Lenovo Q27q-20 27" 1440p HDR Monitor - Manual (Page 18)

Chapter 2. 2-7
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 75 Hz, which is
a common display mode�
The display modes shown below have been optimized at the factory�
