- Check and see if each color is normal and distinguishable.
- If not, please return the unit to repair area.
Screen Uniformity and Flicker
Test Signal: 1440*900@60Hz
Test Pattern: Full White Pattern
- Check and see if it is in normal condition.
1.5.10 Dead Pixel and Line
Test Signal: 1440*900@60Hz
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.
Audio
Test Signal: Voice signal (optional, depend on model)
Test Pattern: liberty
- Make sure there is audio output.
- Make sure that audio function (volume 80%) is working without noise and
resonance.
- Make sure that the sound of right and left speakers are in balance.
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
1440*900@60/75Hz
- Normally when the primary mode 1440*900@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.
