If you’re looking for an affordable Full HD projector with quality 3D picture, accurate colors, and gaming opportunity, check this Optoma HD27 review. The projector can be used in the rooms with different amount of light or outdoors, supports wireless streaming and screen sharing via the MHL-compatible dongles, and features the enhanced 3D connectivity.
The connectivity is minimal; yet, it would serve well for the occasional movie, TV watching, or gaming. Integrated speakers are fine for this purpose, while the connectivity panel includes single audio out port.
The Optoma HD27 model has slotted front, back and side panels, multiple ventilation and speaker openings. The device is 11.73-inch wide, 9-inch deep, and 3.7-inch tall, and weighs 5.3lbs. It rests on five feet, three of which are adjustable.
The lens is installed in slightly off-center to the left and is placed within a ribbed funnel. The edge of the funnel is gear-like and performs the manual focus adjustment function. On top of the projector, there’s the zoom control and the navigation keypad with the LED indicators. The connections of the Optoma HD27 projector are located on the back and comprise of HDMI, Vesa 3D, audio output, USB power/service, and 12V trigger ports.
The Optoma technology HD27 is based on a single DMD chip DLP and supported by the 3,200-lumen lamp. The lamp life varies between 5,000 (Bright mode) and 8,000 (Dynamic mode). The resolution is the native Full HD, the color range includes 1.07 billion colors.
The Brilliant Color technology and the Reference mode provide compliance with the Rec.709 color mapping. Compatible with sRGB content. The contrast produced by this device makes 25,000:1. 3D content is produced at a 144Hz refresh rate.
The throw distance of the projector makes 3.2 – 32.80ft, the screen size ranges from 30 to 305 inches. The adjustment options include the vertical keystone correction and 1.1x zoom.
Connections include two 1.4 HDMI ports, one of which has the MHL protocol. The Optoma technology HD27 is also notable for the 3D Sync port and multifunctional USB type-A. Other connections make the audio out port and the 12V trigger.
The input lag of the device makes 33ms. The built-in speakers produce the mono signal at 10W. The projector’s noise is estimated at 26 dB.
The brightness declared in the Optoma HD27 manual corresponds with the actual projector’s operation. It provides well-saturated colors and high contrast both in dark, semi-lit and even well-lit rooms, with a slight difference. The latter, however, can be regulated through the flexible options of color adjustment.
Still, the brightness isn’t entirely even over the screen, which sometimes causes the halo effect around the peaks. The color balance is sufficient in all the preset modes of the projector (these make the Cinema, Film, Vivid, Game, Reference, 3D, ISF (Day, Night and 3D) and User modes). The saturation of whites changes with the amendments to other color parameters producing a consistent image in most of the cases. The blacks are the deepest in the Cinema mode, while the brightest colors are available in the Vivid mode.
The small input lag makes this model a good fit for gaming and PC monitor. The motion is pictured well, without noticeable judder, while some color transitions might be too abrupt. The sound is loud and has some bass while the projector’s noise is hardly noticeable at the small load.
