A short guide to Video Projectors: Business vs Home Theater Projectors
Posted by: darnellhamza in Mobile Projector Articles, tags: Business, Projectors, TheaterMultimedia projectors, today is a versatile tool, convenient and affordable that for various purposes, both now and in the home entertainment scene can be used.
Falling prices and technological developments in video projection, we have in recent years, the digital projector even more accessible to a wider group of users at home have.
Demand has risen so that the objects are not onlyProduction of so-called "crossover" models – projectors, both PowerPoint presentations in the office and handle DVD movies at home, but they have also started to design the realm of entertainment with the production of models designed for home theater use. . .. target Why?
It is true that the cross-over projectors that handle both worlds, but that does not mean that a video projector for providing a beautiful presentation in the boardroom of the situation alsocan be a great movie experience in home theater systems.
Meet home theater projectors and business projectors to the different needs in their use can be achieved if the video projector designed specifically for this purpose.
What characteristics distinguish the business projector home theater projectors?
It is no surprise that video projectors are always a popular choice among many home theater enthusiasts.The digital projector to the larger picture for your money. Simply connect your DVD player and you have the film more than a picture on the home theater. Or connect a high definition source like a cable set-top box or satellite receiver, and we have a huge 100 "HDTV for the cost of a 50" plasma TV.
And prove in the boardroom, now powerful digital multimedia projectors, more than ideal for business presentations are capable of large brightin normal room lighting – just something dreamed in the days of overhead. Simply plug in your laptop, and here the best shops present in the world!
However, it is important to note that in the meeting room and home theater are two different areas, different animals require. The requirements are important between the two, the discussion that follows explains the various attributes of a video projectorapplies in both cases.
Important attributes Projector
Brightness
The degree of brightness (measured in lumens or ANSI lumens) is an indicator of the degree of light on the projector. The brightness is much more important for trade – in this respect that many classes are in conference rooms with the venue lighting, rather than a reduction of ambient light. This means that the image is bright enough to be, musttimes, otherwise the projection would look washed.
For small conference rooms and presentations with lots of ambient light, a brightness of about 1000-1500 lumens should normally be OK. However, keep in mind that the projector brightness required by the size projected on the screen depends on the ambient light and increasing the screen (more in our guide) to the projector screen.
For home theater applications is not a high level of brightness important. A little bit "offor use with home theater projector with lamp setting to the user the option of the light source for display better and deeper black is dim when viewed in a dark room.
Contrast:
As stated in our article contrast ratio, a minimum level of ambient light in May at the image a high contrast of 5000:1, to say, as with a contrast ratio of 500:1. This means that if there is a level of contrast to the eye to an importantsufficiently bright picture, but the contrast is not an important feature in business applications, or that is in use at home when the projector in the room with light.
In reality, nothing more than to 400:1 contrast ratio is not perceived by the eye when you have no place in a completely darkened. Moreover, it is to say due to a contrast sensitivity function of the eye, a contrast ratio of 2000:1, which is not so exercised five timesbetter than one with a contrast ratio of 400:1. So pay more and go for a contrast ratio higher in the case of a home theater projector that is until the display carried out in a controlled lighting.
Color, gray scale, performance and smooth video playback:
These are all attributes that are in most home theater applications is crucial. In fact, the color accuracy with natural colors of skin care and the ability to fine details in bright and dark areas of modernPicture of the substance into the user home.
Similarly, the projector has the ability to read, is ultra-smooth video without motion artifacts during the presentation of sports and fast action scenes from the film, of the utmost importance in any home theater applications.
LCD or DLP:
Depends. Strictly speaking, both technologies could have done a good job in one of these applications in this advancement in technology that reduces the gap between the two. However, LCD projectors usuallyfirst choice, with lamps of the things that still have an advantage because the brightness DLP.
On the other hand, the DLP technology is always supported when it comes to home theater use because of their better performances of the black level and smooth projections closer to those movies.
Portability:
This is a serious problem with the external video projector. Smaller and lighter is better, especially if you travel frequently. Weight Longer a problem for the professional user. The mobile business professionals who want a projector to connect light for a desktop or laptop, projecting an image onto a large screen for presentations or on the wall.
Other activities focused projectors weigh only a few pounds – some business models very light weight no more than three pounds lost! These projectors are normally allow with the kit and wireless remote control if the user not only gains control> Projectors, but also to send commands to the computer via a suitable connection. Some remotes are equipped with a built-in laser pointer.
Most projectors in this category are a small speaker for sound, more expensive projectors, security features such as locking cables, etc. equipped
The portability issue is not even relate to home theater. We do usually have a permanent place for the projector. For home theater projectors, the best configurationStain on the ceiling. This means that some should go into planning how it is best to get cable installed in the ceiling to connect the projector, the rest of your home theater.
Projector Connectivity
It is important that the projector is equipped with the appropriate entries for you to be connected to your PC or laptop, in the case of a lighting company, craft and home theater, DVD or HDTV set – top boxes, in case ofHome Theater Projector.
It is clear that the varied needs of the connection between these two categories: video projector.
Most – but not all – the models of components and support, composite, S-Video and RGB connectivity. Home cinema projectors in general also have a DVI or HDMI connection, which is very useful when it comes to interconnection with a compatible DVD player or HDTV set-top box.
A standard information, which is understood more video projectors in the making, and is moreappropriate in the business world, is called the M1, EVC or P & D standard, which is more common than M1 or M1-DA.
The connector allows the M1-DVI connectivity itself – the single-or dual-transfers in the case of digital or analog DVI-I combines. But the advantage of the M1 via DVI, the M1 also supports connections via USB or FireWire port on your PC. The USB / FireWire is used to the projector's remote computer- Allow the user to browse PowerPoint presentations, etc.
Check Our advice: before buying to ensure that the projector has inputs you need.
Projector Resolution: SVGA, XGA or wide-screen (WVGA or WXGA)?
This refers to the native resolution or optical and measuring the level of detail of the image that (the projector will process the uncompressed size can) the number of pixels of the original video content. Downscalingaffect the image quality and leads to loss of image content.
This is probably by far the most important attribute of a video projector, that the activity of different home theater projectors. In fact, this is not the number of pixels, but the manner in which they arranged on the screen at a height over the entire width, which is the native aspect ratio of the projector.
SXGA (1280×1024) is currently the highest resolution available for portable projectors, video projectors are therelatively expensive. Most of the video projector is in 4:3-resolutions are XGA (1024×768 pixels), SVGA (800×600 pixels).
Versions SVGA (WVGA: 854×480) and XGA (WXGA have: 1280×720) started to occur. These projections provide a better 16:9 content.
Business Video Projectors: SVGA and XGA projectors are suitable for business presentations is high-resolution XGA projectors no longer be able to demonstratefine details in the presentation.
Many things in May, the higher the resolution the better – but need not, in the case of business-used projector. A word of caution here arise from the fact that if the text in a PowerPoint slide with a scripture small, to show, ie with a SVGA projector (and therefore requires the need for an XGA projector) The likelihood that the public while the soil is not yet able to read it.Surely you do not want. Make under these circumstances, it would be cheaper SVGA projector – in most cases – be able, more than a good job.
On the other hand, the XGA projector is the best option for presentations, graphics, software demonstrations, or full web pages, this resolution also provides a better measure of the screens of laptops included.
Home Theater Projectors: If you want to use a video projector to project an image of the massivea picture in your home theater, the higher the resolution the better, because you are less prone to suffer from aliasing. It is true that pixelation disappears as the distance from the screen, but in home theater, most people prefer a little "closer to moving on the corner of a larger vision and a film of immersion experience.
Although most SVGA projectors in high-definition images can display HD tuner from your cable or satellite, the resolution is not sufficient toJustice. The two main HD formats are 1080i (1920 x 1080 pixels) and 720p (1280 x 720 pixels). SVGA 800 x 600 pixel resolution, have shown the possibility of either format without scaling.
Even with the DVD content – the 852×480, comes with a lower resolution HDTV – low prices, SVGA projectors can not do a good job with DVD movies. XGA, on the other hand, is much closer, but …
Standard two projectors have SVGA XGA4:3 aspect ratio for which the image corresponds to a standard computer monitor or television standard. Widescreen – as the available DVD and HDTV programming – an aspect ratio of 16:9. It is best for a home theater projector with a native widescreen resolution to use is the only way you can use the letterbox to avoid image lines or crop the image, or other technical aspect of relationship management, which are often used to present content in 16:9 formaton a 4:3-screen.
The projectors are in WVGA or WXGA available. The decision for the projector WVGA less sense if you only see DVD movies. The contents of HDTV XGA projector is required. This means that all content will be the HDTV display up to 720p without scaling. Will still be able to 1080i HDTV on an XGA projector in sight, but the projected image will be compressed to the 1920×1080 pixels on a 1080i or 1080p HDTV readyon the ground pixel in a video-projector XGA.
