Hmmm no real fond memories
We had a business system that we used back in the mid 90's running OS2.
The system ran using huge Compaq 22" CRT monitors that defaulted to flickery 60Hz and induced migraines to many. The tech department at the time didn't get that stuff.
As I was the 'guy with a PC at home" I was asked to try to sort it out. I dug around and found the 75Hz setting. Odd to find Windows 3.1 tucked away inside. Anyway super! Problem solved...for a couple of weeks and then the monitors started failing like crazy as they couldn't maintain 75Hz at the high res required for a document scanning system.
We were losing 2-3 a week. Ah well.
Biting the hand that feeds IT
