Screen Mirroring Guide: Phone or Laptop to TV
Content Team, Jio Mart • 21 Oct 2026
Quick Overview
- Screen mirroring wirelessly duplicates your phone or laptop screen onto a TV in real time
- Most modern smart TVs support Miracast, AirPlay, or Chromecast, depending on the brand
- Android and Windows devices typically use Miracast; iPhones use AirPlay
- A stable Wi-Fi connection significantly improves mirroring quality and reduces lag
- Screen mirroring differs from casting, which streams specific content rather than the entire screen
What Is Screen Mirroring And How Does It Work?
At its core, screen mirroring just duplicates your device's screen onto another display, live, with zero cables involved. Your mobile phone sends out a wireless signal carrying everything on its screen; the television picks it up, decodes it, and shows the exact same thing. It keeps processing this continuously, so if you swipe or scroll on your phone, the TV follows along instantly. Most of this works using Wi-Fi Direct or Miracast, the technology that manages the connection between your two devices.
Screen Mirroring Vs Casting: What Is The Difference?
Here's something that trips people up constantly, myself included the first time I tried it: mirroring and casting are not the same thing. Mirroring shows everything on your screen literally: texts, notifications, and the works, duplicated onto the TV in real time.
Casting is more selective; it sends one specific thing, like a video or a playlist, straight to the TV, often streaming directly from the internet rather than from your phone. That's why you can cast a movie and then go text someone without interrupting playback, but if you're mirroring and a WhatsApp message pops up, everyone in the room sees it too.
How To Screen Mirror Your Phone To A TV
Screen mirroring phone to TV setups differ slightly depending on whether you're on Android or iOS, but neither takes more than a minute once you know how.
How To Screen Mirror An Android Phone To A TV
Here's how to screen mirror on Android, with just the essentials:
- Get your phone and TV on the same Wi-Fi network.
- Pull down Quick Settings and hunt for "Cast", "Screen Mirroring", or "Smart View": the exact wording depends on your phone's brand.
- Tap it, wait a second for your TV to show up in the list, then select it.
- Confirm the prompt on your TV, and that's it: your screen's mirrored.
Screen mirroring Android to TV works surprisingly smoothly on most newer phones, since Miracast is built into Android. No extra apps needed.
How To Screen Mirror An iPhone To A TV
Screen mirroring an iPhone to TV takes a slightly different route because Apple runs on its own AirPlay system instead of Miracast. Swipe open Control Centre, tap "Screen Mirroring", and pick your TV from the list. If your TV doesn't have AirPlay built in, you'll need a compatible streaming box plugged in first. Once it connects, your iPhone screen appears on the TV exactly as it looks in your hand.
Laptop Screen Mirroring: How To Connect Your Laptop To A TV
Laptop screen mirroring runs on the same basic idea, just with a couple of different button presses.
On Windows, hit the Windows key + K, or open the Action Centre and hit "Connect". Pick your TV from the list, punch in the PIN if your TV asks for one, and you're mirrored.
Laptop to TV screen mirroring tends to go smoothest when both ends support Miracast, which covers most smart TVs sold today. On a Mac, AirPlay does the same job instead: just make sure your TV or streaming device supports it first.
What Do You Need For Screen Mirroring?
Less than you'd think, honestly. A decent Wi-Fi connection is the main thing, since most mirroring runs over Wi-Fi, though Miracast can also create its own direct wireless link without a router. Beyond that, your devices just need to be reasonably up to date.
Older phones or TVs without built-in Miracast, AirPlay, or Chromecast support will need a small streaming device to connect them. If you're browsing smart TVs or Android phones on JioMart, most current models already have this connectivity built right in, so there's nothing extra to buy.
How To Fix Common Screen Mirroring Problems
If it just won't connect, restart both devices first and double-check they're actually on the same Wi-Fi network: you'd be surprised how often one device is quietly sitting on a guest network while the other isn't.
Choppy or laggy mirroring is usually caused by weak Wi-Fi, so moving closer to your router or reducing the number of devices using bandwidth usually fixes it. If your TV simply isn't showing up as an option at all, it might not support Miracast, AirPlay, or Chromecast: older TVs sometimes don't. And don't overlook outdated software; keeping your phone and TV firmware up to date quietly fixes more mirroring issues than you might realise.
