tor is missing or disconnected. Check the cable and reconnect.  
y
The "OSD LOCKED" message is displayed.  
Is the "OSD LOCKED" mes-  
sage displayed when the MENU  
button is pressed?  
The OSD lock feature is enabled to prevent undesired modification  
of the OSD settings. Press and hold the MENU button for a couple of  
seconds to unlock the OSD. (The "OSD UNLOCKED" message will be

y
The screen retains an image.  
Does image sticking occur even  
when the monitor is turned off?  
Displaying a still image for a prolonged time may cause damage to the  
screen, resulting in the retention of the image.  
Use a screen saver to protect the screen when using the monitor for a  
prolonged period of time.  
y
y
NOTE  
Vertical Frequency: In order to display an image, the screen must be refreshed dozens of times per  
second like a fluorescent lamp. The number of times the screen is refreshed per second is called  
vertical frequency or refresh rate and is represented by Hz.  
Horizontal Frequency: The time it takes to display one horizontal line is called the horizontal cycle.  
The number of horizontal lines displayed in one second can be calculated by dividing one by the hori-  
zontal cycle. This is called horizontal frequency and is represented by kHz.

The image is displayed abnormally.  
Does the display area appear  
uncentered?  
Pressing the AUTO button will automatically optimize the screen to the  
current display mode.  
If you are not satisfied with the optimized screen, you can manually  
adjust the POSITION option in the OSD menu.  
Does the screen exhibit vertical Pressing the AUTO button will automatically optimize the screen to the

If you are not satisfied with the optimized screen, you can manually  
adjust the FREQUENCY option in the OSD menu.  
Does the screen display hori-

text appear blurred?  
If you are not satisfied with the optimized screen, you can manually  
adjust the PHASE option in the OSD menu.  
NOTE  
Check if the video card's resolution or frequency is within the range allowed by the monitor and set to  
the recommended (optimal) resolution in Control Panel > Display > Settings.  
Failing to set the video card to the recommended (optimal) resolution may result in blurred text, a  
dimmed screen, a truncated display area or misalignment of the display.  
The configuration procedure may differ depending on your computer and/or operating system. Also,  
some video cards may not support certain resolutions. If this is the case, contact the computer or  
video card manufacturer for assistance.

The recommended monitor resolution (optimized resolution) of the WMS 2011 operating system is  
usually 1364 x 768, but the actual monitor resolution is 1366 x 768. This is not a monitor malfunction;  
it occurs due to the characteristics of the operating system. (Only N195WU model)  
The display color is abnormal.  
Does the display color appear  
discolored (16 color)?  
Set the color to 24 bit (true color) or higher. In Windows, go to Control  
Panel > Display > Settings > Color Quality.  
y
y
y
Does the display color appear  
unstable or in monochrome?  
Check if the signal cable is connected properly. Re-connect the cable  
or re-insert the PC's video card.  
Are there spots on the screen?  
When using the monitor, pixilated spots (red, green, blue, white or  
black) may appear on the screen. This is normal for the LCD screen.  
It is not an error nor is it related to the monitor's performance.
