I am trying to connect a 15-inch Macbook Pro 2017 to a p3418HW Dell monitor, through a USB-C to HDMI adapter. The monitor shows: “No HDMI signal from your device”.
I have tried the following suggestions on the net, with NO result:
- resetting SMC
- resetting NVRAM
- several times disconnecting and reconnecting power and HDMI cables
I have also tried the cable, adapter with the same monitor with a 13-inch Macbook Pro 2016 and strangely everything works well!!
Any advice is appreciated!
