Lenovo L2021 manual Selecting a supported display mode

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. This is normal and the image can be readjusted 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 re- attach the CRT monitor temporarily until you have re-configured the system; preferably to1600 x900 at 60 Hz, which is the Native Resolution Display mode.

The display modes shown below have been optimized at the factory.
