What this cable does

This ALSEYE USB C cable carries video, data and power over a 30FT length. It supports single-monitor 4K@60Hz or 2K up to 165Hz and dual-monitor 2K@60Hz. The cable works with devices that have a USB-C port supporting DP Alt mode, including laptops, tablets, phones and portable monitors. It is built for users who need a long reach without losing display quality.

Speed that decides fit

Data runs at up to 40Gbps under the USB4.0 standard and is also compatible with 20Gbps USB4 devices. The cable carries USB2.0 data for the Gen2x2 connection. If your host and peripheral both support 40Gbps you get the full bandwidth; otherwise the link negotiates down to the highest shared speed.

Heat noise and power

The cable delivers up to 240W of USB Power Delivery charging, well above the older 100W ceiling, so even large laptops can charge at full speed while the display is active. Passive copper construction means no fan noise and no external power adapter. In normal use the cable runs warm but not hot, and the connectors stay cool during sustained 240W charging and 40Gbps transfers.

Questions about this item

What does the 4K@60Hz rating mean when I plug this cable into my laptop?

It delivers a single external display at 4K resolution and 60 Hz refresh, or 2K at up to 240 Hz, provided the host USB-C port supports DisplayPort Alt Mode.

Which USB standard limits the 40 Gbps data rate and what does it cap in practice?

USB4 Gen 3×2 caps at 40 Gbps; the cable falls back to 20 Gbps on USB4 Gen 2×2 or USB 3.2 Gen 2×2 hosts.

How long is the cable and will it reach my monitor across the room?

The cable is 30 ft long, giving plenty of reach for desk-to-wall or across-room setups without an active extender.
