Monitor sizes of 15, 17, and 19 inches refer to the diagonal measurement of the screen's viewable area in inches, rather than the total monitor width. These, often 4:3 aspect ratio screens, are smaller, older, or industry-specific displays suited for tight spaces, such as kiosks, POS systems, or basic, compact desktop setups.
15-inch: Compact, often used in older, embedded systems, kiosks, or minimal-space environments.
17-inch: A, frequently 4:3 or 5:4 aspect ratio, offering a small, square-like display suitable for basic office tasks and, in some cases, older, smaller-screen, or specialized equipment.
19-inch: Offers a slightly larger, often 1440x900 resolution (widescreen) or 1280x1024 (square) viewable area, providing more screen space than 17-inch models for general office work.
Key Considerations:
Measurement:
Taken diagonally from corner to corner, excluding the bezel.
Usage:
These sizes are primarily found in older, refurbished, or industrial, POS, or niche, space-constrained, or specialized environments, such as surveillance systems.
Aspect Ratio:
Many 17 and 19-inch monitors are 4:3 (square) rather than 16:9 (widescreen).
Resolution:
Lower than modern, standard 22+ inch, high-definition screens, offering lower, often 1280x1024 or similar, resolutions.
