buy kit HIKVISION 720 HD TVI bullet type with 4 bullet cameras. When I turned on the DVR, the brand image appeared and then the following message: "D-SUB Signal out of range 64. Okhz / 60 hz . " I would appreciate your guidance on what happens and how it is solved. The cameras connect them using Balls with 8-wire UTP cable as follows: VIDEO : blue / white blue (positive) orange / white orange (negative) SOURCE: green / green and white (positive) brown / brown and white (negative). Thank you

Hi. I did as you indicated, change the monitor and keep giving SIGN OUT OF RANGE. Change the screen resolution to a minimum on the PC and remain the same. When I tried using HDMI cable, I get the message WITHOUT HDMI SIGNAL. I tell you that I use this cable on my PC and if it works.
