Lenovo ThinkVision Pro2840m Wide Flat Panel Monitor - Manual (Page 18)

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 to 3840x2160 at 60Hz, which is
the Native Resolution Display mode.
The display modes shown below have been optimized at the factory.
