Firstly go to the Display Refresh App and "Long press" the middle remote button. And, Stop App & clear all the Caches. Then Highlight WMP in Blue again in that Display App.

[b]Settings->video->playback->adjust display

I would use:
Settings->video->playback->adjust display refresh rate> Start / Stop

Also make sure Android Settings > Screen Resolution > is NOT set to > Auto Switch to best resolution.
Set 1080p60hz or 1080p50hz

Thank You for your help.

When You said long press the middle button, is it the home button?, i close all apps but caches where is it?

I clean wmp cache in app admin and change my settings for yours but i have many tv shows and continue play back in a little format.

Thanks
