M1 Mac Mini hooked up to a Dell S3221QS 4k monitor: A near-complete trainwreck.

[objectsession]

I'm still having the vertical line problem on my Mac (m2 mini) hooked up via HDMI or DisplayPort with updated os and firmware (which maybe helped some). Mostly just FYI in case anyone is considering buying this monitor or a Mac.

The issue is easy to spot for me by scrolling on this page:

Logic Pro for Mac

Logic Pro is a complete professional recording studio on the Mac. And it has everything musicians need to go from first note to final master.

Still debating returning the Mac mini (can't return the monitor). It's a rare problem, but still annoying problem... but the Mac mini is great otherwise.

I think I can live with it, but I definitely would not recommend buying this monitor to use with a Mac. Especially since the monitor is not exactly stellar in my opinion even without this issue.

After struggling with this as well for months, on 5/22/22, Dell has released a firmware update for the S3221QS Monitor taking my firmware from M2C101 to M2C103.

In the hour since upgrading, my Mac mini M1 has not flickered since! It's connected via HDMI. I haven't tested DisplayPort yet.

I hope this stays the case, has fixed the issue, and works for everyone else!

The firmware update mostly fixed the issue for me but the flickering is back after updating my M2 Mac Mini to 13.3.1. Anyone else?

Did updating to Sonoma fix these issues for anyone else?

I’m on Ventura and once a day mine flickers for about 2-3 seconds and comes back. Good thing I’m patient and it only happens once per day.

I'm on Sonoma and I think it's fixed *knock on wood*. On Ventura, it used to flicker when I scrolled on dark background websites.
