Lenovo L24q-35 23.8" 1440p Monitor - Manual (Page 19)

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