What does the Hertz (Hz) designation in LCD TV specs mean?
by

1 Answer

Answer :

The refresh rate of the picture; as the screen is “drawn”, the pixels are refreshed a certain number of times per second, thus refresh rate. Rate is measured in “cycles per second” and the abbreviation for this is Hertz (or Hz for short). Although most video has a frame rate of 30 times (images) per second, the pixels are “charged” with information more times than that, which presents a crisper and more accurate image to the eyes. It is said with higher refresh rates, there are less chances of visual artifacts when objects move quickly through the picture. Sometimes quick pans of the camera will cause flicker on the screen, or distortion where objects appear to bend when the camera pans from one side to another. This can also be a property of the camera type, as some camera technologies suffer from refresh issues when acquiring the image (CMOS sensors in particular).
