Yes, thanks, - it's working as pictured - on my current 2017 iMac. But will it work with a new M1 iMac??
Can you verify for us so we know 100% what video connector your old Apple monitor has please? I'm guessing it's an ADC connector. Apple released 4 versions of these monitors from 1999-2004...and 3 of them had an ADC connector.
Also...what sort of video adaptor/adaptors are you using currently to get this Apple monitor to work with your current iMac?
If this Apple monitor does have an ADC connector...you probably know that the single cable coming from the monitor carries the video signal, USB signal, and power.
This worked fine when this monitor was used in combination with Apple desktop tower computers back then...since this monitors cable plugged into a video card with an ADC port...and this video port supplied video & power to the monitor.
Later Apple released an ADC Adaptor...that looks like this:
This adaptor supplies the power to the monitor...and adapts the ADC video connector to DVI...allowing these old Apple "ADC" monitors to be used with newer Mac's that used DVI video ports (at the time probably in the 2004-2010 time frame). With compatibility with newer Mac's after this time being a bit sketchy.
As mentioned above...3 out of the 4 versions of this monitor were "ADC"...one of them (I think the oldest one)...had a DVI video connector (which in theory)...would be the easiest to work/adapt for use with 2021/2022 Apple computers.
Please let us know (pictures)...what video connectors/cables you have to allow things to work with your current iMac.
Thanks,
Nick
