I have tested the display with both type of kernels. Unfortunately I see
no change.

Test1: Ubuntu Trusty Tahr with Ubuntu kernel 3.12.0-3-generic
Actual result: The original error message displayed by the monitor.
Expected result: Display Ubuntu desktop in 1920x1080@60Hz.

Test2: Ubuntu Trusty Tahr with mainline kernel 3.12.1-031201-generic
Actual result: The original error message displayed by the monitor.
Expected result: Display Ubuntu desktop in 1920x1080@60Hz.

A fresh dmesg output is attached.

If you need additional information, let me know!

Title:
  External monitor on display port has no sync with radeon driver

Status in The Linux Kernel:
  Confirmed
Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  When I turn on the external monitor, it displays an error message:
  "The current input timing is not supported by the monitor display.
  Please change your input timing to 1920x1080@60Hz or any other monitor listed timing as per the monitor specifications."

  The GNOME display settings dialog shows exacty this recommended setting as current.
  I even tried to set it up using xrand with:
  $ xrandr --output DisplayPort-0 --auto -s 24/1920x1080 -r 60

  $ xrandr -q
