To connect your tablet to your TV using a USB cable, you need to follow these steps:

1. Plug the USB cable into your Android tablet.
2. Plug the other end of the USB cable into your TV’s USB port.
3. Turn on your TV and make sure it's set to the correct input, where you'll find your Android tablet connected via USB cable.
4. Select the option that identifies a media device connected to the tablet. Once the tab opens, select Media device or MTP for using the TV to view images and files.
5. Alternatively, you can choose hard drive mode /picture mode (also appears as Transfer files/Transfer photos) on your tablet, and your TV will access your tablet like a flash drive.
