VGA From 3 Sources to One Display

[sentryknight]

Hi,

I am looking for an external video card or device that will take video from 3 different VGA sources and converge them into one display feed to connect into an external display via VGA or HDMI for a 3 way splitscreen.

Can anyone help?

No idea, but also might want to get an idea of the cost of just having 3 separate displays simultaneously showing the different VGA sources. Might be cheaper than trying to get them all onto one display.

How does the splitscreen work? What is the orientation? how does it manage downsampling?

This isn't just some electrical connection, you have to have a device that 'understands' the signals, their resolution and bit depth and how to interpolate the lower pixel count, and where to place them on the screen.

I'd wager such a device exists in the context of security cameras, etc, but image quality is probably SDTV resolution (320p). Modern security camera systems use software in a computer to merge the images, which is probably your best bet, but that requires having a 4th computer doing the image splitting.

I agree that having 3 displays would be cheaper and easier.
