I have a MacBook Pro and regularly connect it to a Samsung TV via HDMI.
Suddenly, it has stopped working - when I connect the cable the screen looks like it is about to share, then comes back. To my knowledge, I did not run a software update.
I have tried 2 different cables (one with, one without USB-C multi adaptor [not apple], both which worked in the past (and the multi adaptor is recognised when external hardrives plugged in instead) . Tried both thunderbolt ports.
This is clearly a Mac issue. I tried resetting the NVRAM - all that happens is the screen intermittently turns on and off whilst I hold down the keys (is this correct?)
Anyone know how I could fix this issue?? Many thanks!
