From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

It's mainly for games of course.
It's also good for video, as it can play videos at the highest possible Hz multiple of the video's FPS. So for example 24 FPS video could be played back with 144 Hz, 25 FPS with 125 Hz etc. VRR isn't technically required for this as many non-VRR monitors support different video modes with different fixed Hz as well, but the transition between Hz is seamless (no need to change video mode).
You lost me here now. Why would want to repeat the same frame four or five times in video? Is that to add post processing effects like motion blur between them?
It's not redrawing the frame, it's more related to aligning the monitors refresh rate to the frame rate of the content being displayed. Alignment means your monitor doesn't refresh the screen when the frame is only partially rendered (aka screen tearing).
Right, it doesn't need to be multiples then, it could be the exact same refresh rate as the movie. Even those weird 25.xx refresh rates some are distributed in. Thanks for answering.
Sure could be, but with most VRR displays the VRR range starts at around 48 Hz, so 24 FPS content would play at least at 48 Hz for example.
The lowest multiple is likely what's being used though (I'd have to check), so the numbers in my previous comment are probably off.
