@woland 

it's 16sec

@tasglyk

I always see that the video player a little bit for the end stop.

 the easiest solution is to add a few black frames to your video.

@tasglyk

How long is the video?

@mark_m I tried both Hap and h264. It's the same.

@tasglyk

What codec is your video using? H264? HAP? Quicktime? etc etc

Hello I'm trying to play a single video without loop and it stops a few frames before the end.

Any Ideas?

@dusx

I have so much to do until the end of the month that I can't try. I'll get back to you as soon as I can. Thank you so much for your fantastic work

Best regards,

Updating the info... I'm now testing the M4 MacBook Pro, and it behaves exactly the same. The DP doesn't display any images, and the SE has a glitch. And you can't change the Hz on either.

Thanks !

Dear @dusx thanks for you fast response...

We've already tried SwitchResX and betterDisplay without positive results... We think it's an OS and Hz compatibility issue. Does any of this sound possible to you?

Now we're going to try it with an M4 MacBook Pro to dismiss out options

Thanks a lot !

Best,

Maxi

I haven't experienced this, sorry. 
Perhaps a display management utility might help you get the compatible settings. (not the tool I was looking for... another has X in the name I believe and has been posted about in the forum in the past)
