Thunderbolt inputs not working
Hello,
Here’s my systems specs:
- MacBook Pro (Retina, 15-inch, Mid 2014)
- Processor MacBook Pro (Retina, 15-inch, Mid 2014)
- Running OS X Yosemite version 10.10.5
- Memory 16 GB 1600 MHz DDR3
- Graphics Intel Iris Pro 1536 MB
I have 2 external TV monitors hooked into my system, one is hooked in using the HDMI port and the other is using a Thunderbolt port.
Everything has been working great and then, I updated to Catalina and now the ports don’t work. I bought a new cable but that didn’t do it.
It had issues before where I would need to fiddle with the cable and it would work. Now, nothing works. I’ve done all the resetting tips and tricks and nothing works.
Is it possible that both ports stopped working? I’ve always used the first Thunderbolt port and never touched the second one. I tried both now and neither works.
Is there something I can do outside of taking it in to get fixed?
Anything will help! Thank you.
Is this a good question?
Does your internal monitor work without issue?
What does the Display control panel show?
Did you also apply all of the updates for Catalina as well

The internal monitor works great. The display control panel doesn’t even show the thunderbolt attached monitor. Like it’s not even plugged in and yes I downloaded everything for Catalina....I believe. Just followed the steps and did everything it said.
