As an owner of multiple TVs, I know the frustration of not being able to sync them all together. After countless hours of searching and testing, I’ve found the perfect solution to sync multiple TVs wirelessly. In this blog post, I’ll provide a simple tutorial to help you get your TVs synced up quickly and easily. From the basics of setting up your TVs to more advanced techniques, I’ll cover it all.
| Method | Equipment Needed | Steps |
|---|---|---|
| HDMI Cables & Splitters | HDMI cables, HDMI splitter or distribution amplifier | 1. Connect an HDMI cable to your media device. |
| 2. Connect the other end to the (HDMI In) port on the splitter or amplifier. | ||
| 3. Connect (HDMI Out) ports to TVs using long HDMI cables. | ||
| 4. Switch all TVs to the same media device source. | ||
| Chromecast | Chromecast dongles, HDMI and USB cables | 1. Connect Chromecast to each TV using HDMI and USB cables. |
| 2. Set up each Chromecast on the same Google Home interface. | ||
| 3. Cast media to both TVs (may not be exactly in sync). | ||
| S-Video | S-Video cables, S-Video distribution amplifier | 1. Connect the S-Video distribution amplifier to the source device. |
| 2. Connect each TV to the amplifier using S-Video cables. | ||
| 3. Switch all TVs to the correct source channel. |
This table outlines three methods for syncing multiple TVs together: HDMI cables and splitters, Chromecast, and S-Video. The equipment needed and steps for each method are also provided. While syncing multiple TVs wirelessly is more difficult, workarounds like SyncLounge can be used to display the same content on different TVs without cables.

3 Methods to Sync Multiple TVs Together
There are several methods that you can use in order to sync multiple TVs together. Here’s a brief step by step guide for each one of these methods:
1. Using HDMI Cables and Splitters
The first and most convenient method to link your TVs together is by using HDMI cables along with splitters or amplifiers.
For this method to work, you’ll also need a source for the video, such as DVD/Bluray player, a set-top box, or any other device that uses an HDMI connection to display media on your TV.
Additionally, you’ll need to buy a long HDMI cable as well as a good quality HDMI Splitter if you’re only using two TVs in this project.
However, multiple TVs would weaken the HDMI signal, so you’ll need a large distribution amplifier if you want to connect 3 or more TVs at once. Here’s how to do it:
- Start by connecting an HDMI cable to your media device, such as a set-top box.
- Connect the other end of the HDMI cable to the (HDMI In) port on the splitter or the distribution amplifier.
- Connect (HDMI Out) ports with the TVs using long HDMI cables.
- Switch all TVs to the same media device source.
2. Using Chromecast
For this method, you’ll need to connect a Chromecast dongle to every TV you want to sync. Simply connect each device as you’d normally do, and connect them to the same Google Home interface.
For that, you’ll need to connect each Chromecast to their respective TV using HDMI and USB Cables
After that, when you’re casting media, you’d be able to cast both TVs, although they may not be exactly in sync due to individual differences between devices.
3. Using S-Video
S-video is a type of connection that is fairly similar to how old-school RCA connections work. This one allows the transmission of an analog signal from one source to another, which means that it would work best for relatively old TVs that don’t have HDMI ports.
Similar to the previous method, you’ll also need an S-Video Distribution Amplifier in order to create multiple outputs for each TV connected.
After connecting the TVs, make sure that you switch to the right source channel on all TVs.
Can You Sync Multiple TVs Together Wirelessly?
Although it’s pretty easy to link multiple TVs together using the various cables and amplifiers, synching multiple TVs wirelessly can be quite tricky.
This is because the signal coming from an HDMI connection can be too big for a wireless connection to sustain it, no matter how powerful it is.
In fact, a single HDMI 2.0 cable has a data transmission speed of 18 Gbps, which is equivalent to around 2.25 gigabytes per second. HDMI 2.1 is even more powerful with a data transmission speed of 48 Gbps or 6 gigabytes per second.
With that being said, there are a few workarounds when it comes to synching various TVs while streaming or using media players.
Is Screen Mirroring Between TVs Possible?
If you’re using the screen-mirroring feature on your phone you might be interested in applying the same to your TV.
Unfortunately, TVs are built so that they’re mirroring receivers and even the smart ones don’t have the AV output capabilities to become a mirroring source like smartphones, so this option is currently not possible wirelessly.
Workarounds to Sync Multiple TV Wirelessly
Although synching TV using a wireless connection is not possible when it comes to screen sharing and transmitting HDMI-grade signals, there are still some workarounds that you can use to make multiple TVs display the same content without using cables.
The key here is to use a computer or another wireless device as a common link between multiple TVs.
A semi-wireless example here is that you can cast multiple devices at once using your computer by using the previously mentioned splitter to connect multiple screens to a single Chromecast.
You can also use features like SyncLounge, which is presented by Plex and allows you to watch media through different TVs in sync.
Final Thoughts
As you can see, there are several ways to connect and sync multiple TVs together. Ideally, you should consider wired options, because they’ll allow you to connect a huge number of TVs without a huge loss in TV quality.
