Hi Jan,
No, I'm not getting fed up with all this. I'm grateful for all the help I've been given in trying to resolve this issue. I tried uninstalling and reinstalling the Nvidia driver, and that didn't help, I even did a complete removal of Deskscape, again, only this time I reinstalled Windows 11 Pro, keeping my apps and data, and that too didn't work. So as a last resort, I switched both DP ports on my Graphics card, to one DP and one HDMI port on my motherboard making use of Intel Integrated Graphics. "THAT WORKED". However, now I have to find out what the problem with my graphics card is, whether or not it's a setting on the Nvidia control panel, which I didn't touch, or the graphics card itself. Oh, well, I got my animated backgrounds back. Thanks to everyone who took the time to try and help. It is VERY MUCH APPRECIATED!!
Thanks to all,
Butch
