How to determine the position of the projector for a given screen size

1.Select your screen size.

2.Refer to the table and find the closest match to your screen size in the left columns labelled "4:3 screen diagonal". Using this value, look across this row to the right to find the corresponding average distance from screen value in the column labelled "Average". This is the projection distance.

3.On that same row, look across to the right column and make note of the "Vertical offset in mm" value. This will determine the final vertical offset placement of the projector in relation to the edge of the screen.

4.The recommended position for the projector is aligned perpendicular to the horizontal center of the screen, at the distance from the screen determined in step 2

above, and offset by the value determined in step 3 above.

For example, if you are using a 120-inch screen, the average projection distance is 2182 mm and with a vertical offset of 91 mm.

If you place the projector in a different position (to that recommended), you will have to tilt it down or up to center the image on the screen. In these situations, some image distortion will occur. Use the Keystone function to correct the distortion. See "Correcting keystone" on page 30 for details.

How to determine the recommended screen size for a given distance

This method can be used for situations where you have purchased this projector and would like to know what screen size will fit in your room.

The maximum screen size is limited by the physical space available in your room.

1.Measure the distance between the projector and where you want to position the screen. This is the projection distance.

2.Refer to the table and find the closest match to your measurement in the average distance from screen column labelled "Average".

3.Using this value, look across that row to the left to find the corresponding screen diagonal listed in that row. That is the projected image size of the projector at that projection distance.

4.On that same row, look across to the right column and make note of the "Vertical

offset in mm" value. This will determine the final placement of the screen in relation to the horizontal plane of the projector.

For example, if your measured projection distance was 1.5 m (1500 mm), the closest match in the "Average" column is 1527 mm. Looking across this row shows that a 84-inch screen is required.

MP512 ST, MP522 ST specifications

The BenQ MP522 ST and MP512 ST are compact projectors designed to deliver impressive performance for both education and business environments. These models stand out for their versatility, high-quality image output, and user-friendly features.

The BenQ MP522 ST is known for its Short Throw technology, enabling it to project large images from a short distance. This feature is particularly beneficial in smaller rooms where space is limited. The projector can produce a 60-inch image from just over two feet away, making it ideal for classroom settings and small meeting rooms. The MP522 ST boasts a brightness of 2800 ANSI lumens, ensuring clear and vibrant presentations even in well-lit environments. With a native resolution of XGA (1024 x 768), it delivers sharp and detailed visuals, making text and images easy to read.

On the other hand, the BenQ MP512 ST shares many of the same features while offering slightly different specifications. The MP512 ST also uses Short Throw technology, allowing it to project large images in limited spaces. With a brightness of 2500 ANSI lumens, it provides adequate illumination for various settings. This projector also supports a native resolution of XGA, ensuring excellent image quality for presentations and videos.

Both projectors utilize DLP technology, known for its reliability and high-quality images. DLP projectors typically have better color accuracy and contrast ratios compared to other technologies, resulting in vivid and lifelike images. Furthermore, the long-lasting lamp life of up to 4000 hours in Eco mode enhances cost efficiency and reduces maintenance needs over time.

Another notable characteristic of both models is their connectivity options, which include multiple VGA inputs, a composite video input, and a USB port. This variety allows for easy connections to laptops, video sources, and even USB drives, making them versatile tools for presentations and multimedia sharing.

Both BenQ MP522 ST and MP512 ST projectors emphasize portability and ease of use. Their lightweight design and compact size make them easy to transport, while features such as automatic keystone correction simplify setup and ensure optimal image alignment.

In summary, the BenQ MP522 ST and MP512 ST projectors are excellent choices for users seeking high-quality, compact projectors with superior image performance. Their short throw capabilities, robust brightness, and extended lamp life, coupled with DLP technology, make them reliable solutions for a range of applications in education and business environments.
