ViewSonic Corporation

Confidential - Do Not Cop VA916

Test Signal: 1280*1024@60Hz

www.ma163.com 电子技术资料网

Test Pattern: Dark and White Screen Pattern

- Check and see if there are dead pixels on LCD panel with shadow gauge and
filter film.

- The total numbers and distance of dead pixels should be compliant with the
spec.

Mura

Test Pattern: White, RGB, Black, & Grey
Test Tool: 10% ND Filter

- Check if the Mura can pass 10% ND Filter.

Check for Secondary Display Modes

Test Signal:

Analog: 640*480@60/75Hz;
720*400@70Hz; 800*600@56/60/72/75Hz;
1024*768@60/70/72/75Hz; 1280*1024@60/75Hz

- Normally when the primary mode 1280*1024@60Hz is well adjusted and
compliant with the specification, the secondary display modes will also be
compliant with the spec. But we still have to check with the general test pattern to
make sure every secondary is compliant with the specification.

All Modes Reset

After final QC step, we have to erase all saved changes again and restore the
factory defaults. You should do “All Mode Reset” again.

Power Off Monitor

Turn off the monitor by pressing “Power” button.
