What type of port does a standard monitor connect to on a computer?

A standard monitor typically connects to a computer using ports designed specifically for video output, which include HDMI, DisplayPort, and VGA. These ports are intended to carry video signals from the computer's graphics card to the monitor.

HDMI (High-Definition Multimedia Interface) is widely used in modern devices as it can transmit both audio and video signals, making it a popular choice for high-definition displays. DisplayPort also supports high-resolution video and audio and is commonly found on newer monitors and graphics cards. VGA (Video Graphics Array), while older and less commonly used with modern devices, is still relevant for many legacy monitors and setups.

The other types of ports listed serve very different purposes. USB ports are primarily used for data transfer and connecting peripherals like keyboards, mice, and external drives. Ethernet ports are utilized for networking connections to local area networks (LAN) or the internet. SATA (Serial ATA) is a standard used for connecting storage devices like hard drives and SSDs to the motherboard, and it does not have any role in transmitting video signals.

Overall, the choice of HDMI, DisplayPort, or VGA is the correct answer because these ports are specifically designed for connecting monitors and facilitating video output from the computer.
