## Long description

Compact QOLTEC adapter that converts a USB‑C port to a USB‑A connector and an HDMI output supporting up to 4K at 30 Hz. The adapter is housed in an aluminium casing that offers a slim profile and improved heat dissipation. It provides simple connectivity for peripherals and external displays from laptops, tablets or phones with USB‑C, enabling presentations, multimedia playback and connection of USB devices without additional hubs.
Advantages
The aluminium housing ensures a durable, lightweight design and helps dissipate heat during extended use. The adapter combines a USB‑A port and an HDMI 4K 30Hz output in a single compact unit, reducing the number of separate adapters or cables required. Plug-and-play operation requires no driver installation on most modern systems, and the USB‑A connector supports standard USB peripherals such as keyboards, mice and flash drives.

 Connecting an external monitor or projector for presentations or video playback
 Attaching USB‑A peripherals to laptops, tablets or phones with USB‑C
 Home office setups that require an additional display and peripheral connection

How to use
Insert the USB‑C connector of the adapter into the USB‑C port of your laptop, tablet or phone. Connect an HDMI cable from the adapter’s HDMI output to an external monitor or projector, and plug USB‑A peripherals into the USB‑A port. On most systems the external display will be detected automatically; use your operating system display settings to select mirror, extend or primary display mode. If a device requires USB host mode or alternate display mode, ensure that the source device supports those functions.
Usage recommendations
For stable video output at 4K 30Hz, use a high‑quality HDMI cable and connect to a display that supports the specified resolution and refresh rate. Avoid forcing the adapter into tightly packed ports and disconnect gently to prolong connector life. If the host device does not detect the display, check USB‑C alternate mode support and update the device firmware or drivers where applicable.
