Restore Perfection: 6.8 Inch 9K Mono LCD Replacement Screen
The 6.8 Inch 9K Mono LCD brings the highest level of detail to consumer 3D printing. With a pixel density defined by its 18×18 micron pixel pitch, this screen eliminates the “stair-stepping” effect on curved surfaces, making it essential for printing jewelry casting patterns and high-fidelity gaming miniatures.
Perfect Match for Mars 4 Series
Engineered with an active area of 153.36 x 77.76 mm, this display offers a drop-in fit for:
- Elegoo Mars 4 9K
- Elegoo Mars 4 Ultra
It utilizes the standard MIPI 50-Pin connector, ensuring plug-and-play compatibility with the original mainboard without requiring firmware hacks.
Optimized for MSLA Performance
Unlike generic LCDs, this 3D printer-specific panel features:
- High UV Transmittance: Optimized for 405nm UV light sources, allowing for rapid exposure times while blocking light in black areas with a 300:1 contrast ratio.
- Durable Design: Rated for operation up to 70°C, it withstands the heat generated by COB LED light sources during extended print sessions.

Engineering FAQ
Q: Is this screen compatible with the Elegoo Mars 4 Ultra?
A: Yes. The specifications (Resolution 8520×4320, Active Area 153.36×77.76mm, and Interface) match the original screen used in the Elegoo Mars 4 Ultra and Mars 4 9K perfectly. Please check your original FPC cable shape to doubly confirm.
Q: What does “9K Resolution” mean for my prints?
A: 9K refers to the 8520×4320 pixel count. On a 6.8-inch screen, this results in an incredibly small pixel size of 18 microns. This allows you to print models with sharper details and smoother surfaces compared to older 4K (35um) or 2K (50um) printers.
Q: Do I need to update my printer’s firmware?
A: Generally, if you are replacing the screen with the exact same resolution (9K to 9K), no firmware update is needed. However, if you are upgrading a different printer to this screen, you will need a compatible driver board and firmware configuration.
Q: Does it come with a screen protector?
A: The LCD module includes the polarizing film pre-installed. We strongly recommend adding a separate FEP or tempered glass screen protector (sold separately) during installation to protect the screen from resin spills.
