USB graphics adapter QOLTEC 50375, compact black adapter for external display connection
QOLTEC 50375 USB graphics adapter is a compact black adapter that enables connection of an external display to a computer via a USB port. With dimensions of 45 × 45 mm and supplied as a single piece in a polybag, this adapter provides a simple solution for systems that lack a native video output or when an additional monitor is needed. The device performs video output conversion to allow extended desktop, duplicate display, or presentation playback on external screens.
The adapter's compact form factor and lightweight construction make it easy to carry and install without occupying significant space. It offers a straightforward plug-and-play approach for adding an external display through a USB interface, reducing the need to open the system for internal upgrades. The black finish provides a neutral appearance that fits typical office and home setups.
Connect the adapter to an available USB port on the host computer, then attach the external display cable to the adapter's video output connector. If required by the operating system, install any necessary drivers or follow on-screen prompts to enable the new display. Configure display settings through the system display control panel to choose extended, duplicated, or single-display modes. Ensure the external monitor is powered on and set to the correct input source.
For best results, use a stable USB port directly on the computer rather than through an unpowered hub. Verify driver compatibility with your operating system before use and confirm the display input matches the adapter's output type. Keep the adapter in a protected location when not in use to avoid physical damage.
