How do you display the same screen on differnt monitors?

Question

I'm doing a little hobby project and I'm trying to think of a way to have 4 lcd monitors display my screen using one dvi port.

Also would I have to make my own driver for said project?

Answer 1

It's impossible to do it on one dvi port without adding some hardware.

Try shopping for some of these splitter solutions.

Unfortunately, for a 4-way split, the solution will have to be a powered unit because of the loss of quality by splitting 4-ways.

Answer 2

There are two ways to achieve this

The first is to buy an additional graphics card - for 4 monitors, you will most likely need 2 adapters with 2x DVI/VGA ports (or use adapters) on each, then simply plug all together and use "Mirror" mode so that all monitors show the same.

However, I would personally go for a splitter, either VGA or DVI, then you will only need one graphics card.
