I think this can be done, but I don't know exactly where to start.  We do the presentations with EasyWorship software on this Dell laptop.   Currently we are using VGA cable to an overhead projector and want to change the display to three TV/monitors.  This laptop only has one HDMI out for cloned or extended desktop display.  Running the "getting more aggravating everyday" Windows 10.  

 

I know we will need to buy two or three monitors (have one that might be okay), but there is some sort of "network" that would need to be set up and the TVs would have to have receivers.  It seems a trip to the electronics hardware store is going to be needed and possibly somebody that knows what to do to make it work.

 

Advice is welcomed if you have any experience with doing this king of thing.

You should look into the device called Chromecast by Google.

What type of router is on the network? You need one that can handle the cast.

Another type of device similar to Chromecast/GoogleCast is Airtame https://www.youtube.com/watch?v=8NB9S4CDPDA

To answer your question about the router - there isn't one.  This is set up as a stand alone with external monitors.  There is a device that the computer video output feeds into and it is split between two external monitors.  Everything is done with cabling.  We are going to want to go to 3 monitors on a wireless network or a wireless version of what we are doing now.  I'll start looking at Chromecast and Airtame.  

Thank you for your suggestions.

I watched this video and it certainly looks like it would do what we need it to do, but there's no information on pricing.  I did find something on Amazon indicating a price of about $270. That would mean that I would be broadcasting to 3 TVs so I would need 3x$270 -> $810 for three of these devices? One for each TV.

Googling around on this problem there seems to be the possibility of a different solution. There seem to exist a range of products called HDMI splitters, a company called Vanco make several and there are one or two other makes. These appear to be cable to splitter, cable to each TV. However I have no idea how well these work nor if there are any restrictions on length of cable. I merely throw it in as a possible alternative, and it is certainly reasonably cheap.

 

Purely as an example of what I am talking about -

Before deciding to go down this route I think I would do some research on effectiveness.

Thanks for the suggestion, Chris, but I believe there is a cable length issue with HDMI cabling.   I was hoping to do this wireless so the onerous job of pulling  cables could be sidestepped.  The Airtame approach seems it would do that, but there seems to be a latency issue that would likely be untenable.  So, now I am looking at HDMI to Ethernet extenders which gets me back into the hard wire irritation.  Still, that may be my best option.

Just a bit of history on the system:

 

Back in 2010 when I began working with this, the laptop was an HP DV4000 laptop.  Now replaced by a Dell laptop with only HDMI video/audio out.  This runs through a converter/splitter which separates the HDMI into SVGA and audio out.  This plugs into the video/audio splitter for the remote TV and the projection system.  I'm not sure what that hardware is or how it works as the remote TV is HD and the projector is SVGA, but it works.    Somehow.   At least it sort of does.  Was never an issue on the old laptop, but getting the projector set as extended monitor is quite onerous.  The computer thinks it is sending output to the remote HD TV, which it is, but that signal doesn't work well on the projector.  

So, it looks like a major overhaul/replacement  will be needed to get the two screens up front for the congregation and the single HD screen at the rear of the sanctuary for the pastor and choir.  This thread is about getting the audio/video to all three TV/Monitors with minimal latency.

When you're talking minimal latency you probably want to go with a wired solution.  This page sounds exactly like your situation.

Be aware that Chrome Cast you need a device for each tv. The device plugs into hdmi and usb. So the tv's need to support that. HDMI carries both video and audio and the usb dongle is for the Chromecast device to draw power from the usb port on the tv.
