That way, you can make sure they won’t be competing for the same few millimeters of space. add up the estimated length for each one you plan to connect. Since standard cables come in fixed increments like 3, 6, or 10 feet and a cable that is exactly the estimated length leaves zero slack for adjustment, you should always round up to the next standard cable length rather than purchasing the exact number displayed. When operating a monitor arm, this is especially important because the arm must swing and extend without pulling on a cable that was precisely cut to its resting position.
