3.On that same row, look across to the right column and make note of the "Vertical offset (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 2422 mm, and the vertical offset is 91 mm.

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 on page 17 and find the closest match to your measurement in the average distance from screen column labelled "Average". Check that your measured distance is between the min and max distances listed on either side of the average distance value.

3.Using this value, look across that row to the left to find the corresponding "Screen size" 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 (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 is 4.8 m (4800 mm), the closest match in the "Average" column is 5046 mm. Looking across this row shows that a 250'' (about 6.35 m) screen is required.

Checking the min and max projection distance values on the columns of "Distance from screen (mm)" indicates that the 4.8 m measured projection distance will fit the 220'' size screen. The projector can be adjusted (using the zoom control) to display on this screen size. Be aware that different screens have different vertical offset values.

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 25 for details.

MP515 ST, MP525 ST specifications

The BenQ MP525 ST and MP515 ST are innovative projectors designed to deliver high-quality visuals for both educational and business environments. With a blend of advanced technologies and user-friendly features, these projectors offer exceptional performance.

Starting with the core characteristics, both models boast DLP (Digital Light Processing) technology, which ensures sharp images with vibrant colors and excellent contrast ratios. The native resolution of these projectors is XGA (1024 x 768), suitable for detailed presentations and videos. The brightness level for the MP525 ST is typically around 2500 ANSI lumens, providing sufficient illumination for well-lit environments. The MP515 ST, while slightly less bright, still delivers adequate performance for dimly lit rooms, making both models versatile for various settings.

One of the standout features of the BenQ MP525 ST is its short-throw projection capability, allowing users to display large images from a short distance. This is particularly beneficial in smaller rooms where space is limited as it minimizes shadows and enables presenters to stay close to their audience. The throw ratio is approximately 0.6:1, meaning it can project a large image within just a few feet from the screen.

Both projectors come equipped with a comprehensive connectivity suite, including HDMI, VGA, S-Video, and composite video inputs, ensuring compatibility with a wide range of devices such as laptops, DVD players, and gaming consoles. They also feature built-in speakers that deliver clear audio without the need for external sound systems, making them convenient for quick setups.

In terms of usability, the BenQ MP525 ST and MP515 ST are designed with user-friendly interfaces and remote controls. They include features like keystone correction to help adjust the image shape, ensuring perfect alignment even when the projector is angled. Additionally, the projector’s lamp life is impressive, reaching up to 4000 hours in economic mode, which reduces the need for frequent replacements and lowers operational costs.

In conclusion, the BenQ MP525 ST and MP515 ST projectors are excellent choices for educators and presenters who require flexibility, quality, and ease of use in their projection equipment. With their advanced DLP technology, short-throw capabilities, and versatile connectivity options, these models cater to diverse presentation needs while ensuring that every image is displayed with clarity and impact.
