Okay. I already have seen this on my Mac mini 2018, usbc to egpu, hdmi to hdmi. Sounds like I should pick up a usbc-mini display? Or does a minid to minid work?

also does usb-c to minid support HDR?
I don't know the USB-C specs but the monitor, a Dell U2311H is HD and looks just fine, running 1920 x 1080.

It seems usbc and displayport have issues. My hdmi 4k doesn’t. I also have computer sleep turned off but do have monitor sleep turned on. No issues with my Samsung 40” 4k monitor.
Same issue here, I thought it was Catalina, perhaps not.

Its gotten worse with my HP Pavillion 32" after installing 10.15.1
I've submitted feedback per links just above and am now awaiting a support agent via their chat support service. I encourage everyone to also open chats with support as that actually consumes resources when they need physical people to respond...apparently they don't give a crap about our "feedback" any more because their stock price continues to grow

11-12: Awaiting my 4th call from support. This is tedious.

New to this site, not new to Mac. I have the same problem. 2018 Mac Mini i7, Catalina 10.15.1. I've tried two different HP monitors and two different HDMI cables. I usually unplug it and plug it back in, I've never waited for it to clear itself.

Edit-
After my computer was sleeping for about an hour I woke it up. I had the pink screen for 10 seconds, then static for 20 seconds, then the display went back to sleep. When I touched the keyboard it woke up normal.

Hi,
had a similar issues the last week after the upgrade to Catalina.
My Setup: Dell U2718q connected with HDMI to a 2018 Mac Mini.

After boot, no matter a sleep or normal boot the Monitor kept black.
A Mac reset most of the time helped but nor always. The think I'm wondering about is, that the Mac mini wasn't pinagable via lan after the back screen. So it seems the issue prevented the Mac to boot ...

Now I've connected my USB-C Dock from Amazon (Onshida 7 Port USB-C Hub) and it worked directly ... Still with HDMI.

I even tried a fresh install of MacOS - didn't helped at all ...

best
Tim

I have the same issue and always had since I bought the mini in January. Find it completely unbelievable that Apple still did not solve this issue after several macOS updates. What a waste of my time!

Yeah, I'm about done, its a daily annoyance. Apple doesn't give a crap about software quality now that they have Apple TV/Music services cranked up. I'm seeing lots of annoying bugs in iOS Safari too: screen rotate hanging or not recognizing turn, webpages getting stuck, not display banners correctly. They had what, 4 releases of Catalina the first month? I'm in software, this tells me they are building "good enough" to ship then fix it later.

Well, I've had enough and am going to fix it later by taking a hard look at Windows 10. My work Dell laptop has been flawless for a year with all the same peripherals and is 1/3 to 1/2 the price. My wife has S10 and loves it, I'm starting to use Google calendar and email more and more.

Its me, not you Apple. You keep doing you.

Now I'm getting video playback that doesn't work right, it plays at hyper speed, 10 minute video loops in 1 sec....across both Safari, Chrome, using Youtube, CNN, etc. I'm going to box this mini up and take it in, see if they'll give me a new one. Absolutely ridiculous Apple, what has happened to you?

Just got my refurbished Mac Mini. Snow/static has appeared already. Keep it and put up with it or send it back

Send it back. I'm wondering if they've got a faulty part in some batches. They won't fix it until it costs them more than it does us.

Hi, I may have good news for you. I have experienced exactly same issues on my mac.
After some strugling I found that Intel has a "HDMI firware update" that solves this problem.

Only problem is that I didnt bought mac mini this time (although I considered it). I went with NUC device.
I'm quite shocked that not only I saved lot of money for top speced computer, I have actually better working device. Maybe if you load Windows, you can actually upgrade firmware for HDMI. Or at least verify your current version. For more infor see:

Thanks! Well if Intel has acknowledged it and fixed it via firmware, I'd have to think Apple would follow suit...maybe not. I will look at the NUC next upgrade. I'm looking at moving to the Google ecosystem which is hardware agnostic, I've got too much tied up in Apple software/services
