How to use

Connect the adapter’s USB-C plug to a host device that supports DisplayPort Alt Mode. Attach up to two HDMI cables from the adapter’s HDMI ports to the HDMI inputs on external monitors or TVs. Power on the displays and configure display settings in the host operating system to choose between extended or mirrored modes and to set resolution and refresh rate preferences. If the host device does not detect the displays, verify that the USB-C port supports video output and that the HDMI cables and monitors support the selected resolution.

Usage recommendations

For reliable 4K 60Hz performance, use high-quality HDMI cables rated for 4K@60Hz and ensure the host device’s USB-C port supports DisplayPort Alt Mode and sufficient bandwidth. When using high resolutions across both displays, confirm the host device’s GPU and USB-C controller can drive dual 4K outputs; otherwise, consider using lower resolutions or a single external display for optimal performance.
