My mac-mini keep losing the connection with my 3rd screen. I went 1.5 years without any issues, but suddenly started getting this bug. Very frustrating as I have to re-boot computer & hub several times for it to correct itself. This time, I’ve been trying to get it to reconnect for hours without success. Changed cables several times to no avail. The screen flashes for .5 seconds before going dark then flashes again 5 seconds later… none stop. The first time this happened, I bought a new screen thinking it was the screen. It worked for 2-3 weeks then started getting the bug again. Now it’s every other day. When I change cables, the main screen goes funky and cycles between images constantly.
