Enjoy movies and video games in Full HD resolution with the Optoma HD28HDR Full HD DLP Projector. It has a native resolution of 1920 x 1080 to display high-resolution images and video, and a 50,000:1 dynamic contrast ratio to enhance the clarity of dark areas of images. The 3600 lumens of brightness overcomes ambient light in many home settings, and features like Enhanced Gaming Mode help enhance your experience while gaming. When paired with compatible 3D glasses, this projector also supports various 3D formats.
The HD28HDR has two HDMI inputs for connecting your cable/satellite box, Blu-ray player, or gaming system. A 3-watt speaker is built-in for audio playback, as is an 1/8″ audio output to connect to your external speaker system. The projector includes an IR remote control for added convenience.
4K UHD & HDR10 Input Compatible
HDMI 2.0 with HDCP 2.2 connectivity enables compatibility with 4K UHD video sources, and HDR10 support helps enhance color quality with brighter whites and darker black levels.
Designed for Gaming
Computer and console gamers can take advantage of the 120 Hz refresh rate for smooth, virtually blur-free visuals. Enhanced Gaming Mode reduces input lag down to 8.4 ms at 1080p 120 Hz for nearly lag-free input response.
Vertical keystone correction and 1.1x zoom help provide flexible installation options.
Digital Light Processing (DLP) Technology
DLP technology is designed to provide high contrast, fast response time, good pixel structure, and virtually no color degradation.
High dynamic range (HDR) technology helps deliver bright whites with deep black levels. Four selectable picture modes, Normal, Bright, Detail, and Film, are available. The HD28HDR also meets the Rec.709 color standard to help produce accurate color.
Display 3D content from almost any compatible source, including 3D Blu-ray players, broadcast, and game consoles. 144 Hz rapid-refresh rate is supported for smooth, flicker-free images. Compatible 3D glasses are required and sold separately.
Full HD Resolution
1080p resolution renders sharp, detailed images from HD content without downscaling or compression, making the HD28HDR well-suited for movies, TV shows, and gaming.
Dynamic Black Technology
This feature is designed to provide more depth to your image by smoothly adjusting the lamp output to augment the contrast ratio. This helps bright scenes appear crisp and clear while keeping dark scenes detailed with deep blacks and light and shade detail.
ISF modes allow you to save your calibrated day and night mode settings for your preferred viewing experience.
Connect your compatible smartphone or tablet via MHL to view presentations, stream videos, and share photos from your device.
Direct Power On
This feature aids installations that rely on power-on timers by allowing the projector to be turned on directly from the power source. The sleep timer can also be used to turn the projector off after a set time.
