I have an Atlona AT-HD4-SI40SR HDMI extender over a single UTP solid core cat 6 cable. Sometimes if I have a static electricity buildup and touch my metal treadmill that is in the entertainment room, the picture will black out, then come back a second later. Also, other times it will black out without a spark.
Does this sound like an EMI issue or more of a power line issue? I hope there is a remedy short of buying shielded cable (which really isn't a great option due to hassle in re-wiring, cost, etc.) Thanks for any help
