● Formulas for calculating projection distance by projection lens
Check the projected image size SD (m) and use the following formula to determine projection distance.
(Values obtained by the calculation formulas in the tables below contain a slight error.)
When calculating a projection distance using image size designation (value in inches), multiply the value in inches by 0.0254 and substitute it into SD in the formula for calculating the projection distance.
Note
- The throw ratios are based on values during projection of 3.81 m (150") projected image size.

Standard installation dimensions (continued)
The dimensional relationship between the screen and the projector is shown below.
Establish the dimensions after assessing the area possible for installation.
■ Dimensional relationship diagram
● The illustration shows the ET-PKD520H ceiling mount bracket mounted on a projector.

Note
● This illustration assumes that the projector will be installed so that the projected image fills the screen and is properly aligned with it.
● This drawing is not in exact scale.
● The PT-RQ13K / RZ12K / RS11K is not supported by the ET-D3LEW200.

Standard installation dimensions (continued)
Attention
- Install the projector at a sufficient distance from the surrounding walls and objects so that the air intake and exhaust ports of the projector are not blocked. For details on the distance, refer to the operating instructions for your projector.
- Avoid setting up in places which are subject to sudden temperature changes, such as near an air conditioner or lighting equipment (studio lamps, etc.).
Note
- When [GEOMETRY] is used, correction is performed in the direction that results in a screen smaller than the specified screen size.
- The illustrations of projectors in this manual are for informational purposes only and do not represent a specific model. Configurations may vary with the model.

- Formulas for calculating projection distance by projection lens
Check the projected image size SD (m) and use the following formula to determine projection distance.
(Values obtained by the calculation formulas in the tables below contain a slight error.)
When calculating a projection distance using image size designation (value in inches), multiply the value in inches by 0.0254 and substitute it into SD in the formula for calculating the projection distance.
Note
● The throw ratios are based on values during projection of 3.81 m (150") projected image size.

■ Dimensional relationship diagram
● The illustration shows the ET-PKD520H ceiling mount bracket mounted on a projector.
(Units: mm ("))

Note
- This illustration assumes that the projector will be installed so that the projected image fills the screen and is properly aligned with it.
● This drawing is not in exact scale.
● The PT-RQ25K / RQ18K / RZ24K / RZ17K / RZ14K is not supported by the ET-D75LE90.

Standard installation dimensions (continued)
Attention
- Install the projector at a sufficient distance from the surrounding walls and objects so that the air intake and exhaust ports of the projector are not blocked. For details on the distance, refer to the operating instructions for your projector.
- Avoid setting up in places which are subject to sudden temperature changes, such as near an air conditioner or lighting equipment (studio lamps, etc.).
- Regardless of the projector model, set up the projector so that the projected image is rectangular and the back of the projector and the screen are parallel. Depending on your projector, however, keystone distortion correction via the [GEOMETRY] function may be possible, even after setup. For details, refer to "Setting up" in the operating instructions of the projector.
Note
- Dimension L4 is not the distance from the projector rear panel to the wall, but the distance from the projector rear panel to the screen.
- When [GEOMETRY] is used, correction is performed in the direction that results in a screen smaller than the specified screen size.
- The illustrations of projectors in this manual are for informational purposes only and do not represent a specific model. Configurations may vary with the model.

● L1, A1 calculation formula
Check the projected image size SD (m) and use each formula to determine projection distance (L1) and top of set to top edge of screen (A1).
By determining L1 and A1, you can calculate all other dimensions.
(Values obtained by the calculation formulas contain a slight error.)
When calculating a projection distance using image size designation (value in inches), multiply the value in inches by 0.0254 and substitute it into SD in the formula for calculating the projection distance.
