In dark rooms, the Optoma HD143X convinces with its high resolution, its razor-sharp image, and the realistic colours. However, the low brightness is disappointing. If a room is not dark, dark parts of a picture or film are difficult to recognize. But the operation with a focus wheel, remote control and buttons is very easy.
The Optoma HD143X beamer with DLP technology looks high quality processed and stable. It weighs 2.8 kg and has a full HD resolution of 1920 × 1080 pixels. It has four rubber feet. The HD143X also has a tripod thread on the underside. Focusing is done manually with the focus wheel. The 8 buttons on the top or an extensive remote control are used for the operation. All connectors are located on the back of the unit. The available inputs and outputs are:
- 2 x HDMI
- Headphone output
- 12 V current output (e.g. for electric screens)
- 3D SYNC input
The projector has four projection modes: front, rear, ceiling front, and ceiling rear. In addition, one of three display modes can be selected: Standard, Light or Eco. The HD143X also has vertical keystone correction up to +/- 40°.
The HD143X has an integrated 10W speaker for sound reproduction.
The Optoma projector has a 12 V trigger which can be used, for example, to power an electrically operated screen.
In order to determine the brightness of the Optoma HD143X, I measured the illuminance at nine defined points on maximum level and white test pattern. For this, I used a lux meter. The mean value of these measurements and the projection area can then be used to calculate the luminous flux in lumens. With this device, the luminous flux results with an average illuminance of 225 lux and an area of 0.725 m² to 165 lumens. The brightness of 3000 lumens specified by the manufacturer could therefore not be confirmed. In well-darkened rooms, this brightness is sufficient for the reproduction of films, but in daylight dark pictures are difficult to recognize.
In order to compare the image quality of the beamers in our test, we have developed a test image. This image can be used to evaluate brightness, contrast and colour representation.
First, I tested the image in a darkened room. It is razor-sharp and has a good resolution. In a dark room, brightness and contrast are good enough to display dark images. The colors are reproduced very realistically and naturally.
The colour reproduction also depends strongly on the display mode. The Eco mode is much darker than the Standard mode. I couldn't tell the difference between these two modes in the hue of the image. In bright mode, however, the image has a very strong green tint.
Unfortunately, the beamer is not very convincing in daylight. Even at maximum brightness, dark images are difficult to recognize. This is somewhat disappointing for a beamer in this price range.
Due to the high resolution, the display of font does not pose a problem for this beamer. It is suitable for presentations in this respect.
The HD143X is operated via a very intuitive remote control. The buttons on the top side can also be used for easy adjustment and commissioning. The individual buttons react without any problems. The menu can be used to set the display mode, projection mode, and keystone correction. In addition, brightness and contrast can be adjusted in 100 steps.
With the aid of a wheel for zoom and a wheel for focus, the beamer can be easily adjusted to focus at a distance of 1-10 m.
I measured the heating of the beamer during operation with our thermal imaging camera directly at the opening of the fan. In our tests, the HD143X reached a temperature of up to 68 °C.
Volume and sound quality
The fan of the HD143X is very quiet. At a distance of one meter, I measured a volume of 37 dB and at a distance of 20 cm next to the fan, the volume is 48 dB. As soon as there is sound in addition to the picture, the fan can no longer be heard.
For normal use in the living room or for a small presentation, the volume of the speakers is fine. For a larger room, it is better to connect more powerful speakers.
The beamer has a 3D function, for which you need special glasses. We didn't include this function in this test.
We have evaluated about 80 customer reviews on the Internet. In summary, it can be said that about 70 percent of buyers are satisfied (4 stars) or even very satisfied (5 stars). Partially (2 stars) or completely dissatisfied are about 20 percent of the users. The average score at the time of the evaluation was 3.8 out of 5 stars.
The following points were positively noted:
- Image quality
- Low noise level
The following points were noted negatively:
- Zoom range could be larger
