There’s some contention over whether daisy-chaining multiple 4K monitors is possible over USB-C, though. You’ll also get all the benefits of DisplayPort 1.4, which is still a highly capable standard. USB-PD means you won’t have to bring a charger with you to plug into a monitor. USB-C is a great choice if your laptop is compatible with it-particularly if you move around the house or workplace a lot. However, it falls slightly short of the 96 W “required” by a 16-inch MacBook Pro (although the machine rarely sucks up that much power). That’s more than enough to charge a MacBook Air or a Dell XPS 13 laptop. For example, the Dell UltraSharp U3219Q offers USB-C connectivity, with 90 W of USB-PD. You’ll need to do your research first to make sure your monitor provides the right power output for your laptop. If your laptop supports USB-PD (and many do), you can charge your laptop and output to a monitor with a single cable. USB-C Alt Mode display output should also provide support for USB Power Delivery (USB-PD). This will likely be included in the technical specifications or on the manufacturer’s website. However, you’ll need to make sure your laptop supports display output over USB-C Alt Mode. One of the main reasons to choose USB-C is ease of use-USB-C ports are on all modern laptops. With display stream compression, it’s theoretically possible to get an 8K signal at 60 frames with 10-bit color, or an uncompressed 4K 8-bit signal at 120Hz. This means all the technical aspects of USB-C DisplayPort over Alt Mode mirror those of regular DisplayPort 1.4. The raw throughput and supported resolutions depend on the DisplayPort standard being used (at this stage, it’s likely 1.4). In essence, this is just DisplayPort via a USB-C plug. The ability to carry a display signal over USB-C relies on a technology called USB-C Alt Mode. RELATED: DisplayPort 2: What's Different, and Why It Matters USB-C: Ideal for Laptop Owners In the future, with the arrival of DisplayPort 2.0, 4K at frame rates of higher than 60 frames in true 10-bit color will be possible, but only on a monitor that supports it. HDMI, on the other hand, has broader applications, including connecting AV receivers, TVs, and other consumer electronic devices.ĭisplayPort offers some good advantages over HDMI 2.0, but they mostly only apply if you want to daisy-chain multiple monitors. This is primarily because DisplayPort is mostly used for computer-to-monitor connections. Unlike HDMI, DisplayPort lacks any kind of Ethernet support. This means most people will still be using the DisplayPort 1.4 standard, which still stacks up favorably when compared to HDMI 2.0. It’s worth noting, though, DisplayPort 2.0 devices aren’t expected to hit the market until late 2020. While HDMI 2.1 caps out at 48 Gbps, the upcoming DisplayPort 2.0 standard can handle a throughput of 80 Gbps. DisplayPort: Better, Faster, StrongerĭisplayPort has long been the PC enthusiast’s choice, and, on paper, it’s not hard to see why. If your monitor only supports HDMI 2.0, DisplayPort could provide a better experience in terms of overall features-especially if you want to daisy-chain more than two displays. If you’re rocking a 4K monitor with HDMI 2.1, you’re unlikely to hit any serious bottlenecks at this stage. These older HDMI 2.0 4K monitors will save you some money, but you’ll also lose out on some features. HDR content is limited to static metadata (the HDR 10 standard) compared to 2.1, which supports dynamic metadata (including HDR10+ and Dolby Vision). For gamers, HDMI 2.0 doesn’t support the FreeSync standard.
