In trying to install Ubuntu 22.04 Server on a Dell R6515, following error is reported.

"The current input timing is not supported by the monitor display. Please change your input timing to 1920x1200@60Hz or any other monitor listed timing as per the monitor specifications."

The above error occurs on multiple monitors, while other monitor simply display a blank screen at this step. The server has only two VGA ports, and both yield the same result.

This answer provided a method to get through this problem.

On the selection to Try or Install Ubuntu, hit e to get to the Grub menu.
In the line that starts with linux, add nomodeset to the end of the line. This setting will provide a usable display.
