I dream of LCOS

There's little for me to talk about today other than the fact that I really want one of the LCOS front projectors now. I've had LCD and DLP. I have to say of the two I think I prefer LCD. My current projector is an LCD project and it looks very good at 1080p.

It's about time to change the lamp in it. I've had the replacement lamp for some time. I mainly don't want to change until I get the most out of the current lamp. It seems to be a trooper though because it has around 3000 hours on it with very little decay in quality.

My old DLP projector blew a few bulbs in a short period of time. This may have been due to the lamps themselves or it may have been a flaw in that particular model of projector. I'm not sure. At any rate, lamps aren't cheap so I'll just stick with the one that's in it for a while longer.

Maybe someday soon, I'll be able to afford an LCOS to replace it. They are beautiful.

JVC D ILA HD (LCOS) Projectors

I know theres's a lot of alphabet soup in the title, but if you're interested in home theater projectors, you should keep reading.

Everyone who has researched projectors knows that there are two main types, DLP and LCD. Everyone has their opinion as to which is better. The truth is, they both have their advantages and disadvantages. For some time now there has been yet another technology that few were aware of. This technology is known as LCOS(Liquid Crystal on Silicon).

LCOS has many types. It seems that each manufacturer has their own version. One of the most popular is from JVC. It is known as D-ILA. JVC D ILA is a must for any videophile. LCOS technology hasn't taken off mainly because of the price. The price is effected directly by the fact that LCOS projectors tend to be on the higher end of the resolution spectrum.

LCOS projectors are also a bit larger in physical size typically. Price and size are about the only disadvantages, however. Pixels are super smooth. The display is very liquid in comparison to both LCD and DLP. LCOS uses the best of both worlds to produce a much higher quality picture.

So if you are in the market for a high quality projector for you home theater, do youself a huge favor and make sure it is an LCOS projector. You won't be sorry.

Powerpoint projectors

When searching for a powerpoint projector, one should look for how well the projector interfaces with computers, what native resolution the powerpoint projector will run at, and how bright the powerpoint projector will display.

In most business settings, powerpoint projectors are connected to a laptop/notebook computer. Most portable computer has a VGA connection. These are normally 15-pin connections and are blue in color. More modern laptops have a DVI connection. This connection is usually white and is a little wider than a VGA port. The powerpoint projector one chooses should allow for connectivity to one or both of these ports. If the powerpoint projector is to be connected to a desktop/tower PC, the same rules apply. Desktop/tower PCs all have either a VGA or DVI connection, sometimes both.

The connection is pretty universal but native resolution isn't. If the powerpoint projector is to be used by many different people, it should have a native resolution that is pretty common for laptop computers. At the moment, that resolution (for fullscreen laptops) would be XGA, or 1024x768. This is a good resolution for powerpoint projectors as it is very universal.

Lastly, one should take into consideration the ambient lighting where the powerpoint projector will be used. One should also consider the physical size of the screen the powerpoint projector will project. A good rule when calculating the lumens for a powerpoint projector in a business environment is if the diagonal size of the screen is less than 100 inches, a projector of 2000 lumens will be very adequate. Between 100 and 120 inches, the powerpoint projector should be at least 3000 lumens. Between 120 and 150 inches, the powerpoint projector should be at least 3700 lumens.

Check out this high rated business-class powerpoint projector.

Using these simple rules, can help any business person with little understanding of lumens and resolution find the right powerpoint projector.

Home Theater Projectors

Projectors make great additions to a home theater setup. My home home theater is actually comprised of only a projector and an RCA theater sound system. Frankly, I love this setup. About the only requirements for using a projector at home are a low-lit room with a good-sized wall. You can use a screen, which normally runs about $120, or you can use a wall with special screen paint.

I use one of my walls. The wall itself is about 20 ft long, which means I can have a good widescreen of about 100 inches diagonal. The maximum for my wall/projector combo is actually around 120 inches diagonal but reducing the size positively effects the quality. In other words, making the screen smaller, increases the intensity of the light beam itself, making a brighter, higher quality picture.

There are other positive reasons to go with a projector as opposed to a large TV. If you are worried about the resolution, rest assured that most of the latest projectors do 1080p. Most have HDMI, component, and s-video inputs. Most of them have VGA or DVI input for computers. There's one final advantage. This one is my favorite actually because I'm somewhat lazy. Projectors are much easier to move. :)
