Can 2 projectors of different brands be connected together and work at the same speed?

I have an EPSON SVGA projector.
I will be getting another projector today that may be of another brand. I want to know if I can connect the two if they’re of different brands.
Will they work at the same speed? Close quality?
Anything I should know?

Thanks!

Different Kinds Of Home Theater Projectors

Home theater systems have come a long way in recent years and video projectors are fast becoming the popular choice for the home theater enthusiast. You can enjoy the experience of the movie theater without leaving your own home. Projectors have been coming down in price over the years and the average person can now purchase an affordable, high quality unit.

At this time there are three different types of video projectors available for the home theater enthusiast. They are the CRT, LCD, and DLP and you will need to research each type as each has it’s own advantages and disadvantages. You will have to decide what your needs are and what your budget is before you can make a decision on which is best for your situation.

CRT stands for cathode ray tube and they have been in use for over 50 years. They are long lasting and reliable and also provide excellent image quality. Image sharpness is outstanding but brightness is not up to par with the other two kinds of projectors. The major drawback to CRT is that they are very large and bulky so you will need more space in order to utilize a CRT projector.

LCD or liquid crystal display, can display a huge variety of colors and project an extremely bright and sharp image. They are also very affordable because this technology has become so popular over the years. Even so, you will have to replace bulbs often which can cost up to a several hundred dollars. So if you decide on a LCD projector make sure that you take this into account and budget for this expense in the future.

DLP stands for digital light processing and is the newest kind of home theater projector and is rapidly gaining in popularity. DLP technology is just as bright as the LCD but it has far superior contrast range. They are also very lightweight and do not take up much space. As with LCD, bulbs need to be replaced and are quite costly.

What Are The Different Types Of Home Theater Video Projectors?

Home Theater is a recent concept and is fast becoming an affordable way for everyone to enjoy the experience of the theatre – the big screen and surround sound – right in the comfort of their own home.

There are several choices for displays when designing your own home theater. Most usually, consumers will opt for a large CRT (box shaped) television, usually in widescreen format but sometimes in the old 4:3 format, else they will opt for the newer and thinner plasma screens available. However, it is worth considering home theater video projectors as they can come closer to offering the true theater experience compared to traditional televisions.

A home theater video projector can enhance this experience and is probably the most affordable solution that gives rise to the largest screen possible in the residential environment.

Whereas video projectors used to be expensive and of poor quality compared to the traditional alternative, the television, these days the technology has dropped considerable in price and is within reach of most home theater enthusiasts. Furthermore, the quality, brightness and sharpness of the image are vastly improved.

There are currently three main different types of home theater video projector – CRT, LCD and DLP.

CRT (cathode ray tube) video projectors are what you really get in a true theatre – they are the machines with red, blue and green lights. The advantages of such devices are a long lifetime and a proven, tried and tested technology that has stood the test of time for well over half a century. They also provide high image quality and sharpness. Unfortuantely, they are usually quite large, bulky and heavy. As well as this, they tend not to be as bright as their more recent digial counterparts.

LCD (liquid crystal display) video projectors use lcd wafers (like your digital watch) to either block out light completely, pass it completely, or somewhere in between. When you consider that this can be done for all three primary colours (red, green and blue) you can see that a large variation can be created and hence a projected image. Such LCD projectors are very lightweight and bright, and tend to be affordable due to the widespread use of lcd technology. Unfortunately, they suffer from a poor contrast range and bulbs need replacing very often. Bulbs are not cheap and can cost several hundred dollars depending on your model of projector – this running cost is a consideration that you should make when selecting your projector.

DLP (digital light processing) are the newest type of home theater projector. They operate in a similar fashion to lcd projectors, except that instead of lcd wafers, they use silicon chips called digital micromirror devices, or DMDs. The result is again a lightweight device as with LCD, but also brighter display and a better contrast range that its LCD brother. However, again, running costs i.e. bulb replacements, are very high.

Understanding Different Tv Technologies

Anyone who has been watching TV for a few decades now tends to feel that flat panel television is the best thing to have happened to television viewers. The market is now flooded with advanced television technology in the form of plasma televisions, LCD televisions, DLP televisions and projection TV.

It’s The Difference:

Flat panel televisions comprise of Plasma, LCD, rear projection, and DLP TV. These terms can appear confusing to someone who is trying to decide on which of these is best. Here is a quick look at what goes behind each of these technologies to bring those fantastically real images to the viewer:

Plasma Television: In the flat panel category, in plasma televisions, a variety of gases like neon argon and xenon emit light and color to the TV screen when they are stimulated by electrical impulses. There is a matrix of miniature phosphor coated gas plasma bubbles, which are powered through electrical impulses that result in the formation of the picture. There are some really wide plasma screens available, exceeding thirty inches, with stunning images with the sharp contrast. Plasma televisions are better than liquid crystal displays because they are faster in terms of response, offer a more wide viewing angle. The picture display quality appears far better.

LCD Television: Also called liquid crystal display TV, these are also flat panel TVs. The technology works when a solution of liquid crystals is sandwiched between two glass panes. This solution carries electrical charges. A florescent bulb emits white light, which the crystals block and reflect, which results in the picture the viewer sees on the screen. LCD TVs are very popular with an ever-increasing market. They last long, are slim and energy efficient.

DLP TV – DLP or Digital Lighting Processing technology has come in recently. These projection TVs use a computer chip equipped with innumerable mirrors, which project and then reflect the picture. The picture quality is superior. Today, many home theater systems and entertainment projectors use this technology.

HDTV or High Definition Television is basically a digital format. A viewer can really enjoy the experience of HDTV when the show is made using high definition technology and broadcast through an HDTV signal via an HDTV TV channel to an HDTV television. There are HD ready TV sets in the market today. These have a screen that can display the HDTV signal. It requires an HDTV receiver/decoder to broadcast the signals.

Rear Projection TVs These are large-screen TVs that are more reasonably priced than the others, giving the viewer a great option that combines size with price. Most of these support the HDTV format. Rear Projection TVs use different technologies to produce their pictures and this can be CRT, DLP or LCD. They can be thin and light and have to be viewed straight on to get the best effect.

The great thing about these TVs is their amazing color clarity and life like visuals, making the viewer feel as if she or he is a part of the scene. Market leaders in this field are Panasonic, Toshiba, Hitachi, Samsung, Philips, etc. There is no such thing as the best TV; what really matters is what features matter most to the viewer and consequently what might be a pro for one viewer might well be a con for the other.
