This solution is ideal for applications where your DVI monitor needs to be placed further than the average 20 meter DVI cable limitation. Driving a DVI signal over Cat 5 means that you can take advantage of your UTP cable infrastructure already installed for a cost-effective & reliable in-wall installation. This DVI over Cat 5 solution is ideal for applications where you need to place your computer in remote location. This is common in digital signage applications typical in retail stores, houses of worship, classrooms, & boardrooms where you need video presentation in one room but want the computer to be out of sight & in a safe & secure environment.
