I do Media for Landmark Church on many Sundays (video, projection, etc). Today, due to a well-meaning volunteer updating software on a device, we had some equipment issues.
The confidence/stage displays (for speakers, singers, etc) would not work properly. So with minutes to spare, we managed to use a 50’ HDMI run with a TV stolen from the green room with an iPad and a mirroring app to have a functioning set up by go time.
It looked professionally installed from the stage and audience. But from behind it looked like a tornado ripped through a spider web. Oh well. It worked for the day.
