If you think hooking up your phone to your TV is a complicated business, think again. While it used to be difficult or impossible in the past, a range of technologies, cables, and inexpensive gadgets now makes it a much simpler proposition.

Whether you’re wanting to watch your favorite shows, listen to music, play games, cycle through your vacation snaps, or simply show whatever is on your phone on a larger screen, it’s usually possible and relatively straightforward to do.

The techniques below will often also work for streaming to a TV from an iPad or other tablet and from many laptops. They’re particularly useful for anyone traveling and looking to make better use of the television in their hotel or Airbnb, but the same approaches work just as well when you’re at home.

Plug in an HDMI Cable

HDMI cable

The most obvious approach is to simply connect an HDMI cable between the phone, tablet, or laptop and the TV. Of course, while virtually all modern televisions will have a spare HDMI port, the same can’t be said for mobile devices. A few tablets and laptops have mini- or micro-HDMI sockets, but less so in recent times. Current smartphones definitely don’t.

There are plenty of cables to help get around that issue, but as usual, the devil is in the details. A high-quality USB C to HDMI cable will do the job for modern devices with a USB C port, but they need to support both USB C 3.0 and DisplayPort Alternate Mode.

None of my phones or tablets, even brand new ones, have that support built in. You may have better luck with other devices, especially Samsung ones, so just be sure to double-check the exact specifications and reviews of your device before you buy. Recent laptops are much more likely to support this: the above cable works perfectly with both a Macbook Pro and a Lenovo Yoga 920.

If you’ve got an older Android device with a micro-USB port, you may be able to use either a Slimport or active MHL adapter to do the same thing. Again, it’s important to make sure your phone or tablet supports one or the other standard before purchase.

For iPhones and iPads, your best bet is the official Apple Lightning to Digital AV adapter, along with a standard HDMI cable. It’s more expensive than buying one of the many near-identical third-party cables, but also works a lot more reliably.

Once you’ve got the physical connection sorted out, the rest is easy. It’s a simple mirrored display: whatever you see on the phone screen shows on the television. There may be some differences in aspect ratio, with a possibility of black bars at the top and bottom or sides of the larger screen, but that’s about it.

The biggest benefit of using a physical cable is the reliability of the connection. You’ll get the least amount of delay, stuttering, or dropouts with this approach, and it’ll work with the widest range of TVs. If you’re planning to game on the big screen, this is by far the best approach.

Stream Wirelessly Using Miracast

Casting from Android to TV

Miracast is one of those tech features that feels a bit like magic when you first discover it. Built into most recent versions of Android, Windows, and Linux, it lets you stream video and audio to the majority of smart TVs without needing a cable. It has been described as “HDMI over Wi-Fi,” which gives a pretty good idea of how it works.

Like an HDMI cable, Miracast mirrors your device’s display on the television screen. The exact method for setting it up depends on both the TV and your device’s operating system, but I’ve outlined the general approach. below

To get it working, you’ll first need to switch your TV’s input so it starts listening for an incoming connection. The input will likely be called Cast, Miracast, or something similar. My TV calls it “Anyview Cast,” for example.

To make the connection on Android, select Screen Cast from the Quick Settings menu, or go to Settings–Bluetooth & device connection–Cast. Ensure that “Enable Wireless Display” is checked in the hamburger (three dots) menu, and you should see the television listed either by name or a generic phrase like “Smart TV.” Select it and wait a few seconds, and all going well, a copy of your phone’s display will appear on the screen.

Windows has a similar approach. On Windows 10, click the Action Center icon on the right of the taskbar, then click Connect. Choose the television from the list of audio/video devices that appears, and wait a few seconds for the connection to be made.

Note that Apple doesn’t support Miracast, so if you want wireless streaming, you’ll need to connect another device: either an Apple TV or a Chromecast, Roku, etc as below.

If you’re traveling, a useful bonus of Miracast versus other wireless options is that it doesn’t require you (or the TV) to have access to an existing Wi-Fi network. Even if the hotel’s network is restricted, unavailable, or impossibly slow, you can still happily stream as long as you have a cellular data connection or content stored locally on your device.

Note that any wireless display, including both Miracast and the streaming devices mentioned below, is inherently slower and less reliable than a physical cable. In many cases you’ll barely notice the difference, but it’s not ideal for gaming.

Use a Dedicated Streaming Stick

If neither of the above options works for you, it’s time to turn to a third-party solution. Fortunately these are neither complicated nor expensive: for around $30, you can grab a small gadget that plugs into an HDMI port on your TV and lets you stream content direct over Wi-Fi.

We’ve covered some of the best streaming sticks in some detail in the past. Any of them will let you use your phone and a Wi-Fi connection to play audio or video content on a television, although they don’t all do it in exactly the same way.

The Roku and Amazon Fire TV sticks mainly rely on their extensive collection of streaming apps, which you select in the companion iOS or Android app. Chromecasts use the Google Home app to manage overall setup and playback, and a Cast icon appears in supported apps once you’re connected to the device. From there, a single tap offloads the audio and/or video to the TV.

Chromecast screen in Google Home app

In either case, major streaming services like Netflix, Hulu, YouTube, and many others are supported on both devices. Chromecast also lets you stream web pages via the Chrome browser. If you’re using an Android phone or tablet and want to stream locally-stored content from your phone to the Roku or Chromecast, an app like AllCast will let you do so.

If you want to simply mirror whatever is on your phone or tablet and your TV doesn’t have Miracast support (above), Roku and Chromecast natively support screen mirroring on both Android and iOS as well. The Amazon sticks officially support it for Android, and third-party solutions are available for iOS.

For iPhone and iPad owners, any of these sticks are good alternatives to Apple TV if you’re looking for a cheaper, smaller streaming solution. They’ve also got the advantage of being cross-platform, which is very useful if you’re not an all-Apple household.
