Complete guide for buying a TV

Your complete guide for buying a new TV.

LED TV or LCD TV

First of all you should clear that LED televisions are really LCD televisions that use LED lights for back lighting mechanism instead of the fluorescent CFL lighting mechanism which is used in LCD type of televisions. Both LED and LCD TVs use same LCD (Liquid Crystal Display) technology as far as front panel is concerned.

LED vs CCFL Back light

Traditional LCDs use thin fluorescent tubes called as CCFLs, for the backlight. Contrast levels and black levels are better in LED back light mechanism. Also LED-backlight is a replacement for the uniform CCFL backlight that gives a LCD TV its brightness. So when you are concern about brightness, contrast and black levels, recommend you to check quality of both the TVs in showroom.
LCD TV buying guide
There are two types of LED back light mechanism used in LED type TVs edge-lit and full array. In edge-lit LED LCDs, the LEDs are along the edges of the screen, firing toward the center of the TV. As the LEDs are at the edge, it makes the LED tv extremely thin which is added advantage to people who likes thinner panels.
Full array LED LCDs are arrayed across the back of the TV. As large number of LEDs are required, these TVs are costlier than the edge type LED TVs.

So without going into details of back lighting, if you have option of buying TVs with CCFL back lighting , Edge lit back lighting and full array back lighting.

If you find no much gap between LCD and LED TVs and you have budget for buying the LED TV, then you should go for LED TV which are normally edge lit LED TVs. Full array back light LED TVs are expensive but they offer overall great performance.

Summary

Cost Effective : LCD TVs
Thinner and slightly better picture quality (confirm in showroom) : LED TV (Edge Lit)
Overall best performance : Full array LED back light LED TV.

Note that LED TVs are more energy efficient than LCD TVs.

Selection of screen size

Selection of screen size is also confusing because size you have seen in TV show room may not fit your living room. If you are going to watch the TV from 5 feet to 8 feet then you can go for 32 – 37 inch TVs . If the distance is 10 to 14 feet then go for 42-46 inch display.

Full HD or HD ready

The terms Full HD and HD ready actually refers to the picture clarity of the TV and depends on the resolution which is measured by the number of pixels.
Full HD TV Vs HD Ready
Full HD offers 2 Mega Pixels (1920 x 1080) resolution. The higher the number of pixels, the better the resolution , the better you can see finer details in the TV.
HD Ready offers 1 Mega Pixel (1366 x 768) resolution which is slightly less clear than full HD.
Buying Full HD TV makes sense because now a days many places you can see sue of high definition and in future there will be only high definition signals or picture formats.

3D or 2D

3D TV or 2D TVI think we are not ready for 3D yet, though 3D offers depth to the content you watch, there are some things which needs improvements such as price difference and the content availability. I think for now you can rest for 2D unless you are avid gamer or you must need to watch 3D content on small screen.

Port Connectivity

Apart from HDMI and USB, you must also check whether you can connect home theater system to the TV and how to connect it. Also make sure that these ports should be located on sides rather than back of the TV.

Contrast and brightness

Contrast ratio is the degree of variation of the whitest and darkest parts of the image is very important because it really adds major portion of picture quality. Low contrast ratio normally often results in dark images looking gray and light images more light. While checking for contrast ratio you should look for static and native contrast ratios. Also make sure you have sufficient brightness such as around 550 cd/m2.

Viewing Angle

Viewing angle is the most important factor while buying a TV because one needs to view images clearly on an LCD TV from the sides as well as from the prime viewing area. So make sure you have complete Viewing angle.
