For example, if you are using a 120-inch screen, the average projection distance is 1.53 m and with a vertical offset of 27 cm.

If your measured projection distance is 2.0 m (200 cm), the closest match in the "Distance from screen (m)" column is 1.91 m. Looking across this row shows that a 150'' (about 4.0 m) screen is required.

All measurements are approximate and may vary from the actual sizes.BenQ recommends that if you intend to permanently install the projector, you should physicallytest the projection size and distance using the actual projector in situ before you permanentlyinstall it, so as to make allowance for this projector's optical characteristics. This will help youdetermine the exact mounting position so that it best suits your installation location.
