4K USB-C to HDMI Adapter

The C2G54459 adapter connects a USB-C source to an HDMI display at up to 3840 x 2160 resolution. It serves laptop and desktop users who need an extra video output without opening the case. The 7.9 inch cable keeps the link short and tidy for desk setups. Plug-and-play operation suits both home office and travel use.

Single-cable video expansion

The male USB-C plug inserts directly into the host port while the female HDMI socket accepts a standard display cable. No external power brick is required, so the adapter draws what it needs from the host bus. This frees up a docking station port or avoids a bulky multi-port hub when only one extra screen is needed. The compact form factor leaves adjacent ports unobstructed.

Passive thermal profile

With no active cooling, the adapter runs silently during typical office workloads. Power draw stays within the USB-C port’s standard delivery capability, adding negligible load to the host system. The short 7.9 inch length minimises signal loss and helps maintain stable 4K output. Heat remains low enough that the black plastic housing stays comfortable to touch.

Questions about this item

Will the 3840x2160 output hold steady during long sessions or hit a thermal throttle?

The adapter is a passive 7.9-inch dongle with no active cooling; sustained 4K output relies on the host port's power and thermal limits.

Does the adapter generate noticeable heat or fan noise when driving a 4K display all day?

It has no fan and draws power only from the USB-C port, so heat stays low and operation is silent.

What host port must my laptop already have for this C2G54459 to work?

A USB-C port that supports DisplayPort Alternate Mode video output.
