So I didn't really have a workflow plan and list of things to display so this has been total trial and error. What I found is that once I displayed a couple student presentations more and more students have asked to have their worked "streamed" in the big screens.
*Stream from Apple TV. (Our internet/filter/etc. does not play nice with Apple TV.)
*Stream from Chromecast. (Streams a little better on our platform but you need computer specifically for mirroring and a trained person to monitor it all day. Loses connection? Who troubleshoots?)
*Image slide show on USB! Ba-Bam! This has worked so far.
*If just displaying pictures, I put on USB and plug into TV, DONE.
*Teachers share their own Google presentations or share student Google presentations.
*I download as PPT, save as pictures, put pics on USB, DONE. I don't have to worry about connection issues all day.
Student presentations are the best! Tomorrow I am combining 4 student presentations as a slideshow to stream next week!
What's your TV display workflow?
