ecent versions of Windows, starting with Windows 98, let you
select a large icons option in the Display properties sheet. This
enables you to use high-resolution selections (which help you see
more of your document) and still have large, legible icons.
Table 10.3 shows the minimum-size monitors I recommend to
properly display the resolutions that users typically select.
Table 10.3 Resolution and Monitor Size Recommendations
Resolution Minimum Recommended Monitor
640×480 13-inch
800×600 15-inch
1,024×768 17-inch
1,280×1,024 21-inch

LCD Versus CRT Display Size
LCD panels, especially all-digital units, provide high-quality displays
that are always crisp and perfectly focused. Plus, their dimensions
are fully usable and can comfortably display higher
resolutions than comparably sized CRTs. Table 10.4 provides common
CRT screen sizes and the comparable LCD display panel sizes.
Table 10.4 CRT Versus LCD Usable Screen Size Comparison
CRT Monitor Size CRT Viewing Area Comparable LCD (Also
Display (in Inches) (in Inches) Viewing Area in Inches)
14 12.5 12.1
15 13.5 13.3, 13.7
16 14.5 14.1, 14.5
17 15.5 15, 15.1
19 17.5 17, 17.1
20 18.5 18.1
As you can see, a 15-inch LCD actually provides a usable viewing
area similar to a 17-inch CRT.
Monitor Power Management
Modes
One of the first energy-saving standards for monitors was VESA’s
Display Power Management Signaling (DPMS) spec, which defines
the signals a computer sends to a monitor to indicate idle times.
The computer or video card decides when to send these signals.
