Troubleshooting
No power.
- Flip the power switch ON. The Power LED turns on.
- Make sure AC power cord is securely connected to the power jack and to a
power outlet.
Power on but no screen image.
- Make sure the video cable attached with this monitor is tightly secured to the
video output port on the back of the computer
- Adjust the brightness and contrast.
Image is unstable, unfocused.
- Use AUTO-TUNE to adjust automatically.
- If the image is still unstable after AUTO-TUNE processing, please adjust
PHASE manually to get image focused.
- Check whether the resolution or refresh rate in windows display setting is
beyond supported range (please refer to the specification of supported
mode.)
Flickering
- Not enough power is being supplied to the Monitor.
Connect the Monitor to a different outlet. If a surge protector is being used,
there may be too many devices plugged in.
- See Timing Guide in this manual with a list of refresh rates and frequency
settings showing the recommended setting for the Monitor.
Wrong or abnormal colors.
- If any colors (Red, Green, or Blue) are missing, check the video cable to make
sure it is securely connected. Loose pins in the cable connector could cause
a bad connection.
- Connect the Monitor to another computer.
- Check the graphics card for proper sync scheme (or sync polarities) to match
the Monitor's specifications.
Double (split) screen image
- Make sure your graphics card is set to Non-Interlaced mode.
Entire screen image rolls (scrolls) vertically.
- Make sure the input signals are within the LCD monitor's specified frequency
range. (Maximum : 1280
X
1024 @ 75Hz)
- Connect the video cable securely.
- Try the Monitor with another power source.

ABOUT THE LCD
The LCD contains over 3,932,160 thin-film transistors (TFTs).
A small number of missing, discolored, or lighted dots on the screen
is an intrinsic characteristic of TFT LCD technology and is not an LCD
defect.
If you display a fixed pattern for more than 10 hours, its image may
remain on the screen in overlap mode when you display something else.
