USB-C is the best display input for most people. It works by bundling DisplayPort into USB-C, so offers all the same features as DisplayPort. Yet it retains the features of USB-C including optional support for Power Delivery to charge external devices. This is why we recommend a USB-C monitor for most people. DisplayPort is generally second-best. It supports higher resolutions and refresh rates than HDMI. This input is particularly common on desktop computers.  HDMI comes in third due to lower resolution and refresh rate support. This is improved by HDMI 2.1, but this feature remains hard to find and often adds to a monitor’s price. All three of the options above handle 1080p at 60Hz, which is the most common resolution and refresh rate available today. It’s also important to buy a monitor that has an input compatible with your PC.
