Title:
  Experimental setting to enable fractional Hi-DPI scaling offers no
  option larger than 200% on 15.6 inch, 3840 x 2160 pixel display (Dell
  XPS 15 9575)

Status in gnome-control-center package in Ubuntu:
  Fix Released
Status in gnome-control-center source package in Focal:

Bug description:
  [ Impact ]

  On my laptop's 15.6 inch, 3840 x 2160 pixel (282 PPI) display, the
  available scaling options in the gnome-control-center display settings
  are limited to 100, 200, 300, and 400%. This is insufficient as 200%
  is too small and 300% is too large. The missing fractional scaling
  options are dealt with in bug #1687246. However, the currently
  available experimental feature to enable fractional scaling (provided
  in the bug description of #1687246) does not solve the problem on my
  machine:

  gsettings set org.gnome.mutter experimental-features "['scale-monitor-
  framebuffer']"

  After applying and rebooting, the options offered change to 100, 125,
  150, 175, and 200%. Note that there is no value larger than 200% which
  is too small on this display at least for me.

  In addition, the 25% steps enabled by the experimental option seem too
  far apart. With 200%, I am using a font scaling value in Gnome Tweaks
  of 1.20, so I suppose a fractional scaling of approx 240% would be
  equivalent.

  In bug #1687246, Daniel van Vugt (vanvugt) advised to open a new bug
  for gnome-control-center and added that "gnome-control-center seems to
  limit the scale to 200% on some machines, 300% on others. And I think
  I have seen 400% offered in some cases. I don't know why, but the
  inconsistency is definitely annoying."

  [ Test case ]

  In a setup with a display with HighDPi resolution (higher than 2880x1800)
   - Open gnome-control-center display panel
   - Scaling should show 5 level buttons to select
   - Selecting higher values will show all the selectable values closer to the 
chosen one
   - Any value could be used from 100% up to 400% (maximum varies on resolution)

  [ Regression potential ]

  Control center won't show any scaling value, or scaling value may be
  wrong.
