How to use the DPC utility
When the DPC utility starts, it will hide in the notification area (like below picture),
and double click the tray icon (shown as the red square below), 'DPC v4.2.3w', it will show.
1. Frequency of panel selection.
2. Apply the frequency of panel which user selected.
3. If checked to save DPC setting , the setting of frequency and duty cycle will be reserved.
4. It will show the MCU version of DPC.
5. Brightness control scrollbar, you can adjust volume of brightness.
6. Show the brightness value which you adjust.
7. When click the LightOff button, the panel will become darkness.
8. Set step add / subtract brightness unit.
9. Apply the step unit.
