Book excerpt: Reduce cable clutter and maximize peripheral performance Version 2.0, updated December 08, 2023 Frustrated with your peripheral cables? Tangled up in standards and compatibility? Don’t know your Thunderbolt 5 from your USB 3.1 Gen 2? Glenn Fleishman figuratively cuts through the mess of ports, cables, and protocols with Take Control of Untangling Connections. The book answers hundreds of questions and helps you troubleshoot common problems, such as identifying cable capabilities. You’ll learn how to buy the best cable, recognize and research ports, and understand the latest about USB4 2.0 and Thunderbolt 5. You get all the answers on how to connect USB, Thunderbolt, Ethernet, DisplayPort, HDMI, and audio at the fastest, best, or highest-fidelity method available.n We spend our lives plugging stuff into our computers, smartphones, tablets, and other hardware. Why is it so hard to make it all work as we expect? Glenn Fleishman knows the answer to this: standards don’t develop in lock step, and whenever anything is out of sync, we wind up with frustration. He also knows the questions! As a writer about all things Apple for decades, he has used multiple generations of interface and connection standards, and he reads hundreds of questions a months from readers wrestling with their gear. In Take Control of Untangling Connections, Glenn puts power (and video and data and more) back in your hands by helping you cut through cable clutter and confusion and find the right plug for the right jack—and the right cable. Glenn posted an 11-minute video on YouTube about cables and connectors to answer some common questions, and it also serves as a preview of the book: You’ll learn the answers to questions like: • How do I ensure I have the fastest connection between any combination of USB and Thunderbolt standards? • What’s the fastest computer-to-computer connection? • What's new with the latest standards—USB4 2.0 (80 Gbps), Thunderbolt 5, and DisplayPort 2.1? • Why is my USB-C cable handling data only at 480 Mbps? • How can I make sure my 1080p, 4K, 5K, 6K, or 8K display can show its maximum resolution? • Why can’t I connect more displays to my computer? • How do I know how many watts a given port can offer a device I plug into it? • I plugged my laptop (or tablet) into a USB-C port—it’s only charging at a trickle, but the port says it should offer up to 100 W. How can I fix this? • What’s the fastest generally available computer-to-Ethernet connection? • I have an unmarked cable with USB-C on one end and a Type-A connector on the other. How fast can it transmit data? • This cable isn’t marked, but it has USB-C at both ends. What kind of cable is it? • How can I test USB-C and USB Type-A cables to find out what they’re capable of? • What's the latest on USB-C’s march towards mandatory mobile device support? • What sort of adapter, dock, hub, or switch might I need to connect this thing to those things?
