HDMI or DisplayPort input required. USB-C adapters and cables need a separate review.
Choose the input before the cable
This profile does not identify a USB-C video input. Use one of the listed HDMI or DisplayPort inputs, with a correctly directed adapter when your laptop has a different video connector.
The 4K60 profile does not approve HDR, variable refresh, gaming modes or a two-screen dock path. Per-input bandwidth and monitor USB settings can change the available mode.
Check the complete setup
The monitor specification establishes its end of the link. Your laptop still needs a video-capable output and enough display streams; an adapter must work in the required direction. A power-delivery wattage is a maximum capability, not proof that every laptop will charge at that rate.
Manufacturer evidence
These are documentation findings, not NYBreaking hardware tests. A successful source fetch checks availability; it does not independently prove every connection.
