What You'll Need Before Installation

Before you begin, it's worth taking a few minutes to verify that all components are included and in good condition. Missing accessories or damaged cables can slow down the installation process and lead to unnecessary troubleshooting later.

A standard Foldable LED Poster package typically includes:

• Foldable LED Poster cabinet

• LED display modules

• Media controller

• Power supplies

• Receiving cards

• Main power cable

• Ethernet cable

• Wi-Fi antenna

• Hex wrench

• Flight case (optional)

It's also recommended to prepare a clean, spacious work area. Since LED modules are precision components, keeping dust, moisture, and sharp objects away from the installation area helps protect the display during assembly.

Pro Tip: Before connecting any cables, check that the power is switched off. This helps prevent accidental damage to internal components during installation.

Step 1: Installing the LED Poster Cabinet Components

The cabinet serves as the structural foundation of the entire Foldable LED Poster, so installing its internal components correctly is the first step toward a reliable display.

A properly assembled cabinet creates a solid foundation for installing the LED modules and helps ensure stable operation once the display is powered on.

Step 2: Install the LED Display Modules

With the cabinet prepared, the next step is installing the LED display modules that form the display surface.

Each LED module requires two connections before installation: the power ribbon cable and the signal ribbon cable. Make sure both cables are securely connected before placing the module onto the cabinet.

Install the modules one by one, following the correct sequence until the entire cabinet is covered. During installation, avoid applying excessive pressure to the LED surface, as this may damage the LEDs or affect the module alignment.

Install all modules one by one

Once every module has been installed, inspect the front of the display from different viewing angles. If you notice any uneven sections, adjust the magnets located on the back of the modules. These magnets allow you to fine-tune the position of each module, creating a perfectly level display surface.

Although this adjustment only takes a few minutes, it has a significant impact on the final visual quality. Even slight differences in module alignment can become noticeable when displaying bright images or large areas of solid color.

A perfectly flat screen surface is essential for delivering a seamless viewing experience and achieving the best possible image quality.

After confirming that all modules are aligned correctly, the LED display assembly is complete.

Step 3: Setting Up the LED Display Media Controller

Once the LED modules have been installed, the next step is to set up the media controller. This component acts as the "brain" of the LED Poster, receiving content from HDPlayer and controlling how images, videos, and text are displayed on the screen.

Begin by removing the controller mounting base from the cabinet. Securely fasten the media controller to the base using the supplied screws, ensuring that it is firmly fixed before connecting any cables.

Next, install the Wi-Fi antenna. Start by inserting the antenna connector through the mounting hole, then install the inner washer, outer washer, and retaining nut in the correct order. Tighten the nut with pliers before attaching the antenna.

Although the antenna is a small component, it plays an important role. It provides wireless communication between the LED Poster and your computer or mobile device, allowing you to upload content and configure the display without a wired network connection.

After the antenna has been installed, connect the two Ethernet cables and the power cable to their corresponding ports on the media controller. These connections allow the controller to communicate with the receiving cards and distribute image data across the entire display.

Install and wire the control board and antenna onto the base

Finally, slide the mounting base back into the cabinet and tighten the screws on both sides to secure it in place.

Before moving on, verify that every cable is fully connected and that the antenna is firmly installed.

Step 4: Uploading Content with HDPlayer

With the hardware installation complete, it's time to upload your content to the LED Poster.

HDPlayer is the control software used to configure the display, manage playback, and upload media files. It supports videos, images, text, and other multimedia content, making it easy to create dynamic digital signage for a wide range of applications.

Open HDPlayer to upload videos

To begin, connect your computer to the Wi-Fi network of the LED Poster using the SSID and password shown on the cabinet or controller label.

When HDPlayer is launched for the first time, it may automatically open the Screen Parameter Settings window if the display has not yet been configured.

You can either import the hardware configuration automatically or manually set the display resolution according to your LED Poster specifications.

Once the screen parameters have been configured successfully, the display information and program list will appear in the upper-left corner of the software interface.

To upload content:

• Click the rounded "+" button in the video list.

• Select a video from your computer.

• Preview the content to ensure it displays correctly.

• Click the green Send button to transfer the program to the LED Poster.

After the upload is complete, the content will begin playing on the display.

Besides video playback, HDPlayer also supports images, scrolling text, clocks, weather widgets, and other digital signage elements, allowing users to create engaging multimedia presentations without additional software.

Pro Tip: Before sending a large video file, preview the content in HDPlayer to confirm the resolution and aspect ratio match your LED Poster. This helps avoid image distortion or black borders during playback.

Step 5: Connect Multiple LED Posters

One of the biggest advantages of the Bi-fold LED Poster is its ability to create larger digital displays by connecting multiple units together.

Whether you're building a video wall for an exhibition, a stage backdrop, or a retail display, proper cabinet alignment and signal connection are essential for achieving a seamless visual experience.

Connect the Cabinets

Begin by positioning the LED Posters side by side.

Carefully align the cabinet edges before tightening the side connection locks with the supplied hex wrench. During this process, it's recommended that one person aligns the front surfaces while another secures the locking mechanisms from the side.

Daisy-Chain the Display Signal

After the cabinets have been physically connected, the display signal must also be connected.

Use the HDMI ports located at the bottom of each LED Poster to daisy-chain the displays.

When making the connections, remember the following rules:

• The left HDMI port is IN.

• The right HDMI port is OUT.

• Always connect the displays from right to left.

The first LED Poster only uses its OUT port.

The left port is IN, and the right port is OUT

Daisy chain the displays from right to left

Connect the OUT port of the first display to the IN port of the second display, then continue connecting the remaining displays using the same method until the entire display wall is complete.

This daisy-chain configuration allows video signals to be transmitted efficiently across every connected LED Poster without requiring individual content uploads.

Once all HDMI connections have been completed, content only needs to be uploaded to the first LED Poster in the chain.

All LED Posters have been connected

Pro Tip: Double-check the HDMI IN and OUT ports before powering on the displays. Incorrect connections are one of the most common causes of signal transmission issues during installation.

Step 6: Configure Canvas Settings

If you're using a single Bi-fold LED Poster, the default screen configuration is usually sufficient. However, when multiple LED Posters are connected to create a larger display, you'll need to configure the Canvas Settings in HDPlayer.

Configure the canvas using HDPlayer

Think of the canvas as the total display area recognized by the software. Without the correct canvas size, content may appear stretched, cropped, or displayed only on part of the screen.

For example, when the total display width exceeds the default configuration, HDPlayer must be told the combined resolution of all connected LED Posters. This allows the software to treat multiple displays as one seamless digital canvas.

When Is Canvas Configuration Required?

For Bi-fold LED Posters, Canvas Settings are required when more than five displays are connected.

If your installation consists of five or fewer displays, the default settings are generally sufficient.

How to Configure the Canvas?

Start by connecting your computer to the Wi-Fi of the first LED Poster in the display chain.

Open HDPlayer, then navigate to:

Control → Device Information

Expand the menu if necessary.

On this page, simply type hdadmin using your keyboard. No input box is required. After entering the password, additional configuration options will become available.

Select Canvas Settings.

Enter the canvas width according to the total number of connected LED Posters, then click Set to save the configuration.

Once the settings have been applied, upload your video or media program as usual. HDPlayer will automatically distribute the content across the entire display wall.

Pro Tip: Configure the canvas before sending your program. If you upload content first and then change the canvas size, you may need to resend the program to ensure it displays correctly.

Step 7: How to Unfold, Fold, and Pack a Foldable LED Poster

One of the biggest advantages of a Bi-fold LED Poster is its portability. Unlike traditional fixed LED displays, it can be folded for transportation and unfolded again within minutes, making it ideal for rental companies, exhibitions, roadshows, and temporary events.

Although the folding mechanism is designed for convenience, following the correct procedure helps protect the cabinet structure and ensures a longer service life.

Unfolding the LED Poster

Before unfolding the display, lock the built-in casters to prevent the cabinet from moving during operation.

Release the side latches and carefully lift the upper section of the cabinet until it reaches its fully opened position.

Once the display is fully extended, secure all folding locks to keep the cabinet stable during use.

Before powering on the display, check that every folding lock has been tightened completely.
