Because my Windows 10 laptop is not adjacent to my stereo system, I am using the DLNA feature of Media Center (23.0.73) to wirelessly send the FLAC files stored on the internal SSD of the laptop to a Windows 10 HTPC connected via USB to my stereo system. I then use JRemote on my Android tablet to "control" the HTPC. Everything works great with one exception: the cover art (as viewed on the LCD monitor connected to the HTPC as well as on JRemote) looks shoddy (pixelated, lacking in clarity, etc.).
Now, all of my cover art has been scanned in by hand (at approximately 1400x1400 resolution) and looks very sharp on the laptop (and on the external monitor I have hooked up to it). So why does it look so much worse on the HTPC and the tablet? One thing I noticed is that when I right-click on a given track and select "View (first file)", the resolution of the artwork associated with that track is 400x400. Is this the maximum resolution for cover art when sending files over the network? If so, why does this same album cover show up at full resolution when viewed in "Images"?
