Optoma HD28e

Optoma’s HD28e is a Full HD DLP projector weighing under 2.5 kg. It delivers 3,800 lumens of brightness and several display modes tailored to different uses, from movie watching to gaming sessions and sports broadcasts. Input lag is 16 milliseconds.

A concentrate of DLP technology in an ultra-compact form factor

The HD28e features a white chassis with clean lines, measuring 316 × 244 × 108 mm and weighing 2.5 kg. The control panel on the top provides direct access to key functions, and the projection lens is protected by a removable cap that makes focusing easier.

The remote control is backlit for easy menu navigation in the dark. Button LEDs are subtle, and operating noise is 25 dB in standard mode and 27 dB at maximum.

Latest-generation DLP architecture

At the heart of the HD28e beats DLP (Digital Light Processing) technology paired with Texas Instruments’ latest 1080p DMD chip and the DDP4422 graphics processor. This technical combination produces remarkably sharp images with a native Full HD resolution of 1920 x 1080 pixels. The six-segment RYGCWB (Red, Yellow, Green, Cyan, White, Blue) color wheel significantly enriches the color spectrum compared with traditional three-color solutions.

The optical system includes a 1.1x manual zoom with a focal length ranging from 15.59 to 17.14 mm, offering a throw ratio of 1.47:1 to 1.62:1. This setup lets you project a 100-inch image (254 cm diagonal) from a distance between 3.7 and 4.1 meters, fitting most home layouts. Vertical keystone correction of ±40° greatly simplifies installation by compensating for geometric distortion when the projector isn’t perfectly aligned with the screen.

Luminous performance that transforms your living room

With 3,800 ANSI lumens in Bright mode, the HD28e clearly stands out in its price range. This exceptional light output delivers a quality picture even during the day with the curtains open, turning the family living room into a truly versatile projection space. Eco mode reduces brightness by about 33% while significantly extending lamp life and lowering noise.

The native contrast ratio of 30,000:1 ensures impressive image depth with truly deep blacks and brilliant whites. Dynamic Black further enhances contrast by automatically adjusting lamp power according to the displayed content. Dark scenes retain all their subtle details, while bright sequences remain perfectly readable without overexposure.

Rec.709-certified color reproduction

The HD28e strictly adheres to the Rec.709 standard, the international high-definition television standard set by the International Telecommunication Union. This compliance guarantees color reproduction faithful to the director’s intent—crucial for discerning cinephiles. The projector covers the entire sRGB color space, ensuring optimal color accuracy for both cinematic content and professional presentations.

Optoma’s Amazing Colour technology lets you switch between different color profiles depending on preferences and content. Skin tones appear natural and nuanced, landscape greens pop vividly, and skies retain subtle gradations with no visible banding. This chromatic versatility is especially welcome when switching from a desaturated drama to a brightly colored animated film.

Responsiveness designed for modern gaming

The HD28e shines in gaming thanks to its Enhanced Gaming mode, which slashes input lag to just 16 milliseconds at 1080p 60 Hz. This exemplary responsiveness, comparable to top gaming monitors, ensures perfect sync between controls and display—crucial for competitive shooters or demanding racing titles. The projector can even drop to 8.4 milliseconds at 1080p 120 Hz on compatible setups, rivaling the best gaming screens.

The Game mode developed specifically by Optoma’s color lab engineers significantly improves visibility in dark areas. After extensive simulations under various ambient lighting conditions, this mode intelligently lifts shadow detail without blowing out highlights, helping players more easily spot hidden elements or lurking opponents. This Shadow Boost function is particularly useful in horror games or tactical titles where every detail counts.

Native 3D compatibility for total immersion

The HD28e natively supports 3D content from all compatible sources: Blu-ray 3D players, latest-generation consoles, and stereoscopic TV broadcasts. The system accepts Side-by-Side, Frame Packing, and Over-Under formats at refresh rates up to 144 Hz, delivering smooth, flicker-free 3D images. A dedicated 3D display mode automatically optimizes brightness and contrast when receiving a stereoscopic signal, compensating for the inherent brightness loss when viewing with active glasses.

Connectivity and smart features

The HD28e focuses on essentials with a 3D-compatible HDMI 1.4a input that accepts all signals up to 1080p at 120 Hz. This single digital video connection simplifies installation while ensuring optimal image quality without analog conversion. The powered USB-A port (5V/1.5A) is a major plus, allowing you to power streaming dongles like Google Chromecast or Amazon Fire TV Stick directly, without an extra power supply.

The 3.5 mm mini-jack audio output lets you connect an external audio system for sound that matches the picture quality. The built-in 5-watt speaker, while modest, still provides a satisfactory stopgap audio solution for mobile use or when a dedicated audio system isn’t available. Sound quality is adequate for dialogue and simple effects, though bass naturally lacks depth.

Automated functions and ISF modes

HDMI Link (CEC) automatically synchronizes the projector’s power on/off with compatible connected devices. No more juggling multiple remotes: turning on your set-top box or game console automatically wakes the HD28e, greatly simplifying daily use. Power management features include auto power off after a user-defined idle period and Quick Resume for instant restart after accidental shutdown.

ISF (Imaging Science Foundation) modes let you store custom calibrations for day and night, ensuring optimal picture quality in any lighting. Native 24p support preserves the original cinematic cadence of films, avoiding stutter and judder for an authentic theater experience. Wall color compensation offers six presets (blackboard, light yellow, light green, light blue, pink, and gray) for projecting onto colored surfaces while maintaining acceptable color reproduction.

Durability and cost of ownership

The HD28e’s 240-watt UHP lamp boasts impressive lifespans: 4,000 hours in Bright mode, 10,000 hours in Eco, and up to 15,000 hours in Dynamic. Based on 4 hours of daily use, this exceptional longevity means over 10 years of use in Dynamic mode before a lamp replacement. Eco+ intelligently adjusts brightness according to displayed content, further extending lifespan while reducing power consumption.

Energy consumption is well controlled at a maximum of 295 watts at full power and only 205 watts in Eco mode. Standby draws just 0.5 watt, meeting stringent environmental standards. The optimized cooling system ensures efficient heat dissipation while keeping noise low, guaranteeing long-term reliability of electronic components.
