I want to connect my laptop to the TV to watch movies, but their interfaces don’t match. Is there any audio-video adapter that can solve this problem and ensure high-definition quality?
If your laptop doesn’t have an HDMI port, you can use an HDMI adapter. Several types of HDMI adapters are available, such as HDMI-to-USB-C and HDMI-to-Mini DisplayPort, depending on the ports available on your laptop and TV. For example, if your laptop has a USB-C port and your TV has an HDMI port, you can buy an HDMI-to-USB-C adapter. By the way, don’t forget adjust the display settings on your laptop to ensure the correct resolution and aspect ratio for optimal viewing experience.
