- 1x Cable Matters active HDMI-to-DisplayPort converter

DisplayPort Cable Not Included. You will need a separate DisplayPort cable from the converter\'s female DisplayPort output to the monitor\'s DisplayPort input. Please confirm your equipment has the correct ports before ordering. Easy Setup
- Connect USB-A power. Plug the attached USB-A connector into a computer USB port or suitable USB power supply first (recommended).
- Connect HDMI. Insert the adapter\'s HDMI male plug into the HDMI output on your laptop or desktop.
- Connect the monitor. Use your separately purchased DisplayPort cable between the adapter\'s female DP output and the monitor\'s DP input.
- Select the right input. Choose DisplayPort on the monitor and configure your computer for duplicate/mirror or extended display.
Troubleshooting: If there is no signal, make sure USB power is connected, select the correct DP monitor input, and test at 1080p/60Hz. Avoid KVM switches, docks, and extra converters during initial troubleshooting. Buyer\'s Quick FAQ
