Want to watch a video on your phone but hate squinting at a 6-inch screen? If you’ve got a Samsung TV, you can usually throw that content onto the big screen in a couple of taps, whether it’s a YouTube clip, a photo slideshow, or a browser tab.
Thanks to built-in casting and screen-mirroring tools (plus options like Google Chromecast and Apple AirPlay), turning your TV into a giant version of your phone is easier than most people think. The key is knowing which method your devices support, and making sure they’re on the same Wi‑Fi network.
What “casting” actually means
Sommaire
In everyday tech speak, “casting” means sending content from one device to another, most often from a phone, tablet, or laptop to a TV. Think: streaming a video, sharing music, showing a document, or putting a Chrome browser tab on your television.
The term took off with Google’s Chromecast, a small streaming device Google introduced years ago that made it simple to beam compatible apps to a TV. Today, many Samsung TVs support casting features directly, without extra hardware, depending on the model and year.
The simplest option: mirror your Samsung phone to a Samsung TV
If you own both a Samsung smartphone and a Samsung TV, you’re in the easiest lane. Samsung devices are designed to work together, and screen mirroring is often the fastest way to get your phone’s display onto your TV.
Mirroring is exactly what it sounds like: your TV shows a live copy of what’s on your phone. It’s wireless, it’s quick, and it’s ideal for anything that doesn’t have a dedicated “Cast” button, like photos, settings screens, or certain apps.
For mirroring to work smoothly, both devices need to support the feature. Your phone has to be able to send the screen signal, and your TV has to be able to receive and display it. When both are Samsung, compatibility is usually better and setup is less painful.
How to cast from an app to your Samsung TV
Start with the basics: connect both your phone (or tablet) and your Samsung TV to the same Wi‑Fi network. If they’re on different networks, or one is on cellular data, casting often won’t work.
Next, open the app that has what you want to watch or play. Look for the Cast icon (it often resembles a small screen with Wi‑Fi waves in the corner). Tap it, then select your Samsung TV from the list of available devices.
When the Cast icon changes color or looks “filled in,” that’s your sign you’re connected. Hit play, and your content should appear on the TV.
If it doesn’t work, don’t overthink it, most failures come down to a missed step. Double-check Wi‑Fi, try again, and make sure the TV is powered on and discoverable. When you’re done, tap the Cast icon again and choose “Disconnect” on your phone.
Samsung’s built-in tools: Smart View and SmartThings
Samsung also offers its own casting and control apps, including Smart View and SmartThings. Both can help you connect and share content over Wi‑Fi, especially if you’re staying inside the Samsung ecosystem.
In general, Smart View tends to work with older Samsung TV models (including many sets from the early-to-mid 2010s), while SmartThings is geared toward newer Samsung TVs, especially models released after 2016. If one app doesn’t see your TV, the other one might.
Using Google Chromecast with a Samsung TV
If your Samsung TV doesn’t have casting built in, or you want a reliable, app-friendly option, Google Chromecast is one of the most common solutions. Chromecast works with a wide range of streaming apps and is designed specifically for casting.
Setup is straightforward: plug the Chromecast device into an HDMI port on your TV, then connect it to your Wi‑Fi network. Once it’s online, compatible apps on your phone will be able to send video or audio directly to the TV through Chromecast.
Some Samsung TVs also come with Chromecast-style casting features already included. Before buying anything, check your TV’s settings or model specs to see what it supports, you may not need extra hardware at all.
Apple’s option: AirPlay on Samsung TVs
If you’re using an iPhone, iPad, or Mac, Apple’s casting system is called AirPlay. It runs over Wi‑Fi and can send video, audio, or even your entire screen to a compatible TV.
Many newer Samsung TVs support AirPlay, which means you can cast directly from Apple devices without an Apple TV box. If you’re going the wired route from a Mac, you’ll typically need a compatible video output (like HDMI, Thunderbolt, or an adapter) and the right cable to carry both picture and sound to the TV.
