LCD TV Buying Guide

LCD TV Buying Guide

Deciding Required LCD TV Size

  • Decide the location where you wish to install your LCD Monitor.
  • Measure the distance of  your sitting position to the LCD Monitor.
  • Divide the distance value (in inches) by 3. The resulting number (in inches) will be the ideal screen size for you to purchase.

For Example:

Distance Measured = 10 feet (120 inches)

Ideal Screen Size = 120/3

=    40”

So in this case, a 40 inch screen will be the ideal size of an LCD TV.

Viewing Distance from LCD TV

Screen Size (in inches)

Viewing Distance (in feet)


2 ~ 5


2.5 ~ 5.5


3 ~ 6


3 ~ 6.5


4 ~ 8


4.5 ~ 9


5 ~ 10


5.5 ~ 11

  • If you are using a 3D LCD TV, you need to sit 2 times the distance away from the LCD TV’s width.


Considering Features

  • Ensure that the product you are going to purchase has enough input methods supported.
  • Ideally purchase an LCD Monitor with a Broadband Connectivity feature. This is because, in the future you may require to connect your TV to your home network to browse the internet, watch videos or  install new games.
  • Slots must be available in the LCD,  for connecting a USB, Digital Memory Card, Camcorder or Digital Camera as an external memory device.
  •  Your TV should be easy to use and the provided guide manuals and on screen help should be easy to understand.

Different TV Standards Resolution

1280 * 720p




852 * 480p




480 lines



Selection of Image Quality

  • LCD Monitors are popular for better image quality. Two very famous HDTV standards are 720p and 1080p.
  • These numbers (720 or 1080) represent the vertical pixels number.
  • The screen resolution for 720p and 1080p are 1280*720 and 1920*1080 respectively.
  • For watching movies 1080p HDTV should be preferred for purchasing.
  • For casual use, such as for use in kitchen or bedroom 480p or 720p display will be a great choice.

Selection of Display Type

  • DLP (Digital Light Processing) technology is used in projection monitors. DLP are used for rear and front projections as they produce vivid colours and deep blacks.
  • Plasma displays produce rich colours and deep blacks making them the best choice for achieving greater performance in light-controlled or darker rooms.
  • LCD (Liquid Crystal Display) offer anti-glare screens and vibrant images giving excellent results in brighter rooms. LCD Monitors consume less power than the DLP and Plasma TV.
  • LED (Light Emitting Diode) is another type of LCD TV. In LED Monitors, the LEDs are used for back light.  Usage of LEDs makes them less power consuming.

Aspect Ratio

  • The width to height proportion of a TV Monitor is called the Aspect Ratio.
  • Standard aspect ratio for televisions is 4:3, which corresponds to 3 inches of height for every 4 inches of screen width.
  • The perfect aspect ratio for HDTV is 16:9.

Aspect Ratio



  • Brightness of the television is defined as the emitted luminous power over a specific area.
  • Brightness is measured in  candela per meter square.
  • Brightness is the very important aspect of LCD TV performance. The higher the brightness, the better the picture.



Contrast Ratio

  • Contrast is the ratio between light intensity of the brightest and the darkest points in a picture.
  • Higher contrast ratio makes viewing darker point better and increases picture quality.

 Contrast Ratio


Response Time

  • Response time is the speed at which TV is able to show full white and then full black and then back again.
  • Response time is measured in mille seconds (ms).
  • Minimum response time will ensure better image quality and less streaking.

Response Time


Extra Equipment

  • If you want to hang an LCD Monitor onto a flat wall, you will require a wall-mounting kit.
  • Universal Remote Control is required to control LCD TV’s menu at limited remote locations.
  • A/V cables are required for connecting external sound systems or other multimedia sources.
