Adding to that, something that tripped me up at first was making sure both devices were actually on the exact same Wi-Fi network. It’s not enough to just have them both online—they need to be connected to the same router signal, especially if you’ve got both 2.4GHz and 5GHz bands running at home. Another thing to check is whether your TV has any kind of screen sharing or casting option in its settings menu. Some models hide that feature under different names, so it might take a bit of digging.
