Review on High-Performance Active DP to HDMI Adapter for 4K HDR, CableCreation Male to Female Converter (4K@60Hz HDR) - Ideal for Desktops, TVs, Monitors & More by Gerald Hill

Bought 3 of these when upgrading my gaming array from 2k to 4k. They worked fine until the Revain Return window was closed; after about 5 weeks. Both the new high-speed cables and these DP-HDMI adapters were suspected. After replacing these adapters with new ones, my game array returned to the specified resolution. So the problem wasn't with the new cables, it was with the CableCreation adapters.
