Review on 6ft CableCreation Active DP to HDMI Cable (DP1.2) - 4K x 2K & 3D Audio/Video, Eyefinity Multi-Screen Support, 1.8M, White by Gene Taylor

I fixed the connection between my computer and home theater system and needed to use displayport from my computer to a Yamaha receiver. I've only used it for 1080p videos, not 4k, and everything worked fine once I plugged it in. Audio from DisplayPort to HDMI went through with no issues (which was one of my issues since it's not an active cable). The cable seems to be of decent quality, be careful and remember that DisplayPort has a button that you have to press to disconnect it from your device or you could damage the cable by unplugging it without the disconnect.
