I had the same problem. EDID failed, so my computer could only start up in low graphics mode after telling me that there were not suitable modes. When I took out the vga switch (konig 4-port manual switch), the monitor was detected correctly. Apparently, the EDID wire is not connected in the switch. As a workaround, I now boot without the switch and connect the switch after booting. I never shut down. I only hibernate my computer. Updates that require a restart can be annoying this way, though. I hope this helps someone.
