The connection is established locally between devices, so the data transfer speed depends only on the power of the Wi-Fi modules of the TV and smartphone. This ensures minimal latency when displaying images, which is critical for gaming or demonstrating presentations.

Is it possible to mirror an iPhone's screen to a Xiaomi TV without a router?
Yes, this is possible if your TV model natively supports the AirPlay 2 protocol (often found in newer Google TV models). Otherwise, you'll need to install an AirPlay emulator app, such as AirScreen, on your TV to create the necessary connection environment.
Why is there no sound when connected via Wi-Fi Direct?
Most often, the problem lies in the audio settings on the phone itself. Make sure the audio output device is set to HDMI or a wireless device, not the phone's speaker. Also, check if the phone is in "Do Not Disturb" mode, which could block the audio stream.
Does Wi-Fi Direct affect internet speed?
Yes, it does. Since a smartphone's Wi-Fi module cannot simultaneously operate as a client (for the internet) and an access point (for the TV) at full power, the phone's internet speed may drop, or the internet connection may be temporarily disconnected during active streaming.
How do I disable the confirmation prompt on my TV?
In most cases, the confirmation request (PIN or "Accept" button) is a security measure and cannot be completely disabled in the default settings. However, if the devices have been previously paired, reconnection often occurs automatically without prompting.
