Projection Industry sudden emergence of a new round of competitive projectors - projectors - Education Industry
In the past year, the successful holding of Beijing Olympic Games, Financial Tsunami engulfed the global assets of China's four trillion investment plan introduced, and so on. These are brought to the projector industry, not a small effect, 08 showed atrophy of education projector market, business market in the aftermath of the financial crisis, the current cold spell slower growth than in the past, but the domestic market is still got the projector about 20 % growth Sell Number to 57 million units, marking the projection industries remain healthy. China 4 trillion investment plan introduced in 2009, business, education, especially the booming construction market is brewing a projection competition.
Today Projectors Areas of rapid growth in sales volume to grow exponentially, has become the projector market with the most growth potential in one product line. 2008 Olympic Games in extensive use of the projector works to raise awareness of the high-end large-screen projector in the impact of the value. Projector for the project laid the foundation for the development, but really to promote the market development project projector projects a major factor in the projector market is gradually maturing, the current public places as well as major institutions and so widely adopted projects have begun projector projectors make more extensive range of applications. To this end, we are the majority of the domestic market, high-end projection products has been studied and found some of the important features.
Technology Strong
Resolution and brightness of a projector projects an important indicator to the higher resolution and brightness seems to be the major strength of the brand to show off the technology arena, however, resolution and brightness need to focus their Mitsubishi is not the better recently pushed the two works with projectors Mitsubishi GX-6400, GW-6800 in which 6400 and 5000 lumens XGA (1024 × 768) resolution and 6800 lumens of brightness, and 4,000 WXGA (1280 × 800) resolution, a rich product line to better explain Mitsubishi projectors have a strong technical strength and colleagues provide consumers with wider choices. Also worth mentioning is the Mitsubishi intuitive to allow consumers the quality of the projector, the projector internal structure of the public. Invite the industry to hold the projector dismantling media experiment, the vendors, the public need for dismantling the projector is a strong confidence in the product.

Strong stability
Today's modern society, technological development, video surveillance system has become water, electricity, coal and other industries essential safety equipment. Video Equipment Monitoring and Control System as the core device requires its own long-lasting stability, stability can be a long time, this precision instrument for the projector as it is very difficult. For high-brightness projector in the process of using power to bring the high heat, long time stable job even more difficult. Mitsubishi projector as an example to use the new Mitsubishi GX-6400/GW-6800 lamp drive system, integrated into the optimization of optical design bulbs work, creating a time in a long time after use can still maintain a stable shape of the electrode lamp system, delayed the projected loss of brightness. Put an end to the projector lamp electrodes in a long time to accelerate the use of brightness loss caused by the aging problem. The machine is equipped with lamp temperature control system so that up to 4000 hours lamp life. Based on DLP technology and DLP chip itself has the characteristics of internal body makes no filter to filter dust, and therefore need periodic cleaning. Machine within the closed system also ensures protection against dust and light color wheel access for cleaning, the new model will be the color wheel Sensor Installed close to the axis of rotation all closed within the motor casing, making it difficult sensors gather dust. The new design of optical channel closed to prevent dust from entering the optical channel, but also makes the brightness of the hold time longer.

what is the difference between business projectors and home theater projectors?
Through using google I got mixed answers.
I was looking at this one to use it as mostly for movies and video games, but it through me off because the description was that it was a business projector [even though it says its name is a WXGA DLP Multimedia Projector (so i think multi use when i see that)]

So i guess what im asking is if there will really be a drastic impact in quality for not using it for "business" use and more hd movies, etc.
Typically speaking, when comparing Home Theater projectors to Business/Multimedia projectors, the Multimedia projectors tend to have:
* Lower Resolutions (usually 800x600, 1024x768 or 1280x800, however some models can have native resolutions as high as 1920x1080)
* Full-Screen Aspect Ratios (4:3 is good for PowerPoint presentations and similar but not for the Home Theater, some models do come with 16:9 native aspect ratios though)
- Higher Brightness (Business/Multimedia projectors tend to be brighter because they are designed to overcome ambient room light whereas a Home Theater projector assumes no or little ambient light)
- Lower Contrast Ratios (as somewhat of a consequence of being brighter, most multimedia projectors tend to have lower contrast levels. Contrast levels are seen as more important for watching films than for a PowerPoint presentation or the like).
Generally speaking, the design for multimedia projectors is centered around creating bright images with high visibility in ambient lit conference rooms whereas Home Theater projectors are more concerned with reproducing accurate colors, shadow-detail, and contrast - ultimately creating a truer representation of the film and a better quality picture.
