Hi Peter,

The size of the thumbnail artwork that you see on your device may be limited by your device's firmware. From a Mezzmo point of view, the device profile that is assigned to your device in the Media Devices dialog decides the size of the thumbnail artwork that is delivered to your device. We can increase this thumbnail artwork size to whatever size your device can handle. Let us know the name of the device profile that is assigned to your device (see Media Devices dialog) and we'll provide instructions how to modify the thumbnail artwork size.
