Hello everyone, my specs are the following: 5950x 32GB DDR4 3200 CL 14 Inno3D iChill x4 RTX 3090 Gigabyte x570 Aorus Master (bios F33i, pure UEFI mode no CSM) Windows 10 20H2 (19042.985) Nvidia 466.27 (clean install) Arch Linux (linux-tkg-zen2 with Nvidia 465.27-1 and boot via systemd-boot) Main Monitor (Display Port): DELL U2718Q Secondary Monitor: LG OLED C9 Cable: https://www.zeskit.com/maya21 (HDMI 2.1 actually certified, 5m) With my old GTX 1070, I would always see the BIOS/Boot screens on the TV, whenever I would turn on the computer with the monitor turned off. Since I upgraded, I cannot get a pre-OS-driver screen for the life of me. This includes both Linux and Windows, with the exact same behavior. Even if I physically disconnect the DisplayPort cable from the GPU, and leave only the HDMI on, I will only get picture on the TV from the computer when Windows or KDE reach their logon screens (after the NVIDIA driver loads). Regarding Windows I don't have anything "extra", or "weird" installed. I don't have RTSS or OBS or anything beyond Steam and GeForce Experience installed. Game mode is ON, Fast Startup is disabled. I am literally on defaults on Linux. I tried to disable fast startup completely from my motherboard, but it made absolute zero difference. I also have submitted this as an issue to NVIDIA using the feedback form and never heard back. Anyone has a suggestion? EDIT: I just submitted it again.
