I have added your contact information to our follow-up list so that when we have a beta release that addresses this issue you'll be the first to know. We'll be in touch soon, either to collect more information or for testing a solution. ]]> https://www.displayfusion.com/Discussions/View/not-able-to-connect-a-2nd-monitor-error-failed-to-call-setdisplayconfig-hr-31/?ID=d49d23de-b020-489c-ab8b-f0a3d35efffe Sat, 18 Jul 2020 16:25:32 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/not-able-to-connect-a-2nd-monitor-error-failed-to-call-setdisplayconfig-hr-31/?ID=d49d23de-b020-489c-ab8b-f0a3d35efffe DisplayFusion I have two TVs and I am trying to connect them to my Laptop, effectively making a Triple monitor system.

I have connected one tv/monitor directly with the HDMI, and it is working fine.
I am trying to connect the second tv/monitor using the VGA cable, but whenever I try to enable it, I get this error:

An error has occurred while applying your new Monitor configuration.
Please check your settings and try again.
Error: Failed to call SetDisplayConfig. [HR: 31]
[System.Exception]

After reading a few posts here, I downloaded the 9.7.1 Beta 2 version, but to no avail.

I have an old Dell Machine running running an i3-3120M processor along with Intel HD 4000 Graphics (which supports 3 monitors).
OS is Windows 10.

Any help will be greatly appreciated. ]]>
