Optoma HD81 Projector

Filed under: Projectors

Optoma announced the shipping of its HD81 home theater projection system. The HD81 is a distinctive two-piece projection system that includes a native 1080p DLP projector and a video enhancement processor. The system features the DLP DarkChip3 DMD chipset and BrilliantColor technology, along with the video enhancement processor.

If the home does not have a true 1080p source, the HD81's processor will scale the source to the native resolution complete with motion adaptive HD/SD de-interlacing.

The HD81's video enhancement processor delivers an advanced three-stage process flow (decoding, image enhancement and color reproduction enhancement) that offers personalized adjustment settings at each stage.

[IMGP4376] This projection system features an active 16-step, auto-Iris function that boosts the contrast ratio up to 10,000:1. There is also a 10-bit color per channel color processor and a 4x 7-segment color wheel which virtually eliminates any rainbow effects (and though I'm sensitive to RBEs I didn't pereceive anything during normal viewing of several very action-intensive scenes.)

With its new industrial design, the HD81 lowers the noise level usually associated with other typical home theater projectors. The patent pending tunnel cooling system is designed for near-silent operation with minimal light leakage.

The two-piece design of the HD81 eliminates the need for multiple cables; all that is needed for the projector to be connected is a single HDMI video cable and a single control cable. With the image enhancement box's extensive inputs, there are more than enough connections to up-convert sources to 1080p for optimal viewing.

The Optoma HD81 home theater projection system is available now for an estimated street price of $6,999 through authorized Optoma dealers.
