How You Can Use Multiple TV Screens To Build An LED Wall

LED video walls are undoubtedly all the rage right now. And everyone understandably wants to get the benefits that they provide – from the expanded views to the impressive video clarity. 

But, if you can’t afford a LED video wall, you could instead choose to create a LED screen assembly using different television sets. We’ll explain how in this article.

What Is A Multi-TV Screen LED Wall?

Before we really look into how to make multiple TVs into one screen, let’s take some time to understand multi-TV LED screens and the innovation that comes with them. 

The name pretty much says it all – these are screens that are made with different TVs coming together. Some people refer to these innovations as LED video walls. Whatever you call them, these are simply traditional ways to expand the view of a screen and make it more enabling for audiences. 

If you have a public space or a retail display requirement, then there’s no doubt that a multi-TV wall mount will work for you. They are versatile and flexible, and they can fill so many functionalities. 

So, what is a screen wall made of? Generally, these screens come with the following components: 

The Primary Display Panels 

You can’t have a LED screen without the LED panels, so it should come as no surprise that they play a feature here too. 

A Controller For Content 

Every multi-TV wall mount will come with a LED video wall controller that allows you to keep an eye on the content you’re displaying. The  controller will share signals with each LED panel, allowing you to easily share content across the display. 

A Structure For Mounting 

Your screen needs to be placed somewhere. Depending on the location, you will need a proper mounting structure to help place the screen and hold it firmly off the ground. 

A Stable Electricity Source

Every LED screen assembly needs power. With the right unit, you’ll be able to provide enough power to the screen and ensure that it is perfectly capable of generating your content.

Content Sourcing & Efficient Control

Here, you need to consider two things. The first is the source of the content itself, which you will display to everyone who watches the screen. Then, you need to also make sure that you have the right control measures so that you can change the content whenever it is convenient for you. 

A System For Managing Temperature 

With a 4 TV video wall mount, you’re essentially combining multiple TV sets. This means that you need a system that allows you to take out any excess heat that is generated. 

Instead of just one TV set, this mount combines different units. So, your heat requirements are even more pronounced. This means that you need to prioritize heat management.

How To Choose The Right TV Screen For An LED Wall

Before looking into how to connect four TVs to create a LED wall, you need to first consider a few factors when selecting these walls themselves. 

To that end, here are a few critical factors that need to be put together for your DIY video wall:

Start With Screen Resolution 

Before anything else, you need to make sure that the screen resolution is top-notch. Considering that you’re selecting several screens, you need to make sure that they all support the same resolutions – and that they are set to the same resolution level across the board. 

Watch The Screen Size & Aspect Ratio 

Next, set out the perfect screen size and aspect ratio for the screens you’re looking to work with. Here, it is more than important to consider the available space and the type of impact you’re looking to make with your content. 

Are The Colors Accurate? 

There is a lot that needs to be considered when thinking about how to connect 4 TVs to one screen, and color accuracy is one of those. You need accuracy in color representation, as well as a broad color gamut. 

For things like branding, design, and more, these factors are especially prominent. 

Can The TVs Last? 

Durability is another thing you need to keep in mind when selecting screens. Several screens are being combined into one, and you need to make sure that they are all durable and can last as long as possible. 

What Are The Maintenance Services Like? 

Sure, you can have durable TV screens. But, you need to remember that you’re combining different screens. And as always, you want to make sure that they can easily be maintained when the time comes.

A few other things you need to remember include: 

  • The stability of the refresh rate
  • Proper bezels for optimal visual appeal
  • The screens need to be compatible with your controllers
  • You need to be able to afford them too

How To Set Up A Multi-Screen Video Wall

With everything that’s been said, you’re probably still wondering how to hook up multiple TVs into one place. Well, we’re about to dive into that. 

The Guide To Setting Up Multiple TV Screens For An LED Wall

Now, let’s get to the real meat of the article. If you’re ever wondering how to create a 4-screen TV or how to conjoin 3 TVs on wall surfaces, then this is the exact piece for you. There are usually different ways for you to achieve this, but here is a pretty standard workflow to follow:  

Start By Understanding What You Need

Before anything else, you need to state and define why you’re setting up a video wall in the first place. Do you need something for outdoor advertising? Are you trying to display information to people who are passing by? Do you need a multiple TV setup for sports? What are you trying to do here? 

Understanding this will go a long way in helping you to better define your objectives overall.  

Select Your Display Options

The entire point of knowing what you’re trying to do is so that you will be able to choose the right display for you. There are several video wall display options available, and each of them will be able to meet your needs. 

When choosing, remember to consider factors like brightness, resolution, and others that we have already mentioned above. 

Your Controller Choice Also Matters

Considering that you’re combining different screens, you need to make sure that your controller choice is optimal here. You need a controller that can support the different screens in the wall configuration. It needs to be scalable and flexible, and it needs to be reliable at all points. 

Get A Plan For The Display Look 

Your display layout pretty much considers how the display will look and how it will be visible. As you can imagine, you need to have a proper handle on that as well. 

How are the screens to be arranged? Is it going to be a tiled TV wall? Understand what you’re trying to achieve, and set out to make it happen. 

Mount The Structure & Connect The Displays

From here, it’s all about installing your mounting brackets. Remember – you’re working with a multi-TV mount, so you will need more than one mounting structure. It needs to be secure, and it will need to align with your planned layout. 

Then, connect all of your displays to the controller with the right cables. Like the mounting structure, this connection needs to be solid and secure, and it needs to be in line with the manufacturer’s instructions. 

If you haven’t already, this is the time for you to configure the controller and the layout based on your planned design. Just choose the right resolution and position for each display, and the process should be pretty easy. 

Finish Setting Up Your Displays 

At this point, things should start taking shape. Calibrate each of the displays, so that they all conform to the same settings – for contrast, color accuracy, brightness, etc. 

You can run as many tests as you need to run here, just to make sure that each of the displays is working as it should. 

Secure All Of Your Left Cables 

There’s a high chance that you’ll be working with a wired setup. So, make sure to secure your cables to ensure that there is no clutter and there is no risk of additional damage. If your efforts aren’t enough, then cable management solutions are always there to help you out. 

Remote Monitoring Could Be A Helping Hand

It’s not overly necessary, but if you’re looking to make your operation as seamless as possible, then remote monitoring for your video wall will be an easy banger. This allows you to monitor content, upgrade your screens, and troubleshoot issues all while not having physical access to them.  

Set It Up & Let It Run

You’re all set! Once you have everything done, what’s left is really just the test and a few tweaks if they are necessary. Fire up your screens, and you have your big-screen TV advertising outdoor surface ready to go!

Common Installation Issues & Overcoming Them

When you look to combine multiple TVs in one picture, you’d find that the process is relatively straightforward. But, this doesn’t mean that there won’t be a few issues you might encounter – both as you work through the process and and you make use of your big screen TV advertising outdoor surface. 

Here are a few major issues that might arise as part of this process and strategies that could help you overcome them:

Differences in Brightness & Color Settings

Because you’re working with different TVs, you might notice that they show different levels of brightness and color representations. This could lead to inconsistencies in the viewer experience overall. 

This is why we recommend that you be especially careful in the calibration process to make sure that you get things right before the TVs are installed and combined. 

Issues With Bezel Alignments

If your TVs have bezels – or those borders that exist at the edges – then you need to make sure that they are in proper alignment. Misalignment will cause an uneven appearance, and this will only affect the visual display even further.  

Having To Manage Different Cables

When it was just a single screen, managing cables would have been considerably easier. Now that you have to handle different TV screens at the same time, you can imagine that this issue would be much more difficult. 

To be fair, you could manage the cables on your own and make sure that they are set properly. But, if you can’t, then a cable management system should be able to help set things right. 

Making Sure The TVs Work Together

Compatibility is another major challenge when it comes to how to hook 3 TVs together – or even more screens. You need to make sure that the displays are compatible with each other, and that they all work with your controllers and content sources. 

This is where extensive testing comes in. You need to be deliberate about this step, so you don’t end up with the wrong setup. 

Challenges With Distributing Content 

Considering that you’ll be sharing content across different screens, you might find it difficult to ensure proper synchronization and alignment. To solve this, make sure that you use your video wall features to accurately configure your content and ensure that it can be properly distributed. 

Dealing With Software Interface Complexities 

You might find it difficult to work with the software interface that operates on your video wall controller. Fortunately, proper training should be able to solve this issue once and for all – as well as ensuring ideal compatibility across the board. 

How Will You Maintain Your Screens? 

At all times, you need to keep an eye on the individual screens. If one of them has an issue, then your entire display will be compromised. So, make sure that they are properly maintained and that you have a good handle on them going forward. 


At the end of the day, LED video walls have become the new standard for displays in different ways. At NSE LED Cloud, we can help you to work through combining different TV screens to make these video walls and ensure that you get the right service from them.
