10.3 Standard Signal Mode Table

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. Therefore, 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 the screen size of 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 it with the LCD monitor.
