Don’t Buy the Wrong USB-C to HDMI Adapter! (Quick Guide)

Need to connect your new laptop to your TV but your laptop only has USB-C ports? Super-frustrating but it’s a very common scenario with many of the newer and sleeker laptop models. This is where a USB-C to HDMI adapter comes in.

In this quick guide, we want to provide everything you need to know to choose the perfect adapter before you buy a USB-C to HDMI adapter.

Get to Know USB-C to HDMI Adapters

What They Are and How They Work

USB-C to HDMI adapters takes the digital signal from your laptop or phone’s USB-C port and transforms it into an HDMI signal. These adapters utilize the “alternate mode” feature of USB-C, which allows the port to output video signals directly. This way, you can display your content on monitors, TVs, and projectors that use HDMI.

Newer USB-C to HDMI adapters are able to support resolutions up to 4K (3840×2160) at a smooth 60Hz refresh rate. If you need even higher performance, some premium models even feature to HDMI 2.1 specifications, unlocking 8K resolution capabilities.

Why Would You Need USB-C to HDMI Adapters?

USB-C to HDMI adapters come in really handy if you frequently encounter the following scenarios:

• Owning a newer laptop with limited ports (common on models like MacBook Air, Dell XPS, or Chromebooks).
• Wanting to mirror or extend your smartphone or tablet display onto a larger screen.
• Needing to deliver presentations on external projectors or monitors.
• Planning to stream movies or other content from your device directly to a television.
• Setting up a multi-monitor workstation for enhanced productivity.

Choosing Your Adapter: What You Need To Consider

Selecting the right USB-C to HDMI adapter means considering a few key technical and physical aspects.

Prioritise Resolution and Refresh Rate

These are perhaps the most crucial technical specifications:

• Resolution Support: While most adapters handle at least 4K (3840×2160), be aware that some budget-friendly options might cap out at 1080p. Ensure the adapter supports the native resolution of your display.
• Refresh Rate: Aim for 60Hz support. Why? Refresh rate indicates how many times per second the image on your screen updates. A 60Hz rate provides noticeably smoother video playback and cursor movement compared to lower rates like 30Hz.
• HDMI Version: HDMI 2.0 is the standard for achieving 4K resolution at 60Hz. For accessing higher resolutions and faster refresh rates (like 8K), you’ll need an adapter that supports the newer HDMI 2.1 specification. These tend to be slightly more costly.

Evaluate Build Quality and Design

Don’t overlook the physical construction – it impacts the cable’s durability and convenience:

• Cable Length: Think about the distance between your device and the display. Choose a length that offers flexibility without excessive slack.
• Materials: Braided nylon cables offer enhanced durability compared to standard plastic. Aluminum housings are better at dissipating heat, preventing overheating during extended use.
• Connector Design: Look for adapters with reinforced connectors. This simple feature helps prevent fraying and damage at the most vulnerable point, extending the adapter’s lifespan.
• Size and Portability: If you travel frequently, a smaller, more compact adapter will be much more convenient to carry.

Ensure Compatibility

Before hitting ‘buy’, double-check these points:

• Your Specific Device Model: Not all USB-C ports support video output; confirm your laptop, tablet, or phone does.
• Your Operating System: Compatibility can sometimes vary slightly between Windows, macOS, Android, and others.
• The Display You Plan to Connect: Verify its supported resolutions and refresh rates to match them with the adapter’s capabilities.

Troubleshooting: Fix Common Adapter Problems

Have you recently bought a USB-C to HDMI adapter and are encountering issues? Here are some solutions to typical problems:

Connection Problems

If your display isn’t detecting a signal:

• Verify Device Support: Ensure your laptop, tablet, or phone actually supports video output over its USB-C port / DP Alt Mode.
• Swap HDMI Cables: A faulty HDMI cable is a common culprit. Try a different, known-working one.
• Check for Drivers: See if your specific adapter model requires any special driver installation.
• Simply Restart: Sometimes, a quick restart of both your source device and the display can resolve connection glitches.

Display Quality Issues

Dealing with incorrect resolution or refresh rates:

• Confirm Display Compatibility: Make sure your monitor or TV is capable of displaying the resolution and refresh rate you’re attempting to send.
• Review Adapter Specs: Double-check the adapter’s specifications to confirm it explicitly supports your desired resolution and refresh rate (e.g., 4K@60Hz).
• Update Drivers: Ensure your device’s graphics drivers are up to date.
• Adjust Display Settings: Experiment with different display settings within your device’s operating system.

Overheating

It is normal for adapters to get warm, but excessive heat is a problem:

• Choose Aluminum: Opt for adapters with aluminum housings, as they are far better at dissipating heat than plastic ones.
• Avoid Hot Environments: Don’t use the adapter in direct sunlight or confined, high-temperature spaces for extended periods.
• Ensure Ventilation: Make sure the adapter has space to breathe and isn’t covered or trapped, allowing for proper airflow.

Pick the Perfect Adapter for Your Purpose

Your ideal adapter depends heavily on how you plan to use it.

For Business Professionals

If you’re constantly on the go, giving presentations or working from various locations:

• Prioritise Portability and Durability: Choose a compact adapter built to withstand frequent travel.
• Consider Multi-Port Docks: Instead of a simple adapter, docks with additional ports offer greater versatility for connecting peripheral devices during presentations.
• Look for Accessories: Some adapters even come with carrying cases or pouches for added convenience and protection.

For Home Entertainment

If your primary goal is streaming movies or shows to your TV:

• Focus on 4K@60Hz: This specification is crucial for the best possible viewing experience with smooth, high-resolution video.
• Think About Cable Length: Longer cables provide more flexibility in positioning your device relative to the TV.
• Check for HDR Support: If your TV supports High Dynamic Range (HDR), look for an adapter that passes through this signal for enhanced colour and contrast (note: source mentions HDR but not specifically for these adapters).

Final Thoughts

You can use a USB-C to HDMI adapter to connect your device that only has USB-C ports to a TV or monitor that doesn’t have a USB-C port but has a HDMI port. One important point that I didn’t mention earlier is that you will need to get your own HDMI cable. Alternatively, you could use a USB-C to HDMI cable to connect the devices directly. Check out the linked article if you’d like to know more.

The adapters listed above can all do 4k@60Hz, which is pretty good for watching content. Newer adapters can even do 8K but they cost more.

As I mentioned earlier, you need to make sure that your output device can do DP Alt Mode, which allows it to transmit video signals through the USB-C port. Not all devices can!
