When using Magewell capture devices, we sometimes encounter a problem. After connecting the HDMI video source with the capture device directly, the screen shows "No signal" or "Unsupported signal". This problem is especially prone to occur when the HDMI cable is long. The root cause of this is that the signal output by the HDMI video source is non-standard or the standard HDMI signal becomes non-standard after a long distance transmission loss. We also found that 4K HDMI signals have more stringent requirements on transmission cables. To solve this problem, Magewell introduced Mini Repeater HDMI 4K, which can fix the corrupted signal at the receiving end, or generate a better signal at the sending end so that the user can capture the image correctly.
How to Use:
Note that other factors that may cause the same problem need to be excluded before attempting to use the repeater.
