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

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
