Where HDMI has two curved notches, DisplayPort only has one, straight notch, as well as a slightly larger connector. If you want to use this over HDMI, you should look elsewhere. However, if your computer has a DisplayPort output, this willgive you much better results than an HDMI adapter.
HDMI to VGA Kit http://www.monoprice.com/product?p_id=11566 IMPORTANT! This adapter does NOT support HDCP, so this will not work in a home theater system and will not support playback of HDCP protected DVDs and Blu-ray Discs™ from your computer.
Didn't expect much, but was very pleasantly surprised.
I've heard many bad things about these active adapters, so I wasn't expecting much when the item first arrived, other than the general ability to display on my monitor. I wanted to see how bad it was, so I took two monitors, identical model, identical settings, and both DVI and VGA inputs, and tested it. I tested several configurations, including active adapter vs native vga/passive adapter and active adapter vs native DVI, and the results I found were very pleasantly surprising. Not only did it outpace the passive VGA adapter in the lagom.nl/lcd-test latency timer photo comparison, but it also outpaced DVI, to my jaw-dropped levels of surprise. I will buy another one if the need arises and am glad that my favorite monitor of seven years can last me for another year or so of gaming, with my RX 480.
