Lenovo recommends  
the use of the 
ThinkVision Duo 
software to optimize the 
dual screen operation  
as it simplifies the 
configuration and 
display of both video 
outputs from your PC. 
The detailed information
please refer to “Using 
the ThinkVision Duo 
software control” on 
page 2-4 
 
 
Note: In dual-screen mode, it is normal that the screen performance (such as brightness, contrast) are a little different,   
due to the different image transmission methods used by VGA and DP.

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 1920x1080 at 60Hz, which is the Native Resolution Display   
mode. 
The display modes shown below have been optimized at the factory.

Understanding power management 
Power management is invoked when the computer recognizes that you do not   
use your mouse or keyboard for a user-definable period. There are several states   
as described in the table below.   
For optimal performance, switch off your monitor at the end of each working day,   
or whenever you expect to leave it unused for long periods during the day.

Image rotation 
Before rotating the monitor, you should set-up your computer to rotate the image. 
Rotating the image may require special rotati on software or you may find that your 
computer is preloaded with video graphic drivers that allows image rotation. Check 
the Graphic Properties setting on your comput er to see if this feature is available. 
Try these steps to check if image rotation is available on your computer. 
1.  Right-click on the desktop and click  Properties. 
2.  Select the  Settings tab and click  Advanced. 
3.  If you have ATI, select the  Rotation tab and set the preferred rotation. If you have 
nVidia, click the  nVidia tab, in the left-hand column select  NVRotate, and then 
select the preferred rotation. If you have Intel, select the  Intel graphics tab, click 
Graphic Properties , select the Rotation tab, and then set the preferred rotation. 
Check with the manufacturer of your comput er to see if graphic drivers with image 
rotation can be downloaded from their support website. 
  
Caring for your monitor 
Be sure to turn off the power before you perform any maintenance on the monitor.   
Do not:   
●    Apply water or liquid directly to your monitor. 
●    Use solvents or abrasives. 
●    Use flammable cleaning materials to clean  your monitor or any other electrical   
equipment.  
●    Touch the screen area of your monitor with sharp or abrasive items. This type of   
contact may cause permanent damage to your screen.  
●    Use any cleaner which contains an anti-static solution or similar additives. This   
may harm the coating of the screen area.   
Do: 
●    Lightly dampen a soft cloth with water an d use this to gently wipe the covers   
and the screen.   
●    Remove grease or finger marks with a damp cloth and a little mild detergent. 
  
Detaching the monitor stand 
After placing the monitor face down on a clea n surface or soft cloth, remove the four 
screws from the stand to remove it from the monitor.
