Q38.What should I do if there is no picture on the TV/monitor?

A. If there is no picture on TV

Please use your TV remote control to switch signal source. If the signal source is right but you cannot get display, this is typically caused by resolution compatibility issue.

The default output resolution of the NVR is 1280 x 1024, which may not be compatible with some screens.

Here is how to solve it:

Step1. Connect the NVR to any other screen via VGA or HDMI to see if you can enter the menu.

Step2.Go to Main Menu→System→Display ; Change it to 1080p@60; apply to save it.

Tips: Never try 1080p@50 especially in US

Step3. Connect it back your primary screen. You should have it displayed on the screen now.

B: If the monitor always shows the following two pictures.


The monitor's resolution must be higher than the display resolution of DVR. If not, monitor is not able to show any image of cameras. The NVR default resolution is1280 × 1024. If monitor can't show any image of cameras, it can prove the display resolution of NVR is higher than your monitor's, please use a higher than 1280 × 1024 resolution monitor to connect NVR.
