Before sharing this, I managed to enter the BIOS only once—using an Advanced Restart in Windows to UEFI. This method worked about one in thirty attempts, which was quite inconsistent. Irrespective of the output port, whether DP or HDMI, it remained unreliable.
Recently, I purchased a riser cable and connected my old 1650. There are no pictures of either device. When I press Ctrl+Alt+Del, the system restarts into Windows, but only the 1650 appears. At that moment, I didn’t notice anything unusual, but after a minute in Windows it seemed to remove the 4090 drivers. I restarted again. While trying to access the BIOS, I noticed Fast Boot was enabled. I set NVMe to boot last, Fastboot disabled, and rebooted—successfully entering the BIOS.
After waiting about thirty minutes, I tried once more. The screen flickered black again when I accessed the BIOS. I restarted and it worked consistently now. It goes into the BIOS eight out of ten times.
Everything is confirmed (rechecked). I flashed the original GPU firmware and tested various monitors, including my TV. This is my second monitor (same model) that has achieved this; I’ll explain further if needed, but it’s already quite detailed. Windows remains fully stable, and the hardware passed a comprehensive stress test with no issues, reboots, or WHEA failures.
I found this information on Tom's HW Post, but I’m not sure what the setting refers to or if it was relevant. Any clarification would be greatly appreciated.
