The trickiest part isn't whether you can connect—it's knowing which standard works.
In an age when the screen in our pocket has become our primary window to media, the question of how to share that window with a larger room has grown quietly urgent. CNET maps the landscape of wireless casting — AirPlay, Chromecast, and Miracast — as a practical guide to the small but meaningful friction of connecting our personal devices to the televisions we encounter at home and away. The answer, it turns out, depends less on technology's limits than on knowing which language your particular devices share.
- The frustration is familiar: a phone full of content, a television within reach, and no obvious path between them — especially in unfamiliar spaces like hotel rooms or vacation rentals.
- The casting ecosystem has quietly fragmented into at least three competing standards — AirPlay, Chromecast, and Miracast — each with different device allegiances and different capabilities, making compatibility the central obstacle.
- iPhone users gain flexibility through AirPlay's expanding reach across Samsung, LG, TCL, Vizio, and Roku devices, but must accept that Chromecast cannot mirror their full screen the way AirPlay can.
- Android users enjoy near-universal Chromecast support, while Samsung and Motorola owners hold an additional card in Miracast, which extends screen mirroring even to Windows PCs.
- The hidden variable undermining even well-matched devices is Wi-Fi signal strength — proximity to the router, not just protocol compatibility, often determines whether the stream holds or falters.
You're in an unfamiliar living room, phone in hand, and the last thing you want is to dig through a rental TV's menus. Wireless casting exists precisely for this moment — but which method works depends entirely on what devices you're holding.
For iPhone users, AirPlay is the native path. Once confined to Apple TV boxes, it now runs on televisions from Samsung, LG, TCL, and Vizio, as well as Roku devices. You can trigger it from within streaming apps or from the Control Center, where full-screen mirroring lets you cast apps like Instagram that lack built-in casting support. Chromecast is a second option for iPhones, recognizable by its rectangle-with-wavy-lines icon, though it cannot mirror the full iPhone display the way AirPlay can.
Android phones universally support Chromecast, either through smart TVs with it built in or via a separate Chromecast device. The Google Home app enables full-screen mirroring, and a quick-settings shortcut can make casting faster. Samsung and Motorola users also have access to Miracast — called Smart View and Ready For, respectively — which works with screen-mirroring televisions and even Windows PCs, useful for gaming or desktop-style tasks.
The real challenge isn't capability but compatibility: knowing which standards your phone and TV share. At home this is manageable; while traveling, mismatches are common. A strong Wi-Fi signal matters as much as the right protocol — staying close to the router and resetting the cast connection when quality drops are simple habits that make the difference between a seamless experience and a frustrating one.
You're in an unfamiliar living room, streaming app already open on your phone, and the last thing you want to do is hunt through a rental TV's menus to log in. This is the problem that wireless casting solves—and it turns out there are now several ways to make it work, depending on what phone and television you happen to have in front of you.
The basic principle is simple: your phone can send video to your TV without a cable. But the method matters. iPhones have access to two main pathways. AirPlay, Apple's native system, originally worked only with Apple TV boxes, but it has since expanded to televisions from Samsung, LG, TCL, and Vizio, as well as Roku streaming devices. If a TV supports the Apple TV app, it almost certainly supports AirPlay somewhere in its settings. You can trigger it from within apps like Paramount Plus by tapping the AirPlay icon—a TV with a triangle—or you can access it through your phone's Control Center using the two-rectangles icon, which also lets you mirror your entire screen to display apps that don't have built-in casting support, like Instagram or TikTok.
The second option for iPhone users is Chromecast, Google's casting standard. You'll recognize the icon as a rectangle with three wavy lines. The trade-off is that while Chromecast works fine for sending video from apps, you cannot mirror your iPhone's full display over Chromecast the way you can with AirPlay. Some apps, like YouTube, let you choose between both methods in a single menu for convenience. There's also a wired fallback: Apple sells a Lightning-to-HDMI adapter if you have access to a cable.
Android phones take a different route. Every Android device supports Chromecast, whether your TV has it built in or you're using a separate Chromecast device. You can cast from supported apps by tapping the Cast icon, or you can use the Google Home app to mirror your entire screen. Many Android phones also let you add a Screen Cast shortcut to your quick settings for faster access. Beyond Chromecast, Samsung and Motorola phones offer an additional option called Miracast—branded as Smart View on Samsung devices and Ready For on Motorola phones. This standard works with televisions that have screen mirroring enabled, and notably, it also works with Windows PCs, which can be useful if you're trying to play games or do other activities that benefit from a larger display.
Both Samsung and Motorola phones can also connect via USB-C to HDMI cable if you need a more stable connection for data-intensive tasks. The cable approach can be particularly helpful when you want to use your phone more like a desktop computer.
In practice, the biggest challenge isn't whether you can connect—odds are you can—but rather knowing which standard your specific phone and TV both support. At home, where you control the equipment, this is usually straightforward. When traveling, you might find yourself with an Android phone in a hotel room that only supports AirPlay, or facing a TV with its HDMI port blocked. The solution is to plan ahead and understand what your phone can do.
One often-overlooked factor is your network itself. A wireless casting connection is only as strong as your Wi-Fi signal, so keeping your phone close to the router helps. If video quality drops during streaming, try turning the casting off and back on to reset the connection. With those basics in mind, you should be able to send whatever's on your phone to nearly any modern television.

La Conversación del Hearth Otra perspectiva de la historia
Why does it matter that there are multiple standards? Why didn't one just win?
Because the standards came from different companies at different times. Apple built AirPlay first, Google built Chromecast, and Miracast emerged as an industry standard. Now that phones and TVs support multiple options, it's actually convenient—but it also means you have to know what you're holding.
So if I'm buying a TV today, what should I look for?
Look for a TV that supports at least two of these three: AirPlay, Chromecast, or Miracast. That way, whether you're visiting with an iPhone friend or an Android friend, someone can cast without hunting for an adapter.
What about the network thing you mentioned—how much does Wi-Fi strength actually matter?
It matters more than people think. A weak signal won't necessarily break the connection, but it will degrade the video quality. If you're streaming 4K video, you want to be close to the router. If you're just mirroring a photo app, you have more flexibility.
Is there ever a reason to use a cable instead of wireless?
Yes. If you're doing something that demands a lot of bandwidth—using your phone as a second monitor for work, or playing a graphics-heavy game—a wired connection is more stable. Wireless is convenient, but wired is reliable.
And if you're in a hotel with a TV that doesn't support your phone's casting method?
Then you're stuck. You either find an HDMI adapter, ask the hotel for a different room, or you watch on your phone. It's rare now, but it happens.
