Video not playing on screens of 1920px and more

Is there anybody that can explain to me why my intro video doesn’t show/play on 1920px and more screen resolutions? 1920px is pretty much the standard in terms of resolution of desktop screens.

My video is HD 1920x1080.

It plays on all other resolution sadly it is cropped because I didn’t figured out how to shrink to fit… but kind of secondary for me the main problem is that it doesn’t play on 1920px screens and above.

Over 1920px I don’t care if it is a little pixelated, as long as it plays fullscreen.

Thank You all
