I understand that this can be frustrating. But it is not always Apple's fault. Some screens are also not 100% standard and can give strange results.
Nope. This worked perfectly until the Golden Master. All Betas worked fine. Last update to GM also updated the firmware and it ended my USB C screens.

It’s that time again for the next macOS not to focus on new features but instead focus on stability improvements.
You know... I totally agree, but I realized, they can't do that anymore.

Because then people say it's a boring update, that Apple isn't innovating anymore. Without counting that Microsoft is now agile with... well, pretty much everything they do, which is giving some serious heat in Apple's butt.

And the sacking of everyone who carpet bombed the Safari sidebar in macOS and iPadOS. A lot of the issues are simply bad, user hostile design choices. A bug can be defined as unexpected behaviour. Many of the problems now plaguing Apple’s platforms are not unexpected behaviours. You’d have to be asleep at the wheel to allow many of them through the first beta, let alone put them into production. It really feels like Apple just don’t care anymore.
 
I don't know if its display related, but my 2018 Mini has kernel panicked several times for the first time ever after the 12.3 update. I have a Dell 49" superultrawide monitor via USB-C connection.
 
I have had external display issues with my iMac 24" M1 since the start: after every (re-)boot, the via USB C-> HDMI connected 4K TV defaults to "mirroring" and @ 30 Hz.
I cannot change this in the display settings. (Yes, the cable supports 4K @ 60 Hz)

But after disconnecting and reconnecting the USB-C cable once the iMac is turned on, it then does the intended "extend display" 4K @ 60 Hz.

I have not tested macOS 12.3 yet with that Mac. Will do coming weekend.

Well the good thing is you can run the 12.2.1 installer to revert and it will just replace the macOS and not touch your personal files or installed files.
That’s the neat thing about Monterey, your files and the system files are completely separate.

We don’t have to worry about them stop signing the previous installer. Not yet.:rolleyes:
 
What is truly frustrating is that I have reported this issue with Feedback Assistant when it first appeared in October 2021. The issue was fixed in the next beta update, but then returned when 12.3 beta was issued in January 2022 and has not been resolved since. I’m just confounded that they went ahead and issued the public version of 12.3.

My system is an intel Mac mini 2018 and both my monitors are connected by Thunderbolt 3 to DisplayPort. I have tried playing around with different configurations including connecting one of the displays to HDMI but nothing worked. I was forced to downgrade to macOS 12.2.1. My main concern is that my Mac Studio will be arriving in a few days and it will probably come with 12.3 installed.

The problem is definitely with 12.3 because I can run Mojave, Catalina, Big Sur, and Monterey 12.2.1 on dual displays without problems.

I was holding back on 12.3 because of some of the changes to the OS that Dropbox said may cause a few small issues. I'll keep holding back for a while after reading this as I use 4 external monitors with my 14" MBP.

No problems here using a M1 Mac mini connected to an Apple 30" Cinema Display via a USB-C to Mini DisplayPort. Also no problems on a 14" M1Pro MacBook Pro and Apple XDR Display.
 
This has been an issue with Macs and external displays for years. Welcome to the party. I've had the problem with 2 LG 5K's and one Pro Display XDR, monitors you'd think would be bulletproof from this sort of thing, as they are 1st party/semi-1st party displays. I've always assumed it was a Thunderbolt issue.

There have bound to be various issues before now, but this is a 12.3 issue with DisplayPort

Ha, same!! And I am annoyed, because it’s obviously some firmware update that caused it. My thunderbolt connected screens all work but my dual transportable screen setup is bust. So stupid.
 
I've had external monitor issues for years with so many different Mac + monitor combinations I've lost count. Even Apple monitors don't work correctly sometimes - my old 24" Cinema Display showed a line of funky flashing pixels at the top when plugged into my M1 iMac. I swear not a single person at Apple actually uses an external monitor. So I didn't think twice when the Menu bar started appearing scrambled when my 1080p Dell external woke from sleep. I also think 12.3 has caused HDMI hot plugging to stop working with my 2014 mini - to get anything to display requires a restart.
This is the problem. Apple probably don’t use (and don’t test) anything but the most basic factory configurations. We can only determine this by inference, but it’s a pretty loud and clear signal.
 
Since Monterey 12.3, I have noticed some odd behaviour in Microsoft Word. (I have 365 and it is up-to-date.)

The position of the cursor on-screen is wrong. Sometimes it just seems to be at a position a few characters left or right, or lines up, or down, from where it should be. If I type, the characters might appear in the wrong place, or not at all. Just have to page up then down, and it resolves.

As it is so easy to (temporarily) fix, it isn't a major issue. I find the characters in the wrong place, or not present, and have to make a minor correction.

It appears to be a miscommunication between macOS/display driver and Word.
This should not happen because of a display driver, if Microsoft is making Office via the Mac OS APIs...

This is why I am still staying at Catalina. Very stable and works great with my external Cinema Display monitor.

Also, no bubbly UI.
Stable? My GF’s MacBook Pro 13” from two years ago, at the last Catalina release, just spontaneously crashed yesterday while she wasn’t doing anything on it. BridgeOS was right there in the crash report title...
 
My uncle had an HP display with his old Mac mini. Had issues going to sleep. Would often immediately wake up. Not running Monterey.

So we get a new Mac mini and an Acer display last week and we have the same issue.
I’ve never seen a computer that doesn’t suffer issues with sleep mode. Either all the time or occasionally.

good lord, you're all over this thread making excuses. is tim paying you per post?
 
Updating macOS these days feels like playing Whac-A-Mole. Against your better judgment you keep doing it in the hope they fixed some bugs and comedy design choices, only to find they just added even more. Rinse and repeat. It’s kinda like an abusive relationship ?
This is EXACTLY why I stopped using PCs and Windows for anything other than gaming.

I left that platform for the better one, during the golden age of Apple (Snow Leopard, iPhone before 2013)... and since 2013, the better platform has been continually spiraling down to PC/Windows levels of inconsistency, unreliability, and abusiveness.

Apple need to stop pushing new features and fix the goddamned existing software.
 
I just have a generic Dell U2718Q monitor as my external display and it works fine with an HDMI to USB cable with no adapter at 60Hz.

15.6" 2018 MB Pro on 12.3.
 
Strange – my impression is the exact opposite. Before 12.3 I sometimes had trouble getting the external display connected via USB-C to turn on when waking the M1 MacBook Pro I have at work – especially if connecting the display while the computer is asleep and then waking it. Has been working reliably since 12.3 and I updated on the day it was released.

Edit:
Just because of that I had my first problem with this just now. External display wouldn't lit up. Had to remove the USB-C cable connected to the computer and remove it again for the external display to come on.
