Selecting a supported display mode
The display mode the monitor uses is controlled by the computer. Therefore, refer to your
computer documentation for details on how to change display modes.
The image size, position and shape might change when the display mode changes.
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 re-attach
the CRT monitor temporarily until you have re-configured the system; preferably to
1920x1080 at 60Hz, which is the Native Resolution Display mode.
Response time: 6ms with overdrive @60Hz
