Here is the component list of the UGREEN USB-C to DisplayPort 8K Cable for your convenience.

It features a nylon-like braided jacket and aluminum alloy connector housings, offering both durability and a refined look. Available in four lengths—1m, 1.5m, 2m, and 3m—to suit various usage scenarios. The cable supports a total bandwidth of 32.4Gbps and is compatible with technologies such as G-Sync, FreeSync, FEC, and DSC. It also supports graphics cards from AMD and NVIDIA, 8K resolution, and Dolby Atmos surround sound for an immersive gaming and cinematic experience.

After taking it apart, we found that the USB-C connector features internal injection molding and a reinforced steel sleeve for added durability, with gold-plated pins for improved conductivity. The DP connector includes shielding covers to reduce interference. On the PCB, there is a VIA Labs VL103-Q3 chip along with a Puya memory chip.

Inside the cable, there are multiple shielding layers, including a braided mesh and aluminum foil. This multi-layer shielding effectively minimizes signal interference and loss, resulting in more stable signal transmission. It significantly reduces the likelihood of issues such as lag, screen flickering, or blackouts. Overall, the build quality is solid and reliable.
