This is a follow up to http://communities.vmware.com/message/1642640#1642640 (Cannot change font size View 4.5 client, November 8, 2010). The posting is obsolete at this point, is a bit confusing and doesn't seem to apply to Windows 7 desktops at all.
Cross-Post Update : Just found an unanswered similar post at View, Windows 7, PCoIP can't change font size
We are using VMware Horizon View 5.2 with WYSE P25 Zero Clients (PCoIP) and I am able to reproduce the same problem while connecting to the View Connection Server with the standard VMware View Client, version 5.2. The virtual desktop is a member of a Windows 2008 R2 Active Directory Domain.
I have painstakingly made sure that both GPO's shown below are actually being applied to the desired user and computer at the View Virtual machine in question and it still will not allow the user to modify the "Appearance and Personalization->Display" settings from Smaller - 100% (default) to Medium or Larger because they are all grayed-out. I am sure there is a policy setting buried somewhere, or another policy setting that I need to Enable/Disable, but I cannot find it.
The logged in user for the Virtual Desktop is also a member of the Local Administrators Group, and I modeled the Group as shown above to make sure the policies were being applied correctly. Lastly, there is a claim/reference in the post (Cannot change font size View 4.5 client, November 8, 2010)mentioned above that claims the solution is to Disable the GPO found at "User Configuration/Policies/Administrative Templates/Control Panel/Personalization/Prohibit Selection of Visual Font Size". This policy does not seem to apply to Windows 7 machines, so naturally it does not show up above (even though I defined it).
