RGB not syncing on Commodore 1084 Monitor [SOLVED]

Do you have a multimeter?
Then you can at least check if the cable is wired correctly.

less crappy 1084 models connect via a 23-to-9 pin D-sub connector.

These "less crappy" 1084 die like flies, I have over 10 dead units here with dead flyback.

The older 1084 (with power button at the front) are real work-horses, never had an issue and I use them daily since the 80's (one was used as a bedroom TV for ~10 years).

All 1084 models suffer from crappy power-switches.
I recently bought some replacement switches but they seemed even lower quality than what C= used...

If "modern style" means power-switch at the back - no thanks, that's annoying to me
Never used the monitor built-in speaker, so don't really care if its mono or stereo. It sounds terrible either way!

I did try working with an LCD for the Amiga but quickly moved back to CRT, there's just no comparison in demos & games, IMO.
I'm currently using a 19" Viewsonic CRT which can handle 50Hz, picture looks great & there's zero motion-blur, which is something I noticed on all LCDs I tried.

Able to handle 50Hz mains frequency or able to handle 50Hz display refresh rate?

Refresh rate, of course (I'm in PAL land so everything is 50Hz by default).
I found its quite rare for PC CRT monitors to support vertical refresh of 50Hz.
I also have a 17" MAG model which supports 50Hz, although its manual says the minimum supported is 59Hz.

What I couldn't find was a PC monitor with 15Khz horizontal refresh support, so I had to use a scan-doubler for that.

That may depend on the phosphorous coating in the CRT. I have very well had CRT-TVs with a very high afterglow time and a lot of motion blur by that...

Never seen CRTs with high-decay phosphors, although I know they existed.
It was just a silly idea really, can't imagine it being useful for TV watching or computer use which involves lots of motion, like games.
