Are you looking to buy a new TV in this
video everything you need to know before
buying a new television
nowadays the amount of screen sizes
available is outstanding from 14 inches
to over 100 inches so how do you figure
out the right size for you according to
THX you should divide the diagonal width
x 0.8 4 inches this will give the result
of the ideal distance between you and
the screen using this method if you get
a 65-inch TV you should sit around 6.5
feet from it another calculation you
could try as a seating position between
one and a half or two times the diagonal
width of your screen using this approach
a 65 inch screen would work for a
viewing distance between 8.1 and ten
point eight feet but if you want you can
try the viewing distance calculator you
find the links in this video description
below if you one of those who think this
will work for you there are a few things
to consider first remember that the TV
will be right up flat to the wall so you
might want to go up a screen size or two
second many TVs don't ship with wall
mounts included so look for a TV with
wall mounts crew positions compatible
with the vassar industry standard and
another thing to keep in mind is the
viewing angles especially vertical
viewing angles if you are planning to
mount your TV near feeling or above a
fireplace something typically not
recommended there are two types of TV
technology LCD and OLED and both are
important variations on the LCD industry
LCD LED TVs use panels of liquid crystal
pixels illuminated by external light
sources the advantage of LCD TVs are the
brightness the affordability and
durability their main disadvantages are
limited viewing angles and difficulties
controlling light in the picture there
are two types of LCD panel IPS and VA
IPS are predominantly made by LG
display's feature and LG LCD TVs and
also in some usually affordable models
from other brands VA panels are more
widely used and
made by a variety of manufacturers IPS
panels offers slightly wider viewing
angles than VA panels but struggle with
contrast on the other hand VA panel
feature narrower viewing angles but
generally produce much better contrast
OLED TVs use a system of organic foss
foss that enable each pixel to generate
its own light this allows a superior
contrast and like precision than you can
get with even the most advanced LCD TV
olaide TVs can be watched from much
wider viewing angles than LCD TVs
without color or contrast reducing
however there are also issues with an
OLED TVs they're still substantially
more expensive and old lade TVs
currently can't get nearly bright like a
LCD TV something that could become an
issue with HDR content if you want to
buy an LCD TV the key point to consider
is how the panel is lit because this has
a great impact on the screen contrast
some panels use lights mounted on the
edge of the screen edge-lit panels while
others use lights mounted directly
behind the screen generally speaking tvs
with lights behind the screen deliver
better contrast than edge-lit models but
these models don't generally feature
such slim designs tend to cost more and
often consumes more power other option
to consider with LCD TVs is local
dimming this can dramatically improve
contrast these days main connections are
HDMI USB ports and multimedia support
with HDMI try to get at least three and
with 4k TVs try to get the TV with the
2.0 rather than 1.4 HDMI version USB
ports are useful for both playing back
multimedia look for at least two I
dearly three but keep an eye on the USBC
type it will be a stander soon most TVs
have built-in Wi-Fi and ethernet ports
so that you can connect them to the
internet
curb TVs are much less common in 2017 if
you are looking to buy a very large TV
or you're going to be sitting pretty
close to your screen a curved screen can
make a slightly more immersive
experience curb screams follow the shape
of your eye making the corners of the
picture look sharper than they do on a
flat TV and also curved screen loose
less color and contrast when viewed from
an angle however there are issues first
they tend to distort any on-screen
reflections second if you watch from an
angle of really much more than 20 to 25
degrees the picture can start to look
shortened and finally if you are not
feet in the optimal position if you're
either too far back or off to the side
curved TVs can distort the pictures
geometry high dynamic range HDR TVs are
able to produce pictures that contain
much more brightness and contrast than
normal TVs as long what you watching
contains HDR luminant data all current
HDR TVs also support wider color
spectrums often described as wide color
gamut all wcg currently there are three
types of HDR HDR 10 is the industry
standard and all he be supported dole
division adds an extra layer of
information that tells a TV how to
render pictures are themed only some
brand like LG Vizio TCL and sony support
this and there is also hybrid log gamma
that was designed for HDR broadcasts
some LCD TVs usually high-end TVs have
started to use this technology
quantum-dot technology delivers wider
color ranges than you can get with
normal LCD panels quantum dots of tiny
particles from two to ten dena meters in
size with each size capable of emitting
a different color avoiding color filters
and white LED backlights two things that
typically limit an LCD TV color
performance quantum dot Phoebe's are
generally markedly more expensive than
normal LCD TVs and samsung is still a
biggest reliable man you
actor in this quantum door technology
with its 2017 models but there are
alternatives to quantum dots when comes
to expanding cover range triluminos
models from Sony use wide range fossils
and LG with nano selves in its high-end
TVs screen brightness as measured in
midst and with many HDR proponents
including Dolby vision we are enter on
an it race where TVs all push to get
brighter and brighter the brightest LCD
TVs samsung's upcoming q LED models can
get as bright of 2,000 myths the 2017
generation of OLED TVs are recognized to
get to between 800 and 1,000 myths
contrast ratio is basically a
calculation of the difference between a
screen deepest black and brightest wives
written for instance as 10,000 to 1 but
now few TV brands are quoting contrast
ratios the sound quality of the flat TV
can vary greatly this is something that
you should pay attention if you do not
intend to use an external sound system
look how many speakers a TV has and its
configuration for instance a two to one
configuration would indicate two stereo
main speakers with one dedicated bass
speaker or a three to one configuration
that would point to a dedicated center
or dialogue channel alongside stereo and
bass speakers sub woofer speakers for
bass are always welcome because is known
how much TV speaker suffers from lack of
lower end sounds another audio issue is
lack of space available to speakers and
thin TVs meaning they usually have to
expel their sound downwards tvs that
manage to provide forward sound results
in a much cleaner and more powerful
sound another warning of Stevie's that
offers DTS or dolby digital surround
decoding no TV can deliver anything
close to a proper surround sound from
its own speakers the best solution here
is to use actual rear speakers
especially with a sub woofer to add bass
today almost every day we can connect to
a network enabling the use of online
features or to access media files stored
on other devices such as cell phones
tablets network attached storage etc but
in reality the quality of such smart
features can vary greatly don't be
seduced by appt quantity the vast
majority of DV apps are pointless
quality is much more important in fact
for many the only online feature that
really matter are the online streaming
services especially amazon prime Netflix
and catch-up services for your regions
broadcasters finally the simplicity of a
smart TV interface will rule and how
much you might use it currently LG's
webos and Panasonic's home screen
systems handle their content most
effectively I'd like to thank you for
watching and if this video was useful to
you subscribe to this channel that I'm
sure you already did and I'll see you in
