You’re staring at that tiny 6.1-inch screen, trying to show your friends a video of your cat doing something vaguely athletic, and honestly, it’s a struggle. Everyone is squinting. Someone bumps your elbow. It’s just not working. You want to know how to play an iPhone on a TV because, let’s face it, that 65-inch OLED in your living room is sitting there doing nothing while you strain your eyes.
Getting your iPhone content onto the big screen should be easy. Apple says it’s easy. But then you try it and the audio desyncs, or the "AirPlay" icon mysteriously vanishes into the digital ether. It’s frustrating. I’ve spent years troubleshooting home theater setups and the truth is that the "best" way to do this depends entirely on whether you care about lag, if you’re trying to game, or if you just want to scroll through TikTok without holding your phone.
The AirPlay 2 Reality Check
AirPlay is the most common way people try to connect. If you have a Roku, a Vizio, a Samsung made after 2018, or an Apple TV box, you already have the hardware. You swipe down to your Control Center, tap those two overlapping rectangles, and boom—your phone is on the TV.
Except when it isn't.
AirPlay relies heavily on your local Wi-Fi network’s congestion. If your roommate is downloading a 100GB Call of Duty update in the other room, your AirPlay stream is going to look like a slideshow from 1998. Most people don't realize that AirPlay 2 actually uses a buffer to keep things smooth, which is great for movies but terrible for anything interactive.
If you are trying to play a fast-paced game like Genshin Impact or Call of Duty Mobile via AirPlay, just stop. Don't do it. The input lag—the delay between you tapping the screen and the action happening on the TV—will make you want to throw your phone out the window. For video? It’s fine. For gaming? You need a wire.

Why the Lighting Digital AV Adapter Still Exists
Believe it or not, the most reliable way to how to play an iPhone on a TV involves a dongle that Apple hasn’t updated in years. The Lightning Digital AV Adapter is a weird piece of tech. It’s not just a pass-through cable; it actually contains a tiny ARM chip that encodes the video signal.
Why does that matter? Because it means even if your Wi-Fi dies, your movie keeps playing.
You plug the adapter into your iPhone, run an HDMI cable to the TV, and it "just works." Mostly. There is a catch that people often miss: Netflix, Disney+, and Amazon Prime Video use something called HDCP (High-bandwidth Digital Content Protection). If you buy a cheap $10 knock-off adapter from a random bin at a gas station, those apps will show a black screen. They think you're trying to pirate the movie. Stick to the official Apple one or a certified Belkin adapter if you want to actually watch your shows.
The USB-C Revolution (iPhone 15 and 16)
If you’ve upgraded to an iPhone 15 or 16, everything changed. Apple finally ditched the Lightning port for USB-C, and honestly, it’s the best thing that’s happened to iPhone-to-TV connectivity in a decade.
You don't need a special "Apple" branded adapter anymore. Any decent USB-C to HDMI cable—the kind you’d use for a MacBook or a Chromebook—will work. This connection supports DisplayPort Alt Mode. It can output up to 4K resolution at 60Hz.
I recently tested this with an iPhone 15 Pro Max and a standard LG C3 OLED. The difference in clarity compared to the old Lightning adapter is staggering. It’s crisp. There’s no compression artifacts. If you have a newer phone, this is the gold standard. Just buy a high-quality braided USB-C to HDMI 2.1 cable and call it a day.
Using Your Gaming Console as a Bridge
A lot of people forget that their Xbox or PlayStation can act as the middleman. While the PlayStation 5 doesn't natively support AirPlay (which is still an annoying oversight by Sony), there are third-party apps like "Replica" or "AirBeam" that can bridge the gap.
On Xbox, it's a bit easier. You can use the "AirServer" app, though it costs a few bucks. It turns your Xbox into an AirPlay receiver. This is a solid workaround if your TV is an older "dumb" TV but you have a modern console plugged into it.
Screen Mirroring vs. In-App Casting
There is a massive distinction here that causes a lot of confusion.
- Screen Mirroring: This copies everything on your screen. Notifications, your wallpaper, your low battery warnings.
- Casting: This is what happens when you tap the icon inside the YouTube or Netflix app.
Casting is almost always better. When you cast, your phone isn't actually sending the video data to the TV. It’s just sending a "link" or a command telling the TV's app to play that specific video. This saves your iPhone's battery and lets you use your phone for other things while the movie plays. If you see the Cast icon (the little square with Wi-Fi waves in the corner), use that instead of the generic Screen Mirroring option in the Control Center.
What About DLNA and Third-Party Apps?
Sometimes you're in a hotel or an Airbnb and the TV is ancient. No AirPlay. No HDMI port easily accessible. In these cases, you might look at DLNA apps like "iMediaShare" or "TV Assist."
These are... okay. They are basically the last resort. They work by turning your iPhone into a local media server that the TV can "browse." It’s clunky. The interface usually looks like it was designed for Windows 95. But if you have a bunch of photos or home videos saved locally on your phone and you're stuck with a 2014 smart TV, it’s a lifesaver.
Troubleshooting the "No Device Found" Error
We’ve all been there. You tap the AirPlay button and the list is just empty. Or worse, it shows your neighbor's "Samsung 7 Series" but not your own TV.
First, check the obvious: Are you on the same Wi-Fi? If your phone is on the 5GHz band and your TV is on the 2.4GHz band of the same router, they should see each other, but many routers have "AP Isolation" turned on which blocks this.
Second, restart your phone. I know, it's a cliché, but the mDNSResponder service on iOS (which handles finding other devices) occasionally just crashes. A 30-second reboot usually fixes the "missing TV" problem instantly.
Audio Lag and Lip-Sync Issues
If you are using AirPlay and the person’s lips are moving but the sound is a second behind, you need to look at your TV settings. Most modern TVs have a "Game Mode." Turn it on.
Game Mode reduces the post-processing the TV does to the image. When the TV spends 100 milliseconds trying to "enhance" the colors and "smooth" the motion, it falls out of sync with the audio being sent from the iPhone. By stripping away that processing, the image catches up to the sound.
Real-World Use Case: The Office Presentation
If you're trying to figure out how to play an iPhone on a TV for a work presentation, skip the wireless stuff. I’ve seen too many people stand awkwardly in front of a boardroom while their phone refuses to connect to the office guest Wi-Fi.

Common Myths About iPhone-to-TV Connections
One big lie people believe is that you need an Apple TV 4K box to get 4K quality from your iPhone. That’s just not true anymore. If your TV has "AirPlay 2" built-in (which almost all Sony, LG, and Samsung TVs do now), it can handle 4K HDR streams directly from your phone.
Another myth is that you can’t play protected content (like a rented movie from the Apple TV app) over a wire. You can, provided you have a genuine HDMI adapter. The only thing you can't really do is "mirror" a screen that has a security restriction, like a banking app or certain high-security enterprise apps. Those will just show up as a grey box on the TV for privacy reasons.
Actionable Next Steps for the Best Experience
To get the most out of your setup right now, do these three things:
- Check your TV’s firmware. Go into the settings menu of your TV and look for a software update. Manufacturers frequently update their AirPlay 2 compatibility to fix bugs with newer versions of iOS.
- Optimize your Wi-Fi. If you’re going wireless, ensure your TV is connected to the 5GHz band of your router, not the 2.4GHz. The 2.4GHz band is too crowded with interference from microwaves and neighbors, leading to dropped frames.
- Buy the right cable. If you have an iPhone 15 or 16, buy a USB-C to HDMI 2.1 cable. If you have an older iPhone, buy the Official Apple Lightning Digital AV Adapter. Avoid the "All-in-one" generic cables from Amazon that claim to work with every phone ever made; they almost always fail after an iOS update.
Setting this up correctly the first time saves you the headache of trying to fix it while a group of people waits for you to start the movie. Wired is for stability; AirPlay is for convenience. Choose based on what you’re watching.
