How to get content to play across multiple screens in one video wall display.
ScreenCloud is a great tool for sending any content to any screen. And if you want to send content to multiple screens, across multiple locations that’s easy too. But what if you want to send content to a video wall setup, where more than one screen makes up a single display?
In this guide we’ll talk you through how to use ScreenCloud with video wall displays and everything you need to know.
A video wall is a group of screens, or displays, put together to create one large screen. Even though multiple screens make up the display, content can be used either separately across each monitor, or as one big picture, by splitting content across individual screens.
Video walls are often used in digital signage when the user wants to create a larger display. This might be to garner more attention, to allow a bigger audience to interact with the screen (as shown in the Lenovo use case below), or to allow more room for content displays such as text, presentations or diagrams.
Video walls can be used for a variety of use cases, including events, within retail, corporate offices, receptions, restaurants or more. Basically, anywhere you might implement a single screen, providing you have room, could also be used as a multi-screen video wall display.
Right now, ScreenCloud does not synchronize perfectly between individual devices. This means, for a multi-screen video wall, it’s not possible to simply pair each screen with ScreenCloud and set the same schedule to play. Doing so, could result in a fraction of a second difference due to the variances in individual device’s internal clocks.
Therefore, if you want different content to play across each screen within your video wall, you can use ScreenCloud without any other system required. Simply pair each screen to your ScreenCloud account and set your content to screen to determine what plays in which area.
However, if you want the same content to play as one image, just split into individual screen displays, you need a little extra help.
First, you would need to add a PC to your display with an AMD Eyefinity graphics card or the Nvidia equivalent. This would allow the Operating System to see multiple displays as if they were one. These graphics cards also have multiple (4-6) DisplayPort outputs, so that no HDMI splitting is needed.
Examples of cards you might use are:
The benefit of this method is that you would only need one ScreenCloud license to run all of your screens, as they are viewed as one by the operating system. By loading ScreenCloud on the PC, you will then be able to load one set of content, like a Channel or Playlist and split the content to play across multiple screens simultaneously within a video wall formation.
For customers with video wall setup for up to six displays, we recommend Intel NUCs, as they are easily purchasable and Intel have good documentation on how to set them up. For six displays, Intel recommends the Intel NUC8i7HNKQC, which we currently have in our test lab and also recommend. You can get it from our partner Simply NUC here.
Below, are the 3 steps needed to get an Intel NUC powering two up to six displays to work properly with ScreenCloud.
For something much larger, from a four screen video wall, up to a twenty-four screen video wall display, we recommend using iBase PCs. You can see their digital signage media players (PCs) here. With iBase we recommend getting support from their sales and support teams more directly as setting up such a huge display can be complex.
