--- Comment #2 from Nate Graham <n...@kde.org> ---
60hz for a 4k screen requires HDMI 2.0 (or later). This means that the GPU,
computer, cable, and monitor all have to support that version of HDMI, or a
later one. If any link in the chain does not, then it will degrade to the
oldest supported version of HDMI, which is likely 1.4. And HDMI 1.4 only
supports 4K screens at 30hz. So I suspect this is what's happening.
Can you check?
