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.

No, HDR can’t make your monitor brighter than it is. But it can take full advantage of the brightness and contrast of modern displays in a way SDR cannot. In almost every case HDR looks better than SDR but brighter and/or more contrasty displays take the most advantage.
In a more technical sense, SDR content is mastered with a peak brightness of 100 nits in mind. HDR is mastered for a peak brightness of 1000 nits, sometimes 2000 nits and the resulting improved contrast.
If you don’t watch movies in HDR on a modern TV, you’re not taking full advantage of its capabilities.
