Do you have periodic weirdness on the thunderbolt monitor? Every so often, my m1 mini wakes or boots so that there’s a vertical misalignment by a pixel or two about halfway across. It’s like the desktop was cut in half and taped back together slightly crooked.
- alanwreath 6y agoYES -- it's not just me! At first I thought my monitors were somehow broken (which is unfortunate as I paid a bit extra for name brand LG). I suspected something, as each monitor is plugged into an M1 computer (one's a Mac mini M1 and the other a MacBook Air m1). Both exhibit the visual problem you describe on a random basis.
- alanwreath 6y agopairing this with another comment by myself (about multi-monitor support beyond only one external monitor). I wonder if this is the main reason that Apple didn't support more than one external. Does the issue exhibit itself even more when additional monitors are connected? To be clear it never occurs with my main MacBook Air screen (only the external).
- BoardsOfCanada 6y agoJust as a data point, I have an MBP M1 and an LG external monitor and this has never happened to me in almost 6 months usage.
- alanwreath 6y agoI didn't mention this but it didn't happen initially, only after a couple months did the random screen errors happen. And power cycling, disconnecting/reconnecting/changing cables, etc to the monitor changes nothing.
- gwking 6y agoI haev this problem! For me it's a strip about 2 inches wide, down the middle, one pixel higher than the rest of the image. I am using an LG 5k monitor, and I have been unsure if it's a problem with the monitor or the machine. I'd love to know what kind of monitor you are using; this gives me hope that it might be an apple bug that will get fixed eventually.
- meepmorp 6y agoI have an LG 5k, too! And it only happens on that monitor - my LG 4k over HDMI is fine.
- arghnoname 6y agoI also have this problem--also an LG 5K. Disconnecting and reconnecting seems to fix it for now. No idea if it's the monitor of the laptop, but it's the exact same problem and hopefully hardware doesn't glitch in such a consistent way and it can be fixed in software.
- macNchz 6y agoI don't have an M1 machine, but I have had periodic weirdness on external monitors (of every flavor) when waking from sleep on all the Mac laptops I've owned over the last 10 years.
- alanwreath 6y agothat is ... bad luck. Or I have really good luck (having used mac's for over 20 years). This situation is a first for me (and in my case happens during normal usage, ie not upon waking) - though given Apple's recent track record screams buggy software
- dfinninger 6y agoI have this happen on my Windows PC every now and again. It’s on the monitor that’s hooked up via DisplayPort.
- bhouston 6y agoI have run into poor quality DisplayPort cables in the past. I now only buy ones I know are brand name.
- bhouston 6y agoI have zero weirdness at all. It just works perfectly all the time. Neither monitor supports Thunderbolt. But I run off of a USB-C to Display Port cable and one is using the HDMI port. Both run at 60Hz as it is HDMI 2.
- alanwreath 6y agoI run from display port to usb-c adapter -- I wonder if it is my adapter which is a simple Cable Matters adapter (which gets somewhat warm). Be nice if you shared what adapter you're using for comparison.
- jclardy 6y agoI have an Acer Predator that has this issue (Whether using my Mac or PC attached.) Power cycling the monitor makes it go away. Basically the left side of the screen is shifted one pixel higher than the right side of the screen, making a vertical line down the middle where the shift changes.
- alanwreath 6y agoin my case power cycling does not change anything, could be a separate issue for you. In my case it is also retaining a "ghost" of previous pages I've had open. It does eventually go away (and most of the time is not there).
