Which factor will produce a monitor capable of displaying greater spatial resolution?

• A. Large number of pixels
• B. Higher brightness
• C. Faster refresh rate
• D. Larger physical screen size

Answer: (A)

Spatial resolution is about how finely a display can sample an image. It depends on how many picture elements, or pixels, the screen has across its width and height. When there are more pixels, there are more samples per area, so fine details—like thin lines and sharp text—can be shown more clearly. If you increase the number of pixels while keeping the screen size the same, pixel density goes up and the image looks crisper, enabling higher spatial resolution. Brightness, refresh rate, and screen size affect other aspects of display quality but don’t increase the number of samples used to form the image. Brightness changes luminance, not detail. A faster refresh rate smooths motion but doesn’t add more detail per frame. A larger screen with the same pixel count spreads those pixels over a bigger area, reducing pixel density and potentially making the image look less sharp. So the factor that directly increases spatial resolution is having a larger number of pixels.
