Wireless screen mirroring is no longer used only for presentations. Today, many users rely on wireless transmission for streaming movies, watching online content, and building flexible home entertainment setups. The challenge is that not all wireless modes behave the same—especially when streaming platforms, latency, and stability are involved. The Lemorele P400 wireless video transmission kit addresses this by supporting three different connection modes: Miracast, AirPlay, and TX-RX. Each mode works differently at the system level and is suitable for different streaming and display scenarios. This article explains how these three modes work, how they differ, what they have in common, and how to choose the right mode for streaming media, meetings, and daily use.

1. What P400 Is and Why Connection Mode Matters

P400 is a wireless video transmission kit made up of two physical units: a transmitter (TX) and a receiver (RX). In use, the TX stays near the source device, while the RX remains connected to a TV, monitor, or projector. Both units support 1080P at 60Hz, operate on the 5GHz band, and maintain low latency at around 50 milliseconds under stable conditions. Power is supplied through USB-C at 5V/2A, and no drivers or apps are required to get started.

What sets P400 apart in everyday use is that it does not lock the user into a single mirroring method. Instead, it offers three connection modes. Each one behaves differently once the screen turns on, especially when streaming video or switching between devices. Understanding this difference early helps avoid trial-and-error later.

2. Miracast Mode

Miracast mode is intended for Windows laptops and Android devices that already support Miracast at the system level. In practice, setup usually starts by opening the device’s wireless display menu and selecting the receiver. Within a few seconds, the screen appears on the display without plugging anything into the source device.

For streaming, Miracast performs well when the system is lightly loaded. Web-based streaming services, local video files, and presentation slides with embedded video usually display without issue. The experience feels simple when the device, operating system, and Wi-Fi radio cooperate.

However, Miracast depends heavily on the operating system’s screen encoding and wireless handling. Background apps, system updates, or weaker Wi-Fi hardware can affect smoothness. In most environments, stable use stays within about 10 meters.

Common scenarios include streaming videos from a Windows laptop to a TV, casual screen sharing from an Android phone, or quick content sharing without connecting a physical transmitter.

3. AirPlay Mode

AirPlay mode is designed for Apple devices such as iPhone, iPad, and macOS laptops. Once enabled, the receiver appears as an available AirPlay display. The user selects it from the system menu, and both video and audio route automatically to the screen.

In daily use, AirPlay feels familiar to Apple users. Streaming apps, local video libraries, and browser playback usually work without manual audio adjustments. This makes it comfortable for home viewing and light entertainment.

Like Miracast, AirPlay relies on OS-level encoding and wireless conditions. Performance is generally stable within a 10-meter range, but heavy network traffic or background processes can affect playback during longer sessions.

Typical use includes streaming movies from an iPhone to a living room TV, sharing MacBook screens during meetings, or casual home entertainment within the Apple ecosystem.

4. TX-RX Mode

TX-RX mode is the most predictable and stable mode of P400, especially for streaming-focused setups. Instead of relying on system-level mirroring, the TX connects directly to the source device through HDMI, while the RX outputs HDMI to the display.

Once powered, the TX and RX establish a dedicated 5GHz wireless link. From the user’s perspective, this feels similar to using an HDMI cable, except without the physical wire. The operating system plays no role in encoding or wireless negotiation.

This makes TX-RX mode ideal for streaming sticks, TV boxes, consoles, and long viewing sessions. Streaming apps run directly on the source device, and P400 transmits the video signal as-is. The result is higher stability, consistent audio-video sync, and fewer interruptions over longer distances of up to 50 meters in open environments.

Common setups include Fire TV Stick streaming to a TV or projector, cable-free home theater layouts, and exhibition spaces where content runs continuously throughout the day.

5. Comparing the Three Modes in Practice

Despite their differences, all three modes deliver Full HD 1080P at 60Hz, maintain audio and video synchronization, and operate on the 5GHz wireless band. None require drivers, apps, or manual pairing steps. The TX and RX remain compact and portable, allowing users to adapt the same hardware to different situations.

6. Choosing the Right Mode for Streaming

Miracast works best for fast, cable-free streaming from Windows or Android devices. AirPlay is well suited for Apple-based streaming and casual home viewing. TX-RX mode is the best option when stability matters most, such as with streaming sticks, TV boxes, projectors, or long playback sessions.

For users who watch streaming content regularly, TX-RX mode delivers the most consistent results, while Miracast and AirPlay provide flexibility and convenience.

8. Final Thoughts

P400 is not just a wireless screen mirroring device. It is a multi-mode wireless transmission system that adapts to different streaming and display workflows. Each mode balances ease of use, compatibility, and stability in a different way.

By understanding how Miracast, AirPlay, and TX-RX behave in real use, users can build a reliable wireless setup for home entertainment, meetings, and everyday viewing without drivers, apps, or complex configuration.
