A word on TV's.

     There are 2 main types of tv's on the market LCD and Plasma. LED, and full array LED will be covered under LCD as they have the same screen.

Plasma
Good points:
Best prices.
Best colour.
Best speed of image and pixel change.
Average life of the TV is 10 to 15 years.

Bad points: 
Very high gloss screen.
Washes out in bright light.
Only comes in 42 inch and bigger.
Overall: 
Plasma uses a gas and some other chemicals to do it colours so it can do every colour of the rainbow, about 3,000,000 on average for shades and colours.  The chemical that gives plasma its awesome colour and speed reacts with light so if it's lower light room buy plasma. Plasma's also are great cabin TV’s as they don't freeze like the LCDs (liquid crystal display).

LCD
Good Points:
It has a low gloss screen. (Unless a high end Samsung)
It comes in smaller sizes.
A little better on the energy bill then plasmas of the same size (~20% less).

Bad Points:
High cost.
Cannot do a lot of shades of colours.
Pixels can't change as fast as plasma.

Overall:
A LCD uses a crystal suspended in liquid and a Cold-cathode lamp (kind of like the long lights used in Wal-Mart’s and other retail places) to make colours kind of like a prism. The spin of the crystal is slow compared to plasma’s chemical reaction so white to black quick changes might be slow enough to see. This slowness can be seen in the tail behind the hockey puck on a fast shot. The crystal only has a set number of colours it can do, about 300,000 colours and shades of colours. This seems like a lot but just look down a line of mixed TV’s and look at the skin tones the plasma will be correct and the LCD will be off trending to white or pink.

Notes on LED:
LED should be written as LED-LCD as it is a LCD screen with a LED (Light Emitting Diode) back light not a Cold-cathode lamp. LED TVs come in two type edge lit and full array. Edge lit uses a ring of LEDs around the outside or frame of the TV to back light it this is not as good as the traditional LCD Cold-cathode lamp. The lamp is brighter and the LEDs if they are cheap will make a blue light which puts a blue/purple shade to the screen. Full Array is the better of the two cause it has LEDs thought out the back so it's just as bright as the lamps of the old TV and they are only found in very high end TVs you don't get the blue/purple colour.

So here's the short of it. Low light buy plasma and high light buy LCD.

First post.

Well I've thought about doing this for a longtime and here goes. This blog will handle common general questions that I run into at work (Tech sales at costco). Keep in mind I'll be dealing with what people can get in St.John's and with normal amounts of money (or whatI would tell a friend to buy).
