Until you tell us something about your laptop how are we supposed to know

You're laptop has 4K display? You have sufficient bandwidth to watch the videos in realtime? You have sufficient CPU/GPU power to decode the videos in realtime?

[hello0]

Intel Core i7-4510u cpu,
2.00 Ghz, 8 GB Ram
yes i do have bandwidth.
Where can i find out if it has a 4k display?

that is the info on your cpu
max res is 3200x2000@60fps
no 4k
as for the 1080p60
your bandwidth is getting throttled or your system is having problems decoding the video

[hello0]

do i need more dsl speed?

[gonca]

What is your speed now?
<sarcasm>like pulling teeth from a shark<sarcasm>

[hello0]

16mb

[gonca]

Might not be enough
Without the details of the videos can't say for sure

[jagabo]

16mb

DSL, 16 Mb/s? Doubtful. Try http://speedtest.net to see what you're really getting. And just because you're getting 16 Mb/s from some server near you doesn't mean you'll get 16 Mb/s from Youtube's servers. Your ISP could even be downgrading speeds from Youtube to cut down on congestion.

Also, download some of the videos from Youtube and see if you can even play them smoothly locally.

If you want to play 4K videos, you not only need fast download speed and a fast laptop, but you also need to be streaming from a site that can serve 4K video without interruption.

One other thing, and this may be the most important of all: you need to use the right software video player. There is a HUGE difference in performance between various software video players when attempting to watch 4K videos, either streaming or those stored on the hard drive (or SSD).
