So, what makes the Cable Matters HDMI to DisplayPort adapter stand out? For one, the USB power cable is 3-feet long and gives you enough flexibility to route it as per your preference. Do not have the USB port next to the HDMI port free? Sure, the long USB cable will take care of the issue. Alternatively, you also get the option of connecting it to a dedicated power source. Here too, the refresh rate reaches a maximum of 30Hz while running content at 4K resolution. Thankfully, it supports 2K content up to 60Hz. In most cases, that power source is provided through USB, which means a USB cable is included with the adapter. You might find alternatives to USB power connections, like DC power connections. But USB power is usually the simplest and most reliable way to get the job done because it doesn’t require you to get another adapter or power-box involved. Format Versions If you’re willing to drop down to 1080p, you’ll find support doubles to 60Hz. You can also get 60Hz while running at 1440p, at least if your video card happens to support it. Unlike the popularity and the easy availability of DisplayPort to HDMI connectors, HDMI to DisplayPort Adapters are a tad tough to source. At the same time, these are uni-directional and work only for this kind of setup. But the good news is that most high-end monitor setup doesn’t need the extra power source.

These adapters might be handy in a pinch if you absolutely need to drive a DisplayPort device and all you have is an HDMI output--maybe if you're using a laptop to deliver some presentation on a bigger screen--but anybody expecting them to be a perfect long-term substitute for a native HDMI-to-HDMI connection will be disappointed. The Cable Matters HDMI to DisplayPort Adapter uses a really clever design. For the DisplayPort and HDMI portion of the device, it only stretches about six inches, which is all most people really need. But it stretches three feet for the power connection, which makes it far more versatile than adapters like the StarTech HDMI to DisplayPort adapter.

The USB power is made with a Type-A connector. The size of the USB-A connection head is quite small, measuring about 1.8” in length. And the size of the core adapter is equally quite small, measuring 1.69 x 0.71 x 0.31 inches. It’s worth noting you’ll find gold plated connection terminals, except for the USB-A connection, which is only running power so wouldn’t really benefit from the added effort. Most monitors include more than one display port, with some even having separate ports such as HDMI, DisplayPort, or VGA. However, this case does not apply to all monitors, so you may be in a situation where you need to connect an HDMI laptop to a monitor with only DisplayPorts.
