What Is NovaStar H5 and How Does It Work with LED Displays?
The NovaStar H5 is a professional modular video wall splicer designed for large and fine-pitch LED display systems.
Although many LED buyers call it an H5 video processor, NovaStar's official product name is:
H5 Video Wall Splicer
The H5 integrates video processing and video control and can also operate as a pure splicing processor. Its modular design allows different input and output cards to be installed according to the requirements of each LED project. H5 Video Wall Splicer Specifica…
For B2B LED projects, this makes the H5 particularly useful when a screen requires large pixel capacity, multiple video sources, multi-window display, 4K/8K signals or professional backup and monitoring.

1. What Is the NovaStar H5?
The H5 is a 5U modular video wall splicer developed for professional display systems, especially fine-pitch LED screens.
Its modular architecture means the chassis does not have one fixed connector configuration. Instead, users can select input and output cards based on the project.
The H5 supports hot-swappable cards and can be configured for applications including:
- Fine-pitch LED video walls
- Large indoor LED screens
- Control rooms
- Theatres
- Stage displays
- Exhibition halls
- Broadcast systems
- Corporate presentation spaces
NovaStar describes the H5 as suitable for exhibitions, presentations, production scheduling, radio and television, education, scientific research and stage rental applications. H5 Video Wall Splicer Specifica…
This flexibility is one of the main differences between the H5 and a simpler fixed-interface LED video processor.
2. NovaStar H5 Key Specifications
According to the official H5 Video Wall Splicer Specifications V1.17.0, the main chassis specifications are:
| Specification | NovaStar H5 |
|---|---|
| Rack Unit | 5U |
| Maximum Input Cards | 10 |
| Maximum Input Channels | 40 |
| Maximum Output Cards | 3 |
| Maximum Output Channels | 12 |
| Maximum Layers | 48 |
| Power Consumption | 400 W |
| Dimensions | 482.6 × 532.8 × 228.2 mm |
| Net Weight | 17 kg |
| Typical Noise | <45 dB(A) |
H5 Video Wall Splicer Specifica…
For LED display buyers, the most important specifications are usually:
Input Capacity + Output Capacity + Total Pixel Loading + Layer Quantity
These determine whether the H5 is suitable for the required screen and content system.
3. How Much LED Screen Can H5 Load?
One of the most important questions is:
How many pixels can a NovaStar H5 control?
There is no single answer because the maximum capacity depends on the installed LED sending cards.
The H5 supports up to three output cards. According to NovaStar's system specification, the maximum H5 loading capacity can reach:
| LED Sending Card Configuration | H5 Maximum Loading Capacity |
|---|---|
| H_16xRJ45+2xfiber | 31.2 million pixels |
| H_20xRJ45 | 39 million pixels |
| H_4xfiber | 62.4 million pixels |
| H_4xfiber Enhanced | 78 million pixels |
H5 Video Wall Splicer Specifica…
The individual sending cards themselves support different capacities. For example, one H_16xRJ45+2xfiber card can load up to 10.4 million pixels, while one H_4xfiber card can load up to 20.8 million pixels. The higher total figures above are based on the H5 chassis supporting up to three output cards.
How to Calculate Your Screen
Use:
Total Pixels = Horizontal Resolution × Vertical Resolution
For example, an LED screen with a resolution of:
4736 × 3584
contains approximately:
16.97 million pixels
The total pixel count should then be compared with the selected H5 sending-card configuration.
This is why buyers should never select a processor using only the physical screen dimensions.
4. What Inputs and Outputs Does H5 Support?
The H5 is designed for projects that use multiple signal types.
Depending on the installed input cards, supported interfaces include:
HDMI, DisplayPort, DVI, SDI, VGA, CVBS, HDBaseT, IP, NDI, ST 2110 and optical fiber.
The official specification also confirms support for 10-bit video source processing and 4K high-definition inputs and outputs. H5 Video Wall Splicer Specifica…
This means a professional system could connect several sources such as:
Media Server + PC + Camera + Presentation System + Broadcast Feed
and manage them through one H5 platform.
For LED output, H5 supports several sending-card options, including:
H_16xRJ45+2xfiber, H_20xRJ45, H_4xfiber and H_4xfiber Enhanced. H5 Video Wall Splicer Specifica…
Some sending cards also support optical transmission. The H Series manual explains that optical ports can be connected through fiber converters for long-distance signal transmission to the LED display. H Series Video Wall Splicers Us…
This is useful when the control equipment is located far away from the screen.
5. Multi-Layer, 4K/8K and HDR Support
The H5 is useful not only because of its pixel capacity, but also because it can build complex screen layouts.
The complete H5 system supports up to:
48 layers

A single processing card can support up to:
16 × 2K layers,
8 × DL layers,
4 × 4K layers, or
2 × 8K layers. H5 Video Wall Splicer Specifica…
This is useful when an LED wall needs to display several sources simultaneously.
For example, a control-room display may show:
Camera Feed + Dashboard + Map + Video + Computer Signal
on one LED screen.
The H5 also supports high-resolution input formats. Depending on the selected input card, HDMI 2.1 can support up to 8192 × 4320 @ 30Hz, while DP 1.4 also supports 8K-class input formats. H5 Video Wall Splicer Specifica…
Other image-processing features include:
HDR10, HLG and 10-bit processing, providing greater flexibility for professional high-quality content. H5 Video Wall Splicer Specifica…
6. Where Is NovaStar H5 Used?
The H5 is generally more suitable for medium-to-large professional LED systems than for simple small screens.
Fine-Pitch LED Video Walls
For meeting rooms, corporate showrooms and command centers, H5 can manage high-resolution LED walls and multiple signal sources.
Giant Indoor LED Screens
Its large pixel capacity makes it suitable for high-resolution LED displays in theatres, auditoriums and large commercial spaces.
Theatre and Stage LED Systems
A theatre may need to switch between a media server, camera, computer and other content sources.
H5 can process these sources and send the final composition to the LED screen.
Control Rooms
Multi-screen management and multiple video layers make H5 suitable for applications that require several monitoring windows simultaneously.
Exhibitions and Presentations
Preset management and flexible signal switching can simplify repeated presentations and event workflows.
7. When Should You Choose H5?
The H5 is worth considering when your LED project requires:
- A large total pixel count
- Multiple HDMI, DP, SDI or other inputs
- Multiple video windows
- 4K or 8K sources
- Several LED screens
- Long-distance fiber transmission
- Backup configuration
- Centralized monitoring
- Future system expansion
However, H5 is not automatically the best choice for every LED display.
For a small screen using one HDMI source and a relatively low total resolution, a simpler NovaStar processor may already be sufficient.
JunChen Display Recommendation
Do not select H5 simply because it is a higher-level processor.
First determine:
Screen Resolution → Input Sources → Layer Quantity → Output Capacity → Transmission Distance → Backup Requirement
Then choose the processor and cards.
This usually produces a more economical and reliable LED control system.
8. How to Configure H5 for an LED Display
Before ordering an H5, the LED supplier or system integrator should know the basic project requirements.
| Project Requirement | Information Needed |
|---|---|
| Screen Size | Width × height |
| Pixel Pitch | P1.25 / P1.5 / P2 / P2.5 etc. |
| Total Resolution | Width × height pixels |
| Input Sources | HDMI / DP / SDI / media server |
| Number of Sources | How many signals |
| Layers | Number of simultaneous windows |
| Transmission | Ethernet / optical fiber |
| Backup | Required or not |
| Screen Quantity | Single or multiple screens |
A typical LED system workflow is:
Media Server / Computer / Camera → NovaStar H5 → LED Sending Card → Ethernet or Fiber → Receiving Cards → LED Display
The H Series manual confirms that sending cards can connect through Ethernet to the LED display, while optical output can be used for long-distance transmission. H Series Video Wall Splicers Us…
Therefore, H5 should be considered as part of the complete LED control system, rather than as an independent device.
