What is an ANSI lumen?

 

This is measure of brightness as defined by the American National Standards Institute.   A brightness of 1500 ANSI lumens will project a good image in a well lit room.   Higher brightness allows larger images for presentations to more people. 

 

What is a multimedia projector?

 

Multimedia means that a projector will display data from computers as well as pictures from televisions and video recorders. Video only projectors cannot be used with computers.

 

Will the projector work with my make/model of notebook?

 

Sanyo projectors are designed to work with all notebooks, PC's and Apple Macs automatically.  Some new notebooks use XGA resolution which means that the screen display is made up of 1,024 dots across and 768 dots down.  If your were considering any SVGA  projector,  this projector will display an XGA image using 'intelligent compression' because it is only made for SVGA (800 x 600 dots).  Sanyo's 'intelligent compression' gives an excellent quality image but this is still not as good as a projector made for that resolution.  You would be advised to choice an XGA projector instead.

 

What is the PCMCIA card feature on some of the projectors?

 

This is available on a few of the projectors which allow you to give presentations without a computer.   Microsoft Powerpoint and Lotus Freelance Graphics presentations can be downloaded to a memory card (PCMCIA) which the projector then uses to display the presentation.   You receive all the software, instructions and cables you need to do this with your projector.   You can save different presentations on different PCMCIA cards which is especially useful if more than one person will be using the projector.

 

How many presentation slides can I fit onto a PCMCIA memory card?

 

You can put around 20 slides onto a 4Mb card and 40 onto an 8Mb card. This is a modest estimate because all slides will take up different amounts of memory space depending on the graphics used.

 

What is a rear projector?

 

Projectors are normally positioned in the middle or back of a room and project forward onto a screen.  A rear projector will display the image onto the screen from behind it.  The main advantage is that people cannot walk between the projector and screen blocking out the image.  Most Sanyo multimedia projectors can be used as rear projectors.  You would need either a rear projection screen or mount the projector in a rear projection cabinet.

 

Which technology do Sanyo projectors use?

 

All Sanyo projectors use tried and tested LCD (TFT) technology.  This involves using 3 TFT panels to produce a sharp, clear image.  This technology allows the projectors to stay cool so that they can be used for long periods or full-time if necessary. DLP is a newer technology which is still in the development stage.  DLP projectors currently run very hot and give a far poorer quality image.

 

Why is there a choice of lenses on some of the projectors?

 

Long-throw lens - Normally if you move a further projector away from the screen, the larger an image is projected.  This is fine if you want to use your projector at the front of a conference room/lecture theatre but it can be preferable to mount a projector out the way at the back.  Projectors available with a long-throw lens can be used to reduce the image size to fit a screen when the projector is mounted a long way away.  A semi long-throw lens works the same but for shorted distances.

Short-throw lens - This is the opposite of a long-throw lens.  These can be used when a projector is mounted very close to a screen to display a large image.  This is often used in rear projection systems.

 

Why choose a Sanyo projector?

 

Sanyo are the world's leading manufacturer of LCD projectors.  Sanyo LCD projectors are world renowned for their reliability and quality.  The technical support is second to none.  Sanyo projectors are used by thousands of UK organisations.
