Dear Sir,

     my customer Hikvison is using the ADV7619 on their large pannel and HD video conference system; it has already support the 4K*2K HDMI input sucessfully;  now their end customer need them to support the 2800x2100 30Hz HDMI/DVI input from PC, the detail time as attacehd picture:

  as the pixel clock is 187Mhz, it exceeds 170Mhz, customer uses the 48bit (2*24bit) output format, similar with the 4K*2K 30Hz setting; but the ADV7619 can not output right video signal (clock/HSYNC/VSYNC); by the ADV7619 STDI block, the resolution detection is right;

    below is the registers setting, please help to give your comments for this issue:
