Selecting a supported display mode
The display mode of the monitor uses is controlled by the computer. Therefore, refer to your
computer documentation on how t o change display modes.
The image size, position and shape might be changed w hen the display mode changes. This is
normal and the image can be re-adjusted using automatic image setup and the image controls.
Unlike CRT monitors, which require a high refresh rate to minimize flicker, LCD or Flat Panel
technology is inherently flicker-free.
Note: If your system has previously been used with a CRT monitor and is currently configured
to a display mode outside the range of this monitor, you may need to reattach the CRT monitor
temporarily until you have re-configured the system; preferably to 1920 x 1080 at 60 Hz,
which is a common display mode.
The display modes shown below h ave been optimized at the factory.
