I am not well-versed with resolution when it comes to display/video, but I am very curious to know if there is any difference between resolution terminology of LCD/LED display/screen panels of television & computer monitors and that of video (movies)? If so, how does it exactly work?

Example: I am confused with resolutions like 1440p (2560x1440) which is used with displays and is known as QHD VS 2160p (3840 x 2160) which is used with videos (and images?) and is known as Ultra HD.

I am sorry if my question is unclear. Thanks for any help.

If you go down enough, eventually they'll all be referencing the number of pixels. The names (esp unclear ones like UltraHD) are now the realm of marketeers, and have long lost any useful meaning. One thing you can generally see is that the resolutions for TV's will generally be 16:9 aspect ratio.

There is a decent list of resolutions, their names, and some history on this Wikipedia page.
