Lenovo ThinkVision LT1423p 13.3-inch IPS LED Backlit LCD Wireless Touch Monitor with pen - Manual (Page 17)

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 1600 x 900 at 60 Hz, which is the Native Resolution
Display mode.
The display modes shown below have been optimized at the factory.
