Enjoy bright images and high dynamic contrast at short throw distances with the Optoma EH412ST 4000-Lumen Full HD Short-Throw DLP Projector. Its native 1920 x 1080 resolution displays data and images clearly at various viewing distances, while its 50,000:1 dynamic contrast ratio helps enhance detail in dark images. Its 0.5:1 throw ratio allows you to place the projector near the front of the room, making it well suited for large-screen presentations in small rooms.

The EH412ST features VGA and two HDMI inputs, one of which is MHL-compatible for sharing media from your compatible smart device. A USB port provides power for compatible HDMI streaming adapters. An IR remote and carrying case are included as an added convenience.

DLP Technology

Digital Light Processing (DLP) technology is designed to provide digital projection with higher contrast, faster response time, good pixel structure, and virtually no color degradation.

Rec.709 Color Reproduction

The EH412ST can reproduce the Rec.709 color gamut to help ensure cinematic color as the director intended and saturated colors for gaming and animated content.

Direct Power On

Turn on the projector directly from the power source. This is helpful in installations that rely on power-on timers. The sleep timer can be used to turn the projector off after a set time.

Dynamic Black Technology

Dynamic Black is designed to provide more depth to images by smoothly adjusting the lamp output to enhance the contrast ratio, making bright scenes appear crisper and clearer, while retaining detail in dark scenes with deep blacks.

MHL Connectivity

Connect your compatible smartphone or tablet to the projector via MHL, allowing you to view presentations, documents, streamed videos, and photos.

Integrated Speaker

The built-in speaker mitigates the need for an external speaker system, helping to simplify your setup.

Long Lamp Life

The lamp can last up to 15,000 hours in Dynamic Mode, reducing the number of lamp changes.

RS-232 Control

Control the projector using HEX or ASCII commands via your RS-232 cable.

USB Power

Power and charge your USB devices with the USB power port. It delivers up to 1 amp, making it well suited for use with compatible HDMI streaming devices.

Signal Power On

The projector can power on when it receives a signal through the HDMI input, ensuring the projector is turned on at the same time as the source device.

Crestron RoomView with Network Control

Crestron software provides a custom configurable interface to monitor, manage, and control every connected device in every room remotely from virtually any computer. Via a master computer, you can manage up to 250 projectors at the same time, control and alter settings using a web browser page (including OSD menu control), and set up email alerts for warning messages, making the EH412ST well suited for use in large installations in both educational and business environments.
