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.
