How to transfer DPI settings to a Windows Terminal server?


We have a situation where we are preparing to use a new application.  The application can only be viewed correctly in 1024 X 768.  Our users that use 800 x 600 stated that changing their resolution to 1024 x 768 is hurting their eyes.  Please see the last experts question that I created about this issue for more background:

I think I may have found a work-around:

This hot fix will allow a changed DPI from a host PC to be transferred to a Remote Desktop PC.  If I change the resolution on the host PC to 1024 x 768 and then change the DPI to 200% The other application that was too small is a lot bigger and more readable to the users.  Equally important the new application seems to be un-changed it is still readable and fits in the 1024 x 768 screen. The problem is when I do a remote desktop the DPI settings are not transferred to the Remote Dsktop session.

I then installed this hotfix on 1 PC (Windows 7 Professional) and since thsi hotfix is still being tested I have not installed it on the Citrix Server yet (Windows Server 2008 R2); but, when I did a remote desktop there was no change in appearance of the applications in the remote desktop sessions.

I wonder if I will have to install this hotfix on the Widows 2008 R2 server as well?  Is anyone familiar with this hot fix ( KB Article Number(s): 2726399 )?  it appears that some more experimentation is required.  I can try to spin up a new Windows Server 2008 R2 VM and try to test this theory out with Remote Desktop.

Any ideas?

One problem is that the thin clients that these users are using has Windows 7 Embedded installed on them.  I am not sure that this hot fix will work on Windows 7 embedded.

This may be a non-issue; but it would be good to know if we need to get this installed on the Server as well to work.

The following article provides some interesting reading with Windows 2012 Server and DPI settings.

I wonder if this will work in Windows Server 2012?
This hotfix needs to be installed on the computer/server you are connecting to, not the client.

That makes sense; but, how do you know.  Is it listed in the document?

I will create a test server and see how RDP works on it.  I will also see what happens when I RDP to the test server from one of the Thin clients that has Windows embedded installed on it.

Equally important, I want to test if it is easy to un-install the hotfix after it is installed.  And if there are any side affects (performance or application viewing problems).

I installed the hot fix on a test 2008 R2 server and the hot fix allows the remote user to change the DPI settings, when they are logged on via remote desktop.  The hot fix does not automatically transfer the already set DPI settings from the original PC.

That was what I was looking for because after you change the settings while logged on remote you are prompted to log off your remote connection.  Equally important once the DPI settings are changed to be bigger on the remote connection, the required application that needs a 1024 x 768 resolution can no longer be seen on the screen.  This option has proven to not provide what we were looking for.

it appears that the only legitimate solution is to replace some already existing the monitors(22") larger monitors(27").  Or just have the users deal with the situation on their own.
