I have a problem when using Slideshow as it indicates 'Video problem detected'.
I have tried updating the driver without any success.
I am operating on Windows 10 and hadn't had problems until recently.
Has anyone get any ideas.
Switch of the GPU use. That seams to be a miracle cure to most of the problems.
You give very little detail on your system: Lightroom version? Graphic card? Driver version? Windows 10 version (is probably the least problem, because MS forces upgrades)? If you want qualified help, please give a little bit more information.
