Genuine DMD chip for Optoma projectors

This genuine OEM DMD/DLP chip replaces the imaging element in Optoma W311, DW326e and ML750ST projectors. It is supplied new and has been tested at least three times to verify a clear image with no dead pixels. The part restores full projection capability when the original chip has failed. Installers should confirm the exact model number before ordering.

Thermal and power characteristics

The chip operates within the projector's existing thermal design and draws power through the standard internal connector. No additional cooling or power modifications are required for normal use. Acoustic output remains unchanged because the component has no moving parts. The projector's original fan and heat-sink arrangement continues to manage temperature as designed.

Warranty and cosmetic notes

A 60 day warranty covers the component against defects. Product photos are illustrative only; the actual chip may show cosmetic marks, scratches or blemishes in areas not visible in the images. These surface imperfections do not affect imaging performance. No software, cables or mounting hardware are bundled with the chip.

Questions about this item

How do I install the DMD/DLP chip in my Optoma W311 projector, and what step is often missed?

Remove the optical block, detach the old chip from the heat sink, apply fresh thermal paste, seat the new chip squarely, then torque the spring screws evenly so pressure is uniform across the die.

What maintenance will this DMD/DLP chip need after installation?

No scheduled maintenance is required for the chip itself; keep the projector’s air filters clean and the cooling path unobstructed so the chip stays within its thermal limits.

What is the first limit that appears when the projector runs continuously with this chip?

The 60-day warranty period is the first defined limit; sustained operation beyond that relies on adequate cooling to prevent thermal stress on the DMD.
