Review on Monoprice 115888 Mini DisplayPort to DisplayPort Cable - 4K Capable, 1.5 Feet, 3D Video Support by Justin Larjin

Of the seven cables I purchased, this was the only mini DP-DP cable that could actually transmit 240Hz without flickering. Please do yourself a favor and don't waste your money trying to save $2 on other cables. I'm a stingy person, so spending $10 on a cable hurt me, but this was one of those moments where you really get what you explore. Monoprice has the best guarantee and guarantees. Your QC is quite large. You bought an expensive AF monitor, don't burn it with a cheap cable.
