2. Main Features

The NovaStar TU4K Pro focuses on simple setup, smooth control, and reliable playback. Below is a clear look at the core features that matter in actual use.

2.1 Intelligent Configuration

The TU4K Pro is built to make the first setup as simple as possible. Most of the work can be handled with a phone instead of a laptop or extra tools.

You open the app, connect to the controller, and start the scan. The TU4K Pro detects the LED receiving cards, finds the right configuration files, and applies them on its own. For a standard LED wall, this process usually finishes within a few minutes.

The controller includes an offline recognition algorithm. It reads the cabinet layout and links the screen automatically, even when the device is not connected to the cloud.

Basic calibration does not require special equipment. You take a photo with your phone, and the system clears the scan lines and aligns the modules.

2.2 User Interaction and Daily Control

NovaStar redesigned the interaction layer on the TU4K Pro. Both the on-screen menu and the physical interface are easier to use than older models.

The system uses a simpler visual structure and smoother transitions. Key options—such as source switching, brightness, and picture adjustment—are easier to reach.

The OSD menu can be called up with a single action. This helps during live playback when you must adjust brightness, scale, or source without interrupting the content.

The system includes a touch-assist sidebar. It provides shortcuts for tasks like split-screen control, input switching, and local playback.

2.3 Playback and Program Management

The TU4K Pro supports several playback paths. You can display content from a USB drive, internal storage, mobile mirroring, or cloud-based management.

2.4 Wireless Mirroring and Multi-Source Display

Wireless mirroring is one of the TU4K Pro’s main strengths.

The device supports multiple mirroring modes for phones and laptops.

In stable network conditions, it can stay connected for long periods—more than 72 hours without dropping. Latency stays below roughly 80 ms, which is suitable for meetings, documents, and general presentations.

The controller supports multi-window layouts. You can mirror several devices at the same time and arrange them into a nine-part grid.

2.5 Real-Time Monitoring and Maintenance

The TU4K Pro provides tools for monitoring and troubleshooting.

The system tracks brightness, temperature, connectivity, and communication status. It reports abnormal conditions early so users can respond before a failure occurs.

When an issue happens, the device provides an alarm and a short description. It helps locate the problem within the cabinet chain, receiving cards, or modules.

Configuration files can be stored in the cloud. If the device is reset or replaced, the system can recover the configuration with one click.

2.6 Hardware and Software Integration

The TU4K Pro combines several roles into one device:

LED display controller
Media player
Android host for conferencing apps
Network publishing endpoint
Wireless mirroring receiver

It has multiple expansion ports and supports flexible connection layouts. Users can switch between sources quickly and use the controller as the central node for most LED display tasks.

3. Where It Works Best

The TU4K Pro fits a wide range of LED projects, especially when users want a clean setup and reliable daily control. Below are the scenarios where it performs the best.

Meeting and Conference Rooms

The controller works well in meeting spaces because it supports wireless mirroring, low-latency display, and apps like Zoom and Teams.

Most users can walk into the room, connect their phone or laptop, and start presenting without extra hardware.

Corporate Lobbies and Reception Areas

For fixed content such as welcome messages or looped videos, the USB playback and internal storage make updates very simple.

You plug in a drive, update the files, and the screen plays them automatically.

Retail Stores and Shopping Malls

VNNOX cloud publishing helps retail locations update promotions quickly.

Chain stores can push content to multiple sites at once, which reduces on-site labor.

Training Rooms and Classrooms

The multi-window layout and smooth mirroring allow several users to share screens at the same time.

This works well for group discussions or side-by-side comparisons.

Small Exhibition Booths

When exhibitors need a quick setup without a full control system, the TU4K Pro is useful.

It plays videos, switches sources easily, and supports basic calibration without special tools.

4. Installation and Setup Experience

This section walks through the basic steps, from the first power-on to getting content on the screen.

If this is your first time using the device, follow the process below.

① First Power-On

When you turn on the TU4K Pro for the first time, the device guides you through a simple setup wizard.

Select the system language from the list.
This only takes a few seconds but helps make the following steps easier.

The device will display its own Wi-Fi hotspot name and password. You must connect your smartphone or computer to this hotspot to proceed with the setup. This is a mandatory step for the initial configuration.

Give the controller a clear name—such as “Meeting Room LED Wall” or “Lobby Screen.” This helps identify the device in the app or cloud platform later.

Note: The hotspot name will update automatically to match the new device name.

② Pairing the Remote Control

The remote control communicates through Bluetooth.

Point the remote at the device’s infrared sensor and hold down the Menu and Home buttons simultaneously until the Pairing with the remote prompt appears on screen. Once connected, you can control playback, switch inputs, or open the OSD menu quickly.

③ Using the Mobile App for Screen Configuration

Most users configure the screen using their phone.

Use the VNNOX Care app for screen configuration. Connect your phone to the device’s hotspot, open the app, and tap Connect to Hotspot.

The VNNOX Care app scans and identifies the connected receiving cards and cabinets. You do not need to search for files or match card models manually.

After confirming the layout in the app, the configuration is sent to the TU4K Pro, which then applies it to the screen. For standard screens, this usually finishes in minutes.

④ Cabinet Recognition and Basic Calibration

The VNNOX Care app can recognize the cabinet layout and connection topology using its camera.

When setting up a screen or verifying connections:

Open the topology tool in the VNNOX Care app
Take a clear photo of the powered-on full screen
The app processes the image to map the physical cabinet connections

This is a powerful tool for quickly establishing or verifying screen layout, which simplifies the initial setup process.

⑤ Adding Content

Once the screen is configured, you can display content in several ways.

Insert a USB drive into the front or rear USB port. The file system can be accessed via the File Explorer app on the device. You can play media directly or import files into the internal storage.

Upload content through the network or from a USB drive to the device’s internal storage. Use the built-in Media Player app to create, manage, and play programs. You can control playback using the remote or mobile app.

Phones and laptops can mirror their screens wirelessly. For best performance with 4K content, it’s recommended to use a 5GHz Wi-Fi network. The connection is stable for slides, documents, and general presentations.

For users managing multiple screens, cloud publishing is efficient. You create a program online in the NovaStar VNNOX and send it to the TU4K Pro remotely.
