5.4.1. Overview
▪ V-COM adj. Objective & How-it-works
- Objective: To reduce each Panel’s V-COM voltage deviation
- How-it-works: When V-COM gain in the adjust-OSD of each
SET is at default value, each SET can have flicker by each
Panel’s V-COM voltage deviation. In order to prevent flicker
of each SET, find the desired each Panel’s V-COM voltage
value.
- Adj. condition: normal temperature
1) Surrounding Temperature: 25 ºC ± 5 ºC
2) Warm-up time: About 5 Min
3) Surrounding Humidity: 20% ~ 80%
5.4.2. Equipment

(2) Zero calibrate probe then place it on the center of the
Display
(3) Connect Cable (RS-232C to USB)
(4) Select Model in “V-com adj. Program” and begin “V-com
