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.

- 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.

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.
Brightness
- 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.
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.
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.
