What is Redmere? Redmere is a very intelligent company out of Ireland that developed a clever little HDMI chip that improves bandwidth, extends cable capabilities, and compensates for data loss. This translates to thinner HDMI cables that can go longer distances without any loss to quality.
Need a flexible, super thin, high performance High Speed HDMI® Cable? A High Speed HDMI® Cable with RedMere® technology delivers excellent signal integrity over long distances using the slimmest cables available. This cable is easier to route and easier to hide than traditional thicker, bulkier HDMI cables and still fully supports 3D, 4K, and HD 1080p applications. RedMere® technology is directional so one end must be connected to the source device and the other end connected to the sink / display device. Connecting the cable backwards will not damage anything but it won't work.
