It is important to understand that the setup process depends on the model of your TV, version Android TV and type Chromecastdevice. For example, NVIDIA Shield TV or Xiaomi Mi Box may require additional steps, while on Sony Bravia with preinstalled Google TV everything works out of the box. We took these nuances into account and prepared universal solutions.

If you have never used technology before Google Cast, don’t worry: the instructions are suitable even for beginners. And experienced users will find here hidden settings to optimize data transfer speed and reduce lags.

1. Which Chromecast devices are compatible with Android TV?

Before you start connecting, make sure that your equipment supports the technology Google Cast. There are three main types of devices:

  • 📺 Chromecast built-in) —already preinstalled on TVs with Android TV 8.0+ or Google TV (for example, Sony X90J, TCL 6-Series, Philips The One).
  • 🔌 External Chromecast adapters —connected via HDMI port. This models Chromecast 3/4 generation, Chromecast with Google TV (with remote control) or Chromecast Ultra (for 4K).
  • 🎮 Android TV boxes with Cast support —for example, NVIDIA Shield TV, Xiaomi Mi Box S, Mecool KM2. Here the function can be called Miracast or Wireless Display.

To check the presence of built-in Chromecast on your TV:

  1. Open Settings → Devices and networks → Google Cast.
  2. Or use the search in the menu for "screen sharing».
⚠️ Attention: Some manufacturers (for example, LG or Samsung on models before 2020) use their own streaming protocols (Miracast, Smart ViewThey are not compatible with Google Cast!
Device type Chromecast support Is an external one required? adapter? Max. resolution
Android TV 8.0–10.0 Partial (depending on the model) Yes, if there is no built-in Cast 1080p or 4K
Google TV (Android 11+) Full (built-in Cast) No 4K HDR
Chromecast 3 Full Yes (HDMI) 1080p
Chromecast with Google TV Full + remote control Yes (HDMI) 4K Dolby Vision
NVIDIA Shield TV Full (via Google Cast) No 4K AI-upscaling

If your TV does not support Chromecast built-in, you will have to use an external adapter. Please note the version HDMI: for 4K@60Hz you need a port HDMI 2.0 or newer.

2. Preparing the TV and network: 5 mandatory steps

Before connecting Chromecast you need to configure the network and the TV device itself. Skipping these steps often leads to errors like “Device not found" or "Could not connect».

Enable Wi-Fi on your TV and smartphone|Connect your TV and phone to the same network|Update Android TV firmware|Disable VPN/proxy on all devices|Check for a free HDMI port (for external Chromecast)-->

Let's look at each point in more detail:

  1. Shared network Wi-Fi: Make sure that the TV and the device from which you will broadcast (smartphone, laptop), connected to one network. If you have a dual-band router (2.4 and 5 GHz), select one band for all devices. Chromecast does not support switching between frequencies!
  2. Firmware update: Outdated software is a common cause of failures. Update Android TV via Settings → About TV → System updateFor external ones. data-i="118">-devices use the application Chromecast-devices use the application Google Home.
  3. Router settings: Disable AP Isolation (client isolation) in the router control panel. This function blocks communication between devices on the local network. It is also recommended to secure IP address for the TV in DHCP-settings.
⚠️ Attention: If you use guest Wi-Fi network, Chromecast will not work. This network is isolated from the main one, and the devices will not see each other.

For owners Chromecast with Google TV (model with remote control) additionally check:

  • 🔋 Is the adapter connected to USB port TV (if there is no separate power supply).
  • 📶 Is the device located in an area of reliable Wi-Fi reception (no further than 10 meters from the router).
💡

If your TV does not see Chromecast, try rebooting the router. Sometimes IP address conflicts are resolved this way.

If you have an external adapter (for example, Chromecast 4 or Chromecast Ultra), follow these instructions. The process takes no more than 5–7 minutes.

Step 1: Physical connection

  1. Insert Chromecast into a free HDMI port TV. For models with HDMI-CEC (for example, Samsung Anynet+ or LG Simplink), select the port marked ARC or CEC.
  2. Connect cable USB to the power adapter (included) and plug it into a power outlet. Do not use the TV’s USB port —this may cause unstable operation.
  3. Turn on the TV and select the signal source corresponding to the port where it is connected Chromecast (for example, HDMI 1).

Step 2: Setup via Google Home

Download the application Google Home to your smartphone (Android or iOS) and do:

  1. Open the application and click "Add» → «Set up device» → «New device».
  2. Select your home (or create a new one), then wait for the application to find Chromecast.
  3. Confirm the code that appears on the TV screen.
  4. Connect the device to your Wi-Fi network (make sure it is the same network as the TV!).
  5. Set device name (for example, "Living room Chromecast") and select a room.

After setup Chromecast will be available for casting from supported applications (YouTube, Netflix, Spotify, etc.).

1. Make sure that the smartphone and Chromecast are connected to the same Wi-Fi network (not via mobile data!).

2. Restart the router and TV.

3. In the smartphone settings, turn off the power saving mode for the Google Home application.

4. Try using another smartphone or tablet.

5. If nothing helps, reset the Chromecast to factory settings by holding the button on the device for 25 seconds.

  • 🔄 Reboot Chromecast (turn off the power for 30 seconds).
  • 📱 Update the application from which you are trying to broadcast.
  • 🌐 Check if the firewall or antivirus on the router is blocking multicast traffic (needed to detect devices).
💡

For stable operation of Chromecast, it is recommended to use a router that supports the Wi-Fi 5 standard (802.11ac) or later. Older 802.11n routers may cause lag when broadcasting 4K.
