SUPER RESOLUTION+
Description
With the picture improvement technology that minimizes the degradation of the picture
quality due to enlargement (e.g. blurred focus or unsharpened edges), the resolution is not
compromised, even when the images are enlarged, which guarantees a clear image.

is not recommended to use the function for normal text or for desktop icons.
Doing so may result in unnecessarily high sharpness.
Sharpness

• Offset: as a reference for a video signal, this is the darkest color the monitor can
display.
DFC

NOTE
yy Vertical Frequency: In order to display an image, the screen must be refreshed dozens of times per
second, like a fluorescent lamp. The number of times the screen is refreshed per second is called
vertical frequency, or refresh rate, and is represented by Hz.
yy Horizontal Frequency: The time it takes to display one horizontal line is called the horizontal cycle. If
1 is divided by the horizontal interval, the result is the number of horizontal lines displayed per second.
This is called horizontal frequency and is represented by kHz.
