Question From Laptop to a connected 32 " monitor

[Basteri]

Greetings, Toms group,
I am not getting any younger about using smaller monitors, so I decided to go larger and buy a:

THINKVISION P32 PZ-30 (32 ")
4k UHD/ 4ms / 60hz/ 3840x2160/16:9/IPS /MINI LED

The current laptop to which I connect the 32 "monitor is a:
LENOVO THINKPAD
Intel i7 - 10850 H / 2,70 hz/ RAM 16 GB / GPU NVIDIA QUADRO T 1000

Problem:
When I play specific YouTube videos, the image is blurry and slow. Just not right. However, this does not happen with all YouTube videos.
This is more often than not. The same happens at times with Netflix or any other network. Note that I am connecting to my internet router by cable and using a fiber optics connection, which gives me a minimum of 800 Mbps.

Questions:
Is my laptop GPU, NVIDIA QUADRO T1000, unable to carry the monitor? Should I then replace my computer? If so, what GPU should I get?
Your assistance is greatly appreciated.

What resolution is your Thinkpad set for when using the monitor? It should be set to match the monitor's 3840 x 2160 resolution.

I see; my maximum resolution in my laptop is 1920x1080, so it won't be higher .
Is that the issue?

You may want to consider a laptop that's certified capable of 3840x2160 60Hz to get the full benefit of your monitor.
