Note:
1. Show "Input Not Supported" warning message.
When Vertical Frequency is over 76Hz or under 56Hz, the display is Black and showing "Input Not
Supported" warning message. (Some video timings are except for PAL, 50Hz signals.)
2. If Hf /Vf is set in the range of 31KHz~83KHz and 56Hz ~76Hz (not including some video timing), and
Pixel Clock is set in the range of 25.175MHz~173MHz(DVI and HDMI input port 165MHz for Single-
Link), but is not the above Resolution, then it will display the nearest mode.
5.1.3 ADC calibration (Auto color balance adjustment)
~~Analog only, it is not required for DVI-D input source
1. Setup input timing ICL-605( 1280x1024@75Hz ), pattern 42(5-Mosaic pattern with white color block)
with Analog signals from Chroma video pattern generator. (it depends on Scaler IC supplier's
recommendation)
2. Enter factory mode (press "Empowering" & "Power" buttons at the same time to turn on monitor).
3. Move cursor into "Burn-in Mode" tag and select "On" to enable burn-in mode.
4. Close OSD menu then press "Auto" button for auto color adjustment. (This procedure will get optimal
gain/offset(clamp) values)
5. Checking if the picture is ok, or reject this monitor and check its circuit board or wire/cable connection.
5.1.4 Color temperature adjustment
1. Setup input timing to any preset modes, pattern 41(full white color pattern) with Analog signals from
Chroma video pattern generator.
Enter factory mode (press "Empowering" & "Power" buttons at the same time to turn on monitor).
2.
Move cursor into "Burn-in Mode" tag and select "On" to enable burn-in mode.
3.
4. Make sure ADC calibration (auto color balance adjustment) had already been done.
5. Measure color temperature by Minolta CA-110 (or equivalent equipment).
6. Adjust the color temperature ~~ Two methods can be used to adjust RED, GREEN, BLUE value of
each color temperature, C0/Cool, C1/User & C2/Warm to meet following spec requirement, the 1
using external PC and IIC alignment protocol to do automatic adjustment, and the 2
and must be in factory mode.
