Black bar on top

[pattcz]

Hello i play some 3840x2160 videos and they play nice.
But then i download other 3840x2160 videos and i have black bar on top of the video.

I am using Pot player with madvr filter.

When i try play video on clean VLC install it play nice. (black bars on top and down) But in potplayer i have only one big black bar on the top. Also if i change filter in Pot Player it show on all screen but distorted or with black bar on top and bottom.

I try many things in Madvr settings but nothing work.

Thank you for suggestions.

Some 4K mkv videos have those black bars, you need to zoom or crop. You can try some options in Preferences > Playback > Aspect Ratio. Try "Stretch by keeping AR", disable "Bottom margin for subs" options, if enabled.
