Lenovo LI2821 Wide LCD Monitor - Manual (Page 22)

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 to change display modes.
The image size, position and shape might be changed when 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(VGA),3840 x 2160 at 30Hz(HDMI), 3840 x 2160 at 60Hz(DP),which is a common display
mode.
The display modes shown below have been optimized at the factory.
