The monitor feature that indicates the ability to display colors.
a. aspect ratio
b. contrast ratio
c. dot pitch
d. resolution rate
The Correct Answer and Explanation is:
The correct answer is c. dot pitch.
Explanation:
Dot pitch is the monitor feature that directly relates to the ability to display colors and overall image sharpness. It is defined as the distance between two like-colored phosphor dots (or pixels) on the screen, typically measured in millimeters (mm). In color monitors, each pixel is made up of three sub-pixels: red, green, and blue. These combine to create the full range of colors you see on the screen.
- Why dot pitch matters for color display:
The smaller the dot pitch, the closer the pixels are to each other, which results in a sharper and more detailed image with smoother color transitions. A lower dot pitch means the display can render colors more accurately and with finer detail because the sub-pixels are packed more densely. Conversely, a larger dot pitch results in more visible gaps between pixels, which can cause colors to look less sharp or slightly blurred.
Why the other options are incorrect:
- a. Aspect ratio
Aspect ratio refers to the proportional relationship between the width and height of the screen (for example, 16:9 or 4:3). While it affects the shape and size of the display, it does not influence the ability to display colors. - b. Contrast ratio
Contrast ratio is the difference in luminance between the brightest white and the darkest black a monitor can display. It affects how well the monitor displays differences in brightness and detail in shadows and highlights but does not directly affect color reproduction. - d. Resolution rate
Resolution rate refers to the number of pixels displayed on the screen (e.g., 1920 x 1080 pixels). Higher resolution means more pixels and potentially better detail, but the color quality depends on dot pitch and color depth, not just resolution.
Summary:
- Dot pitch affects how close the pixels are to each other.
- Smaller dot pitch → more tightly packed pixels → better color quality and sharper images.
- Color display depends on pixel density and quality, which is measured by dot pitch, making it the key factor for color display ability.
Hence, dot pitch is the correct answer when referring to the monitor feature indicating the ability to display colors.
