I bought this to connect my older Mac Mini to an HDMI input of my AV system. The packaging, when it arrived, implied it was for the opposite: Connecting the more recent HDMI output of a Mac to the DVI input of a monitor. I had a slight panic, but then thought about HDMI and DVI... very similar digitally. Took a chance that the cable was nothing but a connector change and a re-routing of wires, no active nothing. That turned out to be correct -- works just fine in my application. Initially I have it plugged into the front HDMI input, where it looks awful, the white cable into my black AV gear, but oh well. I'll get it moved around back and no one will know.
Four stars because the AV end and cable are white. AV gear has been almost entirely black for years. White is just dumb for this application.
Bought this cable to connect from my Caldigit Thunderbolt Station to a non-apple 27" QHD display. Using an HDMI cable from the Thunderbolt Station works, but the display is most accurately calibrated when hooked up through the DVI port for some reason so I wanted to use this. It will not support 2560x1440 resolution. As soon as I changed it from 1920x1080 to the max 2560x1440 that the display supports it just goes black. It works just fine for any other "normal" purposes and seems like a decent cable so 3 stars for that. I don't have another use for it so back to the store it goes.
