Hikvision 7608NI with 8 cameras. With 8 cameras there are actually 9 windows of the same size showing on the monitor. When any of the cameras go into full screen mode (initiated by line crossing or manually) the grid lines from the windows are still present on the screen. The camera image is there but is overlayed with the grid lines. This started within the last few days and I don't have a clue as to what setting I should look for to correct it. Any help appreciated.
