## Long description

The Renkforce RF-3778672 USB-C to USB4 adapter enables connection between USB-C hosts and USB4 devices while supporting up to 8K UHD video output.

Advantages
The adapter delivers USB4 compatibility together with 8K UHD video support, allowing a single connection to carry both high-resolution video and high-speed data. The 90° USB-C connector minimizes protrusion from the device and reduces risk of accidental cable bending, making it suitable for cramped workstations and wall-mounted displays.

How to use
Insert the 90° USB-C connector into the host device's USB-C port, ensuring the connector is oriented correctly to avoid strain. Connect the USB4 device or cable to the adapter’s USB4-compatible port. The adapter operates passively as a link between host and device; if the connected devices support 8K video and the appropriate cables are used, the display will negotiate the highest supported resolution. No additional drivers are typically required; check device settings to select desired display resolution and data modes.
Usage recommendations
For reliable 8K video and full USB4 bandwidth, use high-quality USB-C/USB4 cables rated for the required data and video performance, and ensure connected devices and operating system drivers support USB4 and the target resolution.
