Unknown Video Modes (Analog RGB Signal)
Like all other monitors, your LCD monitor is designed to work with standard video modes. However, not all video 
/graphic cards use only standard video modes. 
Your LCD monitor uses state-of-the-art technology, which is designed to synchronize to any video mode. We 
recommend choosing one of the supported modes listed above. If you want to use an unknown mode, do the AUTO 
ADJUST at first. If AUTO ADJUST doesn’t make adjustments corrrectly, adjust the DOT CLOCK, CLOCK PHASE , 
horizontal position and vertical position manually.
