How to Duplicate TV Screen to Another TV Wirelessly

Are you a bar owner wanting to replicate a football match on all your TVs simultaneously? Or you’re hosting a game night and want everyone to be able to enjoy the action on every screen in the house. Alternatively, you may have set up a cozy outdoor movie night and need to sync the TVs in your living room and backyard. Whatever your scenario, you’re in the right place to learn how to share content on multiple screens simultaneously and wirelessly.

You might think there’s a simple app on smart TVs that can magically sync content from one TV to another, but unfortunately, that’s not the case. While TVs don’t have HDMI or other video outputs, there are still ways to wirelessly send audio and video from one TV to another. This article will explore devices like HDMI transmitters and methods like Chromecast, Miracast, and Apple AirPlay that can help you duplicate your TV screen wirelessly. So, let’s dive in!

Chromecast, Miracast, and Apple AirPlay for Syncing Multiple TVs

First, let’s briefly touch upon the most popular and effective methods to mirror content on multiple TVs: Chromecast, Miracast, and Apple AirPlay. These handy solutions allow you to wirelessly duplicate your TV screen to another TV with minimal fuss. If you’re familiar with these methods, you already know they’re fantastic! We’ll delve deeper into how to use these technologies in Part 2 of this article.

You’ll need some additional equipment to get started with Chromecast, Miracast, or Apple AirPlay. But don’t worry! It’s less expensive or complicated than it may sound. These solutions are cost-effective and user-friendly, especially compared to other methods like using a wireless HDMI video sender/receiver.

Best Method for Duplicating TV Screen to Another TV Wirelessly

Now that we’ve introduced Chromecast, Miracast, and Apple AirPlay as top methods for syncing multiple TVs, it’s time to explore how to use these technologies effectively. Are you prepared to learn more about screen mirroring? Let’s dive in!

Chromecast: If you’re an Android user or have a Google-based ecosystem at home, Chromecast is a fantastic option. First, ensure both TVs have a Chromecast device plugged into their HDMI ports. Connect the devices to the same Wi-Fi network, and then use the Google Home app to set up and control the Chromecast devices. Open the app, click the “Cast” button, and voila! Your screen is mirrored on both TVs.

Miracast: For those using Windows or Android devices, Miracast is a great choice. Many modern smart TVs have built-in Miracast support, but you can purchase a Miracast adapter if yours doesn’t. Connect the adapter to your TV’s HDMI port, and make sure your devices are connected to the same Wi-Fi network. Open the “Connect” or “Screen Mirroring” menu on your Windows or Android device, select your TV, and watch as your screen is duplicated on both TVs.

Apple AirPlay: If you’re part of the Apple universe, AirPlay is the way to go. For this method, you’ll need an Apple TV or an AirPlay 2-compatible smart TV. Connect your Apple devices and TVs to the same Wi-Fi network. Swipe down from the top right corner of your iPhone or iPad to access the Control Center, tap “Screen Mirroring,” and select your TV. For Mac users, click the AirPlay icon in the menu bar and choose your TV. Your screen will now be mirrored on both TVs.

Comparing Chromecast, Miracast, and Apple AirPlay to other methods, like using a wireless HDMI video sender/receiver, reveals that these solutions are generally easier to set up and more cost-effective. Plus, they offer the added benefit of being compatible with various devices, like smartphones, tablets, and computers.

HDMI Video Senders for Syncing Multiple TVs

Now that we’ve covered Chromecast, Miracast, and Apple AirPlay, let’s explore another method for syncing multiple TVs: HDMI Video Senders. These nifty devices can wirelessly transmit audio and video signals from one TV to another. But there’s a catch: you’ll need two receivers for both TVs, and the transmitter must be connected to a video source like a set-top box or gaming console, as TVs nowadays lack video outputs.

Although HDMI Video Senders are an effective solution for duplicating your TV screen, they are not as cost-effective or user-friendly as Chromecast, Miracast, or Apple AirPlay. It’s always good to know your options!

Tackling TV Screen Mirroring Challenges

Understanding that modern TVs lack video outputs and the ability to directly mirror content from one TV to another, or even from a TV app, makes duplicating TV screens a bit more challenging. However, it’s important to note that there will likely be another device involved in the equation. Whether it’s a mobile device, laptop, or a set-top box, these additional devices can make the screen duplication process smooth and seamless. Considering this aspect, you’ll be better equipped to choose the right method and equipment to achieve your desired screen-mirroring setup.


So, there you have it! Chromecast, Miracast, and Apple AirPlay are fantastic options for wirelessly duplicating your TV screen to another TV. They’re user-friendly, cost-effective, and compatible with various devices. Remember to follow the manufacturer’s instructions and ensure you have the right equipment for a seamless screen-mirroring experience.
