    "Out of range" after new gpu and monitor

    Hello, I upgraded my monitor to a 2k benq and my gpu to a gtx 1070.
    When i try to boot my working fedora from and external ssd I get to choose "fedora with linux" and i see the bar loading but one i get to the desktop my monitor goes black with the out of range error.

    I tried reducing the resolution and installing the latest drivers but it doesnt work

    The resolution itself should not be a problem as 2K is only 2560 x 1440 and the gtx 1070 can support a maximum resolution of 7680x4320@60Hz, so 9 times the number of pixels.

    It could be kernel modesetting which the NVidia binary doesn't support. You should put nomodeset as a kernel parameter in grub. There are people with modeset problems with standard HD monitors.

    https://www.systutorials.com/qa/1825...ora-and-ubuntu gives a good explanation. After adding nomodeset, regenerate grub with

    sudo grub2-mkconfig -o /boot/grub2/grub.cfg

    Re: "Out of range" after new gpu and monitor

    I should have given more details in my first post as I was unaware that you were a beginner.

    To add kernel parameters to grub for booting you need to edit the /etc/default/grub file and add nomodeset to the GRUB_CMDLINE_LINUX variable.

    Then as smr54 said you would then regenerate the config by running either sudo grub2-mkconfig -o /boot/grub2/grub.cfg for a BIOS/CSM system or grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg for an UEFI system.

    To do a simple one time test to see if adding nomodeset will fix your problems you can edit the grub command line at boot time by pressing 'e' to edit the command line before the timer runs out.
