Apple is just awful with external displays in general. I’ve yet to find a monitor/Mac combo that doesn’t have issues. They really need to put some focus into it because Windows really makes macOS look bad in this regard.

Seriously. Even with one external monitor I get things like windows "disappearing" into some in-between land, wallpaper getting messed up... It's shocking.

Like what ? For the past year I've been WFH with the MBP (which has a 5500M gpu) driving its own panel (3072x1920), an external "wide" ~4K~ "Big-ass" (3440 x 1440) and an external "4:3" 4k (3840x2160) No problems here.

  3440 x 1440 isn't 4k, it's an ultrawide 1440p monitor

    Fairy nuff. Substitute "Big-ass" for "4k".

    I’ve also seen them called “ultrawide 2k”, which makes it very clear that it isn’t 4k.

  You’ve gotten really lucky but responses like that make it harder for those with problems to get them addressed. Some of the issues include: screens refusing to turn on, random screen shutdowns (then turns back on), incorrect refresh rate on wake from sleep, incorrect resolution on wake from sleep, monitor position gets reset again on wake, screen image offset on monitor, once detected resolutions and capabilities not detected after restart (hdr, 4k, brightness control), refusing to pass audio through, clamshell mode will keep internal display active… I’m not alone (and this isn’t limited to M1) https://youtu.be/8xwSzFe8CQg https://youtu.be/8xwSzFe8CQg https://youtu.be/OifE32e8Tq8 https://youtu.be/OifE32e8Tq8

    This seems like a EDID issue, I am talking about: "screens refusing to turn on, random screen shutdowns (then turns back on), incorrect refresh rate on wake from sleep, incorrect resolution on wake from sleep, monitor position gets reset again on wake, screen image offset on monitor, once detected resolutions and capabilities not detected after restart (hdr, 4k, brightness control)" And this can be the display itself that's causing the issue. An example that i've found: ```If you suspect that you are affected by this issue, see if you find a reference to YCbCr in the menu of the monitor settings. For the Dell, it was in > Menu > Color > Input Color Format``` Dell (P2720DC)

        This is not what I meant to say. It's difficult for me. And it's what I expected. MacOS or the Display manufacturers treat each other differently in terms of information shared between the display and device itself. I'm talking about EDID. https://gist.github.com/ejdyksen/8302862 https://gist.github.com/ejdyksen/8302862 Not every display, I mean device is built the same. Even if it's the same manufacturer or same device.

  Like what? Display Stream Compression is entirely broken. It worked in Catalina. In Catalina my Mac Pro with a W5700X happily drove 2 4K monitors in HDR10 at 165Hz. In Big Sur my options are now SDR at 95Hz or HDR10 at 60Hz. This has been broken since the 11.0 betas. This happens with multiple GPUs, multiple monitors, multiple interface types.

My MBP (2015/2016, I think) even sometimes hard crashes when plugging in my dual monitor setup (daisy-chained DisplayPort). It feels reminiscent of Windows BSODs from circa 2000 :(

  I get this as well with my 16” MBP at work, my previous work 13” and my personal 13” work fine. So it’s definitely the computer and not the setup

  This is an infuriating bug that impacts my 16" MBP. Everytime I plug into a thunderbolt dock I have a 50-50 chance of a hard reboot due to Kernel panic. There have been threads about this issue for a couple of years now and nothing has improved. I originally came to the MBP from the world of windows and being very jaded by BIOS and sleep issues with my Dell XPS 15. Macs just work they said. Well, jokes been on me. I literally have to constantly mute myself during video calls because my $3500 MBP fans are always whirring away so loudly that it ends up fucking up the audio for others during a call. I've had my entire system throttle and grind to a halt during video calls because of thermal throttling when temperatures got higher during this summer. I'm so over Apple and their laptops. My wife's MBP has a swollen battery that's destroyed the touchbar and touchpad. For all my complaints with Dell, it was nothing in comparison to the pain of owning my MBP. Multimonitor support is a joke. Docks are a joke. Opening apps is a fucking joke due to their sandbox slowing things down to the point that opening any app takes 5-10 seconds. At this point all I do is use my $3500 MBP as a VNC client to my Linux desktop where I get all my real work done. This is the first and last Mac I will personally own. I can see why they were as popular as they were with the developer crowd. But Apple has lost its way and doesn't give a shit, at least not when it comes to the developer / professional users that they originally targeted with their MBP line. I'll be going back to Windows/Linux soon and there is very little I will miss when I make the switch.

    Random thought, when I used the official Apple HDMI adapter, I had no issues. When I used a third party USB-C-DP cable, I had random crashes, especially when turning on or waking from sleep.

It might be awful, but when I use high end PPI, pro color spaces, and move between workspaces with different equipment, sure seems less worse than everything else.
