using multiple displays on a computer.
Now ive moved over from a CCTV DVR system to a full blown computer i want to run two screens.
One is the standard monitor and one is a TV screen.
Ideally i want to have one camera on each screen.
The TV can accept RCA video and the usual connections.
My monitor is currently using the monitor port on the graphics card.
The computer still has its own in built monitor port which does not appear to work (overridden by graphics card).
anyone know how to do it??

does the graphics card have a composite output (single phono, yellow)?
assuming you want both the graphics card vga out and the onboard vga outputting at the same time, this is not possible.

the graphics card has only 1 vga and a HDMI. just want to use an old CRT TV with scart/RGA input for displaying the second camera. only way i can see is to use a RGA splitter on the camera input which is a mechanical solution rather than using the computer to do it.

go get a cheap PCI graphics card that has a composite out on it, install the drivers and run it from that.
i used to have a 3 screen setup for my recording studio, run from 2 seperate cards, one PCI and one PCI-E, used to work good, although the graphics wern't as fast on the PCI, but that shouldnt be a problem for a camera feed.

Running multiple graphics cards is always a gamble unless they are the same and the drivers are happy with it due to driver and resource conflicts.
I would suggest replacing the existing card with a new one and getting a CRT pc monitor off gumtree or freecycle.
Going from 576i cameras, to a progressive scan encoding and then back to interlaced for your TV is a bit mad, given that progressive scan computer monitors (which will be higher res and so can do e.g. 4-up monitoring) are so widely available.
