Sorry, not been on for awhile.
No, I didn't figure it out. Although I went to Apple to talk to the Geniuses. The problem is that every TV connection is different. So, traveling I would have to bring different wires to attach to my computer and their TV. The other thing with wires is the length. If the office doesn't have a counter close by what's going to hold the computer-I-Pad.
SOme customer stated that she travels all over the world and does everything on someone else's TV. I am told that they have to have I-Tunes and other programs on their computer. That won't work for me.
I have a great travel friendly projector (casio) so I am going to stay with that.
I am told soon every TV will have HD and they will all have the same connections -universal- and they will have internet to wirelessly connect. Can't wait.
If you want to airplay from your mac to your apple tv for programs such as Keynote, I beleive that you need to get something similar to AirParrot.
Plug the Apple TV into the TV via HDMI and run your presentation via AirParrot. There is a cable available from Kanex (got mine through Mac1) that coverts the HDMI output from the Apple TV to standard VGA and audio if the TV is too old for HDMI.
I set up the apple tv in the classroom today and tried running a keynote presentation from my iPad.
It starts out great using mirroring, but it just kept timing out, and going back to the apple tv menu. Very frustrating.
I tried turning off the screen saver but it did not help. Anyone have any ideas please.
