Triple monitor setup, 3rd monitor wont work

[Jamesberry101]

Hey I recently bought a third monitor for my computer I have 2 samsung S27D590's and the New one is a Samsung CF591 all 3 monitors work with the computer and all three cables work. My graphics card is a gigabyte geforce gtx 1070 xtreme and it has 5 ports 1 hdmi, 3 display ports and a DVI. The first hdmi and first display port work, but the 2nd and 3rd displayports don't no matter what configuration. I took it back to where they bought it from and they said the graphics card is fine.... please help?

I'm running
Windows 10
On a i7-6700k cpu
Z170m motherboard

Try using a dvi cable, hdmi, and display port.

It doesn't have a DVI port, would a displayport to dvi cable? I don't understand why it doesn't work as it is?

 

[chef7734]

What do you mean it does not have a dvi port? The card does have one. Because many cards require using the DVi and the display port together to use triple monitors on one card.

Ok yes I will get a cable the issue is my monitors don't have a DVI port would a hdmi to dvi cable do? Or displayport to dvi?

I think it's weird it would have 3 display ports if it couldn't take three inputs from them?

 

[chef7734]

You tried all 3 display ports together without adapters? Just display port cables? When you throw the hdmi in there is when it gets complicated. Theoretically all 3 dipsplay ports should work or dvi, hdmi, and display port.

Ok i might get a couple of cables and see what works, thanks!

If you plug all three monitors in originally, the way you intended it:
-Right click on your desktop
-Select display settings
Do you see 3 displays under "customize your display"?

 

[Jamesberry101]

No only 2 monitors, it won't show up in device manager and I use the Nvidia control panel to "rigorously" search for a monitor that didn't work either

 

[Jamesberry101]

I picked up another displayport to hdmi cable and connected all three monitors using the displayports on the graphics card with no luck, will try getting a hdmi to dvi cable tomorrow and see if that works

Why not just use a standard dvi cable? Read this thread with the same issues.

I would but my monitors don't have a DVI port in any of them?

Turn off your computer. Leave the monitor that's not showing up, plugged into your graphics card (In the exact same port). Unplug the other two monitors that ARE working. When you turn your computer back on, do you see any video?
