The fastest way: HDMI cable or USB-C adapter

The simplest method is a direct cable connection. Most modern Apple laptops have a USB-C port that outputs video. You need a USB-C to HDMI adapter (about $15 to $25) and an HDMI cable. Plug the adapter into your laptop's USB-C port, connect the HDMI cable to the adapter and to your TV's HDMI input, then switch your TV to that HDMI channel. Your laptop screen appears on the TV within seconds.

If your TV is older and has no HDMI port, or if you want to avoid adapters, a USB-C to VGA adapter works the same way — plug it in, run a VGA cable to your TV, and switch inputs. VGA adapters cost about the same as HDMI ones.

Older MacBook Pro models (2015 and earlier) have Thunderbolt 3 ports that also output video through USB-C adapters. The process is identical: adapter, cable, TV input switch.

Key Takeaways

  • A USB-C to HDMI adapter and HDMI cable is the cheapest and fastest wired connection for any recent Apple laptop.
  • AirPlay wireless mirroring works if your TV has AirPlay built in or if you own an Apple TV box connected to your TV.
  • Wired connections are more reliable than wireless for video calls, gaming, or presentations because they do not depend on WiFi strength.
  • Your laptop will treat the TV as an external display — you can mirror the screen or extend it to show different content on each.

Wireless mirroring with AirPlay

If your TV supports AirPlay 2, you can mirror your laptop screen without any cables. Open Control Center on your Mac (click the icon in the top-right corner), select Airplay, and choose your TV from the list. Your screen appears on the TV within a few seconds. This works on any MacBook from 2018 onward.

Not all TVs have AirPlay built in. Samsung, LG, and some Sony models support it, but you will need to check your TV's manual or settings to confirm. If your TV does not have AirPlay, an Apple TV box (the small black device, not the service) connected to your TV's HDMI port acts as a receiver. Once the Apple TV is on the same WiFi network as your laptop, you can AirPlay to it the same way.

AirPlay is convenient for casual use — watching a video, showing photos, or presenting slides — but it can lag slightly if your WiFi is slow or crowded. For video calls or fast-paced gaming, a wired connection is more stable.

Extending versus mirroring your display

When you connect your laptop to a TV, macOS gives you two options. Mirroring shows the same image on both screens — useful for presentations or when you want everyone to see what you see. Extending treats the TV as a second display, so you can drag windows between your laptop and the TV and use them independently.

To choose between them, go to System Settings, click Displays, then select the TV in the sidebar. A checkbox labeled "Mirror displays" appears. Check it to mirror, uncheck it to extend. Extending is helpful if you want to keep notes on your laptop while showing a video on the TV, or if you need extra screen space for work.

Troubleshooting a blank screen

If you plug in the cable and the TV stays blank, first make sure you switched to the correct HDMI input. Use your TV remote to cycle through inputs until you see your laptop screen. If that does not work, restart your laptop — sometimes the video driver needs to reset.

On your Mac, go to System Settings, click Displays, and look for the TV listed under "External Displays." If it does not appear, unplug the adapter, wait 10 seconds, and plug it back in. If the TV still does not show up, try a different USB-C port on your laptop if you have one.

For AirPlay issues, make sure your laptop and TV (or Apple TV) are on the same WiFi network. Restart both devices if AirPlay does not appear in Control Center. Some older routers do not handle AirPlay well — if mirroring is choppy or keeps disconnecting, a wired HDMI connection is more reliable.

Audio output and volume control

When you connect to a TV via HDMI or AirPlay, sound automatically plays through the TV's speakers. You control volume from your Mac's volume keys or from the TV remote. If you want sound to come from your laptop speakers instead, go to System Settings, click Sound, and select your laptop under "Output Device."

If the TV has no sound, check that your Mac is not muted (look for the speaker icon in the menu bar) and that the TV volume is not at zero. Some TVs require you to manually select the HDMI input before sound will play — switching inputs again usually fixes it.

Using your TV as a permanent second monitor

If your TV is mounted on a wall near your desk, you can leave it connected and use it as a permanent extended display. Your laptop will remember the connection and automatically detect the TV when you power it on. Arrange your windows so work apps stay on your laptop and video or reference material appears on the TV.

Keep the HDMI cable plugged in and routed behind furniture or through cable covers to avoid tripping hazards. If you use the TV this way regularly, a powered USB-C hub (which includes HDMI and charges your laptop at the same time) is more convenient than swapping adapters.

Frequently Asked Questions

Do I need an Apple TV box to connect my laptop to my TV?

No. A USB-C to HDMI adapter and cable work with any TV that has an HDMI port. An Apple TV box is only needed if you want wireless AirPlay and your TV does not have AirPlay built in.

Can I charge my laptop while it is connected to the TV?

A straightforward HDMI adapter does not charge your laptop. If you want both video and charging, buy a USB-C hub with HDMI — it has an HDMI port and a charging port in one device, though it costs $30 to $60.

Why is my AirPlay connection dropping?

AirPlay relies on WiFi, which can be unreliable if your router is far from your laptop or TV, or if many devices are on the network. Move closer to the router, reduce interference from other devices, or switch to a wired HDMI connection for stability.

What if my TV is too old for HDMI?

Use a USB-C to VGA adapter instead of HDMI. VGA is an older video standard that older TVs often have. The process is the same: plug the adapter into your laptop, run a VGA cable to the TV, and switch inputs.

Can I use my TV as a display while playing a video game?

Yes, but a wired HDMI connection is better than AirPlay for gaming because it has less delay. Plug in the adapter, extend your display, and run the game on the TV window. Close other apps on your laptop to reduce lag.
