Black screen detected during testing.
Hi
My Gigabyte RX 6600 XT GPU displays a black screen before BIOS loads, but it functions properly with other GPUs like RTX 4080, RX 460 and GTX 970. When connected to a different motherboard, everything works without issues; the black screen appears only when pairing the B460-I with the RX 6600 XT. I've changed power supplies, cables, BIOS settings, and updated the firmware, but nothing resolved the problem. I also have a PCIe x16 to x1 adapter that allows the GPU to run correctly. It's unclear what else to try, as neither the motherboard nor the GPU seems faulty—only their combination causes the issue. Any suggestions on how to resolve this?
Best Regards
