Vision Advice
TV LCD and Plasma
Much has been said about advantages and disadvantages
of these formats. Plasmas have gas changing shape and form continuously while
LCD is made up
of millions of pixels which are stationery in position but
which change colour according to input signal. Plasma have a glass screen which tends to
reflect light if
TV is positioned in front of
window while LCDs do not suffer from this. Plasmas soak up more electricity
than LCDs and tend to run hotter too. Having said that lets get to the picture.
Since LCDs are made up on a grid, pixels sometimes don’t manage to bond
smoothly especially when watching fast
action films and
sports, thus the much talked about term pixellation,
although this problem is being
much solved as technology
advances. Pixellation is more evident on screens larger than 37”. Furthermore LCDs
struggle to reproduce white
and black colours while this is where Plasma excels. This is the
problem which LCDs have to overcome so as to be on par with Plasma in picture
quality stakes. When it
comes to brightness LCD is better than Plasma, so
if planning to install where lots of light enters you Would be better of having
an LCD. Plasma give off their best in dimly lit rooms. Viewing angles on both
formats is not a problem nowadays although on LCD you shouldn’t have screen much
higher than eye level. Running times have gone up 100,000 hours on virtually all panels
thus if you watch TV 10 hours a day you get A life span of 27 Years. When it
comes to colours Plasma offers a
closer to natural picture. LCDs tend to
exaggerate colours which at
first sight look impressive but may tire in the long
run. So to conclude, if you are looking for the best picture quality and going
to install in a dimly lit room than plasma is the one to go for. On the other
hand we would recommend LCD for
a brightly lit
room but only if buying screen up to 37”. Good LCDs bigger than
37” may be found but at very high prices.

What is HD Ready
HD stands for High Definition TV. This has been available in
the USA for
some years now but is only coming to Europe now. Normal TV
be it DVD
or Satellite have a
resolution of 720 X 576 lines. 720 being the horizontal lines and 576 being the
vertical lines. Full HD has a
resolution of 1920 X 1080 lines that
is 2½ times higher than normal TV. Now when
you see a TV that has HD Ready logo on it
this does not mean it has 1920 X 1080 resolution but it can accept it.
The majority of LCDs
available on the market at the moment all have a resolution of
1366 X 768.
Full HD TVs
(1920 X 1080) are available but
are still quite expensive. Having said all of that its
useless to have an HD Ready TV
without having the equipment to extract such an image.
Full HD can only be seen either with an HD DVD Player playing suitable HD recorded films, a Blue Ray
Disc DVD Player Playing Blue Ray
Discs or original SKY ITALIA /
SKY UK satellite set
top box plus some other
providers via satellite.The next thing close to Full HD is an HDMI DVD Player. This converts normal DVD films by means of an upscaler to HD resolution, but
due to conversions taking place by DVD player
and TV picture although of a very
high quality is not as clear and sharp as a Full HD. The quality of these
conversions determines how good DVD player and TV are.
