Quiet beamer with good image quality. Unfortunately, without integrated loudspeaker.
last modified: 11.10.2019, 11:28
The Acer C200 does exactly what you would expect from a battery-powered projector of this size. Only an integrated loudspeaker is missing. The picture quality is fine and the brightness is also sufficient for darkened rooms. Due to the resolution of 854 x 480 pixels, you shouldn't expect a miracle in the sharpness of the picture. That's why the beamer is only suitable for presentations to a limited extent.
The Acer C200 Mini Beamer can also be used as a power bank to charge other devices.
The Acer C200 LED beamer with DLP technology looks high quality processed and stable. However, the case is susceptible to scratches. The projector weighs only 350 g and has a resolution of 854 x 480 pixels. It has three rubber feet that ensure that the beamer always stands securely and doesn't shake. In addition, there is a fold-out stand at the front. The C200 also has a tripod thread on the underside. Focusing is done manually via the focus wheel. This, however, is somewhat stiff. Operation is via the control panel on the upper side. All connections are located on the back of the device. The existing inputs and outputs are:
- Headphone output
The beamer has two projection modes: front and rear. One mode for ceiling projection is unfortunately not available. In addition, one of three display modes can be selected: Standard, Bright or Eco. The C200 also has vertical keystone correction up to +/- 40°.
Since the projector does not have an integrated speaker, the headphone output must be used for sound reproduction. According to the manufacturer, the battery life is 4.5 hours.
The Acer C200 Mini Beamer can also be used as a power bank for charging other devices. The USB port can provide a maximum charging current of 1A.
In order to measure the brightness of the Acer C200, I measured the illuminance at nine defined points with maximum brightness and a white test pattern. I used a lux meter for this. 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 55 lux and an area of 1.1 m² to 60.5 lumens. The brightness of 200 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, nothing can be seen.
In order to compare the image quality of the mini 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. Thereby, the image quality corresponds to what one expects from a beamer of this size. In a dark room, brightness and contrast are good enough to display dark images. The colors are very saturated. This can lead to an unnatural skin tone, especially when depicting people. Unfortunately, the C200 does not offer any adjustment options for the colors.
The color display also depends heavily on the display mode. The Eco mode is darker, but provides a more natural colour representation. The standard mode offers a good balance between brightness and color, while the bright mode has a distinct green tint and very unnatural colors.
Also in all modes there are color artifacts at transitions between black and white. These are expressed by coloured stripes.
Unfortunately, the beamer is not usable in daylight. Even with the maximum brightness setting, almost nothing can be seen. However, this is not to be expected differently with a battery-operated beamer of this size.
Another problem is the representation of font. Due to the resolution of 854 x 480 pixels, large fonts are still easy to read, but smaller font sizes are blurred. You should consider this if you want to use this beamer for presentations.
The C200 is operated via the control panel on the top and is very intuitive. The individual keys 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 10 steps.
Navigation through the menu could have been done a bit better. A relatively large number of keystrokes are necessary to change the desired option.
Another negative point is the focus wheel. The focusing itself works perfectly, but since the focus wheel is a bit stiff, the beamer has to be held with the other hand during focusing.
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 C200 reached a temperature of 48.3 °C. The temperature of the fan is the same as that of the C200.
The fan of the C200 is very quiet. At a distance of one meter I measured a volume of 34 dB and at a distance of 20 cm next to the fan the volume is 42 dB. As soon as there is sound in addition to the picture, the fan can no longer be heard.
