1. What kind of video card is this?
2.How is the video connected to the monitor? (DVI/HDMI/DisplayPort/VGA)
3. What kind of monitor is it?
4. What version of Fedora and is Fedora trying to do X or Wayland?

Sometimes if Fedora can only go to generic 640x480 the video card is no
longer 'supported' by the various X11 drivers.. or the data that the
monitor is returning to say what it can support is coming back as 640x480.
Finally this may do better on a fedora mailing list (but they will ask the
same questions). For a CentOS viewpoint I would ask if it happens if you
run CentOS-8 (try via a live cd) on the box. If it does happen, then it is
a problem between Fedora-18 and Fedora-28. If it doesn't happen then it is
a problem between Fedora 28 and the version of Fedora you are trying.

According to the log file on Centos, everything was defaulted or probed.
