    Overview The Kramer VP-774AMP is a high quality presentation switcher and scaler. It accepts one of nine inputs: an SDI signal on a BNC connector, a DisplayPort (DP) signal on a DisplayPort connector, one composite video signal on an RCA connector, two computer graphics signals on 15-pin HD connectors, and four HDMI signals on HDMI connectors.
  • Page 11 System Range - Up to 130m (430ft) normal mode; up to 180m (590ft) ultra- mode (1080p @60Hz @24bpp) when using BC−HDKat6a cables For optimum range and performance using HDBaseT™, use Kramer's BC−HDKat6a cable. Note that the transmission range depends on the signal resolution, source and display used.
