In response to your concern regarding screen cast issue in Nokia 7 Plus, we would like to request you to kindly follow the below steps:
I would like to inform you that You need to use Chromecast device to stream directly from TV.
Step 1) Download Google Home Application from Play Store.
Step 2) Connect your device with your cast device through Wi-Fi.
Step 3) Then set your Cast Device in TV and TV in HDMI mode.
Step 4) Let your Device search your Cast Device In Google Home Application then your Cast ask to connect with Router.
Step 5) Now connect your device with Router and start streaming.
But when I try to cast atleast I should able to see nearby devices
