The fastest way to cast from your tablet to your TV
Most tablets can send video and audio to a TV wirelessly using one of three methods: built-in casting (AirPlay on iPad, Chromecast on Android), a streaming device you plug into the TV's HDMI port, or a cable connection. Which one works depends on what tablet you own, what TV you have, and whether you already own a streaming device.
If your tablet is an iPad, AirPlay is built in — you swipe down from the top right, tap Screen Mirroring, and select your Apple TV or AirPlay-compatible smart TV. If your tablet runs Android, you use Google Cast (called Cast on most Android tablets), which works the same way but requires either a Chromecast device plugged into your TV or a TV with built-in Chromecast. If you have neither, a wired HDMI adapter is the fallback that works with almost any TV.
Key Takeaways
- iPad uses AirPlay, which works with Apple TV or any smart TV that supports AirPlay — no extra device needed if your TV is recent enough.
- Android tablets use Google Cast, which requires either a Chromecast device (about $30 to $50) or a TV with Chromecast built in.
- A wired HDMI adapter (USB-C or Lightning to HDMI, $15 to $40) works with any TV and any tablet but requires a cable and keeps the tablet tethered.
- Wireless casting works best on the same WiFi network as your TV or streaming device, and both must be powered on.
- Some tablets and TVs support Miracast, an older wireless standard that works across brands but is less common on newer devices.
AirPlay casting for iPad to any compatible TV
If you own an iPad, AirPlay is the simplest option because it is built into every iPad made in the last ten years. You do not need to buy anything extra. Open any app on your iPad — video, photos, music, or screen mirroring — and swipe down from the top right corner to open Control Center. Tap Screen Mirroring, and a list of available devices appears. Select your TV or Apple TV, and your iPad's screen appears on the TV within seconds.
AirPlay works with Apple TV (any generation), and also with many newer smart TVs from Samsung, LG, Sony, and other brands that have added AirPlay support in the last few years. Check your TV's manual or settings to confirm it supports AirPlay. If your TV is older or does not have AirPlay, an Apple TV device (starting around $100) plugged into your TV's HDMI port will add it. Once connected, your iPad and Apple TV must be on the same WiFi network.
To stop casting, swipe down to Control Center again, tap Screen Mirroring, and select Disconnect. The iPad screen returns to normal, and the TV display stops.
Google Cast for Android tablets to Chromecast or compatible TVs
Android tablets use Google Cast (often just called Cast) to send video and audio to a TV. The process is similar to AirPlay: open an app that supports casting — YouTube, Netflix, Google Photos, Chrome browser, or many others — and look for a Cast icon (usually a rectangle with a WiFi symbol in the corner). Tap it, select your Chromecast device or compatible TV, and the content appears on your screen.
To use Cast, you need either a Chromecast device plugged into your TV's HDMI port (Chromecast costs $30 to $50 depending on the model) or a TV with Chromecast built in. Many newer smart TVs from Samsung, LG, Sony, and TCL include Chromecast, so check your TV's settings or manual first. If your TV does not have it, a Chromecast device is the cheapest way to add casting. Both your tablet and the Chromecast device must be on the same WiFi network.
Not every app supports Cast — some streaming services limit it for licensing reasons. If you do not see a Cast icon in an app, that app does not support it. You can also cast your entire Android tablet screen using the system-level Cast option in your tablet's settings, though this drains battery faster than casting from an app.
Wired HDMI connection for any tablet and TV
If you do not have a compatible TV or streaming device, a wired HDMI adapter is the most reliable fallback. You connect an adapter to your tablet's charging port (USB-C on most Android tablets, Lightning on iPad) and run an HDMI cable from the adapter to your TV's HDMI port. The tablet's screen appears on the TV when ready, and you can control everything from the tablet as normal.
HDMI adapters cost $15 to $40 depending on the brand and tablet type. They work with any TV that has an HDMI port, which is nearly every TV made in the last fifteen years. The downside is that your tablet stays physically connected to the TV by cable, which limits where you can sit and drains the tablet's battery faster because it is powering the video output. Some adapters include a charging port so you can plug in power while casting, which solves the battery problem.
To use an HDMI adapter, plug it into your tablet, connect the HDMI cable, and switch your TV to the correct HDMI input using the remote. The tablet screen should appear within a few seconds. No pairing or WiFi setup is needed.
Miracast wireless casting on older Android tablets and Windows tablets
Miracast is an older wireless casting standard that works across different brands without needing a Chromecast device or Apple TV. Some Android tablets and most Windows tablets support it. To use Miracast, open your tablet's settings, look for Screen Mirroring or Wireless Display, and select your TV from the list. Your TV must also support Miracast, which is less common on newer models than Chromecast or AirPlay.
Miracast is useful if you have an older tablet and an older TV that both support it, because you do not need to buy a streaming device. However, Miracast has largely been replaced by Chromecast and AirPlay on newer devices, so it is becoming less common. Check your tablet's manual to see if Miracast is listed as a feature. If it is not mentioned, your tablet probably does not support it.
Troubleshooting casting problems
If casting does not work, the most common cause is that your tablet and TV (or streaming device) are not on the same WiFi network. Check that both are connected to the same network name. Restart both devices — turn off the tablet and TV completely, wait ten seconds, and turn them back on. This fixes most connection problems.
If you are using a Chromecast or Apple TV, make sure it is powered on and has been set up in the same room as your tablet. If the device is in a different room or on a different network, casting will not work. For wired HDMI, check that the cable is fully inserted into both the adapter and the TV, and that your TV is set to the correct HDMI input number.
If an app does not show a Cast icon, that app may not support casting. Try a different app like YouTube or Netflix to test whether casting itself is working. If those work, the problem is with that specific app, not your tablet or TV.

Frequently Asked Questions
Do I need WiFi to cast from my tablet to my TV?
Wireless casting methods (AirPlay, Google Cast, Miracast) require both devices to be on the same WiFi network. A wired HDMI adapter does not need WiFi at all — it works as long as the cable is connected. If your WiFi is unreliable, a wired adapter is more dependable.
Can I cast to a TV that does not have a smart TV or streaming device?
Yes, using a wired HDMI adapter. Any TV with an HDMI port can receive video from a tablet through an adapter. If your TV is very old and has no HDMI port, you would need an older adapter that uses composite or VGA connections, which are harder to find and less reliable.
What happens to my tablet screen while I am casting?
When you cast an app (like Netflix or YouTube), your tablet screen shows the app normally, and the TV shows the same content. You control playback from the tablet. When you cast your entire tablet screen using screen mirroring, whatever appears on the tablet also appears on the TV, including notifications and any app you open.
Can I use my tablet while casting?
Yes. When casting an app like YouTube, you can use other apps on your tablet at the same time — the video keeps playing on the TV. When casting your entire screen, anything you do on the tablet shows on the TV, so opening another app will change what the TV displays.
Why does my tablet get hot when casting?
Casting uses more power than normal tablet use, which generates heat. This is normal. If your tablet becomes too hot to touch, stop casting and let it cool down. Using a wired HDMI adapter with a charging cable plugged in reduces heat because the tablet is not draining its battery.
