If you plan on connecting external displays to your laptop, you need to know which alternate mode your device supports and buy a display or an adapter that supports that mode. Your laptop has DisplayPort if there's a D-Shaped icon next to your USB-C port, but it also might have it and not have that icon. There's also DisplayPort, which is bundled with ThunderBolt 3 but also offered independently on some devices. HDMI and MHL, for example, both allow certain kinds of displays to be connected. But only devices built to be compatible with Thunderbolt 3 can get those speeds, and even then, only if you have a Thunderbolt 3 compatible cable. Thunderbolt 3, for example, is a collaboration between Intel and Apple that offers transfer speeds of 40 gbps-four times faster than the USB 3.1 standard-and support for two 4K displays connected to a single port. The complexity here is introduced by alternative modes, which use the USB-C form factor to offer additional features. So, for example, if you plug a USB-A device (like a cell phone) into a USB-C port using one of these cables, the phone may draw too much power, frying your phone, USB-C port, or even computer. (USB-A, if you didn't know, is the traditional USB plug we've all been using for years.) But USB-C devices (and cables) support faster charging than USB-A. The problem is specific to cables with the older USB-A connector on one end and the new USB-C connector on another. That's not the case with USB-C, and ignoring this could cost you dearly. People mostly didn't need to think about which cables to buy. Sure, if you plugged a USB 1 cable into a USB 2 port, it might not work-or at least, work well-but that was the extent of it. In previous generations of USB, a cable was pretty much a cable. ![]() ![]() This is the most pressing thing new USB-C users need to learn about. If you're new to the USB-C port, we'll share a few things you should look out for. The problem is not every USB-C port is the same, and not every USB-C cable you can buy works the same way. You can also find USB-C on many Windows laptops and an ever-growing number of accessories. ![]() Apple's MacBooks, iPads, and the iPhone (starting with the iPhone 15 series) also use USB-C. The vast majority of Android phones have been using USB-C for years.
