I will be doing a downgrade and Time Machine restore to Catalina in the next couple days to see if the Big Sur update broke the HDMI port, or if it’s a hardware issue.

Diagnostics Test (result: no issues found).

HDMI monitor not showing up in Display settings.

Unplugged all peripherals except for the HDMI monitor (result: no output).

Confirmed the HDMI cable is fine (it works with another computer and the other monitor).

Upon first boot into Big Sur after the update, one monitor wasn't working (the one with HDMI).

Monitor 2: USB-C/Thunderbolt to DisplayPort I have a dual 4K monitor setup which has worked fine since I bought the computer. I've filed the issue reports a few times, but it feels a bit hopeless.I just updated my Mac mini 2018 to Big Sur, and the HDMI port no longer works.

It is a really disappointing, frustrating issue. I've even had the SMC fail and had to reset it due to this issue, and it affects my work several times a month.

When I switch inputs on my DisplayPort / HDMI display to view my PC desktop, it often crashes - Especially with the DP → HDMI setup/monitor, but also with the play DP cable (this is across two different test displays apart from the Ultrafine).If the laptop goes to sleep, I cross my fingers that it won't break. Other times, opening the lid crashes things.I close the MacBook lid to save a bit of performance since I only use the two desktop displays, but sometimes that crashes things.It helped a bit to stop using the $300 Belkin dock I bought from apple for the Ultrafine, so it is only serving the third display - but issues abound. I have had just terrible trouble with crashes as well on my brand new MacBook Pro this year, but connecting a LG Ultrafine and a Display Port (or HDMI via a DisplayPort → HDMI cable) display results in an unpredictable, crash-prone environment.
