Bug description:
  Colour bandind is visible everywhere in the system. I believe it's not
  a hardware problem, since booting with 'nomodeset' works as expected
  and the previously installed Ubuntu 14.04 also worked.

  I tried installing kernel 4.18.0-16.17 from ppa:canonical-kernel-
  team/ppa but the problem remained.

  There were already similar bugs,
  https://bugs.launchpad.net/bugs/1749420 ,
  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1794387 and
  https://bugs.launchpad.net/bugs/1788308, but the fixes provided for
  those bugs did not work for my specific monitor.
