Re: I'm trying to actively split VGA output of HP desktop bu... - HP Support Community

I have an HP Pavilion 550-114a. On the back of the tower I have 2 vidio outputs, a VGA and a DVI. I would like to be able to use 2 monitors as well as a projector. The projector and the second monitor would be mirrored. I am using the VGA port for the first monitor and works. If I use a DVI cable for the second monitor, only the second monitor, it works well. Or if I put the DVI cable to the projector, that works well. But if I put an active splitter after the DVI output on the tower to both the projector and the second monitor, it will not work. I am unable to recieve a signal to either one or the other. I will receive a signal to one, but not the other. This is for my church and need help understanding what I am doing wrong. Thank you for your help.

While that should work, the splitter is not doing its job. Many people and churches are doing exactly what is posted. Either the splitter is defective or there needs to something else. What model number and make is this splitter?

Also, is anything else being used in this setup - between the computer and the projector end. Most people in your situation do not have the projector within a short distance, so how far away is the projector and how is the monitor signal getting there?

Yes, the projector is about 180' away. So I am using an HDBaseT HDMI balun kit to extend via Cat6 from the tower. I'm still using a DVI to HDMI cable to the balun kit.

The DVI splitter is a VellBox DVI splitter, 1080p 1X4 5V/3A.

OK. I looked at the splitter. It shows an input for the DVI and then 4 outputs. Now from the first post, it is not exactly clear when you state it works with only the 2nd monitor or the projector but not both. Is that while having the splitter in the string and the first monitor connected VGA? It all that is yes, then connect the second monitor to output number 1. That way the splitter should pass on the monitor info to the computer. Then if it works that way, add the projector to the monitor #2

Yes, that is correct, it would go PC, splitter, #2 monitor & projector.

How would I add the projector to monitor #2? Isn't that what the splitter is for?

I'm sorry - I meant put the projector on output #2
