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. The StarTech HDMI to DisplayPort Converter is reasonably small and portable, measuring 6.69 x 5.59 x 1.18 inches, and weighing about an ounce and a half. Because the cable only runs about six inches, you need to have everything pretty close for everything in your setup to reach without needing extension cables. In many ways, build quality is the most obvious thing you should consider. But it can also be very easy to overlook. If you plan on using your adapter in a mobile capacity, then you’ll want to pay special attention to the quality of its build. Because for that type of use, you need the adapter to be able to be plugged in and out, over and over. When compared to a lot of similar adapters, Cable Matters delivers what could be called a generally superior quality. Because this isn’t a brand that makes adapters and cables on the side, it’s their main focus as a brand. It’s easy to see that focus in the design of their products. Here you’ll notice gold plated connection terminals on the ends of the adapter, helping to protect the connections from corrosion.

The housing of each adapter is made from sturdy ABS, which is both impact resistant and able to handle heat pretty well. The total adapter weighs about half of an ounce, which is reasonably lightweight, as you might expect. Aesthetically, the only thing to point out is the Cable Matters logo is embedded on the topside of the DisplayPort portion of the adapter. That makes it a little easier to determine which portion of the adapter is which.Once connected properly, this adapter provides active HDMI to DisplayPort conversion. That means you can transmit high definition audio and video from your PC to a DP monitor pretty easily, and expand your workspace to a second monitor. The 4K video resolution support means you’re covered for resolutions up to 3840 x 2160, at least while running at 30Hz. Other Considerations However, keep in mind that HDMI output cannot translate properly to a DisplayPort input if you simply use a passive adapter. It prevents you from using all the functionalities of the monitor, so you need to use an active adapter instead. An active adapter consists of some computing power that actively translates the signals from HDMI to DisplayPort-compatible and vice versa. 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
