How to run a wall board of 6 monitors from one PC

I thought you may be interested to see how we run 6 displays from one PC. We built the video wall into our new offices to monitor our network and wanted to find the most affordable solution.

The PC was a custom build a few years ago, of relatively good spec:
  • AMD Phenom II X6 1090T 3.2Ghz
  • 16GB DDR3 1600Mhz RAM
  • 256GB SSD
  • 2x GeForce GT640 2GB Triple Digital
  • A handful of adapters and cables to get all the outputs into HDMI

The TVs are a combination of models due to being expanded from 3 to 6 this year:
  • 2x Samsung 40" UE40EH5000 (middle horizontal)
  • 2x Samsung 46" UE46EH5000 (inner portrait)
  • 2x Samsung 46" UE46F5300 (outer portrait)

We chose two horizontal in the middle for a variety of surface area to display different types of visualisations - horizontal being more suited to a world map.

As the Rise Vision Player does not yet support the concept of multiple Displays on one PC we had to use regular Chrome for each Display and found a program called AutoIT that lets you script regular tasks, including opening programs, moving location and sending commands (such as F11 for full screen).

The script that runs at system boot looks like this:
#Monitor 0,1
Run("C:\Program Files (x86)\Google\Chrome\Application\chrome.exe --new-window http://rvashow.appspot.com/Viewer.html?type=display&id=XXX")
Sleep(2000)
WinMove("", "", -5160, 0, 1080, 1920)
WinSetState("", "", @SW_MAXIMIZE)
Send("{F11}")
Sleep(1000)
#Monitor 0,2
Run("C:\Program Files (x86)\Google\Chrome\Application\chrome.exe --new-window http://rvashow.appspot.com/Viewer.html?type=display&id=XXX")
Sleep(2000)
WinMove("", "", -4080, 0, 1080, 1920)
WinSetState("", "", @SW_MAXIMIZE)
Send("{F11}")
Sleep(1000)
#Repeat times 6

That is about all there is to it!

In the future we'd love to see support for multiple displays on one computer to save us having to run slightly awkward scripts, but it works great for the time being.

I know there are specialized cards that can handle an output to multiple screens.  Using their monitor management software, you can stretch the resolution across all the screens. So instead of 6 screens of each 1920x1080, you'll have a single resolution of 5760x2160 (if it was a 3x2 wall).  Matrox makes several cards that can handle this.

Thanks for sharing!!

Hi Neal,

Yes that's true, however 6 output cards and multi-way adapters can be quite pricey whereas we are using two standard ~$100 cards that do the job quite nicely and also help with the load.

Some of the visualisations we run can be graphically expensive and would really struggle to be rendered by one card.

We did try doing stretched mode with some video wall software I forget the name of, however it couldn't handle us using mixed portrait and landscape. Our layout has a slight offset because the two stacked middle horizontal monitors are taller (2160px) than one portrait monitor (1920px), which gives us an effective resolution of 6240x2160, but with some gaps!

Hi, this is Solmaz, I work in Userful Corporation (a technology base company in Calgary) (www.userful.com) why don't you try our new 4K network Video Wall.
It supports 4K video, 6K HTMI5 and 3D content at up to 30fps
Supports artistic and non-standard layouts including rotation of any individual screen or group of screens to any angle
The solution comes with a free integrated CMS from Rise Vision, but also integrates with other CMSs if desired
Just one Intel Core i7 server can drive multiple, independent video walls up to a total 25 displays, ensuring a cost effective solution
Browser-based control panel enables virtually anyone to setup and configure the video wall in minutes with just a smart phone.
Here is the link to our Userful Control Center Demo http://demo.userful.com/ucc/
and here is a link to

Bob,

I'm going to go ahead and bump this thread, as I know we've had some users asking about display walls recently. Your solution seems economical enough for anyone to get started.

Thanks!
