Originally,my eyeonet 4 port card worked fine on all network pc monitor client software. My main pc took a dump and I had to replace it with the DVR pc. Set up another pc for the DVR card. Have a network problem on all monitors on pcs with client software. Every network pc monitor shows a series of black and green vertical bars. PC with DVR card works perfectly. Tried a multitude of vid cards on the dvr pc to no avail. Tried every possible monitor resolution on all systems. I'm now lost. Anyone have an answer or possibly another cheap card that has all these functions and works? Thinking I have a network settings issue.
