Symptoms

When connecting to an RDS session from a machine which uses a high resolution display, icons and text within the published session are very small in size.

Cause

Since the session is being run remotely at a different resolution, much lower than the resolution used locally, when the resource is mirrored, the same amount of pixels used remotely will be mirrored locally.

As a result, the mirrored content is small in size which may be uncomfortable for some users.

Resolution

Some ways to alleviate such behavior may be:

• In Windows for the user's profile on his RDS session, increase the display size for all items. This is achieved in the Control Panel > Appearance and Personalization > Display

NOTE: In case this option is greyed out with the message

    ***“The display settings can’t be changed from remote session”***

Please review the following Microsoft Technet article: Cannot change the DPI setting through a Remote Desktop session on a computer that is running Windows 7 or Windows Server 2008 R2

• On Windows 8 clients and above, open the windows Parallels 2X RDP client and try to toggle the option "DPI Aware" from the Options menu.
