Get the most out of your digital signage network with the biggest and boldest way to display your content.
TelemetryTV allows you to use displays in creative ways to deliver your content. One of the most exciting ways to take advantage of digital signage is to set up a video wall. A video wall consists of multiple screens placed together and operating as one large display.
With video walls your content can be displayed at much higher resolutions than any individual displays. They can achieve enormous display size, retaining message clarity from almost any distance. With TelemetryTV, there are a few ways to set up a video wall depending on the hardware you possess. In this article, we will walk you through the best ways to get started.
We recommend ensuring that you are using commercial televisions to display your video walls. Commercial TVs often give you more control over things like signal splitting and the ability to daisy chain. This is important when controlling your final output. When using consumer-grade televisions we cannot guarantee you will get the output you need.
The traditional way to set up a video wall is to implement a video splitter. These are also called “matrix switchers”, “video wall controllers”, “signal switches”, or some other combination. Video splitters are hardware that take in several inputs and then output them to displays in a controlled way. This allows you to split one signal, or organize many signals, among displays how you choose.
While this gives you a lot of control over how your content will be displayed, video splitters can be expensive. $200-300 can be expected for a 4-input HDMI splitter, and $500-600 for an 8-input splitter or small 4K splitter.
Make sure that the outputs/inputs of your video splitter match those of your media player and displays.
Remember that you can only display the maximum output resolution of your media player. So if you are outputting a 1920x1080 signal from a device onto 4 screens, each screen will only display 480x270. Keep this in mind, as it can make your content look unintentionally blurry.
One of TelemetryTV’s most powerful features is the ability to run any resolution you choose. You are only bound by your hardware and displays. As long as you have capable hardware, you can make your video walls as high-definition as possible.
Keep in mind that the higher resolution you use, the more power will be required from your media player. There will reach a point where your devices simply cannot keep up with the processing demands without introducing lag. Make sure to test any setup first to ensure it runs smoothly.
Remember, the breadth of your options will be limited by the operating system of your media player. Windows 10 devices come in many specifications. You can find options with many more display outputs than ChromeOS devices. Graphics cards are available that are specially designed for video walls such as the AMD Eyefinity.
ChromeOS on the other hand is a much less video-wall-ready option. ChromeOS devices may have up to 2 outputs that are not designed to be run simultaneously. If you wish to run a video wall using ChromeOS, a video splitter is the best way to accomplish this.
Make sure that when using ChromeOS, you have “Enable Unified Desktop” turned ON in Google Admin. To do this, navigate to Device Management > Chrome Management > App Management > Kiosk Settings.
Using commercial televisions, you may daisy chain your video signal across as many displays as you like. By connecting your media player to the first TV, and then from the first to the second TV, you create a daisy chain. You can send the same content to as many TVs as you wish without incurring more hardware strain. Many commercial TVs have rudimentary controls for how to display content delivered this way. However, you may have to deal with each screen displaying the same image repeated.
TelemetryTV’s unlimited resolution makes it the ideal platform for creating stunning video walls. It is best to identify whether video walls will be a part of your messaging from the start. This way you can build your infrastructure with the with the required hardware. If video walls are your focus, Windows 10 is a must. Equipment like custom video cards and video splitters will go a long way in improving your video walls. With the right setup, a video wall will make your content look the best it can be.
