In a world where every second counts, seamless connectivity between your devices and displays isn’t just a convenience—it’s a necessity.

Whether you’re running a high-stakes presentation, sharing a movie with friends, or expanding your desktop workspace, TransAir4 makes it effortless. Here’s your ultimate guide to setting up and using it in seconds.
One Receiver, Unlimited Possibilities

For those who prefer simplicity, the receiver-only configuration of TransAir4 offers a clean and minimalistic solution. With just one receiver, you can connect multiple devices without juggling multiple transmitters. The setup is straightforward and requires almost no technical know-how.
Step 1: Connect & Power
Plug the receiver into your display’s HDMI port. Use the included USB cable to power it—either through a wall adapter or a USB port on your monitor or TV. Once powered, the receiver lights up and is ready for pairing.
Step 2: Start Casting
On your phone, tablet, or computer, enable wireless/Wi-Fi and select Screen Mirroring (iOS) or the wireless display option (Android and Windows). Find “TransAir4” in the device list, enter the password displayed on the receiver, and start mirroring instantly.
Step 3: Select Input
Ensure your display is set to the HDMI input where the receiver is connected. With a correct input selection, your device screen will appear seamlessly on the big display.
Receiver-Only Connections for Mobile Devices

TransAir4 makes mobile casting intuitive for both iOS and Android users.
iOS Devices: Tap the floating control circle on your screen, swipe down to Screen Mirroring, and choose your TransAir4- device. Enter the PIN displayed on the receiver, and your screen is live in seconds.
Android Devices: Pull down your notification menu and tap the wireless screen mirroring icon. Select TransAir4- from the list and start mirroring immediately.

Receiver-Only Connections for Computers
Desktop users can also enjoy hassle-free wireless casting without additional transmitters.
Mac: Click the floating circle, swipe down to select TransAir4-, and enter the displayed password. Your Mac screen will appear instantly on your HDMI display.
Windows 10 & 11: Press Windows key + K, select TransAir4-, and begin wireless casting. It’s that simple.
One-to-One TransAir4: The Full Wireless HDMI Experience

For users seeking the ultimate control, the one-to-one configuration pairs a transmitter (TX) with a receiver (RX) for full-featured wireless HDMI streaming. This setup is perfect for high-performance needs like professional presentations, streaming, or classroom use.
Step 1: Power the RX
The receiver can be powered via a 5V power adapter or a USB port on your monitor or TV. Once connected, the RX is ready to receive signals from the transmitter.
Step 2: Connect RX to Display
Use the included HDMI cable to link the RX to your monitor or TV. This ensures high-quality video and audio transmission without complicated setups.
Step 3: Connect TX to Your Device
Plug the transmitter into a laptop, tablet, or smartphone. TransAir4 automatically establishes a wireless connection between the TX and RX, delivering your content with minimal delay.
Step 4: Control Your Casting
The TX button allows you to freely switch between displays or pause casting whenever necessary. This flexibility ensures that presentations, movies, or collaborative sessions run smoothly.
