Hello, I recently purchased one of those new Asus ROG Swift OLED PG27AQDP 1440p 480hz displays. I soon realized that connecting it to my current system pushes the graphics card’s digital resolution beyond its limits. To resolve this, I added a second GPU—a refurbished 1070TI—to free up resources for the other monitors. Here’s how my configuration looks: Monitor 1: 1440p @ 480hz via DP 1.4 from 3090 Monitor 2: 1080p @ 240hz via DP 1.4 from 1070Ti Monitor 3: 1080p @ 240hz via DP 1.4 from 1070Ti Monitor 4: 4K @ 60Hz via HDMI 2.0 from 1070Ti The issue is that whenever I try to boot my PC, it displays the POST splash screen, then a loading icon appears, but nothing actually appears. I’m inside Windows yet none of the screens show anything. My workaround involves disconnecting all but Monitor 1, booting into Windows, launching the desktop, and gently reconnecting each cable to the 1070TI. I do this carefully—plugging them back one by one—to avoid lockups. Once I finish, the monitors 2, 3, and 4 connect and function normally at their full refresh rates. Of course, it’s not perfect; sometimes during reconnection Windows freezes. It seems like a random decision from Windows to test if I’m pushing its limits. I’m unsure if I’m hitting a hidden restriction, but my specs are solid: x570 Asus ROG Crosshair VIII Hero motherboard, Ryzen 9 5950x, 64GB DDR4 RAM, 3600MHz, plus the 1070Ti GPU and several PCIe slots. I’ve updated drivers (version 561.09), enabled 4G decoding in BIOS, adjusted refresh rates and resolutions, swapped cables, and changed connection slots. Any advice would be greatly appreciated!
It seems the problem might be related to Windows. I suggest opening Event Viewer for further inspection. If you find any logs concerning displays in the system folder, share them so someone or I can review them. If no such logs exist, consider installing Linux to test; if it works with all displays enabled at startup, the issue likely lies in Windows settings. If it doesn’t work there either, it probably points to a BIOS configuration problem.
I reviewed the event logs and noticed the driver Driver WudfRd didn't load for the specified device path. A call to SetDisplayConfig() included the SDC_FORCE_MODE_ENUMERATION flag. After running sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth, the issue remains unresolved.
Based on what I found, the best approach is to uninstall your display drivers using a tool like DDU (Display Driver Uninstaller). Look for the program, run it, and reinstall the drivers tailored for your GPUs. It’s better to visit Nvidia’s website and search for your specific cards instead of downloading Nvidia GeForce Experience, as that will install the initial drivers properly. Let me know if this resolves the issue.
