The USB-C ports of the Zenbook 14 OLED support the output of an HDMI signal, but not directly via the USB-C port itself, but by using a docking station or an adapter.

- The Thunderbolt 4 ports available via the USB-C ports support up to 40 Gbps data transfer and can also drive external 4K UHD displays.
- With a compatible docking station, such as the ASUS USB3.0 HZ-3B Docking Station or the ASUS Triple Display USB-C Dock DC300, you can output HDMI signals with higher resolutions. For example, the ASUS USB3.0 HZ-3B Docking Station supports a resolution of up to 3840 x 2160 pixels (4K UHD) via the HDMI port.
- The ASUS Triple Display USB-C Dock DC300 also supports higher resolutions via HDMI, however the specific details are not explicitly stated in the sources, but it is likely that it supports similar or higher resolutions as the HZ-3B Docking Station.

Overall, an HDMI signal with a maximum resolution of up to 3840 x 2160 pixels (4K UHD) can be output via a docking station or a corresponding adapter.
