 x 100 %

♦ One maximum value of three estimated values.

♦ For this test ,an LMD(Light Measurement Device)is needed with adequate response time to track any visible rate flicker component and with a voltage level output proportional

To luminance intensity.

♦ Test Pattern: For dot inversion Driving(Gray levels of foreground dots on the test panel

Are G22,G32,and G45)

♦ Test Point :Center point of the display area

10

Note 8) Definition of Crosstalk (Refer to the VESA STD)

The calculation for shadowing is made from the 2 luminance measurements Gbkg and Lsh, as follows:

C

T

-Lmin

=  x100 %

Lmin

Where Lmax is the larger value of Gbkg or Lsh , and Lmin is the smaller of the two.

♦ To determine background and foreground levels (colors),first set the background to any gray scale or color level suitable for shadowing determination.(Note that it may take several iterations of adjusting background level and box levels to determine the proper value for the background .Next display the box levels to determine the proper value for the background level. Look for shadowing in any direction from box E. Independently vary the gray level (or color) of the background and box E until the worst case shadowing is observed. This defines the background (Gbkg) and foreground (Gfg) levels to be maintained for the remainder of the test.

♦ One point only (the target) will be measured. To determine that point proceed as follows

Using the background and foreground gray levels of step1 (Gbkg and Gfg). Turn on each box at a time. Look for the case with the worst shadowing. The box causing the worst case is the shadowing source, or Bsrc. Use Bsrc and the box opposite from it that lies directly in the shadow path. That is the target box, or Btgt. Note that box Eight be either Bsrc or Btgt, depending on the shadowing conditions, but typically Bsrc and Btgt will be a pair of opposite boxes, A&C or B&D. Btgt will only be displayed for aligning the LMD. It will be turned off for the actual measurement.

♦ The target box point (Btgt) will be measured with the source box (Bsrc) turned on then off.

(Btgt is for alignment purpose only) Display the background only at level Gbkg. Display

Btgt determined in step 2 above. Using the correct distance, angle, and measurement aperture, align the LMD to the center of the Btgt. Turn off Btgt. With Gbkg set to its proper level, measure the luminance (or color). Next,turn on the source box Bsrc. Again measure at the center point of Btgt (without Btgt present.). In this case the LMD will be measuring the shadowing level, Lsh.

If the input timing is not a supported timing listed above but within the supported frequency range (Horizontal: 80KHz,Vertical: 75Hz), this monitor will select a closest mode instead. But the display quality may not be optimized.

If the input timing over the supported frequency range, a message “Input Signal Out of

Range” will be shown.

Intellectual-Auto AM939 can start the Auto-Adjustment automatically when input a new display mode at first time less then 4 sec to finish. After the adjustment,

AM939 will remember this mode and switch to optimized condition automatically for this mode whenever encounter this mode again.

The 640 × 400, 720 × 400 mode can do graph/ text select on OSD Advanced function.

Total 13 recent used modes are recorded into EEPROM. If other support modes input to monitor EEPROM will cancel by first in first out motion.

After finishing adjustment from OSD, the data need 3 sec to save NVRAM memory.

VESA DPMS Functionality When signaled by the host CPU, AM939 show a black screen about 5 seconds. If no further signal, then it shows “No Signal” and enter power saving mode.

2.7.4 Power Management

2.7.4.1 Meet VESA DPMS proposal

The monitor must comply with the Microsoft On Now specification, with a minimum of three power management states, as defined by the VESA DPMS document. The front panel of the monitor must appropriately display the DPMS state, For example:

DPMS ON :

DPMS OFF :

The power LED is Blue

The power LED is Amber
