ARLED SIRIUS Pro Cinema LED Wall — engineered for the private cinema

The SIRIUS Pro Cinema LED Wall is an in-house development by ARLED Cinema, built on the 5G High Performance COB+ platform with the latest XM+ technology. It is not an adapted commercial display. It is a purpose-built home cinema LED wall designed from the ground up for private screening rooms that demand reference-grade image quality.

With a pixel pitch of 0.84mm, a contrast ratio exceeding 1,000,000:1, and a brightness of 1,400 nits, the SIRIUS delivers an image that no projector — regardless of price — can match in terms of black depth, color accuracy, and uniformity. There is no lamp to replace, no screen to align, and no brightness degradation over time.

Available screen sizes and resolutions

The SIRIUS is built from two standardised cabinet sizes (Cabinet A: 806 × 454mm, Cabinet B: 403 × 454mm), which combine to achieve a wide range of screen dimensions — from compact UHD installations to massive 8K walls.

• 564 × 318 cm — 6720 × 3780 px — Format 1.78:1
• 645 × 363 cm — 7680 × 4320 px — Format 1.78:1 (8K)

Custom sizes are available on request. Every installation is planned individually based on room dimensions, seating distance, and viewing angle.

Why COB+ technology makes the difference

The SIRIUS uses Full flip-chip COB+ (Chip-on-Board) technology with a matte black surface coating. Unlike conventional SMD LED displays, COB+ encapsulates the LED chips directly into the board without individual lens covers. The result is a dramatically improved contrast ratio, superior resistance to physical damage, and a uniformly dark surface that does not reflect ambient light. Compared to conventional LED technology, COB+ delivers 40% energy savings and a 1,000,000:1 contrast ratio.

The XM11206G chip

The XM11206G at the heart of the SIRIUS delivers 18-bit high colour depth and supports low grayscale performance at high refresh rates — with a 16-fold improvement in refresh rate at low grayscale, eliminating flicker visible to the human eye. It supports front-end high framerate input from 23Hz to 480Hz, with a visual refresh rate of up to 15,360Hz.

The Mirage Driving Engine solves eight fine-pitch visual issues simultaneously: ghosting effect, open caterpillar effect, cross effect, low gray colour shift, first dimming line, high contrast couple, and cross plate gradient CCT.

Intelligent image processing

Gray Scale Extension increases the effective output bit depth, resulting in smoother and more natural gradients while revealing finer details in darker areas.

Multi-Level Calibration eliminates mottling and color blocking at different gray levels, ensuring uniform and consistent display across all brightness levels. Each gray scale has its own calibration coefficient.

Thermal Compensation actively monitors and corrects color shift caused by uneven heat distribution during long screening sessions — ensuring consistent colour accuracy after hours of continuous operation.

Dynamic Booster converts SDR content to near-HDR quality in real time, saving 20–40% power consumption while preserving detail in both bright highlights and deep shadows.

Image Booster delivers 22bit+ with 64-times grayscale improvement and 0.002 nits precise control for stunning realism.

Colour Adjustment matches the gamut of the display to the gamut of the video source, eliminating color bias and reproducing the original colour exactly as intended.

Installation and reliability

Each cabinet features bi-directional mounting holes on all four corners, supporting both front and rear installation. VESA mount compatibility is included as standard. Customised connectors allow six-way adjustment of each module, ensuring superb flatness across the entire screen surface.

A dual backup system for both the power supply and receiving card guarantees uninterrupted operation. If the primary system fails, the backup switches over automatically without any visible interruption to the display.

Planned, installed and calibrated by ARLED Cinema

ARLED Cinema handles the complete planning, installation, and calibration of every SIRIUS Pro Cinema LED Wall — from room acoustics and screen sizing to signal chain integration and colour calibration. Every installation is tailored to the individual room and client requirements.
