For a change as I prepare for another night's sleep I have no aches or pain in my left shoulder & upper arm. No drugs or special creams used, either. Simply heat, heat with vibration and vibration alone from a mains-powered hand-held massager have combined to put me in this relaxed state. 
‘I’ before ‘e’ except when weighing, surveilling or reimbursing either a seized caffeinated deity or a heinous seismic poltergeist on a heifer whose neighbour reignited eight feisty foreign sovereign atheist reindeer after a heist. That’s weird…
@jextxadore Looks liken there is something hinky with the TB3/DVI adapter: I'm no longer getting the ghosting issues now that I'm using the USB 2 DisplayLink adapter.
@jextxadore Same problems when hooked up to a TB 3-fitted MacBook Pro. I'm about to try using a USB 2 DisplayLink external video card.
Damn. We’re back in lockdown for six weeks as of midnight tomorrow. Residents in affected areas will be barred from leaving their homes for any purpose other than work, food, exercise or medical care. Retail businesses will remain open subject to density limits, markets will be for food and drink only and hairdressers will remain open.
The results are in, I have failed my Covid-19 test. They were looking for evidence of the virus & didn't find any sign of it in my samples.
@jextxadore The monitor has a cable that attaches to a computer via DVI, USB 2 & FW 400 (there are 2 FW & 2 USB 2 ports on the back) & the power connection is DC via a transformer pack which has a low-profile power connection. From the iMac, I used a direct Thunderbolt 3 to DVI adapter. The two PowerBooks are a bit different, the 15-inch has a full DVI port, the 12-in uses a mini DVI to DVI adapter cable.
So apart from the way DVI connects to the various Macs used, yes, the same cable was used in all cases.
@phoneboy Yep, my playlists sync just fine across three Macs & five iOS thingies, although two of the latter have been decommissioned as newer versions of the same type were bought.

@jextxadore I moved it back into the loungeroom & attached a pair of G4 PowerBooks, and each worked just fine, no trace of ghosting.
