    I have a Windows 10 pro deskop which has a main monitor connected via DVI on the built in graphics card. This card also has a VGA output to a VGA splitter, which has a VGA out for a second monitor and also 4 cat5 to VGA outputs. Off these outputs I am running 2 different projectors. My main projector works without a problem, but the 2nd one can't find the source. I've connected this projector directly onto the VGA output from the graphics card and this works fine., I've tried a 3rd projector and this also works ok. I've tried the same setup with a windows 7 laptop and the setup works ok. All cables have been replaced. Any ideas would be much appreciated.

    Hi Viper

    have you tried swapping the projectors around as well as the different cables?. :):):)

    How long are the cables? I've setup a configuration like this with 50' VGA cables, but not VGA over Ethernet. Ethernet has a 328' (100m) limit. If you are driving two cables, there might be more strain on the card which would lower limit.

    If you notice in the bottom left of the image. It speaks of signal loss over greater distances. Splitting power down two cables will weaken the initial power levels. And using converter blocks such as VGA to Ethernet, introduces multiple connection points that could also be problematic.

    My only thought at the moment would be to see if shorter cables might work. That is assuming you are connected over a good sized distance at the moment. If you can't get the card to drive two projectors short distance. You will never get greater distances to work.

    One thing you might can try is a Booster of some sort. Whether it be VGA or Ethernet, it might work for you. This is what the image is talking about in the bottom right.

    Or possibly Ethernet over Power. [not to be confused with power over ethernet]

    Presumably , you have gone through the Win 10 settings (display - multiple displays -, and, advanced from that point?)
