Answer: B. 240×135.
Answer analysis: This question mainly examines how to calculate the resolution given the cabinet display size and dot pitch. First, we need to clarify the two key parameters given in the question:
* Cabinet display size: 600mm × 337.5mm
* Dot pitch: P2.5, i.e. 2.5mm
The resolution is calculated by dividing the cabinet display size (in millimeters) by the dot pitch (also in millimeters) to obtain the number of pixels in the horizontal and vertical directions.
1. Calculate the horizontal resolution:
Horizontal resolution = 600mm/2.5mm dots = 240 dots
2. Calculate the vertical resolution:
Vertical resolution = 337.5mm/2.5mm dots = 135 dots
Combining these two results, we get a resolution of 240×135.
Next, we compare the options:
A. 220×140: It does not match the calculation result, so it is excluded.
B. 240×135: It matches the calculation result and is the correct answer.
C. 300×168: It does not match the calculation result and is excluded.
D. All of the above: Since options A and C are both wrong, option D is also wrong.
In summary, the correct answer is B. 240×135.
