The LCD monitor has shadows, lines, or ghostly, blurry, fuzzy, hazy, tinted, or faded images or colors.
NOTE: Because each of these steps can be a possible resolution for display issues, check the display function after completing each step.
- Ensure the monitor cables are correctly connected .
- Remove any monitor extension cables.
- If the monitor accepts more than one input source, press the INPUT button on the monitor to cycle through input modes.
- If using the AC adapter, disconnect the AC adapter from any power strip or surge protector and connect it directly into a wall outlet.
NOTE: If this eliminates the display issues then the problem lies with the power strip or surge protector. Contact the manufacturer of the power strip or surge protector device for further assistance.
- Remove any magnetic devices, electrical devices, speakers, lamps or fans from the vicinity of the computer.
- Remove any devices connected to the same wall outlet or electrical circuit as the monitor.
- Turn off any florescent lighting in the vicinity of the computer.
NOTE: Electrical devices and florescent lighting produce an invisible field of electromagnetism that cause an effect called Electromagnetic Interference (EMI). The display elements in both Cathode Ray Tube (CRT) and Liquid Crystal Display (LCD) monitors use precisely calibrated components that can be adversely affected by EMI. Moving such devices away from the monitor will minimize the affects of EMI.
- If the issue is that the fonts and text are distorted or blocky, it may be necessary to adjust the pitch and phase settings of the monitor.
- Reset the LCD to the factory default settings.
- Perform a self test .
- Wiggle the cable where it connects to the LCD panel.
- The LCD has two possible connection methods, using either the HD-15 cable or the DVI-D cable.
- Ensure the input selected corresponds to the input port being used.
- If wiggling the cable causes the problem to go away and then come back, the cable may be damaged or have an electrical short, or the connector on the LCD is faulty.
- If a video pass-through card is being used, bypass the video pass-through connection and connect the monitor directly to the video card.
NOTE: If this eliminates the display issues then the problem lies with the video pass-through device. Contact the manufacturer of the video pass-through device for further assistance.
- Move the computer and monitor to a different room.
NOTE: If this eliminates the display issues then an EMI or AC voltage problem exists in the original room. A line conditioner may help, but is not guaranteed to resolve voltage problems.
- Connect the monitor to a different computer.
NOTE: If this eliminates the display issues then a software or video card problem exists on the original computer.
- Replace the monitor cable being used with either a different cable of the same type, or a cable of another type (HD-15/DVI-D).
If the display problems persist after replacing the cable, the connector on the LCD is faulty and service will be required to resolve the issue.  Go to Product Repair.
