Sometimes, the Mac would briefly turn on the fans pretty loud for about a second, then perform a hard shut down on its own.

However, after the latest Big Sur update (released a few days ago not sure if this was the issue either?), whenever I hook the monitor into the computer, I get really bad flickering, or a completely black screen on the Mac, along with a green screen on the LG monitor.

I thought it was the LG Display causing the issue, so I hooked that into the iPad Pro via USB-C cables, and the Display has been working fine with the iPad Pro, with no screen flickering whatsoever. However, with the Display NOT being hooked in, the temperature could be over 85 degrees, and the Mac's fans don't even turn on, and the Mac's screen continues to function with no issues, even with it hooked into the Anker Docking Station. Once it got to 85 degrees, the Mac would automatically engage in a kernel task to protect itself, despite my turning on fans and even opening up the window before this happened. Thirdly, one thing I noticed was whenever the temperature (as the office is upstairs) would get above 80 degrees (as this is a work from home solution, where the entire house is running on one air conditioning unit instead of 2), the fans on the Mac would automatically kick in, and get pretty loud whenever the LG Display was hooked in to the Mac. I also had scaled the graphics to be slightly smaller on the LG Display so I could see more data on the screen (maybe this is why? Not sure.). I thought that it was doing that so it could be sure to sync properly with the Mac (which is a 16" MacBook Pro 2020 with Touch Bar). At first, I wondered why that was the case, and to this day, I still don't know why. Whenever I'd be using this 2nd monitor with the new Mac, the LG screen would periodically (say, every hour, then every 30 minutes after a period of weeks) go to a black screen for about a second, then function as normal. Now, I've had this Mac and these systems since September of last year, and I'll admit: I'm using this Mac like I've never used any other Mac I've EVER had, which is at the highest and most intense of all the laptops I have ever owned. There are also 3 hard drives hooked up to the Docking Station, along with the Loupedeck CT, all of which are running with no issues. Also, it is hooked up to an Anker Docking Station (13-in-1), which outputs the sound to my speakers, which are all at least 6' away from the monitor to ensure no interference with the monitor (as I saw on a few online reports that sound interference can cause screen flickering.). As a prerequisite: I have 32GB of RAM, and a 8GB AMD Radeon Pro 5500M Graphics Card that was custom-ordered with the machine. Here we go:īefore the Big Sur update, I was running a LG 27UL650-W 27" 4K UHD LED Monitor with VESA DisplayHDR 400 monitor with no issues.
