To make sure this projector is the right fit for you room

The InFocus IN81 is a Full-HD 1080p DLP digital home cinema projector. The IN81 utilizes the DarkChip2 DLP chipset by Texas Instruments, technology which delivers deep black levels, pure whites, and subtle grayscale details. Also, the native 3000:1 contrast can be boosted to a maximum 10000:1 by activating the onboard iris.

Bright enough to deliver film-standard, D6500K color accuracy, even with ambient light or daytime viewing. Producing video optimised brightness up to 1400 Max ANSI lumens this projector is spectacular and offers the flexibility to reduce brightness to improve black level performance in a dedicated home theater without dimming the picture.

Future-proof thanks to onboard HDMI 1.3 inputs with Deep Color support. This new HDMI standard can display up to 1.07 billion colors for a smooth picture without color band artifacts. The InFocus IN81 also hosts comprehensive connectivity & I/O, including DVI, and PC input, screen triggers, RS232, and an IR repeater input. (Deep Color requires HDMI 1.3 compatible media player & source material.)

True video magic projected by the IN81 is thanks in-part to Pixelworks DNX 10-bit video processing. This is the same outstanding processing, de-interlacing, and scaling performance as the award-winning InFocus Play Big IN7x series. The IN81 hosts unrivaled built-in scaling support at this price-point for 2.35:1 aspect ratio, for a true Cinemascope/widescreen without an external scaler (requires anamorphic lens, available separately).
