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.

I have had this with some laptops if the charger is faulty. The laptop goes into a limp mode, where the CPU locks to its lowest clock speed.
Since the display is using USB-C it may be triggering the slowness. Some USB-C monitors also deliver power to the connected device.
Is the laptop slow, even when running off battery, or only when running off battery?
Keeping an eye on the CPU frequency with something like Btop can maybe help troubleshoot the issue.
That limp mode is usually controlled by 'BD PROCHOT', it can be disabled, but check your sensors and make sure there isn't something wrong before doing so.
