*Response Time: The time it takes to switch a pixel off and then on and then off again (or from black to white and back to black). A low response time is desirable for the display of moving images without ghosting. The Response Time quoted for many LCD monitors is specific to transitions from black to white and back again, it does not specify the time required to switch between the many gray levels or colors that make up an image. *Gray to Gray or GTG Response Time: "Real world" video content contains a combination of grayscale images. It generally takes longer for a pixel to transition to an intermediate level of intensity (i.e. a gray or color level) than it does for it to turn completely black or completely white. For example the "Gray to Gray response time" of an LCD panel may generally be 30 to 40 ms while the "Response Time" is 12 ms. Specifications 39

*Response Time: The time it takes to switch a pixel off and then on and then off again (or from black to
white and back to black). A low response time is desirable for the display of moving images without
ghosting. The Response Time quoted for many LCD monitors is specific to transitions from black to white
and back again, it does not specify the time required to switch between the many gray levels or colors that
make up an image.
*Gray to Gray or GTG Response Time: “Real world” video content contains a combination of grayscale
images. It generally takes longer for a pixel to transition to an intermediate level of intensity (i.e. a gray or
color level) than it does for it to turn completely black or completely white. For example the “Gray to Gray
response time” of an LCD panel may generally be 30 to 40 ms while the “Response Time” is 12 ms.
