Put some new pictures on my NS-DPF7G frame for the first time in about eighteen months or so. The new pictures I put on the frame look pixellated.
The existing pictures I last put on the frame still look fine, so I can rule out a systemic issue like firmware or hardware.
All pictures I put on this frame (old and new) are formatted in GIMP for Windows to be exactly 800 x 480, or to have only one of the two dimensions be smaller, depending on the orientation of the picture - so they might be 640 x 480 (if I don't want to crop the original) or 360 x 480 (keeping the portrait orientation) or 800 x 240 (panorama-ish). Point being, the frame should not be stretching anything or having to upsize the pictures at all. One dimension is always maxed-out.
All pictures - old and new - have been taken with the same camera. They are all formatted as JPG, with 90+ quality when exported out of GIMP. The same laptop was used to prepare both the old and the new pictures. Original pictures were 3000 x 4000. In some cases I cropped out an 800 x 480 section I liked, in others I selected a portion of the photo with the selection holding to the 800 x 480 ratio, cropped to the selection and resized to 800 x 480. Regardless of the method I used, the output is the same. The pictures look pixellated.
When I view the same picture files I put on the frame (by making a fresh copy off the frame onto my laptop) on my laptop screen, the pictures look as expected - no pixelization, completely clear.
The only thing that's different in my process of creating the picture files is that I upgraded my version of GIMP - from 2.6 to 2.8.
The only differences I've noticed in the EXIF data between the old pictures and the new pictures are:
- ResolutionUnit is blank in the old pictures but set to "2" in the new pictures. I downloaded an EXIF editor and changed it both to "blank" (0) and "not set" (1), reloaded the picture to the frame but that did not make a difference in the appearance of the photo on the frame
- Originally the files were saved with 96 DPI. I changed them to 72 DPI (same as the older, non-pixellated images on the frame) however this resulted in making the pictures load slower, but still pixellated. DPI should have no impact on how an image is displayed on-screen, but maybe this will ring a bell with an Insignia tech.
The questions I have are:
- Would any of the EXIF information I have noted above change how the frame interprets the image? Or is this information ignored by the firmware on the frame?
- Has anyone else experienced this issue? Or did I win the pixellization lottery?
I can attach images (both kinds - older images with no problems and newer ones that don't display properly) if that will help, just ask.
Thanks!
