  Ghosting or visual delays in the output images from your Monoprice Extender can be due to a couple of reasons. First, incorrect display settings could be the cause, so check those settings. Second, a poor-quality cable might be the culprit. Try using a different, high-quality cable to see if that resolves the issue.

  If your Monoprice Extender fails to recognize a device connected to its Ethernet port, it's possible that the connected device shares the same IP address as the extender. To resolve this, change either the IP address of the extender or the IP address of the connected device.
