What's the problem with 2K 50Hz screen? Too high resolution?
Lots of 15.6" Windows laptops come with 1080p screen which is painful to look at.

50Hz is a weird refresh rate. Even back to the 80s (and before?) PCs have been 60Hz at a bare minimum.
50Hz is what European power runs at, as opposed to North American 60Hz. This had some correlation to the analog film frame rates being 25 fps in Europe and nearly 30 fps in America, though I’m not entirely sure what the cause was.
Nowadays it’s probably a performance / battery saving “feature” attempt.
TV signals (PAL and NTSC) were 50 and 60 Hz so as to be in sync with the flickering of electric lamps.
When film is converted to 50 Hz TV, the film is sped up 24->25 fps and every frame shown twice. When converted to 60 Hz TV, there is "2:3 pulldown": every even frame is shown twice, every odd thrice. (Actually, both PAL and NTSC have interlaced video modes, with only every other line updated each frame, so as to conserve bandwidth.)
BTW, when 60 Hz computer monitors were introduced in Europe and used in office spaces with fluorescent lights with passive ballasts that flickered at 50 Hz, some sensitive users suffered headaches from using the computer screen for too long. These days, both fluorescent lights and LCD backlights tend to flicker at much higher frequencies that it isn't much of a problem.
Nah, not film rates [1], video: NTSC is 30fps and PAL is 25fps because the cathode ray tube scan rate was built around AC power cycles. When low fps truly Hz. Sorry.
[1] generally 24fps because that is culturally what film looks like and people get very weird whenever anyone tries to fuck with it

FWIW, I had a 4K monitor from 2016 - 2019 that I had to run at 24 Hz due to hardware limitations in a KVM switch. I used this for my day job and experienced no noticeable side effects, even for CAD work. Then again I always disable all animations in my OS.
Standard CRT TV refresh rate in the UK. Pretty much all home computers here produced 50 Hz output, the goal being that they could be connected to a TV, until the PC started to eat that sector in the early 1990s. Games consoles supported 50 Hz (same rationale) until at least PS2/Xbox.
Certainly seems too high for that screen size. But probably not fatal
