About
A video wall is two or more screens that together show one big picture, each showing a part. Build one with hardware, like a graphics card or a video wall controller that splits the picture, or with screens linked by Daisy Chain, or with cloud software. Here are the options we know work.
Get Started
Hardware
Use AMD Eyefinity
Part of the driver software of AMD graphics cards: Windows sees all screens as one, so no separate player is needed. You need a player with an AMD graphics card. It’s also the most reliable choice, because it bypasses Windows’ window management.
Use Nvidia Surround
Like Eyefinity, for Nvidia graphics cards: it joins several displays into one. See Nvidia Surround for how to set it up.
Use a Matrox controller
The Matrox QuadHead2Go splits one picture over 4 HDMI screens, for a 1 × 4 or 2 × 2 menu board or video wall. It also comes as a PCIe card. You need a separate player.
Link professional screens (Daisy Chain)
Most professional screens from brands like Samsung and LG can be linked through their HDMI ports into one large wall, from 4 to an unlimited number of screens depending on the model. No controller needed, but you need a separate player.
Software
Use cloud software like Userful
Userful and similar services manage video walls online. You still need a small piece of software on the screens, or an HDMI-to-internet bridge, to connect them to the cloud. We haven’t tested every provider.
Stretch the app over two screens (Extend mode)
In our Windows and Linux app settings, resize the window so it spans both screens.
Test it several times: depending on the screens, drivers and system, the app may not come back in the right place after a restart. Eyefinity is more reliable. On Mac (from macOS Monterey) the app can’t span two screens.
FAQ
Do I need a separate player?
With AMD Eyefinity or Nvidia Surround, the computer with the graphics card is the player. With a Matrox controller or Daisy Chain, you need a separate player.
Can I use separate players in sync instead?
Content Synchronization makes screens show the same slide at the same time, but not frame-perfect video. For one big picture, use one of the solutions above.
