* The above figures are design values only. Actual distances will be within ±10% of those provided.
* Projection distances other than those in the above table can be obtained by the following formula.
Projection distance = (K1) x diagonal screen size + (K2)
* The projection distance for panel aspect ratio 4:3 is the value when an XGA (1024x768) or SXGA+ (1400x1050) signal is input.
The projection distance for panel aspect ratio 17:10 is the value when a WXGA (1366x800) signal is input.
* The projection distances for screen sizes 16:10, 16:9 and 4:3 can be obtained by the following formulas depending on the panel aspect ratio.
For panel aspect ratio 4:3
For screen size 16:9: Projection distance = (K1) x 0.8171 x diagonal screen size + (K2)
For panel aspect ratio 17:10
For screen size 16:10: Projection distance = (K1) x 1.0453 x diagonal screen size + (K2)
For screen size 16:9: Projection distance = (K1) x 0.9669 x diagonal screen size + (K2)
For screen size 4:3: Projection distance = (K1) x 1.1834 x diagonal screen size + (K2)
