StarTech.com Mini DisplayPort to DisplayPort Adapter Cable 1.2 to 2m - Mini DP to DP cable with HBR2 support M / M - DisplayPort 4k (Accessory)
This cable connects an nVidia GTX680M a B2888UHSU Iiyama screen. This cable fully supports the DisplayPort 1.2 mode, ie 3840 x 2160 60Hz! No image problem, no image jump. Nothing to say, that's good! Thank you.
