Yeah, I also want 90hz, but when I need to use HDMI on my fairly recent X1 I must choose between 4k@30hz or 60hz and I would always choose 4k.

The banwidth for 4k at 60hz is only now becoming mainstream.

The bandwidth for 4k at 60Hz (HDMI 2.0) has been around for a while. The bandwidth for 4k at 120Hz (HDMI 2.1/Displayport 1.4) is only now becoming mainstream.

It hasn't been mainstream. I have the X1C7, a flagship in 2019 and it only supports HDMI 1.4.

That means when I bought my current laptop, still under the 3-year warranty, I would have had to get something worse to get HDMI 2.0 support, since I compared everything available.

From th'internet, that laptop appears to have a thunderbolt port; you should presumably be able to use a DP1.2 adaptor and get 4k at 60hz. Or _maybe_ a Thunderbolt monitor like the above 60hz 5k one, though definitely check before buying.

That's why I said over HDMI. Sometimes it's all that available, either because it's a TV or due to a missing cable. I find those USB-C to DP cables pretty flaky.

I personally think the sweet spot is 1440p at 60hz. I find with my build, I can maintain that resolution and framerate with graphic settings pretty much maxed out. My friend with a similar build has same resolution, but targets 120hz. Usually gets there, but has a number of games where he is trading graphical fidelity for performance.

you might be the only person that finds 30Hz display usable.

IME even non-techies find 30Hz uncomfortable to use.

It does have some use cases like displaying mostly static content (images or documentation) or even casual videos.

Definitely not my thing too, I'm all in for 120Hz, but it does have some niche uses at 30Hz.

Most movies are still 24hz. People don't mind it – they can interpolate the frames in between better than any tech by far.

Yes but movies are not interactive, and have real motion blur and perfect frame pacing.

Another advantage of a 120Hz display is that it maps perfectly to 24fps, whereas a 60Hz display may introduce motion judder.
