What if you changed the resolution of DVR system accidentally, and cannot get any display on TV from the DVR. Your monitor says out of range?
This is caused by resolution compatibility issue.
The default output resolution of the DVR is 1024*768, which may not be compatible with some screens.
Here is how to solve it:
1. Connect the DVR to any other screen via VGA cable; (or you may also try any other screen via HDMI to see if you can enter the menu) .
2. When you are able to see the menu, click right button on mouse, go to Main Menu – Setup –Basic – Video Output; change it to 1024*768 or any higher resolution that your screen can support; apply to save it.
3. Connect it back your primary screen via HDMI. You should have it worked with the screen.
