3. DP 1.2 to HDMI 2.0 "active" adapters are coming late 2015

For those who need to squeeze every bit of quality/performance, there will be "active" adapters for DP 1.2 ->HDMI 2.0 conversion by the end of this year, supporting up to 14.4 Gbit/s bandwidth with 600 MHz clock. DisplayPort 1.2 has 17.28 GBit/s of bandwidth (HBR2), more than enough for HDMI 2.0.
