Response time 8 ms gray to gray in Normal mode
5 ms gray to gray in Fast mode
4 ms gray to gray in Extreme mode*
* The 4 ms gray-to-gray mode is achievable in the
Extreme mode to reduce visible motion blur and
increased image responsiveness. However this may
introduce some slight and noticeable visual artifacts
into the image. As every system setup and every
user’s needs are different, we recommend that users
experiment with the different modes to find the setting
that is right for them.
