Hey amarmistry, glad to hear you got your problems resolved. But for the future, with a run that long between the source unit and your display, even with a booster you are pushihng the capabilities of an HDMI. When running that long, i'd recommend running cat-5s with hdmi baluns on the end. The cat-5 will handle the high data transfer over that length much better than a long hdmi would. just food for thought.
