"Out of range" error when using HDMI on an Nvidia RTX 2080

[edited by TauKakao]

Issue Description

[I have a] M28U Gigabyte monitor. The graphics card is an Nvidia GeForce RTX 2080. I managed to get a display without the 'out of range' message by replacing the HDMI 2 cable and using a DisplayPort adapter. [...]

On what version of Vanilla OS this happens?

Vanilla OS 2 Orchid

Additional Information

[...] The 3D card is an Nvidia RTX 2080 on a G1Assassin-2 Gigabyte motherboard with DDR3 memory, and an Intel i7 processor. There's no TPM, yet it can run Windows 11, albeit with slower login times.

This bug impacts VanillaOS, the current version of Kubuntu, and Debian 12 KDE. It does not affect Debian 12 GNOME-based distro, but since the Nvidia driver wasn't installed on it,

it's presumed that the "out of range" bug doesn't impact open-source Nvidia drivers, which are used by openSUSE and Fedora, as they operate without the "out of range" message.

Thanks for reporting, but please write shorter bug reports. I had to edit it because it had a lot of duplicate information.
