Area of application: for What you need the projector?
What criteria are most important depends on the planned use of the projector. Especially for two areas of application of projector is popular and moves depending on the application, various functions in the focus:
- Use as a home theater: Here resolution, HDCP compatibility, 3D capability, operating volume and contrast ratio are in the foreground.
- Use for presentations and demonstration purposes: A special focus is on light strength, the ability to ceiling-mount, Video - and media connections, and in the case of portable devices, of course, the weight.
The right projector?
1. A projector as a home cinema
Home cinemas are often placed in smaller spaces with little light. Dynamic, broad-band sound, as well as a sharp and contrast-rich image is more important than many connections.
- Resolution: For movies in the living room has a HD resolution of 1920 x 1080 Pixel absolute Must pleasure. In the case of many projectors, this resolution is identified by the inscription "1080p".
- Connections: VGA is in principle to this resolution, able to display Blu-ray movies, however, is a digital, HDCP-enabled connection. Therefore, the projector needs an HDMI port or an HDCP-enabled DVI-I/ DVI-D port. Both connection types, as well as the HDCP copy protection we explain in this article. With the right adapters you can use the projector but also to retrofit, as we can see in the image gallery show.
- Additional Features: projector manufacturer's mark 3D-capable projector usually by the addition of "DLP 3D, DLP 3D Ready or Full-HD-3D-projector". Pay attention to this information, if you insist on 3D.
- Volume: For small spaces, like the living room, is a quieter projector is important. The noise level should be as low as possible, so that in quiet scenes, no noise emanates noise from the projector, preferably under 40dB. Let the figures fool you: indicate the noise level in ECO-Mode, can you beat 6 to 8dB on it, because in the movie the projector roars a little louder. Tip: values greater than 1 Sone are comparable with 40dB or more, so it is usually too loud.
- Sound: Internal speakers are not sufficient for a rich, cinema sound mostly: they provide neither the spectral bandwidth, the spatial sound, the Dolby Digital or DTS Sound promise.
- Contrast: the sharp contrasts of deep Black to bright White map, you should have your home theater projectors, at least a contrast ratio of 10,000:1
- Luminous intensity: As for the cinema-atmosphere in a darkened room, the brightness not quite as important criterion for home cinema projectors. From about 500 lumens, you are on the safe side.
- Tip: The CHIP-best list of home cinema projector gives you a good Overview of the various home theater projectors and other features, such as energy efficiency and subjective image quality.

2. Beamer for presentations
Whether for Meetings, conferences, or meetings - Beamer for presentations to be used in the rule, bright, large rooms, and with various devices. This you should note:
- Luminous intensity: high brightness ensures a bright environment for good contrasts. The brightness is specified in "ANSI lumens". From about 2000 ANSI lumens, the projector can be used easily in the daylight.
- Installation: keep in mind before buying, if your projector be ceiling mounted or would prefer transport to be profitable. The ability to ceiling-mount, unfortunately, is not given in any projector, because here is the bracket and harness are missing correction. Portable projector should weigh under 3kg and ideally have internal speakers.
- Connections: Since the projector is to be connected to different Computer, there is a wide variety of connections makes sense. The most widely used VGA, DVI and DHMI on computers as well as mini Display and Thunderbolt for MAC. Caution: Sometimes the 15-pin VGA is characterized connection as "D-Sub" a difference but there is no. Cameras often have a Composite output, the newer analog devices with a component output (YUV or YPbPr). In our pictures gallery learn more about the connections.
- Sound: TRS and RCA input are only useful if the projector is connected to a Sound system or the projector has its own speakers. The internal speakers are not sufficient, however, in General, for music playback, or the sound of a medium to large room.
- Extras: Many projectors have USB or SD card Slots. So presentations can be without a Laptop, Smartphone or Macbook directly from the USB-Stick to play. Ensure compatibility with popular formats, such as PDF, AVI or PPT.
- Contrast: on the basis of the ambient brightness, the contrast ratio of the projector is less important. About 3,000:1 is for the normal representation is sufficient.
- Resolution: For presentations and the execution of Standard programs is not a high resolution usually needed.
- What costs you projectors need to count, we explain in this article.
