Lindy Mini DisplayPort 1.2 to HDMI 2.0 Active Converter (18G)

Mini DisplayPort source. 4K HDMI display. You need the full 60Hz at 4096×2160, not a scaled-down 30Hz compromise. This Lindy active converter runs the full 18G bandwidth and gets you there. It also plays nice with multi-monitor setups — AMD Eyefinity, NVIDIA Surround, Intel Collage all supported. If your Mac or ultrabook has Mini DP and your new panel is HDMI 4K, this is the one that actually keeps the signal clean at full refresh
