Also a good way to damage your eye sight given the low refresh rate. One thing I don't miss from CRT monitors from the 90s.

How does a low refresh rate damage eyes? Got a link? Legit question, not looking for an argument.

I have a bunch of computer CRT monitors and the only way to get bad refresh rate that you actually notice is to set them at 60Hz. At 70Hz or above (most can do 85Hz, any good CRT monitor should be able to go above that) you wont have any issues.

Also while this can cause eye fatigue (which depends from person to person), i could never find any proof (and i just did a quick search) that there is any sort of permanent eye damage.

PAL Amiga monitors were the worst with their 50Hz refresh. I'm somewhat surprised my eyes didn't suffer more.

I always worry about what those jarringly bright LED brake lights with a low refresh rate (the ones that leave highly distracting dotted red trails across your field of vision when you move your eyes) are doing to my eyes and everyone else's.

At about the age of 14 I somehow came into ownership of 5" black and white TV. I wasn't allowed to have a TV in my bedroom, but this thing probably looked useless to my parents so they didn't say anything.

Little did they know, while they were at work, I went up into the attic and ran a coaxial cable from a splitter down into my room and into the back of the VCR, all neatly tucked behind my desk. I spliced an old mono 1/8 jack onto an RCA component for the video (ext.ant to VCR) and did a similar splicing for the audio, but I had to run it through an old 8 track player to amplify the audio. It may be obvious that I collected a lot of old junk and cables (I still do).

I did this all so I could primarily watch Conan O'Brien... which was available on channel 4 anyway (accessible via antenna) but I just wanted to watch the show in the highest definition possible.

Having my first kid soon, I'm curious if he'll be as determined to work around the rules.

Yep, been there, done that.

Just knocking up a VGA to composite circuit similar to the one linked below (AD724 chip) to put my laptop onto a 21" Philips colour TV from the 1990s:
