The new system unit. The new monitor of BenQ PD2500Q. In a set cables HDMI and DP - miniDP. From the system unit there is no image on one of cables. Thus from on HDMI the image is. From this like properly that with the monitor everything is all right. But that can be not so with which besides connected to the monitor in output point, and transportation transited without adventures. Well all right one HDMI would not work, so I also through the third cable, "normal" DP tried, the same result - the monitor writes that the signal is not found out. And from very much even it is found out.
