Album cover image quality on Nexus 7

Serviio and Skifta work beautifully together on my Nexus 7 tablet except for one feature - the quality of the album art from the mp3 files. With other media server programs I have tried, the image is large and sharp, but with Serviio it is smaller and indistinct. Serviio Console shows the tablet as an unrecognized device and assigns it the Generic DLNA Profile. Is it possible to edit this profile, or to create a new profile for the Nexus 7, to improve the quality of the images?

Thank you.

try to replace this in the generic profile

  Code:

<ThumbnailsResolution>DLNA</ThumbnailsResolution>

with

  Code:

<ThumbnailsResolution>HD</ThumbnailsResolution>

That did it. Many thanks!
