You already know that the Nintendo Alarmo can run DOOM, but what about an Apple Lightning to HDMI adapter? The answer to that would be a resounding yes, thanks to a built-in micro chip, similar to a CPU, that takes the output from the iPhone and sends it as HDMI to a TV or other screen with an HDMI input.
That’s right, this dongle is actually a computer, with both Apple Secure Boot and the ability to run Darwin kernel. It also features recovery mode with interactive shell and used to boot kernel cache sent over USB. Why doesn’t Apple make a more basic connector? Well, Lightning isn’t capable of streaming raw HDMI is the primary reason.
- Use the Lightning Digital AV Adapter with your iPhone, iPad, or iPod with Lightning connector.
- The Lightning Digital AV Adapter supports mirroring of what is displayed on your device screen — including apps, presentations, websites,...
- It also outputs video content — movies, TV shows, captured video — to your big screen in up to 1080p HD.

That’s priceless! No wonder they cost so much! TB4 to TB4 cable in the Apple Store is over £120! Got a longer one that does the same thing just as well from Amazon for about £25 or so from Anker or UGreen I recall,” said one commenter.
