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.

question about laptop docks (feddit.uk)

Is there an actual graphics processing system inside the dock? For docks with two or three HDMI outputs, shouldn't reviews be focusing on the performance of the internal GPU system? Because it's something I've not noticed in reviews if that's the case.

There's no real graphics hardware in MOST docs, but some USB docks labeled display link actually have a little display adapter in the dock that is written into by your gfx card.

Also thunderbolt and to a lesser degree displayport send (or can send and often dont) partial screen updates making the endpoint do some graphics card like work.

Otherwise there are usually chips that convert formats, displayport to hdmi, etc, and logic to handle resolution negotiation which a lot of docks get wrong and leave you with 1080p when you should be seeing 4k.

Anyway yes you're mostly right "But ahkshually!!!"
