I no longer have this problem as the computer now has a DVI monitor directly connected to the DVI output. When this was an issue, the DVI output connected to a VGA monitor via a DVI-VGA adaptor, because I was using a KVM switch with a second computer with a VGA output. Using the VGA monitor with a PC with a VGA output didn't cause a problem.
I don't know enough about the details of monitor detection to know if it should work with such an adaptor. As pretty well all monitor detection is automatic nowadays, an adaptor which broke the detection process with Windows, for example, should be unsaleable. I only run Ubuntu, so cannot see if the DVI-VGA adaptor fails or works with another operating system, where Linux or Windows. Unless the use of these adaptors is something that you need to support I would close the bug report. I thought I had already indicated this in a previous email. Thanks for caring.
