Multiple outputs to CRT TVs

Hi internet!I've got an install project brewing that involves a whole bunch of old school CRT TVs in an array behind a music stage. I'm hoping to have as finite control over them as possible through Izzy. This means that I'm looking to use all 6 stage outputs, but I only need each one to be 640x480\. I'm trying to figure out the best combo of hardware for this setup. Now I could just build a big desktop with 6 cheap little video cards in it, output VGA and then get 6 VGA to composite video adapters to get down to the TV's level. BUT, that sounds like a big pile of mess with a lot of possible points of failure. What I'd ideally like is some sort of specialized video card with 6 composite video outputs via BNC jacks on the back of it. I'm thinking something like that must exist somewhere. Perhaps in the security camera industry?However, I have had no luck finding one. Anyone seen a card like this? Or have other thoughts on how to attack this?Thanks in advance!
I would likely use two Matrox Triple heads to go.each can easily handle 3x 640x480 outputs.You could probably even use a Matrox Dual head to go, with 2 triple heads attached if you only have one Display port out. The total resolution you are after is pretty low, so this shouldn't be to much of a strain.You are looking at 3840 width (640x6), and assuming mini display port, can handle this if running version 1.2" the Mini DisplayPort can drive display devices with resolutions up to 2560×1600 ([WQXGA](https://en.wikipedia.org/wiki/WQXGA#WQXGA_.281600p.29 "WQXGA")) in its DisplayPort 1.1a implementation, and 4096x2160 ([4K](https://en.wikipedia.org/wiki/4K_resolution "4K resolution")) in its DisplayPort 1.2 implementation.
