In this article, I’ll explain everything you need to know about HDMI Alt Mode in simple terms.

I’ll cover what it is, how it works, what devices and features it supports, and why you might want to use it.

No technical jargon, I promise! So let’s dive in.

Key Takeaways:

Before we get into the details, here are the main points to remember about HDMI Alt Mode:

  • It lets you connect USB-C devices directly to HDMI displays with a single cable.
  • It supports resolutions up to 4K, surround sound, 3D video, and more.
  • Most newer Android phones, tablets, and laptops work with HDMI Alt Mode.
  • iPhones will likely get USB-C ports and HDMI Alt Mode support by 2024.
  • Connecting by HDMI reduces lag and doesn’t require Wi-Fi compared to wireless.

Got it? Great, now let’s look at each of these points more closely.

What is HDMI Alt Mode?

HDMI Alt Mode (short for Alternate Mode) is a standard that allows HDMI video and audio signals to be sent over a USB-C connection. It turns the USB-C port on your phone or other device into an HDMI port.

This means you can connect your device directly to any HDMI-equipped TV, monitor, projector, etc. using a single USB-C to HDMI cable. No extra adapters or dongles are needed!

HDMI Alt Mode was introduced in 2016 by HDMI Licensing, the group that controls the HDMI specification. It’s built on top of the USB-C standard but is not the same as regular USB. Devices need special chips to support HDMI Alt Mode.

HDMI Alt Mode Is No Longer Being Updated

At CES 2023, HDMI LA (the licensing group) announced that HDMI Alt Mode will no longer be updated with new features. They said there are no more use cases and most devices have switched to DisplayPort Alt Mode instead.

What does this mean for you? Not much, really:

  • Existing devices with HDMI Alt Mode will continue to work fine.
  • You’ll still be able to buy HDMI Alt Mode cables and adapters.
  • Newer devices may not support HDMI Alt Mode, only DisplayPort.
  • DisplayPort Alt Mode offers some benefits over HDMI Alt Mode.

So while HDMI Alt Mode isn’t going away completely, it probably won’t be added to future devices. Let’s look at what you need to use it.

What Do You Need to Use HDMI Alt Mode?

To connect your phone, tablet, or laptop to an HDMI display with HDMI Alt Mode, you need just two things:

  1. A device with a USB-C port that supports HDMI Alt Mode
  2. A USB-C to HDMI cable (or adapter+HDMI cable)

That’s it! As long as your device has the necessary hardware and software support, you can use any standard USB-C to HDMI cable.

The cable plugs into your device’s USB-C port on one end and the display’s HDMI port on the other end.

Some newer USB-C to HDMI cables also support Thunderbolt 3 and 4. These are even faster standards that include USB, DisplayPort, and PCIe. You only need Thunderbolt support if your device specifically requires it.

If you don’t have a USB-C to HDMI cable, you can use a USB-C to HDMI adapter along with a regular HDMI cable.

The adapter plugs into your device and provides a female HDMI port. Make sure the adapter supports 4K if you need that resolution.

So which HDMI features can you use with HDMI Alt Mode? Let’s check out the specs.

HDMI Alt Mode Features

While HDMI Alt Mode doesn’t include all the latest HDMI bells and whistles, it supports most of the essentials from HDMI 1.4b:

Feature Details
Video Resolution Up to 4K (3840×2160)
Audio Formats Up to Dolby 5.1 surround sound
TV Controls HDMI-CEC for remote control
Audio Return Channel ARC for TV audio output
Ethernet HDMI Ethernet Channel (HEC)
3D Video HDMI 1.4b 3D modes

A few things HDMI Alt Mode doesn’t include compared to newer HDMI versions:

  • 4K 60fps – limited to 4K 30fps
  • HDR – no high dynamic range support
  • eARC – only ARC (no high-res audio)
  • ALLM – no auto low latency mode for gaming

Most USB-C to HDMI adapters only support basic video and audio output. To get the full range of HDMI Alt Mode features, you need a certified USB-C to HDMI cable, not just an adapter. Check the specs to see what’s supported.

Next, let’s look at which devices you can use HDMI Alt Mode with.

Devices That Support HDMI Alt Mode

The good news is that most newer devices with USB-C ports support HDMI Alt Mode. This includes:

  • Android phones (Samsung Galaxy, Google Pixel, etc.)
  • Windows laptops and tablets
  • Some Chromebooks and MacBooks
  • Nintendo Switch (in docked mode)

However, there are a few notable exceptions:

  • Apple iPhones and iPads – Lightning port instead of USB-C
  • Some Intel-based MacBooks – Thunderbolt 3 instead of HDMI Alt Mode
  • Older devices with micro-USB or non-Alt Mode USB-C ports

If you’re not sure whether your device supports HDMI Alt Mode, look for the HDMI logo next to the USB-C port or check the specifications. You can also try plugging in a USB-C to HDMI cable and see if it works!

What about iPhones and iPads with Lightning ports? Will those ever get HDMI Alt Mode? Let’s take a look.

Do iPhones Support HDMI Alt Mode?

Right now, iPhones and most iPads use Apple’s proprietary Lightning connector instead of USB-C. So they don’t natively support HDMI Alt Mode.

However, that’s set to change soon thanks to a new European Union law. The EU is requiring all phones and tablets to switch to USB-C charging ports by the end of 2024. They’re even making laptops use USB-C by 2026.

So what does that mean for iPhone users who want to connect to HDMI displays?

  • For now, you need to use Apple’s Lightning Digital AV Adapter or a similar accessory plus an HDMI cable.
  • The adapter only supports up to 1080p HD, not 4K.
  • You can also use AirPlay to mirror your screen wirelessly to an Apple TV or AirPlay 2-compatible smart TV.
  • Future iPhones (likely iPhone 16 in 2024) should have USB-C ports and may support HDMI Alt Mode.

While the switch to USB-C on iPhones is not yet confirmed, it seems very likely. So iPhone users will probably get a simpler, higher-quality wired HDMI connection option within the next couple of years.

Why would you want to connect your phone or laptop to your TV over HDMI instead of wireless casting or a streaming stick? Let’s consider some benefits.

Advantages of Connecting Over HDMI

So you can connect your phone or tablet to your TV wirelessly with Miracast, Chromecast, AirPlay, or a streaming app. You can plug a streaming stick into your TV’s HDMI port. Why bother with a cable? Here are a few reasons:

  • Lower latency for gaming – wireless can have lag.
  • No Wi-Fi needed – works in areas with poor reception.
  • More secure – no data going over the airwaves.
  • Supports TVs without smart features or wireless.
  • Charges your device while connected.

With a wired HDMI connection, you get a stable, high-quality signal with minimal delay. This is important for gaming, but also makes videos and other content look and sound better.

Plus, with HDMI Alt Mode, you can simply plug in a single cable without any extra setup. No pairing devices, entering passwords, or buying a special adapter or dongle. And newer USB-C to HDMI cables can even charge your phone or tablet while it’s connected.

Of course, there are some downsides too. A wired connection means your device is tethered to the TV, so you can’t easily use it for other things at the same time. And you need to have the right cable handy.

Wireless is still more convenient in most cases, especially if you’re just watching YouTube or Netflix. But for the best audio/video quality and responsiveness, HDMI is the way to go.
