Currently Kodi limits fanart resolution to 1080P. Please let us users decide wheter we want to have 1:1 copy of fetched fanart (so no JPG resize and no recompression). 4K TVs/display are popular and resized/recompressed fanart from 2160P to 1080P looks just bad. 
I checked Kodi's Wiki but as I mentioned before there is a limit to 1080P:
So I've poked in Kodi's code and found that imageres and fanartres are kept in these variables: m_fanartRes and m_imageRes. Searching for those vars got me here: https://github.com/xbmc/xbmc/search?utf8...rtRes&type=
Please Kodi devs. Let us users have those beautiful, crisp fanart images on our 4K displays.
Edit: I know that there is one workaround. I can manually swap image after it is cached to thumbnails folder but for hundreds of movies this is no-can-do. Maybe there is some script that will automagically copy fanart.jpg from movie folder and copy it to appropriate thumbnails folder? (until Kodi will let us use higher resolution fanarts).
