or a non-pro iPad, youll need Apples Lightning-HDMI Feb 9. The Apple Lightning to HDMI adapter allows you to mirror the screen of your iPad, iPhone or iPod touch on an HDMI-equipped TV, display, projector or other.
LIGHTNING TO HDMI TV
"If the lightning cable is their solution for the foreseeable future, don't hold your breath on putting that retina iPad full-resolution on your 4K TV in a few years.

Stanfill, who has extensive experience with AirPlay, told us that he " believe that the AirPlay itself is being used here, it certainly seems like the underlying hardware that powers AirPlay mirroring is being used for the AV Lightning adapter." Stanfill concurs that this "also explains the limited resolution support - keeping costs down and performance up means the higher h264 levels needed to support more pixels likely aren't supported by the SoC employed in the adapter." The HDMI Alternate Mode lets you project video and play audio on an external display that supports HDMI. The information coming from this anonymous source lines up pretty closely with what we've been told by David Stanfill, founder of AirParrot and Reflector developer Napkin Studio. The Lightning Digital AV Adapter supports mirroring of what is displayed on your device screen - including apps, presentations, websites, slideshows, and more. Apple engineers are apparently aware that the current implementation leaves something to be desired since it introduces lag and compression artifacts, but the adapter's firmware is supposedly upgradeable and improvements will evidently be made to the compression in future iOS updates.īy subscribing, you are agreeing to Engadget's Terms and Privacy Policy. This setup is apparently future-proof according to the poster, since it's entirely software-driven. The encoded data is transferred as packetized data across the Lightning bus, where it is decoded by the ARM SoC and pushed out over HDMI. Airplay itself (the network protocol) is NOT involved in this process.
What happens here is that we use the same hardware to encode an output stream on the fly and fire it down the Lightning cable straight into the ARM SoC the guys at Panic discovered. Posting to Slashdot, the anonymous individual claims that AirPlay isn't actually being used at all, and that contrary to some speculation the adapter's processor doesn't run a stripped-down version of iOS: They had some thoughts on how the accessory might be working its magic, namely that it could be using AirPlay in some way, but now someone claiming to be an Apple engineer has come forward with what's said to be the official explanation of how it works.
To their surprise, they found that it contained a tiny computer featuring an ARM processor and 256 MB of memory.
LIGHTNING TO HDMI 1080P
Last week, we shared how the folks at Panic had pulled apart one of Apple's Lightning to HDMI digital AV adapters in an attempt to figure out why it didn't seem to output true 1080p HD video.
