I purchased a video wall from a music store going out of business for $150.00. It consists of the 9, 27" monitors, frame and VGA cables. However, the video wall controller box was sent for repair about a year ago and the manager said it never came back. Does anyone know if a HTPC can be used to split a video signal up into 9 different monitors as separate pictures or one combined picture? As you can see by the price I paid, I am looking for the most cost efficient way to do this. Any help and information would be greatly appreciated!!!!!! Thanks!!!!!!!!!

It can be done in Linux with a combination of Gstreamer and Xinerama. The hard part is getting ahold of enough matching PCI video cards. See photos of a functioning example at the Video Whale page . Read the How-To here . There are also many interesting posts about this project in a discussion at Slashdot . In a nutshell, they used 4 cards per PC, and 4 PCs networked together to make a 4 x 4 set of images.


This is all I know about it...just that it has been done cheaply. I've not tried it myself.

On eBay i've seen devices that can do this for you. They take a signal from a computer or video source, and then split it out for you. I don't remember brands (i -think- Extron has some) or what prices these things went for, so this post is limited in usefulness unfortunately, but hopefully this will help you somehow.

There is also VideoLan


I've never tried it, but I think it involves using a server to dish the full image out into respective streams of each monitor in the grid. Then PCs are used to display a particular chunk to a particular monitor.


It doesn't seem clear if you need 16 PCs for a 4x4 wall or if maybe you could use 4 PCs each with 4 video cards...
