  • Page 4: Assembly Notes

    ASSEMBLY NOTES This controller is designed for monitor and custom display projects using 1920x1200 or 1920x1080 or 1600x1200 or 1680x1050 or 1440x900 or 1366x768 or 1280 x 1024 or 1024 x 768 or 800x600 or 640x480 resolution TFT panels with a VGA, SVGA, WXGA, XGA, SXGA, UXGA or WUXGA signal input.
  • Page 5 22. HDMI audio output : Support HDMI audio with stereo output. The HDMI audio output can be connected to Audio add-on board P/N 416940020-3 by using the audio cable P/N 426451800-3 (310mm) connected between SGX-1920 (connector : CN10) and Audio add-on board P/N 416940020-3 (connector : CN2).
  • Page 6 inverter used. Normally, power supply with 3.5Amp current output should enough for most of 4x CCFT panels. Although the controller provides power regulation for the LCD power this does not relate to the power supplied to the backlight inverter. If an unregulated power supply is provided to an inverter any fluctuations in power may affect operation, performance and lifetime of the inverter and or backlight tubes.
