Show answer and explanation
Correct answers: A, B, C
Explanation
To connect the laptop to the monitor, you must consider the supported ports on both devices and the necessary cables or adapters. HDMI is a straightforward option since both devices support it. USB-C to VGA and USB-C to DisplayPort are also valid solutions, assuming the USB-C port on the laptop supports the required functionality. However, a VGA to HDMI converter cable is not valid without additional hardware for signal conversion.
- A. Correct.
Correct. The laptop and monitor both support HDMI, so an HDMI cable is a valid option for direct connection.
- B. Correct.
Correct. A USB-C to VGA adapter converts the USB-C output from the laptop to VGA, which the monitor supports via its VGA port.
- C. Correct.
Correct. A USB-C to DisplayPort cable can connect the laptop's USB-C port to the monitor's DisplayPort input, as long as the USB-C port on the laptop supports DisplayPort Alt Mode.
- D. Incorrect.
Incorrect. VGA to HDMI converter cables typically require additional hardware for signal conversion, and it is not specified that the user has such a device.
