The reciprocal number of a horizontal cycle is called horizontal frequency. Horizontal frequency is measured inkHz.― Vertical FrequencyRepeating the same picture dozens of times per second allows you to view natural pictures. The repeat frequency is called "vertical frequency" or "refresh rate" and is indicated in Hz.― 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 monitor (connected to a PC) for an LCD monitor. If the LCD monitor does not support 85 Hz, change the vertical frequency to 60 Hz using the CDT monitor before you exchange itwith the LCD monitor.
