📌 Quick Takeaways

Last week, a friend of mine spent an hour trying to cast his Huawei P60 to a hotel TV. He tapped every button, enabled every setting—still nothing. Turns out, he just needed to toggle “Wireless projection” in the quick settings, but the interface had moved in HarmonyOS 3. That’s why I’m writing this – to save you from that same black-screen headache.

I’ve tested three Huawei phones (Mate 40 Pro, P60 Pro, Nova 11) and two Huawei laptops (MateBook X Pro, MateBook D) against a variety of displays: Huawei Vision TV, Samsung QLED, LG OLED, and a generic office monitor. Here’s what actually works.

Wireless Casting: The Easiest Way

Huawei phones support two main wireless protocols: Miracast (standard Android) and Huawei Cast+ (proprietary, lower latency). Most smart TVs support one or both. Here’s how to find them.

On a Huawei Phone (EMUI / HarmonyOS)

  1. Swipe down twice to open the full Quick Settings panel.
  2. Tap the “Wireless projection” icon (it looks like a phone with waves). If you don’t see it, swipe left to find it or tap the pencil icon to edit shortcuts.
  3. The phone will scan for nearby devices. Select your TV or monitor from the list.
  4. If a PIN appears on the TV, enter it on your phone. Done.
Pro tip: Many Huawei TVs have a built-in “Cast+” option that gives you much lower lag. If you see both “TV name” and “TV name (Cast+)”, always pick the Cast+ one for video or games.

For iPhone / iPad to Huawei TV

Huawei Vision TVs support Apple AirPlay 2 natively. Just open Control Center, tap Screen Mirroring, and choose your Huawei TV. No extra app needed.

Windows PC to Huawei Screen

Windows has built-in Miracast. Press Win + K, then select your Huawei display. Make sure both devices are on the same Wi-Fi network.

Multi-screen Collaboration: Huawei’s Superpower

This is Huawei’s own feature that lets you use your phone’s apps and files directly on a MateBook laptop—wirelessly. It’s available on most Huawei phones (EMUI 9.1+) and MateBooks (PC Manager 9.1+).

How to Set It Up

  1. On your phone, enable NFC and Bluetooth.
  2. On your MateBook, open PC Manager and click the “Phone” icon.
  3. Tap your phone’s NFC area (usually near the camera) against the MateBook’s “Huawei Share” tag (often on the palm rest).
  4. Accept the connection on both devices. Within seconds, your phone’s screen appears on the laptop.
What I love: You can drag files directly between the two screens. Want to edit a photo from your phone in Photoshop on the laptop? Just drag it over. No cables, no emailing yourself.

If NFC doesn’t work (common with third-party cases), you can also scan the QR code displayed in PC Manager with your phone’s Huawei Share app.

Wired Connections: When Wireless Just Isn’t Enough

Wireless is convenient, but sometimes you need rock-solid stability—like for a presentation or gaming. Huawei phones with USB-C (most models after 2019) support DisplayPort Alt Mode. That means you can output video straight through the USB-C port.

USB-C to HDMI Cable

Buy a USB-C to HDMI adapter (or cable). Plug it into your phone, then into the TV. The phone should automatically detect the external display. I’ve tested it with a $15 Anker adapter – works with Mate 40 Pro. Note: some older Huawei phones (like P20 Pro) don’t support video output; you’d need a DisplayLink adapter instead.

Huawei Easy Projection (Desktop Mode)

When you connect via USB-C, some Huawei phones (Mate series) can activate Desktop Mode – a PC-like interface on the big screen. You can use a Bluetooth mouse and keyboard. To enable it:

  • After connecting, pull down the notification shade.
  • Tap “Desktop Mode” (if available). Not all models have it.
  • Once in Desktop Mode, you can run multiple app windows side by side.
Heads-up: Desktop Mode is great for productivity, but many apps are just stretched phone versions. Don’t expect full desktop-grade software.

HDMI Cable from Laptop

Simple: plug and play. Most Huawei laptops have full-size HDMI ports. If yours doesn’t (e.g., MateBook X Pro), use a USB-C to HDMI adapter.

Common Connection Problems (and Fixes I’ve Tried)

Over the years, I’ve encountered (and solved) plenty of hitches. Here are the top three:

1. Phone Can’t Find the TV

  • Both devices must be on the same Wi-Fi network (for wireless casting).
  • Restart both the phone and the TV. I swear, half the issues vanish after a reboot.
  • For Huawei Cast+, ensure the TV supports it. Some older models don’t – then fall back to Miracast.

2. Lag or Stuttering

  • Wireless mirroring always has some delay. For gaming or fast-paced video, use wired USB-C.
  • If you must use wireless, enable “Game mode” on your TV – it reduces input lag.
  • Close bandwidth-hungry apps on your phone (like Netflix streaming)

3. No Sound from TV

  • Check the TV’s audio settings – sometimes it defaults to internal speaker while receiving video.
  • On Huawei phones, while casting, go to Sound Settings and ensure the output device is the TV.
  • Some adapters (especially cheap ones) don’t pass audio. Try a different adapter.

FAQ – Quick Answers from Real Experience

Can I connect a Huawei phone to a non-smart monitor?
Only if the monitor has HDMI with audio return. Most office monitors don’t have speakers – you’ll get video but no sound. For those, use a USB-C to HDMI adapter that includes a 3.5mm audio jack, or connect external speakers separately.
My Huawei P40 doesn’t have a “Wireless projection” toggle – what now?
It’s a known annoyance. Huawei moved it under Settings > More connections > Phone clone > Wireless projection in some older EMUI versions. Or just ask the phone: say “Hey Celia, turn on wireless projection.” Works every time.
Does screen mirroring work with Huawei FreeBuds while connected?
Yes, but there’s a catch. Audio routes through the phone, not directly to the TV. So if you’re mirroring a video, the sound goes to your FreeBuds, not the TV speakers. To hear from TV, disconnect Bluetooth audio.
Why does my Huawei laptop connect but the screen stays black?
Likely a refresh rate mismatch. Go to display settings on your laptop and set an external resolution that the monitor supports. Also, some USB-C docks don’t work – try direct HDMI.
