A:AnswerI don't know for sure, but I don't see why not. Your tv port should recognize your camera. I haven't tried it (nor thought about it), but now that I have, I may use it in the future.
A:AnswerThat I don't know, I would suggest you bring your iMac to the store and compare the plug to your device. I have been searching for a HDMI to micro male
A:AnswerYes - as long as the laptop has the mini displayport jack and the projector has an HDMI input it will work fine. We use these in conference rooms now - mostly to connect to large TVs but I have used them connected to a projector with an HDMI input.
A:AnswerUnfortunately no, neither of those devices likely has an HDMI port on it. If you are trying to transfer pictures between them you will likely need a USB cable.
A:AnswerNo, this Thunderbolt to HDMI cable is for MacBook to connect TV or monitor with HDMI input. You will need a lighting to HDMI adaptor to connect your iPhone to TV.
A:AnswerThis is what I used to connect my 2011 MacBook Pro through HDMI to my TV. I took my laptop to the store to try out the adaptor cord there and it worked just fine.
