To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Works as expected for remote desktop/screen sharing purposes, without the need to keep a display connected to the remote computer. Using this on an Apple Mac Mini its display options are the same as with a connected display, up to 1080P (might be a function of my ~2011 era computer). Screen sharing is as fluid as with a display connected. While the plug's black plastic design not as aesthetically attractive as some of the other equivalents dummy plugs available here, you get a three-pack for about the same price as one of those other ones. I really only needed one and would have preferred that option if available.
