Videos falter on the laptop but not on mobile?

DID my internet be too slow. But on my phone I can watch videos on HD and without load times or jerk. In contrast to the laptop, the video loads half, then the video just stops and the sound goes a bit further.

In all cases, this phenomenon occurs. What is the solution?

If your hardware is not suitable for high-definition video on YouTube,

Try lowering the video resolution via the gear icon.

Instead of 1080p stop at 720p or even less.
