I bought this to replace the miniDVI to DVI cable that came with my Dell external monitor which I've had lots of trouble with connecting to my mac. My screen used to black out and flicker all the time and all that's gone with this cable. I think next time I would go for the 6ft cable since i underestimated how much length i need. 3ft is barely enough even though my laptop and screen are right next to each other. Thank you monoprice for offering good quality cables for an affordable price.
I'm currently using this cable to connect my Intel NUCs, Microsoft Surface, and Macbook Pro to a few different monitors (1080p and 2160p) with Mini-DP inputs and it works exactly as you'd expect. Audio over the cable works great as well.
I have not tried 3d, 4K30, or 4K60 with this cable, nor Ethernet.
PROS: Small, easily fits into my backpack or leather laptop bag. Affordable Audio works fine
