Connecting a laptop to TV with Android TV opens up new possibilities: from watching movies on the big screen to working with presentations or streaming games. However, not all users know that modern Smart TV based on Android support several connection methods - from classic HDMI before wireless technologies like Miracast or Google Cast. The main problem is choosing the optimal method that will ensure stable transmission of image and sound without delays.

In this article we will look at all current ways to connect a laptop to Android TV, including nuances for different operating systems (Windows 10/11, macOS, Linux) and TV models (Sony Bravia, Xiaomi Mi TV, Philips with Android TV). We will pay special attention to solving typical problems - lack of sound, low resolution or lags during broadcasting. If you want to turn your TV into a full-fledged monitor or media center, read on.

1. Connection via HDMI: classic and reliable way

The most universal method is to use HDMI cable. It is suitable for any laptop (even older models with VGA via adapter) and guarantees minimal signal delays. Modern TVs with Android TV (For example, Sony X80J or TCL 6-Series) are usually equipped with several HDMI-ports, one of which is often marked as ARC/eARC — it is better to use it to transmit sound back to the laptop (if required).

To connect:

  • 🔌 Connect one end HDMI cable to the laptop, the other to the TV. On some ultrabooks (for example, MacBook Air or Dell XPS 13) may be required USB-C to HDMI adapter.
  • 📺 On the TV remote control, press the button Source (or Input) and select the appropriate HDMI port.
  • 💻 On a laptop, press the key combination to duplicate the screen:
    • Windows: Win + P → select mode Duplicate or Expand.
    • macOS: Option + F1 (or System Preferences → Displays).

Turn off both devices before connecting the cable|Check HDMI version (2.0 for 4K 60Hz)|Update graphics card drivers on your laptop|Adjust screen resolution in system settings-->

If the image does not appear:

⚠️ Attention: On some TVs Android TV (For example, Philips 7500 Series) by default the mode is enabled HDMI-CEC, which may block the signal. Disable it in settings: Settings → Devices → HDMI-CEC.
Problem Reason Solution
No image Incorrect signal source selected Click Source on the remote control and select the one you want HDMI
Low resolution (720p) Automatic Windows setup Manually install 1920×1080 or 3840×2160 in screen options
No sound Sound is output to laptop speakers In the Sound Control Panel, select your output device TV (HDMI)

2. Wireless connection via Wi-Fi (Miracast and Google Cast)

If wires annoy you, you can use wireless technologies. TVs with Android TV support two main standards:

  • Miracast — live screen broadcast without internet (works on Windows 10/11 And Android).
  • Google Cast — content transfer via Google Chrome or applications (for example, YouTube, Netflix).

For Miracast:

  1. On TV: go to Settings → Devices → Wireless Projection (on Xiaomi Mi TV it could be Settings → Connection and sharing → Miracast).
  2. On a laptop with Windows: 
    Win + K → выберите ваш телевизор из списка

    If the option is missing, check support Miracast through the command in PowerShell:

    Get-WmiObject -Namespace root\wmi -Class MSWiFi_DirectAdvertisement
📊 Which connection method do you use most often?
  • Via HDMI
  • Via Wi-Fi (Miracast)
  • Via Google Cast
  • Other

For Google Cast:

  • 🌐 Make sure your laptop and TV are connected to the same Wi-Fi networks.
  • 🖥️ In the browser Google Chrome click ⋮ → Broadcast and select your TV.
  • 📱 Or use apps that support Chromecast (For example, VLC for video broadcasting).
⚠️ Attention: When broadcast via Miracast on TVs Sony Android TV There may be an audio delay of up to 200 ms. For games or videos this is critical - use HDMI.
💡

If your TV doesn't appear in the list of devices for Miracast, try disabling your VPN or firewall on your laptop - they may be blocking detection.

3. USB-C connection: for modern laptops

Laptops with port USB-C (For example, MacBook Pro, Lenovo Yoga or HP Spectre) can be connected to the TV via an adapter USB-C → HDMI or directly if the TV supports USB-C DisplayPort Alt Mode (For example, LG OLED C2 with Android TV). The main advantage is the transmission of not only video, but also power (up to 100W), allowing you to charge your laptop while in use.

Instructions:

  1. Purchase a certified adapter (we recommend Anker or Belkin for 4K@60Hz).
  2. Connect the adapter to USB-C laptop port, and HDMI- cable - to the TV.
  3. On a laptop with macOS You may need to confirm your device's trust in System settings → Screens.
Adapter Max. resolution Audio support Price (approx.)
USB-C → HDMI (passive) 1080p@60Hz Yes 500–1000 ₽
USB-C → HDMI (active, with chip) 4K@60Hz Yes 2000–4000 ₽
USB-C → DisplayPort 4K@120Hz No (video only) 3000–5000 ₽
Why might USB-C not work?

If the laptop does not support DisplayPort Alt Mode (for example, budget models Acer or Asus), the adapter will not be able to transmit video. Check the specifications of your model on the manufacturer's website.

4. Using DLNA to transfer media files

If you do not need to duplicate the screen, but only broadcast movies, music or photos, the protocol will suit DLNA. It allows you to stream content from your laptop to your TV via a local network. Most TVs with Android TV (For example, Hisense A6 or Sharp Aquos) have a built-in DLNA server.

How to set up:

  • 📁 Install a media server program on your laptop:
    • Windows: Plex, Kodi or built-in Streaming media (DLNA) in Settings → Networks.
    • macOS/Linux: MiniDLNA or Rygel.
  • 📺 On your TV, open the application Media player or Photo and video (on Sony it could be Media Player).
  • 🔍 Select your laptop from the list of available devices.

Benefits DLNA:

  • ✅ No delays (unlike Miracast).
  • ✅ Subtitles and playlists are supported.
  • ✅ Works even on weak laptops.
⚠️ Attention: Some TVs (eg. Xiaomi Mi TV Stick) do not support DLNA for video format MKV with codec HEVC. In this case use Plex with transcoding.

5. Connection via Ethernet (for stable streaming)

If Wi-Fi works unstable, can be used wired connection through Ethernet. This is relevant for broadcasting 4K HDR-content or online games (for example, through GeForce NOW or Xbox Cloud Gaming). Most TVs with Android TV have LAN port, and the laptop can be connected via USB-Ethernet adapter (For example, TP-Link UE300).

Connection diagram:

  1. Connect your laptop and TV to your router via Ethernet cables.
  2. Turn off on TV Wi-Fi in Settings → Network and activate the wired connection.
  3. For streaming use Google Cast or Steam Link (for games).
💡

A wired connection reduces latency to 10–20 ms, which is critical for cloud gaming or 4K video.

6. Solving common problems

Even after a successful connection, difficulties may arise. Here are the most common ones and how to fix them:

Problem Possible reason Solution
The TV does not see the laptop via Wi-Fi Different networks (2.4 GHz vs 5 GHz) Connect both devices to the same network (preferably 5 GHz)
The sound comes only through the laptop Wrong output device B Control Panel → Sound select TV (HDMI)
The image is cropped at the edges Incorrect aspect ratio On the TV, turn on the mode Just Scan or Screen Fit
Lags when broadcasting via Miracast Weak Wi-Fi signal Use HDMI or connect to the router via cable

If the TV does not recognize the laptop via HDMI:

  • 🔄 Reboot both devices.
  • 🔧 Update the video card drivers on your laptop (especially important for NVIDIA/AMD).
  • 📺 Reset your TV settings HDMI-port: Settings → External devices → Reset HDMI.

7. Optimize picture and sound

After connecting, it is important to configure resolution And update rate for comfortable viewing. On TVs with Android TV this is done manually:

  • 🎮 For games: install 1080p@120Hz or 4K@60Hz (if supported).
  • 🎬 For movies: select 4K@24Hz (for cinematic effect).
  • 🔊 For sound: in the TV settings, activate Dolby Atmos or DTS:X, if your laptop supports these formats.

On Windows:

  1. Open Screen Options (Win + I → System → Display).
  2. Select your TV and press Additional display options.
  3. Set the recommended resolution (usually 3840×2160 for 4K).

On macOS:

  1. Go to System Settings → Monitors.
  2. While holding Option, press Scaleto see all available resolutions.
💡

If colors on your TV look washed out, check your settings Color space in the video card drivers. For HDR content, select BT.2020 instead of sRGB.
