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.

- akvadrako 5y agoIt 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.
- rsynnott 5y agoFrom 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.
- akvadrako 5y agoThat'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.
