Which is the digital display interface commonly used for video and power delivery on many devices?

• A. DisplayPort
• B. HDMI
• C. VGA
• D. USB-C

Answer: (D)

USB-C stands out because it combines video capability with power delivery in one compact connector. It can carry video signals through display protocols like DisplayPort Alt Mode or HDMI Alt Mode, so a single USB-C cable can connect a laptop to a monitor. It also supports USB Power Delivery, which can supply substantial charging power over the same cable, letting the device charge while displaying video or connected to peripherals. This versatility is why USB-C is commonly used for both video output and power delivery on modern devices. By contrast, DisplayPort and HDMI focus on digital video (and audio) data and don’t typically provide power over the same cable in everyday use. VGA is an older analog interface and doesn’t support digital video or power delivery.
