NovaStar vs. Brompton — picking the right controller

The Architecture of Light Control: An Assessment

The visual impact of an LED wall is often falsely attributed solely to the quality of the installed diodes. However, while pixel pitch and component technology (SMD vs. COB) define the physical resolution, the controller – the brain of the infrastructure – determines the actual image stability, colour depth, and operational reliability. In professional system integration, planners usually face a binary fundamental decision: NovaStar or Brompton Technology. This choice is not a pure question of cost, but a decision regarding the technological roadmap of a system over the next seven to ten years.

Historically, the separation was sharply defined. With countless models from the MCTRL series to the VX all-in-one controllers, NovaStar served the mass market and large-scale retail installations. Brompton, on the other hand, positioned itself in the niche of live events and high-end film production with a focus on colour accuracy and extremely low latency times. With the release of the NovaStar COEX series and the VMP (Vision Management Platform) ecosystem, the boundaries have shifted. Competition now takes place at a level that assumes native 4K and 8K workflows at 120Hz and 12-bit colour depth as the new standard.

NovaStar COEX: The Evolution of Scalability

NovaStar has made a radical break with the introduction of the COEX (Control Experience) series. The flagship, the MX40 Pro, marks the transition from purely functional signal distribution to software-centric image processing. A decisive advantage of NovaStar is vertical integration. Since a large proportion of the receiving cards installed worldwide (such as the A10s Pro) originate from NovaStar, the coordination between controller and panel is often seamless.

The technical relevance of the COEX series lies in its ability to perform complex colour adjustments directly in the controller. With features such as "Full Grey-scale Calibration" and "Multi-layer Floating Window Display", NovaStar addresses problems that previously required expensive external image processors. In a typical corporate scenario – such as an atrium with a 4K LED wall – the MX40 Pro allows precise control of HDR10 and HLG content at a bandwidth of up to 20 gigabits via the corresponding fibre ports.

A key aspect of the NovaStar world is the licensing model. While Brompton is often perceived as a "closed system", NovaStar offers an enormous range of hardware options, which can, however, increase system complexity. Here, technical know-how is required to extract the most economically and technically sensible configuration from the abundance of controllers – from the industrial KU20 to the high-end MX40 Pro.

Brompton Tessera: The Gold Standard for Colour Accuracy

Brompton Technology takes a different approach. The British company focuses on a manageable product range, namely the Tessera SX40 processor in conjunction with the XD Data Distribution Units. Brompton's philosophy is "Image Integrity". In environments where cameras film the LED wall (Virtual Production, broadcast), Brompton is currently considered the market standard.

The core of Brompton technology is "Dynamic Calibration". Unlike static calibration, which often sacrifices brightness to achieve uniformity, the Brompton system calculates the optimal drive for every single pixel in real time. The result is significantly higher peak brightness with a simultaneously expanded colour space. If a project requires skin tones to be reproduced absolutely naturally, for example, or if moiré effects must be avoided through precise shutter synchronisation (frame remapping), there is almost no way around Brompton.

An often underestimated factor is the software interface. While NovaStar has made enormous progress with the new VMP software, Brompton's Tessera interface is considered the most intuitive on the market. In operational environments where technicians must change configurations under time pressure, Brompton minimises the risk of error through clear, visual feedback of the signal flow.

Technical Comparison: The Hard Facts

To be able to objectify the decision, an examination of the technical parameters of the current top models is necessary.

The table illustrates that on paper, both systems achieve similar performance values. Differentiation occurs in the details: through the combination of SX40 and the XD distribution units, Brompton offers a superior fibre optic topology, which is particularly advantageous for large distances in stadiums or event halls. NovaStar, on the other hand, scores with a higher density of on-board features for scaling and layering, which saves the use of an additional video switcher in many fixed installations.

Practical Example: Global Headquarters of an Industrial Group

Setting: An Austrian industrial group is equipping its new foyer with a 12-metre wide fine-pitch LED wall (pixel pitch 1.2mm). The wall serves both representative brand content and quarterly town hall meetings that are streamed worldwide.

Requirement:

• 100% reliability during the board stream.
• Easy operation by the internal facility management team.
• Excellent display of Corporate Identity colours (specific blue and orange).

Solution: In this case, the choice fell on a NovaStar COEX system with two MX40 Pro controllers in a redundant cluster. Why? Since the content is primarily fed from a media server and no extreme camera synchronisations (as in a film studio) are necessary, NovaStar offers the better price-performance ratio here. The VMP software allows the technician to call up predefined presets for "Daylight" and "Evening Event" at the touch of a button. The savings on controller hardware compared to a full-scale Brompton system could be invested in a higher LED batch with better binning values, which benefited the overall image quality.

Challenges in Signal Processing: Latency and Frame Rate

In projects where interactivity is required – such as sensor-controlled installations or in the gaming sector – latency becomes the critical path. Brompton is ahead here with its "Ultra Low Latency" mode, especially when the entire signal chain from the GPU to the panel is optimised. NovaStar has caught up with the ShutterFit algorithm in the COEX series to suppress flickering during recordings with high frame rates, which is essential for visitors' modern smartphone cameras.

Another standard gaining importance is the Accessibility Standard (BFSG 2025) and ecological requirements such as EU Regulation 2021/341 on the energy efficiency of displays. Modern controllers must be able to adjust the brightness of LED walls to the ambient light not just in stages, but via fine-grained characteristic curves (gamma curves). Both manufacturers offer sensor connections for this, however, integration into higher-level building management systems (KNX, Crestron) is often easier to implement with NovaStar due to the widely available protocol documentation.

What We See in Practice

Daily work at Lumexo shows that the decision is often driven less by technology than by logistics and operations. Here are the most important findings from our last 50 large-scale projects:

1. The Receiving Card Trap: Many customers choose a high-quality panel without realising that it contains a standard receiving card that cannot exploit the potential of a high-end controller like the Brompton SX40 at all. The chain is only as strong as its weakest link.
2. Software Adaptation: Switching from the old NovaLCT software to the new VMP platform is a big step for many existing customers. VMP is powerful but requires a more modern IT infrastructure in the background.
3. Maintainability: In long-term observation, Brompton systems often show higher stability of firmware releases. NovaStar releases updates more frequently, which brings new features but means higher testing effort in the context of validated IT environments in banks or insurance companies.
4. Spare Parts Management: Thanks to NovaStar's market dominance, replacement components are often available in Austria and Germany within 24 hours. At Brompton, availability is also excellent but concentrated on specialised rental houses.
5. HDR Complexity: Real HDR content in public spaces often fails not because of the controller, but because of the content. Both NovaStar and Brompton require metadata-based signals to really play out the dynamic range. Without professional mastering, the expensive controller remains underchallenged.

Economic Efficiency and Lifecycle Management

A NovaStar system is usually circa 30% to 50% cheaper to purchase than a comparable Brompton configuration. However, this price difference is relativised in projects with extreme service life or extreme requirements for troubleshooting. Brompton's diagnostic tools are more precise in the event of a fault (e.g. a defective data cable at a height of 10 metres) and save technician costs.

For operators of digital out-of-home (DOOH) advertising spaces managing hundreds of screens, NovaStar is often the logical choice due to the VNNOX cloud management system and integration into the Taurus series (TB models). Here, it is less about the last bit of colour depth and more about automated monitoring and efficient remote management via 4G/5G connections.

Recommendation from Lumexo

The choice between NovaStar and Brompton should never be made in isolation. It is the result of a needs analysis that takes content, environment, and the operating team into account.

• Choose NovaStar (COEX/VMP) if you are looking for a highly scalable, feature-rich solution for corporate installations, retail, or DOOH, where an excellent price-performance ratio and deep system integration (in-wall scaling) are paramount.
• Choose Brompton Technology if your LED wall functions as a backdrop for TV broadcasts, is used in Virtual Production, or if you require the absolute highest colour accuracy available on the market for high-end luxury brands.
• Pay attention to certifications: Ensure that the chosen controller-panel combination meets all local standards, especially regarding EMC testing and the upcoming Accessibility Strengthening Act (BFSG 2025).
• Plan the infrastructure holistically: A high-end controller requires an adequate signal source. Do not invest in an MX40 Pro or SX40 if the player only delivers compressed 8-bit signals.
