I don't even let my screens turn off anymore; these days I get this weird thing where after waking the monitors up the monitor does not get a signal, but if it is plugged in, the mouse jumps around at like 2fps on the main display as if there's some weird interrupt denial of service going on.
To fix this, I have to restart just to use my monitor again.

- thruhiker 6y agoI experienced this issue using an HDMI to DVI adapter from my 2018 Mac mini to a Dell Ultrasharp display. After purchasing a replacement cable that didn't remedy the problem, I discovered that it's a known issue. The fix was to use a USB-C -> DisplayPort cable (using DisplayPort via USB-C alternative mode). It appears that the HDMI port can't be used with a DVI converter. DVI ports have been replaced by DisplayPort, HDMI, and DisplayPort for some time but it was still a disappointment.
