Are you sure the TCL Roku TV and the mirroring device are on the same Wi-Fi network? It’s a common snag, but there’s more you should check out.
First off, be aware of your devices’ compatibility. If you’re using an iOS device, native support might be lacking unless you grab a third-party app. For instance, grab DoCast from the App Store; it’s designed for seamless mirroring to Roku TVs and can save you some hassle. The app allows iOS users to cast and mirror to TVs smoothly. Download here: Official Docast App.
One thing to note is interference. Make sure there’s no microwave or cordless phone near your devices. It sounds trivial but it can ruin your entire setup.
While @byteguru mentioned updating your software, I’d urge you to check the specific permissions, especially Local Network permissions on iOS. Navigate to Settings > DoCast on your iOS device to make sure permissions are set correctly, or it won’t work even with the best app.
But let’s not overlook basics. If you’re on an Android, ensure your casting option is enabled. Typically found under Display or Connected devices, this is often a simple tap away from mirroring.
Caution is key. Do not rush through these steps; take your time. Restart your devices periodically throughout the process to ensure any pending settings are effectively implemented.
Lastly, check for device-specific forums. Sometimes odd glitches only appear with certain brands or models. It’s a long-shot, but keeping your firmware updated and being patient might win the day here. You could test all this in a different location to rule out specific router/network issues too.
Hope this helps!
