Daryl733 0 Posted April 30, 2016 Did you check with the vendor ? Can't find any information online and I'm not going to open those .doc files that the search results returned. This is one of those unbranded equipment. You'll most likely need to check with the vendor. Either 1. The port is there for show and not a working port. Seen a few of those before. Including on PC as well. 2. There's a hardware/software switch to alternative between HDMI/VGA (Only 1 can be working at any one time). - Try disconnecting your HDMI and only connect a VGA cable. Switch off the system and power it back on and see if there's output on VGA. 3. Some configuration in the DVR to enable or select the port. Here's a russian site on it. https://www.drive2.ru/l/8412045/ Can use google translate to english. Share this post Link to post Share on other sites
