I for several weeks used 1080p/60Hz and thought that everything was smooth, but it is not!
Too in 1080p/60Hz there are Microstutters!
I finally realized that, when I was able to compare the new Pro with the elder Q5, which really plays it nearly 100% stutter free.
It is not 100% but very near.
Meanwhile I am using a player, that does it 100% stutter free, but this is a bit more expensive, compared to the Himedia Players.
