If you've ever used the trackpad on a PC laptop connected to an external monitor and noticed how many times you have to swipe your finger across the pad to get the mouse cursor from one screen to the other, the end result can be quite frustrating and tiresome. Of course, the same thing can easily happen if you hook up an external display to your MacBook or iMac, although it usually is not as obvious thanks to the larger surface area that Apple has designed into recent trackpads. Luckily, this can be easily corrected on any Mac in just a few simple clicks.
Before we dive into the settings, though, let's talk about what is causing this to happen in the first place. Although we often take it for granted, one of the most astonishing aspects of using a mouse with a computer is the fact that you only have to move your hand by a couple of inches, while the pointer on the screen moves from one end of the screen to the other -- even if the screen is over 20" wide. This feat is accomplished by a simple mathematical conversion being done in the background that measures the distance the mouse (or your finger, if using a trackpad) moves and multiplies that by a specific factor to determine how far -- and in what direction -- to move the cursor on the screen.
Read on to find out how to give your mouse (or trackpad) a speed boost.
