Good morning,
If your tablet has a usb-c port, you can hook it directly to your tv using a usb-c to hdmi cable. I use that setup with my chromebook and Ipad, works great also works with some cell phones that have usb-c as well. You can find them on amazon or even at everyones favorite store walmart lol. Have a blessed day..
Chris
Unfortunately, Amazon did away with the ability to mirror your tablet screen to your TV, so using a USB C to HDMI cable does not work with my Fire HD8+ tablet.
I wound up having to use a Chromecast on the TV, Setting up a mobile hotspot on my phone, then using the Google Home app on my tablet.
What a pain in the neck...
