What is the advantage of a 120hz lcd tv over a 60 hz lcd tv?

Answer 1

Television signals are broadcast at 60Hz, that is 60 fields every second. To make movement appear smoother and to reduce flicker on televisions, some models refresh the screen at twice or four times the rate of the incoming signal. Theoretically, the faster the refresh, the smoother the image will appear so 240Hz might be considered better than 120Hz.

But, it's not quite that simple. Some people prefer this processing while others will say that it does not benefit the quality.

Increasing the frame rate is not a simple task. Each additional frame needs to be created by examining the frames before and after with all movement predicted and calculated. It takes a lot of processing power to do it properly and the image processing still gets it wrong sometimes. The result can be smearing of the image or even adding some high speed jerkiness. These processes can never create information that was not captured originally so the end result always adds errors. Whether the end result appears better, worse or just the same is always a matter of opinion. Get into stores and see for yourself. If you like the effect of 120Hz or 240Hz refresh, it's a good thing to have. If you don't, then it's not worthwhile. If you are buying, remember it's your television so like what you like and not what you are told to like.

Answer 2

The refresh rate of a broadcasts signal is either 30Hz or 60Hz (In Europe is it 25Hz or 50Hz). This is the number of time each second the image is refreshed.

Some televisions use a processor to create intermediate images in an attempt to make the image smoother that the native refresh frequency. Add one frame between each of the original frames and you have have 120Hz refresh. Add another between each of those frames and you have 240Hz.

Whether or not it actually improves the image is a matter of opinion. The created images don't add more detail to the moving image because they are calculated and not captured from the original scenes.

Before investing in a television with high refresh rates it is well worthwhile looking at it to make up your own mind. Different brands perform in different ways so always make sure you can see an improvement before spending the extra money.

Answer 3

LCD TVS with 120hz displays show action in a clearer manner than displays with 60hz.

Answer 4

The 120hz set would be the better choice.
