Note:X401 the native resolution of test signal is 1024x768@60HZ.
W401 the native resolution of test signal is 1280x800@60HZ.
We take X401 for example here.
1. Frequency and tracking boundary
Procedure - Test equipment: video generator.
- Test signal: analog1024x768�60Hzx768�60Hz�60Hz
- Test Pattern: general-1 or master
- Check and see if the image sharpness is well
performed.
- If not, re-adjust by the following steps:
(1) Select “Frequency” function to adjust the image
appears to icker vertically.
(2) Select “Phase” function and use right or left
arrow key to image appears to be unstable orimage appears to be unstable or
ickers.
- Adjust Resync or Frequency/Phase/H. Position/V.
Position to the inner screen.
Inspection item - Eliminate visual wavy noise by Resync,
Frequency or Tracking selection.
- Check if there is noise on the screen.
- Horizontal and vertical position of the video should
be adjustable to the screen frame.
Criteria - If there is noise on the screen, the product is con-
sidered as failure product.
- If there is noise on the screen, use auto or manual
“frequency” function or “tracking” function to adjust
the screen.
- The PC mode functionally sure be workable include
support format with frequency and auto detected
functional will be workable.
