There is nothing more frustrating than trying to work your way through a jumble of cords and wires around your computer or TV setup. If you dedicate a little extra time to organizing your cables and cords when you setup a device, you will thank yourself later when you find yourself under your desk trying to plug in a new mouse or printer.
There are a few cheap and simple solutions for wire management, ranging from color-coded Velcro and zip ties to custom labels. You can also make labels for your wires with things you have lying around the house, such as an empty milk carton. Start by rinsing out the milk jug and cut out any flat parts. Cut the flat pieces into one-inch squares, and clip the corners at an angle to eliminate sharp edges. Punch a hole about one-eighth of an inch from the edge of the square, and then cut a slit from the edge of the square to the hole you just punched.
Using a fine-point Sharpie, annotate the label accordingly and slip it onto the correct cord.
Taking a moment of your time to organize your cords can really save you a lot of frustration in the future. Best of luck getting your cables labeled and managed!
