Nausea with mac screen

These kind of comments aren't helpful -- the poster is not sick; these problems aren't happening on other devices. Maybe other users on this forum have had similar issues, like myself. I'm glad he posted it here so I know I'm not alone. Something's up with the device or the interface.

Dialabrain, you are certainly right that not everyone is equally sensitive, but that doesn't mean that this forum is not the right venue for such a question. In fact, it's totally valid to ask that question in a forum and see if someone else has a simple solution the poster hasn't thought of -- that's what communities like this are for.

Hi srj1002, I bought an iMac 21.5 (Retina display) last week and had the same problem. Let me ask you this: are you using the Spaces feature of macOS? In other words, where you set up multiple desktops and can swipe between them? The visual effect of this is a dramatic sideways motion, and I am beginning to think that my nausea may actually have been caused by this feature and not by the display itself. I'm still testing it but I'm curious what your thoughts are.

It's quite possible certain people are more sensitive to certain screens/monitors. Only an eye doctor would be able to check. Certainly no one in a users' forum could diagnose what is causing it. Millions of users do not get nauseous.

"Something's up" is meaningless.

I apologize; saying "not helpful" was too harsh -- I realize you are trying to be helpful and point the poster in the right direction :) What I should have said is, I think we should be open minded to the possibility that there could be a non-medical solution as well. Discontinuing the use of "Spaces" was helpful for me (another note to the OP: You could try checking the "reduce motion" box in the Accessibility > Display window to get rid of some of the animations)

See your doctor. If the refresh rate on your iMac is causing nausea or headaches, that may be symptomatic of a serious medical problem.

I agree with KiltedTim. You need to consult a doctor, not a forum.

And two people suggested seeing an eye specialist. Sorry if you find that somehow not "helpful".
