Yes, this is strange. Did you try to fiddle with the setup of the monitor using
the buttons at the monitor? Something like scaling options?
I have no idea why xrandr doesn't show the native resolution.
The wiki of archlinux is a good documention. See "Adding undetected resolutions" on
https://wiki.archlinux.org/index.php/xrandr#Adding_undetected_resolutions

something like

  xrandr --newmode "2569x1080_66.7" 185.6 2560 2624 2688 2784  1080 1083 1093
1111 -hsync -vsync
  xrandr --addmode "2569x1080_66.7"
  xrandr --output HDMI-0 "2569x1080_66.7"

using information from your Xorg.0.log

>> Which kernel packages ("linux-image*") are installed?

Which one is running?
  uname -a

May I ask, which CPU you have?

No. It's just that I#m more familiar with aptitude CLI for package management,
then I would have commanded
  aptitude unmarkauto xserver-xorg-video-ati
  aptitude purge xserver-xorg-video-all
  aptitude purge '~c'

The last command purges remains of removed packages.
