Lenovo E27q-20 27" 1440p Monitor - Manual (Page 20)

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 2560 x
1440 at 60 Hz, which is a common display mode.
The display modes shown below have been optimized at the factory.
