I was wondering if DF, could support those slick screensavers/lock screens like MAC, and Linux. The ones that just BLUR everything on your screen until you unlock. I do not know if it would be implemented as a Lock Screen, or as a screensaver. Currently the lockscreen does not span all 3 monitors, so I am not sure if it would work either way.

Just a friendly suggestion.
Thanks for the awesome product!

I wrote a scripted function to create a blurred image, but I can't refresh it.

It would be nice if BFS.DisplayFusion supported setting the Lock Screen filename and/or refreshing the Lock Screen image. I can't find an API to do that easily in Windows.

Also, my blurring algorithm is running a bit slow - are scripted functions compiled with optimization on?

I got this working from LINQPad by using UserProfile.LockScreen, but it requires .Net 4.5 to be compatible and would only run on Windows 8/8.1. What Windows are you using?

Since DisplayFusion functions are under .Net 4.0, my code won't run anyway, unless I can find a compatible method for Windows 7 and 8/10.

Neato!
I am on Windows 10 1903. So are you saying that if i generate a blurring file to run at screentimeout, i may be able to get the effect I am talking about?

Unfortunately I couldn't figure out a way to grab the automatic or manual Windows lock event (though I am thinking some way to detect idle time and if you know the screen lock timeout, you might could do something close) so you must assign a new hotkey to lock your PC, but then it works if you add a registry key to have windows convert a jpg to the lockscreen.

I sent a share request for the function GaussianLock.

I have modified my function to not lock, added a new GaussianLock function that calls GaussianLockUpdate and then locks, and set a System Idle trigger to 598 seconds then run GaussianLockUpdate. My screensaver timeout is set to ten minutes, so that should catch the screen just before it kicks in.
