I'm surprised no one is talking about the Dell screen bugs with macOS/M1/M2. I have the 27" and 32" curved monitor, and they both suffer from massive flickering issues with some hues.

And yes I have it pegged at 60hz, unlike the "solution" says, removing the variable rate does not solve the problem.

Buyers beware of Dell screens with macOS on Apple Silicon.

And yes I've tried many different cables... :)

I have a LG 38” ultrawide which I would love, except it also has this problem with specific hues. It took me a while to figure out that it was related to certain colors.

I found that if change the color profile I can mitigate the issue, but then it doesn’t look quite as nice.

On the LG, not only is there flickering but a transient burn-in which still appears when the TB cable is disconnected! It fades after a few hours.

Many owners have the same issue with their M1 devices so I assume it’s not something that is fixable.

Is this specific to the curved ones? I've got the Dell G3223Q, a flat 32" 4k 144Hz, no flickering on my M2 MacBook pro or my Framework with PopOS. I run it at 1080p (2x scaling) on both and connect through a CalDigit TS4 w/ DisplayPort.

I like it enough I'm considering a second. Only downside is no usb-c.

It's not specific to curved ones, I have a flat S2721SQ that does it as much as the curved S3221QS.

I believe this is why it's not a problem for you:
