It's not a resolution issue, it's a screensaver.  You might try adding
"acpi=none" on the boot command line during the installation to disable

Screensaver? In my experience, "input signal out of range" usually indicates
a mismatch between the monitor's needed "refresh rate" and that being made
available by the OS and/or graphics card.
