Secondly, connect the power adapter to the casting device and then connect it to the display device (e.g., TV, projector). Turn on the display device to ensure the casting device is working properly. Thirdly, connect the computer to the casting device using the appropriate cable type. If using an HDMI cable, insert one end into the HDMI port of the casting device and the other end into the HDMI port of the computer. If using a USB cable, insert it into the USB port of the casting device and the computer's USB port. After that, open the "Control Panel" on your computer desktop and select the "Display" or "Screen Resolution" option. In the multi-display settings, choose the appropriate option such as "Duplicate these displays" or "Extend these displays" depending on your needs. Ensure that the settings of the casting device match those of the computer. Finally, pay attention to stability during the connection process to avoid any interruptions or lagging during transmission. Adjust the resolution and display mode of the casting device as needed to achieve the best display effect. Regularly check for firmware updates for your casting device and upgrade if there is a new version available. If you encounter any connection issues, check for problems with device connectivity, driver installation, network settings, etc.
