Best 3D projector
More and more people would like to enjoy films of excellent quality from the home sofa. The advantages compared to the cinema visit are obvious: the apartment no longer needs to be left, the entrance is saved, the view is optimal and with a weak bladder the film can be stopped briefly. Home is simply the most beautiful. This makes the home cinema more and more professional and the cinema feel for the home has always improved. With 3D beamers and enough space in the living room, film fans and gamers can get their money’s worth. In our 3D Projector Comparison 2017 you can find your personal 3D-Beamer comparison winner. We explain what is important when you want to buy a 3D projector.
1. What is a 3D projector?
Most 3D projectors are hardly different from conventional projectors, but they can also display 3D movies in HD or Full HD. As three-dimensional film enjoyment is becoming more and more popular in the living room, more and more projectors are able to reproduce films and videos in 3D. In the past, the name “Beamer 3D ready” had to be taken into account. In the meantime, all projectors, who are able to display three-dimensional content, use the “full 3D technology”. The projectors can play 3D content directly, while a 3D signal transmitter has to be added to old “3D ready” -bamers. 3D projectors are not more expensive than conventional projectors with high resolution; Among the best 3D projectors, DLP and LCD projectors are distinguished, since only a few LED projectors offer 3D technology. For the most part, 3D-beamers are high-performance devices, whereas mini-projectors or short-range projectors are generally not able to play 3D movies.
Purchase Criteria for 3D Beamer: You have to pay attention to this
3.1. 3D technology
Active shutter technology requires special 3D shutter glasses.
Most projectors use the so-called Active Shutter Technology to display three-dimensional films. In order for the projectors to make 3D films visible, special shutter glasses are required, which, like LCD-beamers, use liquid crystals and can be electronically intermittent and impermeable. Alternately, one eye is darkened, while two images are displayed side by side with the beamer at the same time. Through the spectacles, the images are superimposed, or synchronously only the appropriate image is passed to the corresponding eye, whereby the 3D effect arises. People with visual impairments might have problems with the 3D effect, spectacle wearers can usually wear the glasses over normal glasses.
In addition to the active variant, there is also a passive 3D technology. If the 3D-Beamer is passive, a polarization technique is used, in which two projector lamps simultaneously throw the picture on the wall. Unlike the active shutter glasses, so-called polar eyeglasses are used to make 3D beam polarization visible. This technology is especially widespread in 3D TVs. The spectacles are designed to transmit only horizontally polarized light on one side and only vertically polarized light on the other side. Because the glasses do not need electricity and do not have to be recharged, passive 3D technology is used. Both versions are well suited for the home cinema. Active Shutter glasses have been used in recent years. Of course, you can use the 3D beamer without glasses as well and look in 2D movies.
If you want to have a sharp picture, you have to look at the resolution of the home cinema beamer. If the 3D beamer is Full HD capable, a projector resolution of 1,920 x 1,080 pixels is required. Few affordable models are capable of 3D beamer 4K capable; This requires a fourfold HD resolution of 4,096 x 2,160 pixels. The beamer, however, should have at least one resolution in HD quality, everything else is no longer up-to-date. If you want to spend a lot of money on a home cinema projector, you should ensure that the beamer can play Full HD and 3D movies.
The lumen number describes the brightness with which the image of the projector is thrown onto the screen. For example, a 40 watt light bulb has 430 ANSI lumens. The higher the lumen value of a projector, the better you can use it during the day and in bright rooms. A low number of lumens means you have to darken the rooms a little bit, in order to be able to watch the 3D beamer and full HD movies.
Playful Strahlemann: The console can also be connected to the 3D beamer.
The contrast stands for the maximum brightness difference between black and white colors. The higher the contrast, the sharper the image and the more saturated the colors are displayed. In particular, home cinema projectors should have a high contrast value, so that the black and white tones come out realistically. In daylight, however, the contrast plays a subordinate role, here the brightness is of decisive importance for the picture quality. For a contrast ratio of 1,000: 1, the lightest point is one thousand times brighter than the darkest point. A 3D beamer should be able to display at least a contrast of 10,000: 1.
3.5. Image diagonal
Depending on how much space you have available and how you plan to use the projector, you should pay attention to the minimum and maximum image diagonal. As with flat-screen televisions, tablets or smartphones, the image diagonal is expressed in inches (“). Depending on how big your projection screen or beamer screen is, you should select the beamer. For the conversion of inches in cm there are many customs computers in the Internet. An inch is 2.54 cm – on average the 2.5-face value of the inch can be used to indicate the image diagonal in the metric system in cm.
The connection possibilities are as varied as the projectors. As a rule, however, the most important components of the home cinema can be connected. The models from our 3D Beamer comparison are equipped with one or more HDMI connectors that allow you to connect computers and laptops. Also for the connection of consoles the Beamer should be HDMI-capable. A VGA connection guarantees contact with a TV, should it have no connection for an HDMI cable. With a USB port, movies, presentations and photos can be thrown directly from a USB stick via the beamer to the wall or other players, such as iPods or MP3 players with the 3D beamer. In addition, many devices have an MHL connector. The abbreviation stands for “Mobile High-Definition Link” and ensures – as the English name already suggests – for a high-quality connection between beamer and smartphone or tablet.
4. Care and cleaning tips
Beamer are particularly sensitive companion, the correct projector care is therefore important, so that you are happy with your 3D beamer for a long time. Make sure that the beamer is in an airy place, so that no heat builds up. There should be some space around the ventilation slots, so that the ventilation of the projector works well. Beamer are also sensitive to smoke from cigarettes or other sources because the electronics inside can stick.
Most projectors are neither equipped for short operations under 15 minutes nor for a continuous operation over 6 hours. If you always find the right medium, the projector will last a long time in high quality. If you turn off the beamer after use, do not disconnect the unit immediately. As a rule, the projectors require a cooling time, which can vary between one and five minutes, depending on the model. If the room is dark, it is worth to use the eco mode of the projector. This mode not only saves electricity, but also protects the sensitive lamp, which can quickly wear out.
If you want to clean your projector, this is not a problem for the laity in most cases. The air filters can be simply removed without tools and can be cleaned from dust. In the case of heavy soiling or dust, the air filters can be removed, rinsed with detergent and reused after drying. The cleaning of the beamer with a vacuum cleaner simply works with the suction cup at the ventilation shafts of the projector and frees the projector from the annoying dust, which can lead to a strong noise. If the lens is dirty, you can use microfiber or eyeglass cleaning cloths to clean the beamer lens so that no coarse scratches will damage the projected image.
5. 3D Beamer
The Stiftung Warentest has not yet carried out a 3D beamer test. In a normal Beamer test in issue 06/2014, the Foundation has also tested a few 3D projectors: a Panasonic Beamer, followed by a BenQ projector, an Epson device and an Acer Beamer. Not examined were LED beamer, mini-beamer and short-term beamer. The Stiftung Warentest has compared the quality of the examined projectors with flat-screen televisions and comes to the conclusion: The picture of the projector is larger, but in terms of resolution and image quality, there are hardly any differences. Whether a beamer or a TV is better suited for the home cinema depends on how much space the user has available.
6. Questions and Answers about 3D Beamer
6.1. Which 3D projector for home theater systems is best?
Home cinema 3D beamer
3D projectors are made for use in home cinema. By the usually high quality and high-quality technology are most 3D Beamer home cinema-capable. Cheap 3D beamer are usually less good for the home cinema, because often compromises in the picture quality have to be made. For the home cinema it is worth to pay attention to good brightness, a strong contrast, a high resolution and a low noise level, so that in the living room real 3D cinema feeling can arise.
6.2. What 3D glasses are the right ones?
Even a 3D beamer comparison winner can beam such high-quality three-dimensional images to the wall, if the right glasses are not available. The models from our 3D projector comparison use the so-called shutter technology, so the 3D glasses should support this technology. In certain circumstances, only special glasses are compatible with the beamer, eg an Acer 3D projector lens only fits an Acer 3D projector. Many spectacles also specify the projector type (DLP or LCD).
6.3. Which screen is required for 3D projectors?
If you want to buy a 3D beamer, make sure you have the right projection surface for your new 3D projector. In addition to a smooth wall, special beamer screens are ideal for this. On most products, movies of all kinds can be played, whether in 3D or Full HD. The quality is usually better than on the wall, since hardly light is swallowed, but is evenly thrown back.
