Make a monitor with only 1 cable leaving it
Currently, the monitor on my desk has several cables running to/from it. At the least would be 1 input cable and a power cable, but as you take advantage of the multitude of inputs, you get a mess. The plan would be to develop a system where only 1 cable leaves the monitor (carrying all the video, power, data, etc) to a small connection box that one could put under the desk or on the floor. This way, all the inputs, power and data could be connected there and only send 1 cable to the top of the desk. This reduces clutter and leaves some flexibility in placement of the monitor. I have it on an articulating arm and would love to have to only send 1 cable up and make one connection.
The challange will be to not have a huge cable that is impossible to bend.
DisplayPort offers video, audio, and soon USB carried over the same cable.
