I have a weird situation on a recently acquired Mac Mini I have twin monitors connected to. One is connected via USB-C to DVI converter lead & the other USB-C to VGA adaptor & lead. The VGA works as expected but the DVI has intermittent snow interrupting the display. It's about 8 seconds of normal display, followed by 2 seconds of snow and just repeats.
I had put this down to the cable being flaky and resolved to get a USB-C to DVI adaptor instead.
Then something very strange happened last night.
I had switched off the DVI screen but left it connected while I did some work in Logic via the VGA screen. I had been working like this for a couple of hours when I opened a window and it opened on the switched off screen so I had to switch it back on to see it.
For some as yet inexplicable reason, there was no snow and I was able to work with twin monitors for another 7 or 8 hours with no issue.
Alas, back to snow when I booted up this morning, despite my futile attempts to recreate whatever magical-faerie-dust circumstances resulted in last night's flawless performance, including leaving it connected but switched off for a couple of hours.
Anyone encountered such seemingly random behaviour before or able to explain it? If I can get an explanation of how to get it working like last night, I won't have to buy any more potentially unnecessary gear.
