My setup was going fine and then I bumped some button on the DVR and I see a "Display settings changed" or some similar message. I go into Setting, Display and change to 1920x1080. The DVR reboots and not I have nothing but a black screen and a"Input not supported" message. I have a VGA cable connected and have tried the monitor (which is what was wokring before), a laptop, and a TV and I cannot get a picture to resume setup. I can't find any way to factory reset or a backdoor into the menus. Please help!
BTW, I can still see my cameras on my phone
Input not supported
Re: Input not supported
I figured out my problem. Once you switch to 1920x1080 resolution you have to swap your VGA for HDMI. Helps to read the manual.
