17" ADC Apple Studio Display to iMac
I have a vintage 17" ADC Apple Studio Display I'd like to use as a second monitor to my imac. I've tried every adapter combo I could think of. USB-C TO DVI. Micro USB to USB. USB-C and Micro USB to Micro USB. The monitor comes on for a few seconds then goes into an off-on briefly in a loop. Any ideas before I give up?
