Need help/advice - the image height is way too big on my tv when playing some videos

Marbah

My setup:
Chromecast 2.0
TV SAMSUNG UE65KU6092
Videostream and a .mkv file. (BDRip x264 AC3.mkv)

When I'm playing the movie its just doesn't fit the screen. The height seems to be waaaay bigger and i'm missing like the whole 2nd line from a subtitle. I've tried from my TV settings to adjust the screen height but I can't shrink it too much.

Any solutions for this?

I have the same issue with my Samsung UA28H4000AFXZA Version ES01. Videostream but with *.mp4 files.
