- If the measurement of the screen diagonal is not in
the table, C can be determined (in cm) as follows.
- Measure the screen diagonal and take the nearest
value from the table.
- Calculate the ratio between value C and screen width
in the table.
- Multiply the result by the actual screen width.
Example: Suppose we have a 105” screen diagonal. 100”
is the nearest value in the table.
Ihe C/Width ratio is equal to :305/203.2=1,5.
A105” screen diagonal is 213.3 wide.
So, the value of C is: 1,5x213,3=320 cm.
Note: The screen size refers to the useful area (4/3
format).
