The F21 key registered this time.

If you exit the Elgato software, then run it as admin, does that make any difference? ]]> RE: F13+ Function Keys Can't Be Assigned As Hotkeys Anymore https://www.displayfusion.com/Discussions/View/f13-function-keys-cant-be-assigned-as-hotkeys-anymore/?ID=019c3c4c-4871-7269-9b3d-170e8e753949#6 Mon, 09 Mar 2026 02:40:04 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/f13-function-keys-cant-be-assigned-as-hotkeys-anymore/?ID=019c3c4c-4871-7269-9b3d-170e8e753949#6 DisplayFusion Nothing is happening. ]]> RE: F13+ Function Keys Can't Be Assigned As Hotkeys Anymore https://www.displayfusion.com/Discussions/View/f13-function-keys-cant-be-assigned-as-hotkeys-anymore/?ID=019c3c4c-4871-7269-9b3d-170e8e753949#5 Wed, 18 Feb 2026 16:06:06 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/f13-function-keys-cant-be-assigned-as-hotkeys-anymore/?ID=019c3c4c-4871-7269-9b3d-170e8e753949#5 DisplayFusion Is there an error appearing when you try to set the hotkey in DisplayFusion, or nothing is happening? ]]> RE: F13+ Function Keys Can't Be Assigned As Hotkeys Anymore https://www.displayfusion.com/Discussions/View/f13-function-keys-cant-be-assigned-as-hotkeys-anymore/?ID=019c3c4c-4871-7269-9b3d-170e8e753949#4 Mon, 16 Feb 2026 00:00:42 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/f13-function-keys-cant-be-assigned-as-hotkeys-anymore/?ID=019c3c4c-4871-7269-9b3d-170e8e753949#4 DisplayFusion Looks like the log got replaced with the screenshot in my previous reply.

Also attached a screenshot showing it is configured the same as my other hotkeys that do work at triggering the monitor profiles I setup years ago. Thank you. ]]> RE: F13+ Function Keys Can't Be Assigned As Hotkeys Anymore https://www.displayfusion.com/Discussions/View/f13-function-keys-cant-be-assigned-as-hotkeys-anymore/?ID=019c3c4c-4871-7269-9b3d-170e8e753949#2 Fri, 13 Feb 2026 18:31:04 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/f13-function-keys-cant-be-assigned-as-hotkeys-anymore/?ID=019c3c4c-4871-7269-9b3d-170e8e753949#2 DisplayFusion I tested it here and it seemed to work fine, could you send me a copy of your troubleshooting info?

None of the function keys from F13+ are registering anymore when trying to set as a hotkey.

The F22-F24 hotkeys I made a long time ago have been working fine throughout all the DisplayFusion updates and still do to this day for triggering my monitor profiles, but I just realized that I can no longer register them as hotkeys anymore. Is there an explanation for this? ]]>
