I have a monitor on a custom made arm that sits above my laptop when I need a second screen.
It works well in a tight space like in a board meeting at a conference table or plane seat. Vertical doesn’t make a real difference in my experience. You just need two spaces that do not move so that you can quickly reference multiple documents and keep your place between them.
I wouldn’t say no gain. I would love that real estate on my bedside stand I use with physical disability. I would not want the sub 17" form factor and keyboard though. I struggle to do anything super technical without a second screen which is a pain in the ass. I can’t sit at a desktop and the ergonomics of a laptop are unbeatable in my situation.
Anything to distract and discredit the guy standing up for principals huh?
HDMI is the proprietary monopoly scam. It is added to devices by the owning members of the scam. Display Port is the open source free equivalent standard that the educated consumer goes looking for.
NVCC is still proprietary and full of telemetry. You cannot build CUDA without it.
