The main difference between HD televisions and conventional television sets is that they are able to recreate pictures at higher resolutions. In other words, they have more pixels at their disposal. These pixels if compared to those available on regular or should I say a standard definition set with the same dimensions are a lot smaller. The end result is a sharper and more realistic looking picture with less space between pixels.
720p Vs 1080p HD TVs: When Full HD Is Worth It
Learn about HD resolutions and how screen size and sitting distance affect your perception of the quality of the picture.
Hype Or No Hype?
One of the problems of this market is that many consumers do not really understand when it is better to buy a product with a higher resolution and when it would be reasonable to buy one that is not a top of the line product in terms of resolutions and specs but would be a better bang for the buck.
According to statistics on many websites on high definition, many consumers cannot tell the difference between a picture created using a 720p and a 1080p resolution also known as “Full HD”. Hype often leads to compulsive shopping and this is one of the reasons why so many people end up spending on HDTV sets that have a higher resolutions even if they can't really see no improvement. The difference in money that a person could save by choosing a set with lower specs could be used to buy a Blu-Ray player or any other gadget to complement a newly purchased TV.
Looking For a Brand New HD TV?
How come many people do not see this difference while others do?
The answer to this question is a very simple one. It is very difficult to see improvements when changing from a 720p resolution to 1080p if the screen is small or medium sized. For example, when you change from 720p to 1080p most people won't see too much of a difference on a set that has a screen smaller than 36 inches. Some people don't even notice a change that is worth paying more even if the screen measures more than 43 inches but this is more of a personal choice.This is nothing new. The debate between people who can and cannot see a difference still lives after many years in some tech forums as well as if paying more for 1080p is worth the money or not.
The problem is that our eyes have their limits. On smaller screens, the pixels are small enough at 720p to be almost unnoticeable when isolated. If you set up your screen to display only one black pixel on a completely white background using a 32 inch screen it will a little difficult to spot the pixel at more than ten feet. If you do the same experiment using a larger HD television, say a 48 inch one where the pixels are larger, you can spot the black dot with relative ease. If switch the resolution to 1080p then the pixel becomes difficult to spot again.
Remember that the other important factor to consider is sitting distance. The farther from the TV a person is, the more likely the person won't see any improvement unless the unit is large enough. When a person sits close, the difference between resolutions is obvious even if the screen is small. Take where the unit will be placed relative to where you will be sitting into consideration before making a purchase.
