And the winner is...
The overall winner among today’s display standards for the PC is clear. It’s USB- C. It’s the most flexible, feature-rich, and capable of the three main options. The ability to plug a laptop into a monitor with a single cable, and drive it at very high resolutions and refresh rates, at the same time as charging the laptop and enabling the connection of USB devices is very, very cool. USB- C is also perfect for next-gen VR gaming with a single cable. Even on the desktop, the simplicity implied by USB- C is a significant boon. Of course, remember that USB-C as a display connector is only as good as the DisplayPort interface underneath. Also bear in mind that this subject is something of a moving target. HDMI 2.1 has been announced, and should soon begin to appear in devices. It has the edge on DisplayPort 1.4, and thus USB- C, for outright bandwidth, if not overall features, so may be the better option for some edge cases with really high spec displays. Meanwhile, the upgrade path for DisplayPort, and its support for future cutting-edge PC monitors, is a little uncertain.
