Dual-Display Upgrade: Everglory J1900 1-to-2 LVDS Commercial X86 All-in-One Solution

What is the Everglory J1900 Dual-Display Solution

The Everglory dual-display solution for commercial X86 all-in-one PCs is a professional 1-to-2 LVDS display solution built on our self-developed J1900 industrial motherboards.

Conventional J1900 motherboards on the market only support single-channel LVDS output and can merely drive one display screen, failing to meet the multi-screen presentation demands of commercial scenarios.

Through in-depth hardware circuit redesign and independent development of low-level drivers, Unitech has enabled 1-to-2 LVDS output on a single J1900 motherboard. It can drive two display panels simultaneously, with free switching between clone (synchronous) mode and extended (asynchronous) mode.

This solution requires no external adapter boards or dual motherboard stacking. A single motherboard is capable of delivering either identical or differentiated content on two screens. Featuring compact structure, excellent compatibility and reliable operation, it is tailor-made for dual-screen X86 devices used in commercial environments.

Why This Solution Is Essential for Commercial Scenarios

Dual-screen linked display is widely required in scenarios such as commercial displays, supermarket guidance terminals, government service counters, self-service kiosks and dual-screen digital signage. Most traditional X86 dual-screen devices adopt dual motherboard assembly or external adapter modules for dual display output. Such solutions lead to bulky enclosures and messy internal wiring, and often suffer from image lag, color distortion, system crashes and synchronization errors. They also bring high costs for hardware procurement and on-site deployment.

Conventional J1900 motherboards with single-channel LVDS output cannot drive two displays on one single board, which greatly restricts equipment integration. Our self-developed J1900 1-to-2 LVDS solution thoroughly addresses these industry pain points. Built on the mature and reliable X86 architecture, it delivers solid computing performance and powerful dual-display capabilities. It supports synchronous content playback for promotional use, as well as independent asynchronous output on the main and secondary screens. This solution effectively cuts failure rates and overall project costs, fully meeting the market demands for commercial devices that feature lightweight design, high integration and outstanding stability.

Key Parameters for Selection

1.Dual Native LVDS Output: Adopts J1900 motherboard with native one-to-two design. No adapter board required, effectively eliminating signal attenuation, screen flickering and image tearing issues.

2.Dual-mode Compatibility: Supports both clone and extended display modes. Switch with one click via software, compatible with various commercial display scenarios.

3.Wide Resolution Compatibility: Works with screen combinations of the same or different sizes, delivering stable output for various HD resolutions.

4.X86 System Compatibility: Fully compatible with Windows systems and various commercial playback software, cashier systems and public display software.

5.Overall System Stability: The driver is integrated on a single motherboard, featuring balanced heat dissipation and low interference. It runs smoothly without lag or screen dropout even during long-term operation.

Common Issues in Design, Installation and Testing

1.Difficult dual-screen expansion with general motherboards: Regular J1900 motherboards only feature single-channel LVDS output, requiring external adapter modules which lead to poor compatibility and high failure rates.

2.Unstable signals from adapter boards: External expansion solutions often cause issues including unsynchronized dual screens, obvious color deviation, screen flickering, blackouts and screen disconnection.

3.Limited asynchronous playback: Most modified solutions on the market only support clone mode and cannot realize independent asynchronous display on dual screens.

4.Redundant dual-motherboard structure: Traditional dual-motherboard solutions come with messy wiring, concentrated heat buildup, bulky device size and high operation & maintenance costs.

Recommended Configuration Solution

The complete device is equipped with the self-developed industrial-grade J1900 main control motherboard by Everglory. It features native hardware-based 1-to-2 dual-channel LVDS display output, requiring no external adapter devices and ensuring stable signal transmission at the underlying hardware level. Fully compatible with the stable Windows 10 system, it adapts to most commercial terminal software, advertising publishing systems and data interaction programs. It supports free switching between dual-screen synchronous clone mode and asynchronous extended mode, and can be flexibly matched with display screens of various specifications, delivering high-definition images without ghosting or flickering.

Taking advantage of the low power consumption and high stability of the J1900 X86 architecture, the device achieves balanced heat dissipation and supports 7×24-hour non-stop operation. It also supports vertical and horizontal screen switching, remote background management, and scheduled start-stop functions. Adopting a minimalist single-motherboard architecture, it delivers high-end dual-screen display effects at low cost, suitable for various commercial dual-screen device application scenarios.

Relevant Application Cases

The device features a main screen for checkout operations and a secondary screen dedicated to playing promotional ads and event content independently. The original solution used a standard J1900 mainboard paired with an external adapter board, which led to frequent malfunctions such as screen flickering, dual-screen out-of-sync, asynchronous function failure, system crashes and unexpected reboots. These issues severely hampered daily business operations.

After adopting Everglory self-developed J1900 1-to-2 LVDS dual-screen X86 all-in-one board, a single mainboard can stably drive two screens for independent asynchronous operation. The images play smoothly with no latency and uniform color presentation. The overall device structure is greatly simplified, and the failure rate drops substantially. The total hardware and operation & maintenance costs of the project are reduced by 35%. Since mass deployment, all units have run reliably, fully complying with the long-term demands for commercial display and self-service operations in supermarkets.

Conclusion

Commercial X86 dual-screen display scenarios have long been plagued by industry challenges: standard motherboards only support single-channel output, adapter-based solutions suffer from instability, and dual-mainboard setups come with excessive costs.

Everglory’s self-developed J1900 1-to-2 LVDS dual-screen solution leverages the proven performance of the X86 architecture. With dedicated upgrades to hardware and drivers, it enables a single motherboard to freely switch between dual-screen synchronous and asynchronous modes. This completely resolves the drawbacks of traditional solutions, including bulky structure, unstable signals and high costs.

Priority should be given to native dual-channel LVDS output, dual-mode compatibility and system adaptability during selection, to effectively avoid defects of retrofitting solutions. Featuring high integration, outstanding stability and cost efficiency, this solution delivers standardized and lightweight X86 dual-screen display options for commercial applications such as supermarket self-service terminals, chain stores, government information bulletin systems and advertising media.
