Are some of them connected via USB display adapters?

Also, you mentioned that Windows was fully up to date, but are you also running the latest Intel and NVIDIA display drivers? ]]> https://www.displayfusion.com/Discussions/View/bug-with-display-fusion-multi-monitor/?ID=73b7e832-69be-4ff5-8cd7-38c2a7e5b06b#4 Tue, 18 Mar 2014 03:34:05 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/bug-with-display-fusion-multi-monitor/?ID=73b7e832-69be-4ff5-8cd7-38c2a7e5b06b#4 DisplayFusion Hi keith,

I tried to enable use classic monitor get/set functions. I still have the same issue.

An error has occurred while applying your new Monitor configuration.
Please check your settings and try again.
Error: Invalid Parameters [-5]
1. Unknown\\\.\DISPLAY1

Also if I insist to swap between load configuration, it end up detecting only 1 monitor and will fail to detect the other. To fix this, I have to go in windows screen resolution to reenable the monitor.

Another thing I noticed is that the ID of monitor seems erronate. By example in screen resolution monitor are named 1-5 but in display fusion it is named 1-6-7-8-9 ]]> https://www.displayfusion.com/Discussions/View/bug-with-display-fusion-multi-monitor/?ID=73b7e832-69be-4ff5-8cd7-38c2a7e5b06b#3 Mon, 17 Mar 2014 18:05:38 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/bug-with-display-fusion-multi-monitor/?ID=73b7e832-69be-4ff5-8cd7-38c2a7e5b06b#3 DisplayFusion In the DisplayFusion Settings > Advanced Settings window, could you try enabling the "Use Classic Monitor Get/Set Functions" option, then restart DisplayFusion and try again to see if that helps? ]]> https://www.displayfusion.com/Discussions/View/bug-with-display-fusion-multi-monitor/?ID=73b7e832-69be-4ff5-8cd7-38c2a7e5b06b#2 Mon, 17 Mar 2014 00:59:32 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/bug-with-display-fusion-multi-monitor/?ID=73b7e832-69be-4ff5-8cd7-38c2a7e5b06b#2 DisplayFusion Another file to add. ]]> https://www.displayfusion.com/Discussions/View/bug-with-display-fusion-multi-monitor/?ID=73b7e832-69be-4ff5-8cd7-38c2a7e5b06b Mon, 17 Mar 2014 00:58:48 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/bug-with-display-fusion-multi-monitor/?ID=73b7e832-69be-4ff5-8cd7-38c2a7e5b06b DisplayFusion Windows 7 x64 *all latest update*
Nvidia quadro 1000m + hd intel graphics *CPU i7*

Display Fusion version 5.1
Installed version 6.x in case that would fix my issue.

I have a configuration with only one monitor *monitor ID 2 set to primary* to play game.
I have 5 total monitor configured as extended desktop for my workstaiton.

When I load my Game configuration, all other monitor disapear and if I try to load my workstation configuration, it sticks to 1 monitor only. *WIndows screen resolution can still see all my monitor correctly*

If I reenable my monitor with windows screen resolution, display fusion see the monitor again. But if I try to configure them via Display Fusion, I will have an error popup windows appearing with a second popup with the debug information. ]]>
