    Hi RossE,

    The panel resolution is 1920x1080p and its input interface is a quad channel LVDS, please suggest me solution for this.

    Thanks and Regards

    Is the refresh rate 120Hz?  And is the HDMI clock 297MHz?

    Thanks,
    Ross

    yeah the refresh rate is 120 Hz but the HDMI clock is 165MHz and the display color is 1.07G colors (8bit+Hi-FRC -bit/color). 

    Thanks

    1920x1080, 24-bit color, 60Hz normally uses a 148.5MHz clock.  At 120Hz it should be 297MHz.  So I'm not sure how it could be 165MHz.

    TI has a solution to receive HDMI/DVI up to 165MHz with our DVI receiver, the TFP403, and it can output 24-bit or 48-bit (odd/even) to a dual-channel LVDS transmitter.  Since we don't have any quad-channel LVDS transmitters, and we can't receive HDMI at 297MHz, it looks like we don't have a solution for you.

    Thanks,
