Optoma UHD51A — High-Contrast Short-Throw 4K Projector with Quiet Operation

Optoma UHD51A

Here’s the detailed Optoma UHD51A review. The projector features native UHD quality, HDR10 compatibility, enhanced color mode, versatile connections, and regulation mechanisms. This device creates a high-quality image on a short distance while preserving the sharp detail on the large screen as well.

The high zoom capacity and keystone regulation make up for various installation positions, while the size and weight factor might become an issue in tight spaces. The native sound is quite loud and distinct adding up to the high value of this middle-priced 4K projector.

Design

The Optoma UHD51A has a distinctive design that reminds of other Optoma models while retaining an individual look. The body is black, with the grilled front panel and sides and shiny top panel. The horizontal aluminum strip and the alike lens rim make an individual accent. The device is quite big (5.1-inch tall, 15.4-inch wide, and 11.1-inch deep) and heavy at 11.7 lbs requiring a sturdy mounting stand for the wall or ceiling installation.

The top panel contains the operational buttons and zoom and focus regulating dials (the latter can be hidden under the sliding panel). The backside houses the connection ports (HDMI, USB, VGA, mini-jack, etc.). The remote is a small black bar with the minimum buttons, which are quite tall and intuitive to use.

Features

As can be read in the Optoma UHD51A manual, the projector is equipped with DLP chipset and the 2,400-lumen lamp with the 4,000-15,000 hour resource. The color matrix is based on the DCI-P3 technology and supported by the 6x RGBRGB wheel producing over 1 billion colors. The device is fully compatible with HDR10 and implements the Rec.2020 format.

The resolution is the native 4K representing 8 million pixels simultaneously. The Ultra Detail and Dynamic Black technologies enable the contrast ratio of 500,000:1. The projector also supports the 3D video format.

The projector can create the 30 - 300-inch display at 3.4 - 26.4ft. It has the 1.3x manual and digital zoom and the vertical regulation of the lens and focus.

Connectivity is represented with two 2.1 HDMI ports, three USB type-A ports, the LAN input, audio input and output, the VGA port. The UHD51A is compatible with Alexa and Echo voice command devices.

The speakers produce the stereo sound at 10W. The inner fan noise is rated at 28 dB.

Performance

The variety of the picture modes brings flexibility and provides the optimal settings for the different conditions of use (environment light, content played, and consumption). The utmost clarity and color accuracy and saturation are provided in the Cinema mode while the Bright mode can bring some halo around the peaks in the HDR. Both SDR and HDR formats feature a lot of detail and well-textured shades.

The Optoma UHD51A projector is compatible with numerous devices and is easy to set up. The graphic interface is easy to navigate and informative. Hooking up the Alexa or Echo device, you can control the volume, power on and off, input switching, and USB media via the voice commands.

The sound quality is good, with the distinct stereo separation and clear dialogs. The volume can be adjusted quite high to fill the middle-sized room. The integrated fan works quietly becoming slightly louder in the heavy-load Bright and Cinema modes.
