Available Now!
Toshiba already has a range of TVs and
projectors capable of displaying High
Definition broadcasts in all their glory
when they are available. In the
meantime, you can make the most of
the products' high specifications and
their benefits.
High Resolution
The resolution of a screen dictates
the amount of picture information you
will see. The more image data available,
the more detail in the display and the
greater your viewing experience. That's
why all the widescreen LCD TVs in this
brochure have a minimum panel
resolution of 1280 x 720 (almost 1
million pixels). Potentially each pixel
can display different information,
so enhancing the colour, tone and
ultimately, the three-dimensionality of
the image displayed.

Thanks to Digital TV, DVD and High Definition TV, the audio-visual quality of programmes available
is generally far superior to anything we have experienced in the home before. However, you need

to produce a stunning picture by
enhancing four core elements of a
television image:
An industry standard for connecting
high definition components, High
Definition Multimedia Interface™
transmits uncompressed digital video
and audio content over a single cable,
replacing the multiple cables required
with analogue AV connections.
As there is no conversion from digital
to analogue and back again (as with a
SCART lead for example), the original
digital quality is upheld.
HDMI™ dramatically simplifies home
cinema system installation and offers
numerous additional benefits including PC
compatibility, automatic format adjustment,
as well as automatic configuration of the
system to turn on or off the components
necessary to view a DVD, listen to a CD
or watch cable or satellite TV.
What is Real Digital Picture
Processing?
Real Digital adds yet another dimension
to the picture processing technology by
reducing the number of signal separations
that normally occur in an LCD TV.
Signal processing in current LCD TVs
– Using Real Speed
has to pass through numerous separate
signal conversions before it arrives at
the panel processing chip. This process
dramatically reduces the picture signal
quality of the TV.
Toshiba's new Real Digital picture
processing reduces the signal
separation stages, therefore
maintaining the original detail of
the signal, and enhancing the
picture performance.
If the HDMI™ interface is used, the
signal is carried directly to the panel
signal processor as a digital signal,
and no picture separation occurs.
