Forum Question: How can I display a Keynote presentation wirelessly?

Does anyone know of a wireless link to transmit video from a Mac to a projector? I’ve seen a few for Windows PCs, but nothing for Mac.

    You could get a projector that takes HDMI, and then use a $99 Apple TV, connect that to the projector. Then use AirPlay to stream the video from your Mac to the Apple TV.
    I’ve never used one, but I also believe there are wireless VGA cables. Get one of those and do it that way.

      Problem is we’ve already spent $700 on a projector, but it doesn’t have an HDMI port. I have seen the wireless VGA receivers for plugging into the projectors, but all the transmitters are USB and say they’re for Windows. I realize that just because they don’t say “Mac” doesn’t mean they won’t work on a Mac, but I’ve never heard of presenting Keynote over USB, so I’m hesitant to order it without confirmation from someone who’s successfully used it with Mac.

    Can Keynote presentations be streamed over an Apple TV, advancing slides from the Mac in real time?

      Ah, in the original post you said “video” not “Keynote.”
      No, Keynote does not work with AirPlay. Yet. Rumors that the next version will, but just rumors.
      You could always export a video from Keynote and use that, with pauses.
      So, why not just have a long VGA cable? I know you want to do wireless, but there just doesn’t seem to be a solution. I’ve run a 100 foot VGA cable before. I’d imagine that further than that and a wireless signal with all that data would start to suffer anyway.

    I guess I should clarify further. The projector is in a church, hanging from the ceiling directly over the pulpit. Running VGA straight up would be unattractive, and while I could run it under the platform and up the wall, the projector is already connected to an iMac in the back of the church via a 100′ VGA cable that runs through the ceiling. I need a way to switch seamless between the iMac in the sound booth in the back and my MBA at the pulpit. I was thinking if I could establish a wireless VGA connection with my MBA, I could switch the iMac to a different input on the projector using a VGA-to-Composite or S-video converter. That way, all I would need to do is use the projector’s remote to switch to a different source input. My biggest hurdle to accomplishing this goal is finding a Mac-compatible solution to transmit the Keynote presentation wirelessly from my MBA at the pulpit.

      So the projector is already connected to an iMac? The solution is simple, then. Use Screen Sharing to connect the MacBook to the iMac. So the presentation is running on the iMac. But you are controlling the iMac from the MacBook.

        That’s what I’m currently doing, but because the screen sharing window is so wide due to including the current slide, next slide and slide projection, I can only enlarge it slightly. And on an 11″ screen, this makes my slide notes virtually unreadable, because they’re so tiny. By running directly from my MBA, I was hoping to maximize screen real estate.

    This is a nice and cheap solution, only £30. The resolution is 1024, so it’s not HD (which is what I’m looking for), you can get the same make, a model higher, but the price goes over £100 then (but if you have the money it’s good). The only thing I’m not sure about is the range, testing the range of wireless by creating a wifi hotspot on my MacBook Pro, then using the KeyNote remote app on my iphone, I was about to get about 27 strides from my laptop before it stops responding. It’s hard to say exactly how far that is, but it was the length of a decent sized hall. I’m also 6″2 so each stride was fairly far :P Hope that helps.
