USB-C to 4K HDMI Adapter

The SIIG USB Type-C to HDMI adapter converts a USB-C port with DisplayPort Alternate Mode into an HDMI output. It supports video up to 3840x2160 at 60Hz and audio up to 7.1 channels with 24-bit 192 kHz sampling. The reversible USB-C male plug connects to the host while the HDMI Type-A female port accepts a standard cable. It is suited for users adding an external display to a compatible laptop or desktop.

Sustained 4K 60Hz Output

The VL100+PS176 chipset delivers up to 6.0Gbps bandwidth to maintain 4K resolution at 60Hz during extended sessions. HDCP 2.2 and 1.4 support ensures protected content plays without interruption. The adapter draws power from the USB-C port and requires no external supply. It is not for users whose USB-C ports lack DisplayPort Alternate Mode or Thunderbolt 3 capability.

Plug-and-Play Installation

Driver-free operation works on systems with a DisplayPort Alternate Mode enabled USB-C or Thunderbolt 3 port. The reversible plug removes orientation guesswork. Common issues arise when the host port supports data only or when the HDMI cable exceeds the adapter's bandwidth limit. The package includes only the adapter; an HDMI cable is required separately.

Questions about this item

Does the 6.0 Gbps bandwidth generate noticeable heat or power draw when the adapter runs all day?

The adapter draws power from the host USB-C port and uses a VL100+PS176 chipset; typical operation at 3840x2160 @60Hz stays within standard USB-C power limits and does not require active cooling.

What must my laptop already have for this adapter to work?

Your device needs a USB-C port that supports DisplayPort Alternate Mode or a Thunderbolt 3 port, plus an HDMI display to connect to the female HDMI output.

Will this adapter work with my older 1080p monitor that only has HDMI 1.4?

Yes, the adapter supports HDCP 1.4 and 2.2 and will downscale 4K signals to 1080p @60Hz over the HDMI 1.4 link.
