About 1&1/2 years ago I got the 7 inch touchscreen, and i really liked it. in fact im using it to put this on forum now. but just recently i tried to plug it into the hdmi tv again(the pi 3) but it didnt give a video output. this used to work, even after i had used the touchscreen, but now the pi boots up properly, but it doesnt give hdmi output. I know i can just edit the hdmi-force-hotplug thingy in config.txt, but i still want to use the touchscreen after, and i was wondering if there was a non-permanent way to make it work, like to work with both the official touchscreen and the tv/monitor. so is there any way I can make my pi3 running the latest raspbian stretch release(the one with the edited file explorer interface) work with both screens(not simultaneously)?
