Buying Guide : Flat Panel Television
http://gadgetsfreeak.blogspot.com/2013/02/buying-guide-flat-panel-television.html
Dear Readers, this time I have researched on how to buy flat panel televisions, and I am sharing my
article on the same, just on the side line, I own, 42 Inch Full HD, Videocon
LCD bought 4 years back.
Now if you have decided to grab a new television, to replace
your old TV then this guide can be useful to you as when you will step in any
store, the salesman will confuse you with many technical jargons which are even
not important to consider while making buying decision.
Confused between LCD / LED /
Plasma???
In LCD TV, the display is powered by Liquid Crystal Display
& CFL bulb, which consumes more power than LED TV, whereas Plasma TVs have
better viewing angle but consumes more power than LED TVs for same size. So if
you want to keep check on power consumption you shall go for LED TV but those
are little bit costlier compared to Plasma & LCD. Power consumption is as
follows…
LED < LCD <
Plasma
Size:- As far as size is concerned, there are many
options available in market ranging from 19 inch to 65 inch, now which size to
prefer, there is standard formula for it.
If your viewing distance is 5 feet = 60 inch, than minimum
size of TV you shall take is 60/3 = 20 Inch and at the max you can go for
60/1.5 = 40 inch.
You can calculate as per your viewing distance, viewing
distance is considered between your sofa / couch to the place where you want to
place your TV.
Now say if you are choosing TV for your bedroom then you can
go for minimum size but if you are choosing TV for Living room or Hall you can
go for anywhere in between to min & max TV size, depending on your budget.
Thumb rule is “bigger is better”, depending on budget as
larger screen size will cost you more.
Dynamic Contrast Ratio:-
This is the term that you will come across while checking
any TVs specification, and varies from 100000:1 to 1000000:1 now a days. Every
company has different measurement method to measure these contrast ratios, so
you can’t judge different set of televisions by merely reading the contrast
ratios specs, better is to go to store and compare with your eyes only.
Previously there were only static contrast ratio only but now a days tv manufacturers trick ( read
dimm the light / switch off the light in the areas where black picture has to
be shown) the LED / CFL lights in the panel to generate more contrast while
displaying black color scene on display panel.
So this one is really tricky and not to give much importance
if you feel that you like a TV set which has laser Dynamic Contrast ratio than
the one shown by sales person!
HD Ready / Full HD:-
A television set which has inbuilt HDTV tuner is called Full
HD TV, and the one which requires external tuner such as HD SET TOP BOX is
referred as HD ready.
In simpler terms Full HD TV will be able to receive HD
signal on its own directly from air, like we receive DD from antenna, however
no channel in India
is transmitting over the air HD broadcast.
Whereas for HD ready television to display HD content, you
need to connect external HD sources like any DTH company’s HD set top box.
Considering scenario in India
you can go for HD ready TV also, because in India as of now HD broadcast is
available thro DTH operators only. But if budget is not constraint one shall go
for Full HD. For 32inch TVs price difference in HD ready and Full HD tv is
hardly Rs 2000 to Rs 3000 only but larger the screen sizes bigger the
difference is!!!
Refresh Rate:-
As we know that, television is a series of images, shown
rapidly enough that your brain sees it as motion, now in old LCD television
quite a few years back while watching sports you must have observer spot of
colors moving along the image creating blur, this is because pixels in the
screen where not able to respond at the rate the images move in program, and in
old television sets, in one second each frame is shown for 60 times, resulting
in blurs.
To avoid this blurring of image while watching sports of
fast moving programs such as car / bike races, tv manufacturers came with idea
to show each frames at least 120 times in a second resulting in 120Hz refresh
rate and the blur was gone.
This was basic, now 120Hz refresh rate is enough, now a days
many manufacturer offer rates beyond 240Hz which is not required as our eyes
will not be able to distinguish the images from 120Hz and 240Hz so better to go
for a TV with 120Hz refresh rate and obviously this will save some of your
money also!!!
Now these were the some of the sepcs which one shall look
for before making buying decision.
Apart from this
important checkpoints are like, does it have HDMI ports, USB plug n play option
or not?
Now a days it is necessary to have at least 3 HDMI ports,
one for HD Set top box, one for Blu ray player, another HD for gaming console.
Base on your need you can go for 2-3 HDMI port TV.

ReplyDeleteIt is helpful JIgnesh Bhai
ReplyDeleteI heard that some people have complained that LED me Pixels break hoti hai. IS it right?
Nope! Pixels don't break, after certain hours of usage, they go dead, but now a days almost all LCD / LED / Plasma Panels will give you viewing hours of 50K - 60K hours, after 70% usage there will be de-coloration.
DeleteThere are certain techniques available on net to recover the dead pixels, it is better ask / check for warranty against Dead Pixels as well as none of the manufacturer will mention it.
This is really good info at expert level. It would be great if you can elaborate on more specs like, audio and video features, 3D sound, viewing angle, etc.
