[QUOTE="chscag, post: 1831951, member: 46727"] Actually the connection is Thunderbolt to DVI not the other way around. I wasn't suggesting the connection is bad, what I was suggesting is to try connecting it another way (perhaps to the VGA input on the NEC) or substitute another cable. That would at least eliminate any cable or adapter problem. You could have had a coincidental failure when you installed Catalina. Do you have any kind of backup that you can revert back to Mojave with? Time Machine? clone? [/QUOTE]
