1. All of Apple’s
Cinema Display monitors
feature widescreen
design, with
20-, 23-, and 30-inch
LCDs optimized for
image editing. The
two larger models can
display HDTV content.

2. Dell’s flagship
flat panel LCD is the
30-inch UltraSharp
3007WFP, with panoramic
2560 x 1600
resolution (requiring
a deluxe dual-link
DVI graphics card),
a tilt/swivel/heightadjustable
base, and
four USB ports.

3. Eizo Nanao Corp.
specializes in precise
color-calibrationcapable
monitors
for graphics professionals.
The 19-inch,
1280 x 1024-pixel
ColorEdge CG19 offers
a 10-bit color lookup
table with choice of
sRGB, custom, or
calibration-tuning
brightness levels.

4. The Gateway
FPD2185W is a 21-inch
widescreen (1680
x 1050) LCD with a
1,000:1 contrast ratio,
landscape/portrait
pivoting, and a handy
array of VGA, DVI, SVideo,
composite, and
component inputs.

5. Seen here in both
standard landscape
and page-friendly
portrait mode, HP’s
LP2065 is a 20-inch,
standard-aspectratio
(1600 x 1200)
display that’s switchable
between two
inputs—your desktop
and laptop computers,
for instance.
|
|
|
6. Available with or
without a hardware
color calibrator, the
LaCie 321 is a 21.3-inch
LCD monitor designed
for color-accurate soft
proofing. This model
is advertised as having
a CRT-grade color
gamut (72 percent of
the NTSC palette).
|
|
|
7. Tilt-, swivel-, height-,
and pivot-adjustable,
the Samsung Sync-
Master 204B is a 1600
x 1200 flat panel with
an 800:1 contrast
ratio and super-thin
(just over half an inch)
bezel that makes it
ideal for side-by-side
tiling of two displays.
|
|
|
8. With 1920 x 1200
pixels spread over
a 23-inch screen,
ViewSonic’s VP231wb
is a high-end widescreen
display with
digital and analog inputs.
One caveat: It’s
capable of portraitmode
pivoting, but
this feature is supported
only on PCs,
not Macs.

Three tech types
An LCD monitor’s
feature list should say
which of three liquid
crystal technologies it
uses. If it doesn’t, the
display is probably the
cheapest and most
common, twisted
nematic (TN). TN
offers quick response
but not the best contrast
ratio or viewing
angle. Color reproduction
is mediocre. Some TN screens
can’t display all 16.7
million colors, slipping
to 16.2 million or using
dithering—rapid alternation
of two colors to
make a pixel appear
to be a third color—to
mimic 24-bit color.
Two high-end alternatives
top TN’s performance,
though there’s
no decisive winner
between the two:
• Vertical alignment,
identified as MVA
(multidomain vertical
alignment) and S-PVA
(super-patterned vertical
alignment), offers
sharp contrast and
image quality with
wide viewing angles.
• Flat panels aimed
at professionals often
use in-plane switching
(IPS) technology,
which boasts superb
CRT-class color
reproduction, wide
gamuts and viewing
angles, and dark
blacks. Response time
has caught up to TN
speeds, though contrast
and brightness
don’t quite match the
best VA panels.
SIDEBAR: Plugging Them In
LCDs are digital devices, but inexpensive
models use the same analog
signals as good old CRTs, usually via
VGA (Video Graphics Array) cables
that end in 15-pin D-sub connectors.
Changing analog to digital data for
display is a bit inefficient, but modern
monitors are good at it; most monitors
plugged into a VGA connection
receive plug-and-play info that adjusts
and centers the screen instantly.
Mainstream flat panels have—and can
switch between—analog and digital
inputs. The latter use the DVI (Digital
Video Interface) connector found on
a growing number of midrange and
high-end computer graphics adapters.
DVI comes in two flavors: DVI-D
carries only digital data, and DVI-I can
transfer both digital and analog info.
HP’s LP2065 monitor makes things
easy by providing two DVI-I jacks plus
two DVI-I-to-VGA and two DVI-I-to-
DVI-D cables, so it can accommodate
any pair of video sources (both your
desktop and laptop PCs, for instance).
Dual-input monitors usually let you
use their front-panel controls to flip
between two images or arrange them
in a side-by-side or picture-in-picture
view. The latter is particularly tempting
if one input is a TV signal: Some
flat panels team VGA and/or DVI connectors
with S-Video or component
video inputs, while some such as
Sony’s MFM-HT205 are monitor/TV
combos with built-in TV tuners (for
now, just NTSC analog instead of
HDTV tuners).
One monitor for everything?
It’s just as well that hardworking
designers would never dream of
watching TV—especially HDTV—on
the job, because the outlook for viewing
HD content on a PC screen is
cloudy: While a few monitors sport
the HDMI (High Definition Media
Interface) connectors seen on the latest
HDTV sets, Microsoft’s upcoming
Windows Vista won’t show HD video
on even brand-new PCs and monitors
unless they pair DVI or HDMI with
the HDCP (High-bandwidth Digital
Content Protection) technology that
Hollywood invented to prevent copying
or downloading music or movies
… or moving content you’ve paid for
from one playback device to another.
Speaking of bandwidth, the largest
LCD monitors, such as Dell’s and
Apple’s 2560 x 1600-pixel whoppers,
require an extra-powerful card known
as a dual-link graphics adapter, with
512MB of display memory if possible.
ATI’s FireGL V7350 PCI Express workstation
adapter has 1GB of onboard
memory and can drive two of the
abovementioned monsters or one
immense 3840 x 2400 display.
Don’t confuse dual-link graphics
adapters with dual-head adapters that
can drive two monitors simultaneously.
The latter can also be accomplished
by installing a second or third
graphics adapter, or even by plugging
in a device from Tritton Technologies
called the See2 USB 2.0 adapter. This
gadget performs the remarkable feat
of turning a Windows PC’s USB port
into an additional VGA port, although
its resolution and speed limitations
restrict the second display to the
convenience of holding your e-mail or
web browser while your design work
fills your primary screen.
