I decided to trash my Win10 Creator Update development PC and return to Win7 for a more "comfortable" environment. I also had some issues with the Creator Update, which are not relevant now.
I am attempting to establish a remote desktop connection from my Win7 laptop to my Win7 dev box. While the connection will establish, the display will not scale correctly or consistently.
By that I mean, If I boot the PC, then login via RDP, the display is not scaled. If I log into the PC, the display is scaled (I had changed it to 125% via the Display control panel). If remain logged in, then establish an RDP session, I get a properly scaled remote session!
I have tried adjusting the login screen DPI settings to 125%, with no change in behaviour. I did a search through the registry and changed all of the LogPixels settings from 0x60 to 0x78. Even rebooted. No dice - I only get a scaled RDP session if I first log into the remote PC prior to establishing an RDP session.
Clearly, this will be annoying, so, looking for ways to fix. I never had this problem with Server 2012R2.
