This patch is already in Yakkety kernel. It will also be released as a
part of the Xenial HWE kernel in Ubuntu Xenial 16.04.2.

Marking this bug as Invalid for Yakkety and Xenial and direct interested
parties to the Xenial HWE kernel.

Prior to its release in February 2017 it can be tested by installing the
hwe-edge packages. Have a look at this page for more information:

  However it is perfectly valid to use higher pixel clock on some
  graphic cards.

  This patch will allow the end-user to adjust the pixel clock with the hdmimhz kernel parameter until the detection code gets good enough:

  This page contains a lot of useful information and lead me to a sollution to my problem:
  https://www.elstel.org/software/hunt-for-4K-UHD-2160p.html.en

  I think this is worthy of consideration for backport to the Xenial kernel as not being able to use the most recent LTS version of Ubuntu Desktop with current hardware is a drag.
