I was able to get an image to work by setting it to 8-bit linear lighting in grayscale mode, using GIMP, and then saving it as an 8-bit GRAY PNG. This one displays properly when I power off the device. Interesting that it can interpolate for 8-bit images even though the screen is 4-bit. I noticed that it renamed the first image to "bg_ss00.png" when it finally worked.

I made a second image the same way, using the same steps, named it "bg_ss01.png," and saved it to the screensavers directory. However, when this image comes up in the shuffle, it is not displayed. The device instead just shows a black screen. I have restarted the framework, and the kindle, and it still does not display. The image returns the same properties with your preferred tool:

Code:
D:\linkss\screensavers>magick identify bg_ss00.png
bg_ss00.png PNG 1072x1448 1072x1448+0+0 8-bit Gray 256c 502614B 0.000u 0:00.007

D:\linkss\screensavers>magick identify bg_ss01.png
bg_ss01.png PNG 1072x1448 1072x1448+0+0 8-bit Gray 256c 686324B 0.000u 0:00.007
The first one works, but the second one doesn't.
