This article (haven't watched the video yet) makes me feel ancient.
Like, it's clearly written by someone who didn't live through the CRT era. It seems to be repeating things they heard but didn't understand and, frustratingly, that includes not mentioning what the actual rating of the monitor is in KHz, which is really the only thing that matters.
I'm old and my knees hurt. That's the only point I'm making here.
