Screen size is the most notable feature of the TV but you should not
focus on this alone. The LCD TV and the plasma TV are older display
technologies now. The LED TV, and OLED TV are more current.
Thin is in and the LED backlighted LCD TV is super thin. The OLED TV is even thinner.
Samsung
and Panasonic are the best rated TVs with Sony, Toshiba, Vizio, LG
and Sharp also offering quality products.
High definition TVs are generally from 26 inch screen size to 32, 40,
46, 50, 55, 65, 70, 85 inch screen sizes and more. The 40 inch to 55 inch
screen sizes are best for living room while 32 inch is best for
bedroom.

HDMI - get a TV with several HDMI inputs as this is the connection of
choice. At least 4 would be good but 2 minimum.
Refresh rate - 60Hz is minimum with 120Hz better and 240Hz excellent.
PC Input - Most HDTVs have an input for connecting your computer, both
video and audio.
Internet Ready - Many HDTVs today are capable of connecting to the
internet. An RJ-45 jack is required plus firmware or some of the newer
TVs have Wi-Fi built in.
Most HDTVs have built-in tuners for over-the-air digital TV broadcasts
(ATSC), analog TV signals (NTSC) and cable TV (QAM). For cable TV, you
will need a decoder box if your cable TV provider scrambles any
channels. Otherwise the QAM tuner will allow analog/digital channels to
be viewed.

| Resolution,
or picture detail, is the main
reason HDTV programs look so good. The standard-definition
programming most of us watched for so long on our analog TV sets, has
at most 480 visible lines of
detail, whereas HDTV has as many as 1,080. There are three common HDTV
resolutions, called
720p, 1080i and 1080p. One is not necessarily better than the other;
1080i has
more lines and pixels, but 720p is a progressive-scan format that
should deliver a smoother image that stays sharper during motion.
At the top currently is 1080p, which combines the
superior resolution of 1080i with the progressive-scan smoothness of
720p. True 1080p content is rare outside of Blu-ray and the
latest video games and none of the major networks has yet announced
1080p broadcasts. Look at the comparison chart below to see the
differences. |

The true industry standard for 4K is 4096x2160 - 4096 pixels of vertical resolution to 2160 pixels of horizontal resolution.
4K also uses JPEG2000 compression and supports bit rates up to 250Mbps (megabits per second).
UHD (Ultra High Definition) is the successor of Full HD and doubles the resolution from 1920x1080 to 3840x2160.
Full Ultra HD, sometimes called 8K, refers to a resolution of 7620x4320. This is quadruple the pixels of 4K and sixteen times larger than Full HD.

Native Resolution
Every HDTV has a native resolution. Native Resolution is the number of
physical pixels in a display device. For example, an XGA display has a
native resolution of 1024 physical pixels of resolution horizontally
and 768 pixels vertically or 786,432 total pixels.
An HDTV with a native resolution of 1,920 by 1,080 can display 1080p
video sources without any "scaling" or video manipulation. An HDTV with
1,366 by 768 native resolution would have to modify the original 1080p
source or "down-scale" in order to display it. The point here is that
you want your HDTV to have a native resolution as close as possible to
the video sources you are going to be viewing. HDTVs will up-scale or
down-scale video to match native resolution without any problem,
however you want your viewing to be as pure as possible. You can check
the HDTV you plan on buying to see what the native resolution is by
looking online at sites that sell that model, at the owner's manual or
on the manufacturer's website. Sometimes a retail store will list the
native resolution of HDTVs they have on display.
HDTV FAQ
Q: I bought an HDTV to replace our old analog TV. We had cable TV with
a box. Do I need a new cable box?
A: Yes. You need a digital cable box and make sure it is HD. Look for
the HDMI jack on the rear panel of the box. Call your cable TV provider
to be sure you have everything you need for HD. An HDMI cable from the
box to the HDTV is needed.
Q: Is DVD high definition?
A: DVD gives you very good video resolution but it is not HD. For HD
you need to move up to Blu-ray Disc movies.
Q: Can I connect my VCR to my HDTV?
A: Yes. VHS (or Beta) tapes will not give very good video resolution
but they can be viewed.
Q: Do I need to buy an hdtv antenna for local TV stations for my HDTV?
A: No. There is no such thing as an hdtv antenna. HDTV signals are
broadcast using the same VHF and UHF frequencies as the old analog TV
system. If you have a good VHF/UHF TV antenna and live in a major metro
area, you should have no problem getting HDTV signals with your
existing antenna.
Q: After I buy an HDTV do I get all high-definition TV shows?
A: No. You need to upgrade your cable
or satellite TV package to include HD service and get an HD box/decoder
(which may increase your
monthly bill). Without an upgrade, you may only be able to watch
standard-definition programming from cable or satellite. Ask your
provider for details and costs. You will however be able to get
broadcast (over-the-air) HD programs.
Q: After I add HD service, will all my channels be in HD?
A: No, you will have both HD and standard-definition channels to choose
from. You should notice a significant difference in picture quality
when switching between the two. Within some HD channels, not all
programs have been recorded by HD cameras.
Q: Will all programs be in widescreen once I have HD?
A: Not necessarily. HD programming should automatically appear in
widescreen format. However, standard-definition programs may appear in
the square 4:3 box you were used to seeing on your old tube TV. You can
adjust your HDTV's aspect ratio settings and stretch an 4:3 image to
fill the screen but you may get distortion.
Q: What Is Internet-Ready HDTV?
A: Internet-ready HDTVs take the web content that has become
increasingly popular and deliver it directly to your television. These
televisions are equipped with an Ethernet port (and often a wireless
connection or add-on) much like your PC or other network devices. Once
connected to your router, they use your broadband Internet connection
to provide you with content. Content varies depending on manufacturers
and models, but you can gain access to streaming video and music
services (both paid and unpaid), smartphone-like applications or
widgets, social networking tools, online photo galleries, and more.
Manufacturers continue to expand their offerings and can extend their
devices' abilities via firmware updates.
Q: Can I Surf the Web on My Internet-Ready HDTV?
A: No. Most of these devices don't feature Internet browsers, so you
can't simply surf the web as you would on a PC. The current exception
is Sony's Internet TV Powered by Google TV, which does allow users to
surf the Web while watching TV.
The current focus of Internet TV is on streaming media--along with
pared-down versions of popular web applications, for quick access to
information you want to check regularly.
Some applications provide a fully interactive experience. You can, for
example, view your Flickr or Picasa slideshows, update your Facebook
status, or perform other similar actions, but you can't pop open a
browser and search for general web information.
Q: What are my Costs in addition to the Internet-ready HDTV?
A: Internet service and home network costs. This includes the cost of
monthly broadband Internet service, a router for distributing your
Internet connection among your different connected devices, cabling or
optional wireless hardware, and, finally, the cost of any paid services
(such as Netflix or Vudu).
Q: Is the HDTV as Fast as My PC?
A: The answer to this question would depend upon the specific TV and PC
being compared, but in general Internet TVs are not as powerful as
modern PCs that are designed for more demanding processor tasks.
Q: Is There HD-Quality Internet Content?
A: YES. Video can be streamed in full 1080p resolution with services
like Vudu or Netflix (although resolution and compression may be
adjusted for slow Internet connections).
Q: How Do I Navigate Internet Content on My TV?
A: The means of navigation depends upon each television's manufacturer
and model. Nearly all units include a remote control for accessing
content, including input of alphanumeric characters. Vizio provides a
Bluetooth remote with a slide-out QWERTY keyboard for several of its
models--similar to certain cell phone designs. Other models even allow
you to attach a USB keyboard, such as Panasonic's TC-P46G25.
Q: What's the Difference Between Internet Television and Internet
Protocol Television (IPTV)?
A: The main difference between these two means of delivering content is
that Internet TV is delivered over the Internet—the global,
public World Wide Web—and IPTV is delivered over a private
managed network (by a telecom company, for example).
IPTV requires a set-top box, and viewers receive the provider's own
channels--it is being deployed by telecom operators as an alternative
(or addition) to cable/satellite television. The benefits are
interactivity with the quality, consistent service, and added security
of a private network.
Internet TV's advantage, however, is that publishers can deliver their
content to any number of devices without being tied to a specific
service provider or system. For example, Netflix can be streamed to
Internet TVs, Blu-ray players, video game systems, etc., regardless of
manufacturer, and which company is providing broadband service.
Q: What Can I Expect to Get in a TV That's Internet-Ready? Does It Come
with a Computer Inside It? A Keyboard? A Mouse?
A: Generally, on the outside, an Internet-ready TV will look the same
as a standard HDTV, aside from the Ethernet port for connecting to your
network. While you won't see too many keyboards or mouse peripherals,
some models do feature different controls than their non-Internet
equivalents, such as Vizio's Bluetooth QWERTY remote mentioned above.
Others may include an external dongle/piece of hardware for a wireless
connection. But these are not all-in-one computers: one might think of
them as enhanced televisions offering a handful of entertainment
bonuses on top of all the other modern HDTV features.
Q: What Do I Need to Connect My TV to the Internet, Wired or Wirelessly?
A wired connection requires the following:
1. A broadband Internet connection (with modem)
2. A router connected to your modem
3. An Ethernet cable for connecting the HDTV
A wireless connection requires a router with Wi-Fi and a means of
connecting wirelessly (this may be built in to the television or the
manufacturer may sell/provide additional hardware).
One additional necessity might be a credit card for handling per-view
or subscription fees on paid services and an Internet-connected PC for
setting up and managing accounts, etc.
Q: How Do I Decide Which TV Is Best for Me?
A: The landscape is changing fast in this arena and it is best to check
with the TV's manufacturer or their website for the latest offerings be
it sports, social, movies or other areas of interest.
Q: How Can I Get the Internet on My TV if I Don't Have an
Internet-Ready TV?
A: Several DVD and Blu-ray players now offer similar services to those
outlined here, and many devices allow you access to particular content
such as Roku's Netflix devices. Another option is accessing content
through video game systems, something many consumers have been doing
for some time now.
Perhaps the most obvious would be simply connecting a PC to your
television. Several manufacturers offer low-profile media PCs these
days that are equally at home in an office or living/family room.
Q: Can I give up satellite/cable TV?
A: You could if you do not want certain programming like pay-per-view,
on-demand or specific event shows. Many TV shows and movies are
available online but this is a personal decision.
