I bought an HP df780a4 7" digital picture frame from Best Buy. The example photos on there look great, and some of the photos I uploaded to it look great, but some of the photos I uploaded to it look terrible. It almost looks like the frame can't display all of the colors that are in the photo. The frame has a resolution of 800x480, and I've tried resizing the photos to that resolution in Adobe Elements, but they still continue to display incorrectly on the frame. Does anyone know what I need to do to make my images display right? Thanks!!
