Review on Mini DisplayPort HDMI Adapter Thunderbolt by Maurice Stavros

In a system where the direct displayport output was working fine with normal mini DP to DP cables, 4K/60Hz with 2 monitors, same computer, same graphics card and the same monitors (listed for HDMI 2.0 input) at 30Hz using two "red" adapters and one of half a dozen HDMI 2.0 cables, including the one that came with the monitors. Needless to say I am disappointed. Two stars because it might work for others. mine are going back.
