Here are some buying tips that are often times overlooked, but very important in the purchase of a Television, whether it be a small LCD/LED TV for the bedroom, large screen Plasma or projection TV, or the latest Internet-enabled or 3D TV.
1- Picture Quality
Darkness of Picture Tube or Screen Surface: The first factor is the darkness of the picture tube or screen. With several televisions turned off, check the darkness of the picture tubes and screens. As Like Videocon Lcd/Led ,The darker the screens, the better the TV is at producing a high-contrast picture. A TV cannot produce blacks that are blacker than the tube or screen itself. As a result TV’s with “greenish” or “grayish” looking screens produce low contrast pictures.
One the other hand, if you are considering a video projector, projection screens are white, instead of black. In this case you need to purchase a screen with high reflectivity as the image is reflected off the screen to the viewer. Although the brightness and contrast performance of the video projector mainly lies with the internal circuitry of the video projector itself, a screen with low reflectivity will dampen the viewer’s experience.
2- Scaling: With the advent of HDTV, scaling ability is also an important factor to consider when buying a TV. To be frank, analog video sources, such as VHS and standard Cable, do not look as good on an HDTV as they do on an analog TV.
Scaling is a process where a TV or DVD player tries to eliminate the defects in a standard resolution video image to make it look better on an HDTV, but not all HDTVs perform this task well. Also, even with the best scaling capability , you cannot magically transform a standard resolution image into a true high definition image.
So, when considering an HDTV purchase, also look at how well the TV looks with both high definition and standard definition content. See if you can get the dealer to show some standard definition content on the TV before you buy it. Also, as the screen size gets larger, the quality of a standard definition image keeps going down. Don’t expect your VHS tapes or standard Cable signal to look very viewable on a screen larger than 50-inches unless you have a long screen to seat viewing distance.
3- Audio Capability/AV Inputs and Outputs
When watching television we often times forget about the quality of the sound, because we are concentrating on visual experience. With more and more consumers integrating televisions into their stereo and home theater systems, the ability for a TV to provide more in the audio area is becoming more important. When looking for a television, make sure you look behind it as well as in front of it. Even if you aren’t planning on hooking the TV up to an audio system soon, give yourself some flexibility.
Check to see if the TV has a least one set of audio/video inputs and one set of audio outputs. On the input side, check for RCA-composite, S-Video (being phased out on many TVs), and component video inputs. If you are going to use the TV for HDTV applications, check for component (red, green, blue), DVI-HDCP, or HDMI inputs for attachment of HD-Cable/Satellite Boxes, Blu-ray Disc players, Game Systems, and HD Network Media Players/Streamers.
In addition, most DVD players and all Blu-ray Disc players have HDMI connections. This allows the viewing of DVDs in an upscaled, HD-compatible format, or high definition Blu-ray, but only if you have a television with either DVI or HDMI inputs.
As an added bonus, most televisions now come with a set of audio/video inputs in the front or side of the set. This can come in handy for hooking up a camcorder, video game console, or other portable audio/video device. Also, a growing number of TVs also have Ethernet connections, or built-in WiFi, for accessing a home network and the internet.
Simply put; even if you don’t have all the latest gear to hook up to your television, get a TV has enough input/output flexibility to add future components of various types.
If you are considering the purchase of TV that offers 3D viewing capability (all 3D TVs can also be used for normal TV viewing as well), be aware of the two important factors.
First, be aware of the two types of 3D glasses that are available:
Passive Polarized glasses that look and wear much like sunglasses. TVs that require this type of 3D glasses will display 3D images at half resolution of a 2D image.
Active Shutter glasses, which are slightly bulky, since they have batteries and a transmitter that synchs the rapidly moving shutters for each eye with the onscreen display rate. TVs that use this type of 3D glasses will display 3D at the same resolution as 2D images.
Some TVs come with one or more pairs of 3D glasses, or they may be an accessory that must be purchased separately. Active glasses are more expensive than Passive glasses.
Also, be aware that when buying a TV with 3D viewing capability, that you also need 3D source components and content to take full advantage of 3D viewing. In other words, you will need one, or more, of the following: A 3D Blu-ray Disc player, 3D Blu-ray Discs, and/or 3D capable Cable/Satellite Boxand services offering 3D programing.
5- Some Final Considerations
In conclusion, here are some final considerations regarding your television purchase.
Needed Accessories: When buying your LCD/LED/3D television, don’t forget additional accessories you might need, such as coaxial and audio-video cables, power surge protector, and any other items that you will need to make the installation of your television complete, especially if you are integrating your TV with an overall home theater system. Also, if you purchase a video projector, keep in mind that you will have to replace the light source bulb periodically, and to take that cost into consideration as a needed accessory cost down the line.
Extended Service Plans: Consider an extended service plan on a projection television or if the TV is more than $1,000. Although televisions rarely need repair, those repairs can be costly, especially for a CRT-based projection set. CRT projection sets house three projection tubes, one for green, one for blue, and one for red. If one projection tube becomes defective, all three must be replaced to insure the correct color balance. In addition, if you buy a Plasma orLCD/LED television and something happens to operation of the screen, the entire set would probably have to be replaced, as these units are basically a single, integrated, piece.
Also, extended service plans usually include actual home service and may even offer some type of loaner while your set is being repaired. Lastly, many home service plans for projection televisions include a “once-a-year” tuneup where a technician will come out to your home, open the set, clean out all the dust and check for the proper color and contrast balance. If you have invested a lot of money in your projection set, this service is well worth it to keep it top notch condition; if you choose to take advantage of it.
