What the cable connects
The SMUGDESK USB C to HDMI 2.1 Cable links a USB-C or Thunderbolt 3/4 source to an HDMI display. It carries video at up to 8K resolution and supports 48Gbps bandwidth for high-fidelity signal transmission. The ten-foot braided cord is unidirectional and does not carry power or charging current.
Who this suits
Creators and professionals who need 8K@30Hz or 4K@120Hz output from a laptop, tablet or phone with DP Alt Mode will find the bandwidth and HDR support fit for colour-critical work. Gamers targeting 2K@144Hz or 240Hz refresh rates also benefit from the high throughput. Buyers who require USB-PD charging through the same connection, or need HDMI-to-USB-C input direction, must choose a different adapter.
Bandwidth and resolution ceiling
The cable delivers 48Gbps bandwidth enabling 8K@30Hz, 4K@120Hz and 2K@240Hz modes with Dynamic HDR, DSC 1.2 and HDCP 2.3 compliance. MacBook hosts are limited to 4K@60Hz by the host controller, so 8K output is only possible on devices that expose full HDMI 2.1 capability over USB-C.

Questions about this item
How do I connect the USB-C end to my laptop and what is the common mistake?
Plug the USB-C connector into a port that supports DP Alt Mode or Thunderbolt 3/4; the cable only works from USB-C to HDMI and does not carry power.
What part of this cable is most likely to wear out first?
The braided jacket and gold-plated connectors resist wear; the internal wiring is rated for 48Gbps bandwidth and requires no user maintenance.
At what resolution and refresh rate does the 48Gbps bandwidth limit appear during long sessions?
The cable sustains 8K@30Hz, 4K@120Hz or 2K@240Hz within its 48Gbps bandwidth; higher rates would exceed the HDMI 2.1 limit.
