Mac Mini (M1) 2020, LG UHD monitor flickers on dark colours.

I have M1 Mac mini with a 32 inch LG 4k monitor and the flickering is so annoying

I also tried that and it actually got worse, the lower I set the frequency. Glad at least some people found some workaround though, it's really annoying.

I have the same setup configuration as yours, Mac Mini and the U32R59c display and it’s really getting on my nerves, right after unboxing both, this happens…

I recently I got a mac mini M1 with updated bigsur 11.6 and I have the same issue, I tried differents configurations but I clouldn't.

My monitor is BenQ EL2870U conected with hdmi 2.0

I have such problems too.

I have the same monitors, same problem with shimmering display and thin vertical lines down the screen - its driving me mad.

Same problem. Mac mini M1, LG HDR 4K. Flickers on USB-C

Better, but still happens from time to time.

I also had the same issue with BenQ display on my mini M1. That was very annoying (I changed cables, screen profiles, .....)

So I sell my Mac mini and buy a new MBP 13 M1.....same problem

I have the exact same problem with a DELL S3221QS, which worked perfectly with my previous PC.

It's especially bad when the dark mode is toggled on or when I'm watching TV shows with darker scenes.

I've also tried multiple different cables and connectors, monitor settings etc., but nothing really fixes the issue.

How come this still hasn't been fixed or at least addressed after such a long time? The new M1 Macs made me want to give macOS a chance and I've been really enjoying it, but this issue does leave a bad taste in my mouth...

Amazingly, my M1 Mac Mini and my Philips 4K TV sorted the problem out between each other, without my intervention. I left them connected and running overnight and when I looked in the morning, the problem had sorted itself out. Now have no flickering or black outs and have been able to watch F1 TV on Google Chrome (did not work on Safari), for F1 practice for the Belgian GP at Spa, with no problems. Yes I am very puzzled too. Problems do not normally sort themselves out. Oddly on looking back at the M1 Mac Logs on Console, I found the Mac Mini had restarted itself during the night after a kernel panic and I wonder if restarting the Mac with the TV connected, enabled the two systems to talk intelligibly to each other.

Just to be sure I have the same issue, is yours the same as the video ive posted below? as I was considering returning the monitor as I thought the problem was with that.

I ran the Mac mini through my LG 4k OLED tv and its perfect.

my monitor here is the LG 32UN500-w

im not sure what else to do. should I just keep the monitor?

Thanks! Yea I’m not sure I might have to change monitor too. I’ve tested my MBP 13 (2016) and an Apple TV 4K, and both flicker a small bit, (in the same way, when a certain dark colour palette is displayed, though not as extreme as the Mac mini)

though I’ve only tested them for about 5 mins, and maybe they get worse over time?

anyway, it feels like it could be the monitor. I haven’t tested a non apple product yet.

Same problem with a MBP M1 hooked to an Acer Predator XB281HK 4k60Hz. Plenty people reporting the issue here as well: https://forums.macrumors.com/threads/m1-air-ghosting-flickering-with-external-display.2271670/

This requires an urgent fix IMO. I'm considering returning the unit, my display has been working great with both PCs and MBP for years.

Also, it appears to occur an all M1 machines, be it MBP, Air or Mini.

For my LG 32UN500-W monitor the best solution that I was able to find was to go to displays, and then colors and then use the sRGB IEC61966-2.1 color profile with my monitor on cinema for picture mode. it dose not fix the problem 100% but is the best that I can find, the color accuracy is also not to bad in this settings. I hope they can fix this problem soon. in the mean time I hope this help some of you.
