Whenever e.g. My sisters watch Netflix, the internet is still very bad (play fps). However, they look over an old television. I still have ne old ps4 lying around which also has netflix, can it be that I have better internet during the video stream due to the ps4? Could it be that old TVs deal with the internet less well than the Ps4?
I don't think the PS4 will help you there, know your problem exactly as you described haha, but that's the way it is.
Neither the TV nor the PS4 can do anything for it, but your internet connection is bad.
In our household 2 Netflix can watch, surf on their cell phones and gamble is still as if everything else is over.
This is not due to the end devices, but to your line.
This has nothing to do with the devices or anything else. Depending on the quality, streaming services require more data volume than others - and for this reason less bandwidth is left over for the game.
You can of course try to reduce the quality of Netflix accordingly in order to reduce the data size or you can decide who uses which service and when.
Alternatively, of course, there's still the option to ask the Internet provider whether a higher speed is possible. )
