I have been trying to hook my 2017 13" MacBook Pro (2 thunderbolt ports, no touchbar) up to an external display but it's not detecting any screen is connected at all. I've tried going via HDMI (USB-C cable to HDMI), tried via VGA (Via a USB-C hub) but nothing. I've tried multiple different screens too (including my TV), tried several different cables... Nothing. Might as well have connected the screens via a piece of string. It would behave the same way.
Options I've tried:
- PRAM reset
- SMC reset
- Uninstalling and reinstalling DisplayLink
- (I believe it should be showing in allow 'Screen Recording' security and privacy setting, but there's no reference of DisplayLink in there.)
- Weird combinations of disconnecting, powering off, reconnecting...
I'm basically out of options. I know the new screen works because I've tested it with other devices. I know all the cables work, because I've done the same with those.
Is this issue symptomatic of a specific motherboard issue, or is there another option I can try?
