SS stands for "Super Speed" and typically refers to a type of USB cable that supports USB 3.0 or newer standards. Here are some key points about SS cables:

• SS cables are designed for fast data transfer speeds, higher than USB 2.0 cables. USB 3.0 can transfer data up to 5 Gbps while newer standards like USB 3.1 Gen 2 can go up to 10 Gbps.

• They have additional pins and wiring compared to standard USB cables to enable the faster bus speed signaling. Visually they often have blue connectors instead of white or black.

• SS cables are fully backward compatible with older USB ports and cables. For example, you can plug a USB 3.0 SS cable into a USB 2.0 port, it will just fall back to the slower speed.

So in summary, SS cables are a type of high-speed USB cable used to connect devices like external hard drives, docks, and sometimes monitors to a computer. They aren't designed specifically for monitors and don't carry video signals - you'd still use HDMI or DisplayPort for the video connection itself. The SS cable would be used alongside those to enable higher-speed data transfers if supported.

SS stands for SuperSpeed, which is the USB 3.0 standard. For monitors, these cables can carry video, data, and power simultaneously. Common types are USB-C to USB-C or USB-C to DisplayPort cables, often used with modern laptops and monitors.
