What primarily controls the display monitor spatial resolution?

• A. Matrix Size
• B. Object-to-Image Distance (OID)
• C. Source-to-Object Distance (SOD)
• D. Cathode Filament

Answer: (A)

Display spatial resolution is determined by how finely the image is sampled, which is set by the matrix size of the digital image. The matrix size defines the number of pixels across and down; more pixels mean the image can represent finer detail when shown on a monitor, up to the monitor’s own pixel density. Object-to-image distance and source-to-object distance affect geometric sharpness in the captured image (magnification and blur) but do not change the image’s pixel grid. The cathode filament influences exposure and heating, not the sampling resolution of the image. So the matrix size is the primary factor controlling how much detail the display can show.
