DIY video wall

different methods of creating a DIY video wall.


1. Pointing multiple video cameras at one computer flat screen:




This is my approach, because of its low tech quality. The image quality was surpassingly good. The pixel blended nicely into each other which could be considered as negative. But I liked the look.

2. One computer with numerous graphic cards.




I used this approach for a piece with 6 projectors and it worked ok. The problem is if you do more than just displaying a big quicktime video the computer's performance is slowing down.

3. Scan Converter and VGA Multiplier




The VGA signal from the computer is converted in to a a composite video signal. In order to create multiple different signal you need converters like the MultiPro 2000. They give you the option of zoom in the VGA image and panning to the specific part of the VGA image. Theoretically you could place for small quicktime videos on you desktop, multiply the monitor's VGA signal 4 times with a VGA multiplier and connect one converter to every of the 4 new VGA outputs. Then zoom and pan the converter to the specific part and connect the converter's output to a video projector or TV.

Resolution loss will be a problem with this method and you will need to buy equipment that soon will be outdated.


4. Networking multiple computers and synchronizing their video playback:




I am currently investigating this method using Max MSP and Jitter. Here are some recent video results. One and Two.
