So i got my 3 more monitors for my setup for a total of six and was able to hook them up with a single 780ti by enabling the "multiple display" setting in my Bios.
they are set up in this configuration
Win 10 64bit
4 5 6
1 2 3
1,3 BenQ GL2460 24 inch at 1080p
2 ASUS VG248QE 24 inch at 1080p
4,5,6 Dell p2210 22 at inch
1 hdmi
2 DVI Dual link
3 DVI
4 DP
5 DP
6 VGA to a HDMI adapter
i got all the displays working correctly with out to much of a hassle.
my original intention is to run 1,2,3 in Nvidia surround and use 4,5,6 for desktop use. However i discovered that you cannot combine Mobo ports and GPU ports when using Surround.
when i discovered this i had 1,2,3 in surround with 5 (connected to GPU) as accessory monitor. i decided i did not like this and chose to disable Surround.
After Surround was disabled, i had to rearrange (software) the monitors back to proper orientation as Surround always messes them back up in my experience.
however monitor number 6 did not come back. i used windows display settings and ran a detect nothing found. i switched cables monitor is fine when Display port is used but when i switch the VGA cable to a different monitor that monitor has the problems. when i leave the VGA in and disconnect a different monitor it comes back on, but when i reconnect it disconnects the VGA monitor. oddly enough when i unplug number 6's VGA/HDMI cable only the task bar flashes, and if i look at the display orientation when its disconnected the square for display 5 disappears and 6 appears.
it seems maybe there is some shared resource that was being used when all 6 were working initially but once Surround was enabled it seems to changed.
i uninstalled Nvidia software/drivers and reinstalled thinking maybe it would reset something but id did not change.
and yes i turned the computer off and back on.
anyone have this issue before, know of a solution?
Thanks for any help.
