to restart the console so that it identifies the video connection exchange. Since the small screen uses AV and the TV uses HDMI.
      My doubts are:
      1 - Is there any way to change the configuration file to increase or decrease automatically when switching from the portable screen to the TV?
      2 - Is there a way to change video output without turning RPI off?
      I'm using an RPI 3.
      Thank you.

        @victornmartins Resolution cannot be changed on the fly. The resolution / output mode is determined by the settings in /boot/config.txt as you obviously know, These settings are loaded on boot and it takes a reboot to reload any changes made.
        Sorry but what you are proposing is just not possible.
