Introduction to the MultiSync 4FGe color monitor
The MultiSync 4FGe monitor allows you to “plug and play”; the MultiSync technology provides you with automatic
compatibility with multiple operating platforms and a vast array of graphics standards allowing resolution upgrades
without upgrading the monitor.
The larger
15”,
high contrast, flatter screen offers improved clarity and enhanced color and image quality.
ColorControl allows you to adjust the colors on your screen to exactly what you want. Thus eliminating
misrepresentations and frustration.
The MultiSync 4FGe monitor strictly follows
ErgoDesign
guidelines.
ErgoDesign
describes a philosophy governing
the design of the MultiSync monitors. The goal of
ErgoDesign
is to maximize the comfort and productivity of the end
user.
Feature Highlights
Multiple Frequency Technology
The Multiple Frequency Technology automatically adjust the monitor to the video card’s scanning frequency thus
displaying the resolution you require. The MultiSync 4FGe also supports multiple operating platforms including IBM
compatible and Macintosh family systems.
Increased resolution adds to the image clarity, and the MultiSync 4FGe monitor provides a wider range of higher
resolution to meet your needs for now and in the future.
A wide Range of Graphics Standards is displayable by the MultiSync 4FGe monitor including:
VGA at 640x480 l
60,72
and 75 Hz
Super VGA at
800x600-60
and 72 Hz
MAC II and Quadra at
640x480-67
Hz
MAC II and Quadra at 832x624 l 75Hz
8514/A and XGA at 1024x768 Interlaced
XGA-2 up to 1024 x 768
1024x768 Non-Interlaced 70, 72 and 76 Hz
Screen Technology
A High Contrast Tube with a 0.28 mm dot pitch increases the clarity and displays greater detail. Good clarity allows
your eyes to flow over the screen image and more easily absorb the information.
The Flatter Screen of the MultiSync 4FGe monitor reduces distortion of your image.
Increased Brightness provides higher contrast and more vivid colors.
