Check if the count limit windows are being monitored.
Hello, your plans sound exciting! Regarding your setup, there isn't a strict limit on the number of OLED touchscreens you can connect to a Windows PC, but factors like power supply, cable management, and system performance will play a role. Let me know if you need more details! Greetings, Plermpel
My view on Windows suggests there’s little restriction based on how advanced you want it, it mainly relies on your equipment and programs. I’ve managed eight monitors on one system before without problems. The first three were on a 1080p display, then a USB hub let me add more screens.
Typically, there’s a cap on how many monitors you can connect to a GPU. Most consumer GPUs allow up to four displays or a combined resolution limit for the attached screens. It seems the GT 730 supports only three monitors. A quick search also indicates Windows 10 is restricted to ten monitors, though this is mainly due to the applet used rather than an actual hardware restriction.
The system has constraints, likely under 256 or 128 displays (real or simulated), plus limits on window count and objects visible across all screens at once—probably around 32k to 64k items. HOWEVER, your method seems suboptimal... linking monitors via cables would create long wires and hardware challenges. A better idea would be to use a tablet (like an iPad) connected via Ethernet to the server, powered through Power over Ethernet on the same cable. Alternatively, the tablet could run wirelessly, drawing power only, and connect to a management site where each household device gets its own web interface. Or implement Remote Desktop connections so each tablet displays a different screen or virtual monitor from the central server.
You must be connected to the server to manage the house. The recommended tools are similar to Home Assistant or comparable platforms. Simply place tablets or other devices in various locations and link them to the web server of the software you use. This approach is more efficient and cost-effective.
All systems in the house will run on a Siemens S7-1200, I’m coding the software myself. As an electrical engineer and my wife is a software developer, we’ll figure it out. I don’t want the screens glowing constantly, especially in the bedroom, and buying many tablets would be expensive and unreliable. The new ASUS version supports 4 HDMI displays and is affordable. So far I’m planning to use 17 FullHD screens. 14x 5.5-inch Waveshare AMOLED screens, 3x ASUS VT229H 21.5-inch touchscreens.
The model supports up to 4 graphics cards at once. Checking the PCIe slot count will confirm if you can add a fifth card.
Windows doesn't have a fixed physical boundary; it depends on your hardware capabilities. It seems the system behaves similarly to what I experienced when setting up display systems—maximum addressable screens is 10. To go beyond that, you'll need software capable of managing it.
