This is probably a configuration problem, but I have tried a bunch of things to no avail. I can show a full sized image on the primary monitor, both those of two of my three secondaries shows something more akin to a large thumbnail. (The fourth monitor is running Starfield). This seemed to work just fine a couple months ago, but I am unsure which beta changed things. I believe I am at the current beta under Windows 7. I am including my troubleshooter and a fraction of the log where I preview the screen saver from settings, then log back on.

A bit of detail. I actually have a wide range of photo sizes. The largest is 9615x3630. The smallest is 1280x1024. Maybe this will help you fix it...

Seems fixed. Thanks.
