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.
If a signal that belongs to the following standard signal modes is transmitted from your PC, the screen will
automatically be adjusted. If the signal transmitted from the PC does not belong to the standard signal
modes, the screen may be blank with the power LED on. In such a case, change the settings according
to the following table by referring to the graphics card user manual.
