Genuine DMD Chip for Vivitek Projectors

This OEM DMD/DLP chip is a direct replacement component for Vivitek D557W, DW868, D751ST and D755WT projectors. It restores the imaging engine when the original chip fails or degrades. Technicians and maintainers use it to return a projector to service without replacing the entire unit. The part is supplied new and has been tested extensively for clear projection.

Tested for Dead-Pixel-Free Imaging

Each chip undergoes at least three test cycles to verify a clear image with no dead pixels before it ships. The component mounts inside the projector's optical block, so installation requires disassembly and careful handling of the light engine. Because it is an OEM part, the mechanical and electrical interfaces match the factory design exactly. No adapters or firmware updates are needed.

Replaces a Failed Factory Chip

This component replaces the original DMD chip when it develops stuck mirrors or pixel defects that degrade picture quality. The upgrade is worth it when the projector chassis and optics remain sound but the image shows artefacts. It is not for users who need a different resolution or brightness level, nor for models outside the four listed series.

Questions about this item

Does the DMD chip for the D557W use a standard interface that limits resolution or refresh rate?

This is a genuine OEM DMD/DLP chip built for the D557W, DW868, D751ST and D755WT models; it replaces the original light-engine component directly with no separate interface standard to consider.

What physical space or mounting points are required to fit this chip inside the projector?

The chip is designed as a direct drop-in for the listed Vivitek projectors, matching the original DMD board dimensions and connector alignment exactly.

How is the DMD chip installed, and what step do people often get wrong?

Installation requires opening the optical block, removing the old DMD board and seating the replacement; the step most often missed is keeping the new chip’s window perfectly clean and static-free before closing the engine.
