How to Choose the Monarch Display Board?
2026-05-11
In the elevator components industry, the quality of a display board directly determines the passenger experience and the operational stability of the entire elevator system. NONA, as a professional manufacturer with many years of experience in elevator components, understands that choosing a high-quality Monarch display board is not only a guarantee of equipment performance but also a commitment to passenger safety. The MCTC-HCB series display board is known for its high compatibility, long lifespan, and accurate display. However, faced with a wide variety of products on the market—from entry-level LED display boards to high-end TFT touchscreens, from standard car displays to external call floor displays—many buyers often find themselves confused about which model is truly the "optimal solution" for their project needs.
This article will systematically break down the selection logic of the Monarch display board from three core dimensions: technical parameters, application scenarios, and compatibility matching, helping you avoid pitfalls and make the right choice in your procurement decisions.
I. Key Selection Criteria
1. Display technology type: LED vs LCD vs TFT
| Type | Applicable Scenarios | Advantages | Model |
|---|---|---|---|
| LED Display | Conventional scenes such as residences, shopping malls, hotels, etc. | Low energy consumption, long life, vibration resistance, low maintenance cost | MCTC-HCB-D634 |
| LCD Display | Office buildings, hospitals, high-rise buildings | Clear display, multi-language support, large information capacity | MCTC-HCB-U670 |
| Picture TFT Display | High-end hotels, business centers, luxury residences | High resolution, bright colors, support for multimedia content | MCTC-HCB-T640 |
2. Installation location and function positioning
3. System compatibility verification
II. Frequently Asked Questions
Q1: Can the Monarch display board be mixed with other brands of elevator control systems?
A1: In principle, it is not recommended. Monarch display boards use the proprietary MCTC communication protocol. Although some general-purpose models can achieve cross-brand compatibility through protocol conversion, there will be risks of display delays, loss of functions, or reduced stability. In order to ensure the best performance of the system, it is recommended that the display board and main control system use Monarch's original supporting products. If you really need to modify and upgrade, be sure to contact professional technicians for protocol compatibility testing.
Q2: How to determine whether the display board is genuine from Monarch?
A2: There are some imitations and refurbished parts on the market. Key points for identification include:
Model identification: Genuine boards are clearly printed with "Monarch" or "MCTC" and the complete model code.
PCB process: The original board has full solder joints, standardized wiring, and neat component layout.
Software verification: read the display board parameters through the main controller, genuine products can be recognized normally and display complete function codes
Channel traceability: Choose suppliers with Monarch official authorization or long-term stable cooperation qualifications like NONA.

Q3: How should we deal with abnormal display on the display board (garbled characters, missing lines, and no light)?
A3: It is recommended to follow the following steps to troubleshoot:
Power supply check: Confirm that the 24V power supply voltage is stable and the wiring terminals are not loose.
Communication detection: Check whether the CAN bus or serial communication line is in good contact and whether the terminal resistance matches.
Parameter verification: Check whether the display board address code (Floor Address) is set correctly through the main controller operation board.
Hardware replacement: If the above troubleshooting fails, it is recommended to use spare parts of the same model for replacement testing to quickly locate the fault point.

Q4: When retrofitting old elevators, are there any special considerations when selecting Monarch display boards?
A4: Renovation projects need to focus on:
Installation size compatibility: Whether the opening size of the new display board matches the original board to avoid secondary processing
Function downgrade adaptation: Some old systems do not support a full-color TFT display, and you need to choose a compatible LCD or LED model.
Cable reuse assessment: Confirm whether the original communication cable specifications meet the transmission requirements of the new display board
