Currently you have three monitors—two at 60Hz 4K and one at 240Hz 4K. You recently added a fourth monitor (60Hz 4K) for $110 at Best Buy. Your CPU is the Intel Core i7-12700K and the motherboard is an ASUS TUF Gaming H670 PRO. When connecting all four monitors to your GPU, only three function properly. You considered keeping the main three on the GPU and using the new monitor through the motherboard display port, but you’re not getting a signal. You tried various cables and an HDMI connection. It seems the BIOS might have a setting you need to enable for proper video output. I’m not sure if that’s necessary, but your CPU and motherboard should support it. Turning off and turning back on the PC resolved the issue, allowing all monitors to work.

System settings are all set? The iGPU appears in Device Manager, but you might need to turn on the iGPU multimonitor option (look in your motherboard manual for details).
