If you’ve ever tried connecting a laptop to a TV using cables, you already know the hassle. Crouching behind the TV, fumbling with HDMI ports, searching for the right outlet—it’s a routine that feels outdated. The Lemorele P400 wireless video transmission kit changes that with a cleaner, faster, and more flexible way to share your screen. Built for home entertainment, presentations, teaching, and mobile work, the P400 lets you go fully wireless—without setup headaches.

1. Step-by-Step Setup That Makes Sense

Here’s exactly how the setup process works in real use. No guessing. No IT support needed.

1.1 Connect the Transmitter (TX) to Your Laptop

Plug the TX unit into your laptop’s HDMI port. Use the included USB-C cable to power it.

• No drivers to install

• No system changes needed

• No settings to configure

You just plug it in and wait a few seconds. The device becomes active without user prompts.

1.2 Connect the Receiver (RX) to the TV

Insert the RX into any HDMI port on your TV. Power it with USB-C—either from the TV’s USB port or a standard wall adapter. The receiver powers up and starts listening for the TX signal.

1.3 Wait for Automatic Pairing

There’s no manual pairing process. Once both devices are powered, they connect automatically.

• No network setup required

• No buttons to press

• No on-screen configuration

The TV mirrors the laptop screen in 5 to 10 seconds. You’re ready to present, stream, or play.

2. Immediate Benefits You Can See and Hear

2.1 Smooth, Synchronized Playback

The screen on your TV updates as quickly as your laptop.

• Full HD 1080P@60Hz streaming

• Sound and video remain in sync

• No noticeable input lag or frame drops

Even during fast-forwarding, app switching, or video playback, everything stays smooth.

2.2 Clutter-Free Environment

The P400 eliminates the need for long HDMI cables running across rooms.

• Devices stay where you placed them

• No rearranging furniture to get closer to ports

• Both TX and RX are compact and low-profile

The setup looks clean and feels effortless.

3. Built for Everyday Use

3.1 No Apps, No Interfaces

The P400 does not rely on additional apps or companion software.

• There are no QR codes to scan

• No mobile app to download

• No login screens to deal with

If you can plug in a cable, you can operate this kit.

3.2 Works with Nearly Every Device

Three supported modes let it adapt to your tech ecosystem:

• TX-RX mode for a stable, dedicated signal path using HDMI

• AirPlay mode for iPhone, iPad, and macOS users

Whether you're on Windows, Android, iOS, or macOS, it fits right in.

4. Real Scenarios Where It Makes a Difference

4.1 Living Room Entertainment

You don’t need to move your laptop near the TV. Just leave it on the coffee table.

• Start the video

• Let the image appear wirelessly on the big screen

The experience feels as if the devices were already connected.

4.2 Office Presentations

You arrive in the meeting room, plug in the transmitter, and get started right away.

It keeps the focus on the content, not the equipment.
