Plugable's DisplayPort to HDMI passive adapter (DPM-HDMIF) allows you to connect from a Dual-Mode DisplayPort (DP++) output on your laptop, desktop, or tablet to virtually any HDMI-enabled display. Passive adapters rely on the DisplayPort output of the host system to provide the necessary signaling to support an HDMI display. The adapter supports resolutions up to 4K 30Hz (3840x2160 @ 30Hz). All resolutions below 4K—such as 2560x1440 and 1080p—are supported at 60Hz refresh rate. Are you wondering if your DisplayPort output supports DP++? These ports are often noted with a DP++ symbol next to the port itself. If you may be unsure if your DisplayPort port is DP++ capable, please check with your system manufacturer.
