Methods for connecting a laptop to a television include High-Definition Multimedia Interface, Video Graphics Array and media streaming. If both the laptop and TV have the necessary ports, HDMI is typically the simplest method. Plug a HDMI cable into both the laptop and TV. Ensure that the laptop is set to display on a second screen and that the TV is on the correct input. Connecting using VGA is a similar process but may require an additional 3.5mm audio cable.
If the laptop lacks a HDMI port, consider using a USB to HDMI adapter. Some such devices require additional software to display video via a USB port.
To change the display settings on a Windows laptop, go to the Control Panel, select Display, and click on Adjust Resolution. In the Display drop down box, select the TV. If sound does not initially play on the television, on the laptop go to Control Panel, and select Sound. Then find the television in the list of playback devices, select it, and click Set Default.
The process for connecting a laptop to a television using a media streaming device, such as a Roku or Chromecast, depends on the specific device. In general, they are plugged into the TV's HDMI port and can be accessed by laptops and other devices over Wi-Fi.
