Photos not kept at original aspect ratio despite scaling set to "Keep original"

All my pictures are not being displayed properly. They are stretched to 1920x1080 (16:9)

The original ratio is 3:2

Under photo settings, I have photo scaling set to “keep original”

I am running the latest firmware.

I tried several different screens to see if it was a problem with the screen, but the problem was the same.

Somehow the WDTV is stretching the pics. How can this be solved?

Have you been able to resolve this inconvenience?

Regards,
