It worked and then stopped working (CAC-1170 and mid 2015 Macbook Pro Intel Iris)

Hi. I’ve made all that SwitchRes standard procedure and the CAC-1170 worked fine at 4K 60Hz with my LG 49UH6500 and my Macbook Pro Retina 15 mid-2015. And then… I played a little with the “scaled” feature in Mac OS Sierra display settings and after two or three scale changes it stopped working. Now all I get is a black screen. Tried deleting the custom resolution I had set up in SwitchRes, then rebooting and then setting it all up again, but still nothing.

Any clues?

I would say undo that scaling thing you did and start from scratch. I will ask [email protected] to send you latest firmware for the adapter to make sure that part is “fresh and ready” …
