I had this question after viewing ASA5505 RDP session screen resolution too high
I connect through RDP to a Windows 2008R2 server. The screen resolution when checking on the RDP session matches the setting of my local workstation. The ICON's on the RDP session are very large and when I go into the Display setting the message the I cannot change the screen setting in a remote desktop connection.
How can I alter the setting on my remote desktop session?
