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.
