The only connection you should use on the motherboard is a USB 3.0 port, not any video outputs. Using a video out will cause problems. For additional USB ports, consider a PCI-e card or a hub for devices that don’t require high bandwidth or low latency. If you’re really limited with video outputs and your GPU isn’t powerful enough, adding a second GPU is the best solution.
Thanks for the advice Raz. The Steam VR sends signals via the compact GPU (2070 Super). There are several display port connections on the card plus one HDMI output that links to a monitor, which the OS assumes is the sole display. Setting up multiple monitors with an NVIDIA control panel lets you create a virtual desktop environment similar to Virtual Desktop, enabling each extra screen to function as a virtual workspace in VR. This setup works smoothly without issues, though it won’t recognize additional displays unless they’re connected to physical screens. Without them, the NVIDIA Control Panel can’t detect them and you can’t add more desktops. You might use headless adapters that pretend to connect to generic monitors, but this is limited by the GPU’s port constraints. While you can partially virtualize this scenario, it usually needs external tools like screen casting or RDP. Essentially, the OS must understand how to route the display data it receives—a challenge not encountered before. Back then, supporting more than three or four desktops in virtual space wasn’t common. I hope improvements have been made since... It seems NVIDIA’s GPU and built-in graphics can manage such setups now. I could allocate 64MB of video RAM just for this task in my BIOS for regular non-RV use.
It looks like you're clarifying a few points about your setup. The motherboard video output can often work alongside a dedicated GPU, though compatibility depends on the board. Also, whether your CPU includes built-in graphics varies by model.
Intel 10700 details are solid. The motherboard model isn’t clear, but the ROG Z490 G remains up-to-date. It’s possible over the past few years someone developed a custom card to address this particular need—something like specialized display adapters. The main challenge is that it’s a very specific problem in a limited segment, similar to niche peripherals.
