Preset Timing Modes - Samsung OH65F User Manual

– Horizontal Frequency
The time required to scan a single line
from the left to the right side of the
screen is called a horizontal cycle.
The reciprocal number of a horizontal
cycle is called horizontal frequency.
Horizontal frequency is measured in
kHz.
– Vertical Frequency
The product displays a single image
multiple times per second (like a
fluorescent light) to display what
the viewer sees. The rate of a single
image being displayed repeatedly per
second is called vertical frequency
or refresh rate. Vertical frequency is
measured in Hz.

Preset Timing Modes

― This product can be set to only one resolution for each screen size to obtain the optimum picture quality due to the nature of the panel. Using a resolution other than the specified
resolution may degrade the picture quality. To avoid this, it is recommended that you select the optimum resolution specified for your product.
― Check the frequency when you exchange a CDT product (connected to a PC) for an LCD product. If the LCD product does not support 85 Hz, change the vertical frequency to 60 Hz
using the CDT product before you exchange it with the LCD product.
