HIKVISION DS-7608NI-K2/8P NVR . Her's the problem..I have VGA connection to HDTV(1080p) and camera video is there and mouse works fine. The HDMI to this TV will not display picture at all even at the lowest resolution even after I manually change and apply the setting from VGA to HDMI, the NVR changes itself back to VGA and all works fine! However I am trying to connect this NVR to a new 4K HD monitor and eliminate the TV...So, I hook up the HDMI to the monitor and no matter what setting I try, The TV is the MAIN and I can't get the mouse cursor to show on the aux monitor screen in 4K setting, it wiil work lowering the resolution to 1980 but then the MENU to control the NVR's settings/playback disappears! Frustrating. I get no mouse cursor on monitor when just the monitor is hooked up to NVR by HDMI , all resolutions tried. In a nutshell the TV wants to be the main output by VGA and I cannot control the NVR on the monitor even hooked up standalone HDMI.
