Bests & Worsts Reviews from Amazon

Long story short, this is a cable. It appears to be well-made and it works, which are all one can ask of a cable, hence the five stars. For purposes of context, I used this cable to replace the combination of an HDMI cable, and a DisplayPort to HDMI dongle, to connect the DisplayPort video output of my computer to the HDMI input of my LED monitor. I'd been having intermittent problems with the monitor blanking out or losing sync, as well as startup delays during which Windows seemed to be looking for something, both of which seemed to be related to the dongle; so I decided to try this cable instead. It seems to have solved both problems quite nicely. Yay! While reading through the reviews, however, I noticed that some people said this cable didn't fit, didn't work, or reduced the video resolution. I believe most of those folks simply bought the wrong cable. Let me try to simplify things a bit. 1. This cable is designed to connect a full-sized DisplayPort output (for example, on a computer) to a full-sized HDMI input (for example, on a monitor, television, or projector). If that is not what you are trying to do, then this is the wrong cable for you. 2. The source (for example, a computer) must be DisplayPort, and the destination (for example, a monitor) must be HDMI. It will NOT work in the opposite direction. In geekspeak, this is a unidirectional cable, not a bidirectional one. 3. If you're running your display at 4K/UHD (3840 x 2160), then this cable is NOT what you need. 4K requires an HDMI 1.4 cable. This cable is only rated to work at resolutions up to FHD (1920x1080). Finally, please note that you do NOT need a DisplayPort to HDMI dongle if you use this cable. This cable replaces both the dongle and the cable. So if you're currently using a dongle / cable combination, remove them both before installing this cable. Richard
