How to Pick Out an LCD Tv?

Buying a television these days is no simple task.  When you walk into a showroom or begin to browse the vast selections online, most of us become overwhelmed by the seemingly endless
choices.  Where do we begin?

With all of the changes in television technology these days, it pays to have a little understanding of the key developments & features before heading out with the credit card.  Below we will attempt to explain the advantages of the LCD technology so that you may be an informed buyer & therefore be happy with your final purchase.

What exactly is a Liquid Crystal Diode?
LCD technology is relatively complex and improving all the time, but is based upon the fact that liquid crystals are in their natural state, twisted. The ability of the crystals to allow light through can be altered by applying electric current. Very simply put, a light source is shone through a liquid containing crystals held between two polarized screens. By applying the correct quantity of light passing through, the desired display is produced.

How does a LCD TV operate?  The Basics:
LCD monitors work by blocking light. By sandwiching a solution of TN liquid crystals between two perpendicularly aligned panes of polarized glass, it becomes possible to manipulate the intensity of light as it passes through this crystalline matrix and out the glass panel at the other end. Depending on the voltage of the electrical charge running through them, liquid crystals will untwist so that the intensity of light able to pass through the second polarized pane is affected. Basically, these displays can switch between light states (where the liquid crystals are fully twisted) and dark states (where the liquid crystals are fully un-twisted), or somewhere along the gray scale in between.

What are the advantages?
- It's easier to watch. Flat panel TV displays like LCDs and Plasmas are significantly brighter and feature higher contrasts than traditional CRT sets. Which means, that an LCD TV will perform exceedingly well under most ambient light conditions. A brightly lit room won't wash out its picture, nor will lamplight cause a glare on your television screen. The beauty of these flat screens is that you don't have to turn out the lights to see the image clearly and easily. Nor do you have to worry about eyestrain, since neither LCDs nor Plasmas flicker the way old-fashioned TVs do.
- The picture is smooth, colorful, and (best of all) wide.
- The display is multi-functional and long-lived.

What to consider before buying?
- Measure your floor plan to ensure that you have enough space.
- Set a budget.
- Make sure that it’s HDTV compatible.
- Do your homework; get to know the product’s features & benefits.

LCDs are all around us. Liquid crystal displays are so prevalent in fact that most people couldn't get through their day without using one. This technology is utilized in digital clocks, microwave ovens, car dashboards, calculators, stereos, thermometers, and even some bathroom scales! The applications for liquid crystal displays are almost limitless, so it should come as no surprise that this technology has revolutionized the most basic home appliance of all-the television set.

BTYahoo home page fails to display Today & Quick Picks?

Using IE7 on both my PC's. The desktop displays the BTYahoo home page ok but the laptop fails to display the Today section and Quick Picks section. IE7 advanced options appear to be identical on both machines.
The Laptop just shows a box with a red x where the two sections should be.

I'm glad it's cleared up. I was about to answer and saw that you already had answered your own question!
