Pixel clocks... haven’t thought about those in a looooong time. When my old 14” packard bell monitor world act up i would bust open x11config and taze it with a hilariously overdriven clock.
There was just a kerfuffle about the HDMI output on the Raspberry Pi being able to jam its own wifi at certain specific resolutions. The dot-clock multiplied by the line encoder landed right in 2.4GHz.
As someone who has read lots of anecdotes (but sorely little actual anecdata) about poking CRTs with out-of-range
values and has thus kept well within defined limits for fear of breaking my own stuff... what did this do?
