We recommended the Greenlee Data Shark HDMI Cable Tester.
The Greenlee DataShark HDMI cable tester can test for proper continuity before installation. Also a great diagnostic tool for checking cables already installed. The 1 piece design splits into 2 pieces a transmitter and receiver. The 9 LED readout is easy and very fast to read.
The contractor checked it out and for the price it was well worth putting another tester into his collection.
