Plugging my laptop into a clients video wall and I can no longer see my presentation
This is PROBABLY something very basic, but try as I might I cannot figure it out.
I'm trying to plug my laptop into a clients existing AMX video system [looks like a router]. I'm using a Toshiba Satellite laptop with Windows 10. I'm sorry, but I do not know the model of their AMX system.
When I plug the HDMI cable into my laptop from their AMX, my pc display no longer shows my presentation but shows another blank desktop where I can no longer see my presentation to launch it or control it. On the clients video wall, we can get it to come up there, but I cannot tweak it (make the presentation full screen, launch other presentations, etc.) from my pc. I would THINK that what I see on my laptop is what the video wall shows. Everywhere else that I've done this, that is the case and it works great, at this clients, it is not the case. This has happened to me each time I've used both their old and their new AMX system. ONLY at this location. I end up not being able to run the presentations (videos from Quicktime).
I've gone into my Windows display settings and when things are connected, the choices are super limited, So there's not a lot there that helps. When I'm not connected to the hdmi cable, I can swap the display monitors around, mirror the display, etc. But once I plug it into the AMX- all of that goes away and I can't control it. I've tried every video/Windows tweak I can think of but can't get it to work.
Like I said, this is probably a very dump/noob mistake, but with the AMX system, I cannot find if the issue is on their end or my own.
I tried plugging it all in first, then booting up. Same thing.
I tried having my laptop up and running and plugging it in. Same thing.
Any ideas or step by steps?
