I have both a 4k laptop screen and standard 1080p laptop screen.

Can't see a real difference to be honest. I'd probably have to do a proper test to notice one.

Is this push towards 4k 120Hz comparable to audiophiles advocating for expensive audio gear where most folks wouldn't hear a difference?

Are there any eye health implications using non 4k screens?

The jump from 1080p to 4k is extremely noticeable to most people. At standard scaling you also get way more screen real estate, which is definitely a plus. I also think most people would easily pass a blind test and recognise which monitor has 120 vs 60Hz.

At the size of a laptop screen the difference is not that great between 4K and 1080 but go up to a 24”, 27”, or 32” desktop display and it really jumps out if you are looking at text. If you are mainly looking at games, video, or images then resolution is less significant. Clear and readable text is all about resolution and higher ppi.

Yes - that makes sense. I'm not using those monitor sizes.

Thanks for that perspective.
