The LTM405W supports a resolution of 1024X768 which may
not sound like much considering a 19" LCD computer monitor runs at 1280x1024, but compared to
a resolution of 852x480 for plasma, the difference in picture resolution is obvious.
The higher native resolution also makes
for a pretty picture when the Samsung LTM405W is connected to a computer through the built
in DVI port, but more on that a little later in the review.

Terminals: DC power, Coax cable input, S-Video
input, RCA Video input, RCA Left/Right Audio inputs, RCA component inputs
(480i/480p) & left/right audio, and RCA component inputs
(480p/720p/1080i) & left/right audio, a DVI computer video input, PC
audio input, headphone jack, RCA left/right/center audio out, and a set of
wire connectors for the two stereo speakers. Adjacent to the audio/video
connections is a kensington lock hole.

has a pixel pitch of 0.6735mm which may sound extremely large again compared to
current LCD monitors, but compare that to typically just over 1.0mm for an
equivalently sized plasma display and you'll get the picture.
There are also none of the large vertical
black address electrodes lines we find on plasma screens; adding yet another notch to
the "I'm better than you" category for LCD vs. Plasma.
With a brightness value of 500cd/m2 and contrast
of 600:1 the Samsung LTM405W features a pixel response rate of about 22ms, ensuring it
is suitable for fast action flics without worries of ghosting (we didn't see any
during several rounds of DVDs).
Generously wide viewing angles of 170 degrees / 170 degrees keep
the 16:9 aspect ratio 40" screen looking good from just about any angle. Though, in our tests with the Samsung LTM405W we found the image
contrast had a slight tendency to lighten up a little as one moved away from
dead center. With the screen at eye level, a distance of about 10' away, the
picture is quite simply amazing.
The LTM405W display draws 220W of power, with much
of that figure being gobbled up by the large backlights. Comparably, Samsung's 42"
SPL4225 Plasma display, which we reviewed previously here, draws upwards of
310W of power, or roughly 40% more juice. The difference in power
consumption should make environmentalists and penny pinchers happy
With a MSRP of
$16,000CDN ($12K USD), and retail prices realistically more like $8,500CDN ($6K USD), going
'LCD' at this size is not a cheap endeavor. A similarly sized plasma
screen will set you back a heck of a lot
less, but a plasma screen's lifespan can be limited to just 30,000 hours before
luminance begins to degrade.
And while an LCD
television backlight can start to dull after about 60,000 hours of use, the
backlights are separate components which theoretically could be replaced by
qualified service personal. When a plasma's screen begins to burn out there is no
means to repair it.
