Which of the following cable types would work best for connecting a laptop to an LED TV for video and audio transmission?

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

Answer: (C)

The best choice for connecting a laptop to an LED TV for video and audio transmission is HDMI. This is because HDMI (High-Definition Multimedia Interface) supports both high-definition video and multi-channel audio through a single cable, making it very efficient for this type of connection. HDMI is widely used in consumer electronics, including laptops and televisions, and offers high-quality signals that are well-suited for modern display technologies. In contrast, VGA (Video Graphics Array) supports only video signals and lacks the ability to transmit audio. DVI (Digital Visual Interface) can transmit high-quality video but also does not support audio transmission, which means you would need a separate audio cable to achieve sound. While USB-C can transmit both video and audio signals, its compatibility is dependent on the specific devices involved. Not all laptops and TVs support video input through USB-C, making HDMI the most universally compatible option for connecting these devices.
