Note 1: For bright dot defect, bright area should be larger than 1/2 area of a sub-pixel to be count as 1 dot defect. A
dot defect that is smaller than the defined dot defect will be treated as small bright dot.
The drawing of 1/2 area sub-pixel definition: The 1/2 area sub-pixel can be defined as below one or more of specific
shapes (Fig.1).
Fig.1 Fig.2
All bright dot defects should not be noticeable by observer under specified inspection environment (Please refer to
item 5).
Note 2: (Fig.2) Adjacent-dot defect (refer to picture, dot 1,2,..,8 around A are all A’s adjacent dots) should be
inspected under the same display pattern in any one of White /Black /Red /Green /Blue /Monotone Gray pattern.
Note 3: Adjacent-dot defect should be observed under any one of White /Black /Red /Green /Blue pattern. 1 pair of
bright dots equals 2 dots. Inspection patterns: Standard inspection patterns of dot defect are listed below. AUO uses
these patterns as standard criteria for judging dot defect. Please inform AUO if any other pattern is to be used to
examine dot defect.

Test Pattern Defect
Full Black For bright dot(s)
Full White For dark dot(s)
Monotone Red /Green /Blue For bright and dark dot(s)
Note 4: The judgment criteria of particle occurred bright dot is the same as bright dot judgment criteria.
Note 5: The display uniformity (general mura) symptoms will use 8% ND Filter. That is, the definition of Not
Noticeable means the symptom can be covered by 8% ND Filter.
Note 6: The inspection method of ND Filter - holding ND filter in front of the panel around 1 cm and examine the
panel from 35±5 cm in the front view for 3 seconds.

Troubleshooting
Frequently asked questions (FAQ)
The image is blurred:
Read the instructions on the link "Adjusting the Screen Resolution" on the CD, and then select the correct
resolution, refresh rate and make adjustments based on these instructions.
How do you use a VGA extension cable?
Remove the extension cable for the test. Is the image now in focus? If not, optimize the image by working
through the instructions in the "Adjusting the refresh rate" section on the link "Adjusting the Screen
Resolution". It is normal for blurring to occur due to conduction losses in extension cables. You can minimize
these losses by using an extension cable with better conduction quality or with a built-in booster.
Does the blurring only occur at resolutions lower than the native (maximum) resolution?
Read the instructions on the link "Adjusting the Screen Resolution" on the CD. Select the native resolution.
Pixel errors can be seen:
One of several pixels is permanently black, one or more pixels are permanently white, one or more pixels are
permanently red, green, blue or another color.
Clean the LCD screen.
Cycle power on-off.
These pixels are permanently on or off and that is a natural defect occurs in LCD technology.
The image has a faulty coloration:
It has a yellow, blue or pink appearance.
Select MENU > PICTURE > Color > Reset Color, and then choose “YES” in the “Caution” message box to
reset the color settings to the factory defaults.
If the image is still not correct and the OSD also has faulty coloration, this means one of the three primary
colors is missing in the signal input. Now check the signal cable connectors. If any pin is bent or broken off,
please contact your dealer to get necessary support.
No image can be seen:
Is the prompt on the display illuminated in green?
If the LED is illuminated in green and there is a message “Out of Range” on the screen, this means you are
using a display mode that this monitor does not support, please change the setting to one of the supported
mode. Please read the “Preset display modes” section from the link "Adjusting the Screen Resolution".
Faint shadow from the static image displayed is visible on the screen:
Activate the power management function to let your computer and monitor go into a low power "sleep"
mode when not actively in use.
Use a screensaver to prevent the occurrence of image retention.

Is the prompt on the display illuminated in orange?
If the LED is illuminated in orange, the power management mode is active. Press any button on the computer
keyboard or move the mouse. If that does not help, check the signal cable connectors. If any pin is bent or
broken off, please contact your dealer to get necessary support.
Is the prompt on the display not illuminated at all?
Check the power supply mains socket, the external power supply and the mains switch.
The image is distorted, flashes or flickers:
Read the instructions on the link "Adjusting the Screen Resolution" on the CD, and then select the correct
resolution, refresh rate and make adjustments based on these instructions.
You are running the monitor at its native resolution, but the image is still distorted.
Images from different input sources may appear distorted or stretched on the monitor running at its native
resolution. To have the optimal display performance of each type of input sources, you can use the "Display
Mode" function to set a proper aspect ratio for the input sources.
The image is displaced in one direction:
Read the instructions on the link "Adjusting the Screen Resolution" on the CD, and then select the correct
resolution, refresh rate and make adjustments based on these instructions.
The OSD controls are inaccessible:
To unlock the OSD controls when the OSD is preset to be locked, press and hold the “MENU” key for 15
seconds to enter the “OSD Lock” option and make changes.
Alternatively, you may use
Settings” menu (under SYSTEM), and all OSD controls will be accessible.
If your problems remain after checking this manual, please contact your place of purchase or e-mail us at:
Support@BenQ.com
or keys to select “NO” in the “OSD Lock” submenu from the “OSD
