I was THRILLED to find this software. I had seen old messages about a product called MaxiVista, and then was disappointed to find that it's no longer around. So again, absolutely thrilled when I came across this software.
When it works, it works great! I have both the server and client set up and they work in general. I can connect and I extend my primary computer's display to the other computer, and it works great for a short while, but after being connected for anywhere from a few minutes to 20 or 30 minutes (20 to 30 is about the longest it has ever stayed working), the server software just quits. No errors or anything, it just quits.
Both computers are Windows 10, 64-bit
Primary computer has an Intel GPU, and is using a wireless network connection.
Secondary computer has an nVidia GPU and a hard-wired network connection.
But both PCs are still on the same network.
