What This Guide Covers
This tutorial explains how to:
- Upgrade the Orange 4K Color firmware to Orange 4K Mono firmware
- Prepare the USB drive correctly
- Complete the firmware update safely
- Understand exposure parameter adjustments after the LCD replacement
- Learn important precautions before replacing the LCD screen
This guide preserves the original operation sequence and official instructions.
Quick Answer
How do you upgrade the Orange 4K Color Version to Orange 4K Mono?
- Download and unzip the correct firmware package.
- Copy the firmware file to the root directory of a USB drive.
- Turn off the Orange 4K machine.
- Insert the USB drive into the printer.
- Turn the printer back on.
- Wait for the firmware update to complete automatically.
- The machine will reboot and become ready for printing.
After replacing the LCD screen, exposure settings must be adjusted because UV intensity increases significantly with the 4K Mono LCD.
Why This Process Matters
The Orange 4K Mono uses a 5.5-inch monochrome LCD screen with a resolution of 6480 × 3840 at 10.5/31.5µm and features a dual Z-axis design for more stable printing.
Compared with a color LCD:
- Monochrome LCDs allow higher UV light transmission
- Resin curing becomes faster
- Print details become sharper
- Screen lifespan is generally longer
- Printing efficiency improves significantly
Because UV intensity increases after the upgrade, exposure settings must be adjusted properly to avoid overexposure during printing.
Before You Start
Requirements
Prepare the following before starting the upgrade:

LCD Screen Replacement Guidance
After replacing the 4K Color LCD with the 4K Mono LCD, UV intensity increases significantly.
Because of this:
- Exposure parameters should be adjusted accordingly.
- Parameters can be modified through the printer touch screen.
- Parameters of a job file (
*.lgs4k) can also be changed on a computer using LongerWare.
Follow official machine specifications or instructions.
