I have two ELEFT407 40" 1080p screens and one NS-39L700a12. Windows gives me "unable to save display settings" when I try to enable any third monitor. I'm only able to display thru any 2 at a time.


I have tried to connect the screen in multiple fashions IE

Displayport thru active adapter to hdmi x dvi to hdmi x hdmi
Displayport thru active adapter to hdmi x dvi to hdmi x dvi to hdmi
Displayport thru active adapter to hdmi x dvi to vga x dvi to hdmi
Displayport thru active adapter to hdmi x dvi to vga x hdmi
Displayport to hdmi x dvi to hdmi x hdmi
Displayport to hdmi x dvi to hdmi x dvi to hdmi
Displayport to hdmi x dvi to vga x dvi to hdmi
Displayport to hdmi x dvi to vga x hdmi
dvi to hdmi x dvi to hdmi x hdmi

I have also tried the setup with 3 dell 19" 4:3 with no luck.
I have also tried every setup first screen than duplicated then extend.
I have also tried using 800x600 as that sometimes helps.
I have also lowered from 32bit colour to 16bit.
I have also downloaded software to force triple monitor like "actual multiple monitor" and others.

Display port adapter used

What ports are available on each monitor?

What Ports are available on the 270x?

What ports of the card have you got hooked up to what ports on the monitors?

Do you know the difference between DVI-I and DVI-D?

Tried every possible configuration.

Do you know the difference between DVI-I and DVI-D?

I have the dvi to vga hooked up on dvi white, the port with both digital and analog signal.

No it does not, i'm using a dvi to hdmi cable.

But it works just fine, i can activate any 2 of the three at anytime, just not 3 at a time.
I also tried
Setup
screen1 Dvi-i to hdmi
Screen 2 hdmi to hdmi
Screen 3 display port to hdmi
