AVTECH KPD679 unclear picture

[jossi007 0]

Hi,

 

I have installed a KPD679 DVR from AVTECH, but there seems to be something wrong.

When I connect a screen with a VGA cable, I get a very clear picture but when i connect the screen with a BNC cable, the picture is jumping a bit and is giving me an unclear picture.

I have tried several screens, but I always get the same result.

I have also looked through all the settings. but can't seem to find anything that can help.

Is the DVR faulty or is this normal?

 

Thanks for your help,

Laurent
