Glad to hear that re-saving the Monitor Profiles helped at least! ]]> RE: Mon Config gets error enabling 4th monitor https://www.displayfusion.com/Discussions/View/mon-config-gets-error-enabling-4th-monitor/?ID=63ca9459-b7d0-4b9b-bae5-e4a67e40a733#3 Mon, 09 Jul 2018 16:14:48 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/mon-config-gets-error-enabling-4th-monitor/?ID=63ca9459-b7d0-4b9b-bae5-e4a67e40a733#3 DisplayFusion I'm not sure of the update date to 9.3, but most likely it was an earlier version, since I usually take a previous config, modify and save it.
I have completely recreated it now under 9.3 and it is working OK on 4 monitors.

However, I would still like a procedure to take a config from any monitor and use it to build up a new or modify an existing profile.
I am mainly using 2 computers with 4 monitors each and would like to save a monitor config for each monitor, and then copy a single monitor config into a 4x monitor profile, or move/swap the configuration(s) to a different monitor within a profile. I would also like to copy an individual monitor config to another computer.

I would also like to do the above for Desktop Wallpaper profiles.

I am comfortable with exporting/importing registry chains, if required.

Thanks, Ron ]]> RE: Mon Config gets error enabling 4th monitor https://www.displayfusion.com/Discussions/View/mon-config-gets-error-enabling-4th-monitor/?ID=63ca9459-b7d0-4b9b-bae5-e4a67e40a733#2 Thu, 05 Jul 2018 19:17:31 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/mon-config-gets-error-enabling-4th-monitor/?ID=63ca9459-b7d0-4b9b-bae5-e4a67e40a733#2 DisplayFusion Were these profiles created before or after updating to DisplayFusion 9.3? ]]> Mon Config gets error enabling 4th monitor https://www.displayfusion.com/Discussions/View/mon-config-gets-error-enabling-4th-monitor/?ID=63ca9459-b7d0-4b9b-bae5-e4a67e40a733 Mon, 02 Jul 2018 21:31:15 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/mon-config-gets-error-enabling-4th-monitor/?ID=63ca9459-b7d0-4b9b-bae5-e4a67e40a733 DisplayFusion When enabling Monitor 3 I get:
"An error has occurred while applying your new Monitor configuration.
Please check your settings and try again.
Error: Failed to call SetDisplayConfig. [HR: 31]"

Other times I can get it enabled, but it moves monitor #4 config to Monitor #3 and leaves M4 with nothing configured.
How can I fix the error, or move M4 config back to M3?
Is there a reg key I can change to move profiles from monitor to monitor?
I have attached settings, 180702-4X-Browsing-onM3NOTM4 is the profile that puts config on monitor 3 instead of leaving it on monitor 4.
Thanks, Ron ]]>
