Which of the following video connections provides the highest resolution?

USB (Universal Serial Bus) is primarily a data interface, though some versions can support video (e.g., USB-C with DisplayPort Alternate Mode), it's not primarily a dedicated video connection in the context of these options.

S-video (Separate Video) is an analog video signal that separates brightness and color information, offering better quality than composite video but significantly lower resolution than digital standards like HDMI.

HDMI (High-Definition Multimedia Interface) is a digital interface capable of transmitting uncompressed video and compressed/uncompressed digital audio. It supports resolutions far beyond VGA and S-video, including 4K and 8K, and is generally considered the highest resolution option among those listed.

VGA (Video Graphics Array) is an older analog video standard that transmits RGB signals and provides lower resolutions compared to modern digital connections like HDMI.
