Even old analog CRT computer displays almost never had vertical refresh synchronized with the mains frequency. A CRT at 60Hz flickers very noticeably and irritatingly, never mind at 50Hz! 75Hz was widely seen as the minimum reasonable frequency for long-term usage, and high-end monitors would refresh at 90 or 100Hz.

Digital LCD displays would basically standardize at 60Hz because unlike with CRTs, flicker is not that big of a big problem, and getting LCDs to refresh even that quickly without ghosting or reduction in contrast was a fairly difficult engineering challenge. They're fundamentally DC semiconductor devices anyway, so mains frequency does not matter at all.
What do analog CRT computer displays have to do with this?

My coworkers from the editing and marketing departments would whine all day to me if I ever deliver a 25fps for them to work with, since this format is a nightmare to blend with any 24fps content without introducing very noticeable frame skipping or time demaning tasks to fix it.
Then get a professional film camera and not a consumer camera. I hardly shoot film at all and refuse to pay extra for something I will never use in a CONSUMER camera. Buy a professional film camera like Canon wants you to do it.. Whine about a 5D not having it but stop whining about consumer cameras not having it, as most people will only film family outings without ever doing advanced editing in a PROFESSIONAL setting

Many smaller displays have the power fed to it by a DC adapter (often 12VDC), and the same adapter works on 50 or 60 hz, and from 95 to 250 volts.
