Frequently Asked Questions

Will this adapter let me connect my DisplayPort computer to an HDMI TV?

No. This adapter is unidirectional and only converts an HDMI source to a DisplayPort monitor. For a DisplayPort computer feeding an HDMI TV, you need a separate DisplayPort-to-HDMI adapter.

Can I run 4K at 60Hz through this adapter?

No. It supports up to 3840x2160 at 30Hz. For 60Hz you are limited to 2560x1440 or 1920x1080, and Cable Matters states it is not designed for 4K@60Hz, VRR, or high-refresh-rate gaming.

Does it come with a DisplayPort cable?

No. A separate DisplayPort cable is required to connect the adapter to your monitor. A USB power cable is included in the box.

Why would I need to plug in the USB power cable?

Some low-power HDMI sources cannot supply enough power on their own. Connect the included USB cable if you see no signal, flickering, intermittent disconnects, or instability at higher resolutions.

Will it work with my DisplayPort KVM switch?

Cable Matters does not recommend it for DisplayPort KVM switches due to possible compatibility issues. It is intended for direct HDMI-to-DisplayPort connections at office workstations, home desktops, and laptop docking setups.

Key Features

  • Unidirectional HDMI to Display Port Adapter: This unidirectional HDMI to DisplayPort adapter only converts from HDMI source to DisplayPort monitor, such as a laptop or desktop with HDMI output to DisplayPort input on a monitor. It will not work from a DisplayPort computer to an HDMI monitor/TV. A separate DisplayPort cable is required for setup.
  • Extend or Mirror Your Display: Use this active HDMI-to-DisplayPort adapter to add a second monitor, mirror your screen, or extend your desktop workspace. This HDMI to DP adapter works with HDMI-output laptops and desktops, including Dell Inspiron 14 Plus 7440, Inspiron 13 5330, Inspiron 14 5440, Latitude 3550, and HP 14" Laptop AMD.
  • 4K Video Resolution Support: Supports up to 3840x2160@30Hz, 2560x1440@60Hz, and 1920x1080@60Hz, depending on the HDMI source, DisplayPort monitor, cable, and video card used. This HDMI Displayport Adapter is NOT designed for 4K@60Hz, VRR, or high-refresh-rate gaming.
  • Durable & High-Quality Build: Gold-plated connectors and a sturdy housing built for direct HDMI-to-DisplayPort connections. Ideal for office workstations, home desktops, and laptop docking setups, but is NOT recommended for use with DisplayPort KVM switches due to possible compatibility issues.
  • USB Power Cable Included: Some low-power HDMI sources may work without extra power. BUT connecting the included USB power cable is recommended for stable performance. Use USB power if the HDMI output to DisplayPort input shows no signal, flickering, intermittent disconnects, or instability at higher resolutions.
