Video Splitters | DuRant Media Consulting

Ideally in a live production setup video splitters should not be used because they can lower the quality of your video signal as well as add noise to your picture. However, that being said we understand that sometimes it's impossible to not use one. In this help article we discuss common issues that arise when using video splitters; this includes VGA, DVI, DisplayPort, HDMI, and SDI.

This list is not exhaustive but it does highlight common issues have been found.

Issue	Possible Solution(s)
Only one port is being used on the splitter	If only one output of the splitter is being used make sure the equipment is using output 1. Most of the time Output 1 is seen as default resolution for the secondary display, so if there isn't anything connected to output 1 nothing will be seen by your video source. Make sure everything in the chain is getting steady power. Additionally if you are only using one port on the splitter, it is best to eliminate the splitter entirely and directly connect your device endpoint to your source.
No video at any device endpoint	A simple test procedure that can be performed is by connecting each device endpoint to your source and see if it gets signal. If all of the devices get signal by this method, the next thing that should be checked is the video splitter and the video cord feeding the splitter.
No signal at only one device endpoint	The following test procedures will help determine of the video splitter has a bad output. Take a known working device endpoint and connect it to each of the splitter outputs. If it works on the "bad port", it points to something downstream of the splitter. If your known device endpoint does not work, this points at a bad port on your splitter.
