The native display resolution of 800x600 pixels is high enough to allow a sharp and detailed image reproduction. Brightness and color fidelity are more than adequate. The remote control is with its approx 11cm x 5cm comfortably in your hand.
The forgets the picture frame when disconnecting from the power supply its settings, I could not find the slide show will start exactly at the last frame when the AC adapter is supplying power.
With its screen size of 20,2cm (8 inches) is at the maximum utilization of the area of the screen image size of 16,2cm x 12,2cm (4: 3) possible. In my coming from an SLR images with an aspect ratio of 3: 2, after all, still remains a display size of 16,2cm x 10.8cm or 8,1cm x 12,2cm (portrait format image on cross standing display).
The internal memory is sufficient if the images previously reduced accordingly. In order to have some reserve for the zoom function I resize my pictures on 1024 x 682 pixels. This image size fit about 5500 images in the internal memory. By using a folder structure, the clarity is maintained even in this volume.
I still have withdrawn because of picture frames but is more suited for the desktop, as for the wall unit a star. For this you need but probably displays with more than 25cm (10 inch) diagonal and a resolution greater than / equal to 1024 x 768 pixels.
