Add 3 screen's to a graphics card that supports two

[aaronyz123]

Hey, I'd like to add a third screen to my video editing setup that is solely for viewing the video's while I'm editing (if you use Premiere you get what I'm saying). The problem is that my graphics card only supports 2 screens and there is no room for another graphics card. The one I have in now has done me well, and it was pretty expensive so I don't really want to replace it. Are there any other options? Thanks.

What CPU is it?
GPU?

plug third monitor cable into motherboard to use both IGPU and GPU. Make sure your main monitor runs off GPU not IGPU.

The motherboard ports have tape over them saying something like "Ports disabled" or something like that. I read somewhere that if a graphics card is plugged in, the ports on the motherboard won't work.

Go to BIOS and see if you can turn on the IGPU in BIOS.

Thanks for the answer but can you please translate it to English?

I am not sure what BIOS/Motherboard you have, something like this: https://www.youtube.com/watch?v=0BoktTdEZFE

Ok, I see what you mean. There is no way it will mess up my computer by pressing f2 a hundred times right?

 

[vapour]

nope, could be F2, could be del, just try.

I tried it and there is an option that looks promising but it won't let me change it.

According to your posted specs, you have a gtx745 4Gb dedicated gpu. According to nvidia specs, that gpu will support 3x monitors, dual link dvi-d - hdmi - vga. To get that to work with modern monitors you'd connect the monitor to its dvi-i port, and either use a dvi-i dongle adapter to vga or use a dvi-i to vga cable. Granted it'll not be the greatest picture being vga standard, but it'll work for the unimportant stuff like websites or MS Office spreadsheets.

Thanks for the replies... it does not have VGA, only one dvi and one hdmi

Eww. You got an OEM special. Those are cards which might have failed original testing in some way, but get sold to 3rd party vendors for cheap. I had a Dell pc with an ATI radeon x800 that was like that. Instead of full reference specs, the buss was chopped by 1 link, so instead of being 256bit, it was 192bit. Couldn't tell the difference until gaming when everyone else got 90fps, I was getting 60fps.

Hdmi and dvi-d are both digital outputs, so what you've basically lost is the DAC for the analog output with the vga. With the way the hdmi/DL dvi-d works, it's only possible to get a single output, so if you used a splitter, you'd only get mirror copies on each leg, no 2x separate outputs like what mini-dp can do. Consequently, you are stuck with only 2x monitor capabilities with that particular gpu.

Which leaves you a choice, stay on 2x monitors or replace the gpu with something like a gtx1030/1050 which will support 3x monitors out of the box.
