Optoma home multi-function projector, HD39HDR, has 1080P full HD resolution, and the brightness is increased to 4000 lumens. As a home projector, Optoma HD39HDR can cast a maximum screen of 300 inches. How's the review about it? Let's have a look.
Appearance
White has always been the dominant color for home projectors, and the Optoma HD39HDR is no exception. The streamlined case is a matte plastic that's slip-resistant and won't leave fingerprints. The body is very sturdy, and the overall stylish color can also be perfectly integrated with the home.
Since it is a home machine, a lightweight design is also essential. This projector has an ultra-thin and lightweight design, measures 316mm x 243.5 mm x 115mm, and weighs 2.5Kg. It is easy to move and does not take up too much space.
Height adjustment
The bottom of the projector adopts a 3+3 point design, of which the three short feet are special fulcrums for hoisting and fixing, and there are metal screw holes inside. Three long feet are support points, two of which can be adjusted in height, and the other two adjustable feet have rubber pads for non-slip shock absorption.
Lens and focus
The lens and focus ring of the Optoma HD39HDR projector are built-in, which not only protects the lens, but also makes the overall appearance smoother. The focusing knob on the upper part of the lens supports 1.3 times lens zoom and can project a 60-300-inch screen.
Heat dissipation
The Optoma HD39HDR projector adopts a large-area heat dissipation grille design on both sides of the projector, which ensures that it will not overheat when used for a long time. The powerful fan can ensure good heat dissipation while minimizing the accumulation of dust.
Ports
In terms of interfaces, Optoma HD39HDR projector is equipped with RS-232 control interface, AUDIO input/output interface, VGA signal input interface, 1 HDMI 1.4 interface, 1 HDMI 2.0 interface and USB interface. These rich interfaces allow the projector to connect to various entertainment devices, providing convenience for home entertainment.
Long life span
The Optoma HD39HDR projector has a projection lamp life of up to 10,000 hours in energy-saving mode, which greatly saves the post-maintenance cost of the product. In addition, the projector also has a built-in 10W high-quality speaker, which is very effective.
Remote control
The design of the remote control is relatively small, and the button feel is also commendable. The addition of the backlight function is very suitable for users to control in a dark environment.
Brightness
Brightness is what people care about most. How does this projector perform with 4000 lumens and a contrast ratio of 50,000:1? Let's take a look at the brightness effect of this projector.
Completely in dark
Turn on four indoor lights
The picture is very clear and vivid in a completely dark environment, and the color is slightly weakened when the light is turned on, but the overall picture is excellent. We also tested the Optoma HD39HDR projector with a TES136 illuminometer, and the peak brightness was 3896lm, which is about 97.4% of the official nominal brightness of 4000lm. Generally speaking, it is best if the peak brightness can be close to 95% of the nominal value or even exceed the nominal value.
Color
Color is the most critical factor in the performance of the projector screen. So how does the Optoma HD39HDR projector perform?
The Optoma HD39HDR projector uses the latest generation of high-end integrated image processors, and Brilliant Color II technology with a 6-segment color wheel. While improving the brightness of the picture, the color saturation is increased by strengthening the mid-tones, making the picture color more realistic and vivid.
From the screen shot, we can see that this projector increases color saturation by enhancing the mid-tones, making the color of the picture more realistic and vivid. The items in the picture above are brightly colored but not oversaturated, with natural transitions, clear distinctions, and no color overflow.
4K HDR video
Although this product is a 1080P projector, it supports 4K resolution signal input display and HDR Like function. Let's take a look at the performance of playing 4K HDR video.
We can see from the 4K HDR video screen shot that the picture is clearly layered and the transition is very natural. Whether it is the white clouds lingering on the top of Mount Fuji or the fireworks burning from the firewood, it all looks real and natural.
Noise
For a home projector, noise is a very critical factor, after all, no one wants to watch a movie in a noisy environment. In the living room with an ambient noise of 31 decibels, the noise value measured at a distance of 1 meter from the machine is 33.6 decibels, and the noise generated by the machine is hardly felt.
Summary
The Optoma HD39HDR projector excels in home use with its sleek and lightweight design, high brightness of 4,000 lumens, and high contrast ratio of 50,000:1. In addition, excellent dustproof performance, low noise and heat generation are also surprising. The outstanding configuration in all aspects allows this projector to easily meet the projection needs of users at home.
