The HD28DSE is a powerful home cinema projector engineered in collaboration with DARBEEVision™. DARBEEVision’s Visual Presence technology was created by Paul DARBEE in the 1970’s and was pioneered using an unorthodox technique that involved “defocusing” one of two images, using a video synthesizer to invert the image, and then combining the defocused inverted image with the sharp image. The end result produced images with unrivaled separation in depth, amazing detail and image clarity that is simply striking.

The DARBEE Visual Presence™ enabled Optoma HD28DSE delivers an immersive experience in Xbox One and PS4 games, Blu-ray movies, HDTV programming, home videos and even vacation photos. The integrated DARBEEVision™ image enhancement technology utilizes neuro-biologic algorithms to achieve unprecedented detail in skin tones, textures, and reflective surfaces while delivering superior depth, object separation and automatic removal of unsightly artifacts. The end result is Xbox One and PS4 games, Blu-ray movies, HDTV programming, home videos, and photos that are simply mind-blowing and larger-than-life.

Breathtaking Clarity, Depth and Realism

Installing projectors on a table or pedestal can quickly become a frustrating experience as tilting the projector from various angles to reach the projection surface can result in trapezoidal images and the need to use keystone correction, which is also a frustrating experience. With Four Corner Adjustment the trapezoidal image can be quickly corrected by adjusting the corners of the image in or out, which simplifies installation and eliminates frustration.

The HD28DSE’s features the latest and greatest digital media interface with support for MHL v1.2. MHL v1.2 enabled HDMI ports allow MHL devices such Optoma’s HD Cast Pro, Roku’s Streaming Stick and Smart Phones to connect directly to the projector to playback music and video, view pictures and even share webpages and other user generated digital media content.

Some external audio/video devices today require USB power or external AC power to function properly. To satisfy this requirement, the HD28DSE includes a powered USB port that is great for powering devices such as Chromecast and FireTV media dongles, Optoma’s WHD200 Wireless HDMI System or any media device that requires USB power or AC power.

Many projectors require a new lamp every 4000-5000 hrs, but with an excellent cost to performance ratio, the HD28DSE will only require one lamp every 8000 hrs when the lamp mode is set to Bright+Dynamic.

Dynamic Black

This feature gives more depth to your image by smoothly adjusting the lamp output, based on the brightness information of each frame; to create a stunning high contrast ratio. Bright scenes appear crisp and clear, while dark scenes remain detailed with deep blacks and exceptional light and shade detail.

Integrated speaker

Complete your home entertainment experience with the convenience of a powerful built-in speaker. Built-in speakers provide exceptional sound quality and are easy to set up without the need for costly external speakers.

Horizontal keystone and Four corner adjustment

Adjust the keystone on the horizontal plane or individually wrap each corner of the image to create a perfectly square image. Ideal for uneven walls or where projector placement is awkward and needs to be installed at an angle.
