Tried to use this item, and one screen was fuzzy. Yes, I tested it with different cables and monitors and it was definitely because of the switch. Exchanged the item for another, which had a similar problem, tinting the entire display screen blue. Not wanting to waste my time sending it back, I played with it for a while to make sure it was a defective switch. It was. Buyer beware.
