Note:
1. Show “Input Not Supported” warning message. When Vertical Frequency is over 76Hz or
under 55Hz, but Pixel Clock is between 25.175MHz and 135MHz, the monitor can show
image, and the same time has “Input Not Supported” warning message. If Pixel Clock is over
the range of 25.175MHz ~ 135MHz, the display is Black and show warning message.
2. If Hf /Vf is set in the range of 31KHz~80KHz and 55Hz ~76Hz, and Pixel Clock is set in the
range of 25.175MHz~135MHz, but is not the above Resolution, then it will display the nearest
mode.
