A:AnswerThank you for reaching out to us. We appreciate your interest in our product. The Insignia™ 24" Class F20 Series LED HD Smart Fire TV does not natively support Miracast or WiDi without a dongle. However, if you’re looking to cast content from your mobile device or laptop, you can use an external Miracast adapter or a compatible streaming device like a Fire TV Stick. These devices allow wireless screen mirroring and streaming, enhancing your viewing experience

A:AnswerFrom what I have learned is that if your tvs are linked to your Amazon account and you watch something on an app you don’t own it will automatically set you up, even if you don’t want to be. You have to go into your settings on Amazon to deactivate whatever tv your not wanting to be linked to Amazon.
A:AnswerI have this TV and use it as both a monitor and TV. The remote allows you to access inputs through the Fire TV settings. It has HDMI inputs.
