I noticed now that when watching something connected by HDMI from the laptop to the television, when there are scenes that are too dark the image is with pixels but connecting with the HDD i dont have this problem

The problem cannot be the HDMI cable because it is the same as I use to play ps5 and the image is always very good and my laptop have a rtx 2060\amd ryzen7 so i thing its powerful enough to play 4K movies or no ?

Yes, ur laptop is powerful enough. U can try to play a 4K movie directly on laptop and verify.
Anyways, HDD is always a preferable option. You can even download subtitles separately from subscene.

Watching from laptop to HDMI cable connected to TV, sounds lot of connections and all. I wouldnt prefer that much of a hassel and wiring for watching TV and movies stuff. I too have PS4 pro, HDMI and all that stuff, but HDD is always a smooth option for me, i just plug it back to my TV and havent faced any issues as such.
