I have also verified unity-settings-daemon
15.04.1+16.04.20160701-0ubuntu3 for Xenial.

After connecting a faulty-EDID display - I saw the product name. With a
display device with correct dimensions in EDID - screen diagonal in
inches was displayed.

Bug description:
  [Impact]

   * There is a number of display devices that misuse the width & height field 
in EDID. Instead of real size in centimeters it contains encoded aspect ratio 
(e.g. 1600x900, 16x10, 160x90).
  This leads to incorrect calculation of diagonal for the purpose of e.g. Unity 
settings app.

  [Test Case]

   1. Connect a display device that provides incorrect EDID data (e.g. LG 
49UB850T-DA TV).
   2. Open the Displays section of Unity settings.
   3. Look for the name of the newly connected display in the settings window.

  Expected result:
  Display name should contain its real diagonal or model name (if dimensions 
are not availabe).

  Actual result:
  Display name contains a ridiculous diagonal (e.g. 72" in case of a 49" 
display).

  [Regression Potential]

   * This affects the way the display name will be formatted for any
  software using unity-settings-daemon. If anything is testing/comparing
  display names - it may fail.

  [Other Info]

  * Original bug description:

  After connecting a LG 49UB850T-DA TV the following information is
  displayed in the unity-control-center: Goldstar Company Ltd 72"

  It's misleading since neither the company name nor the diagonal
  matches.
