When you connect via RDP to a server on Windows, Windows automatically selects the resolution and DPI based on what is set on the client.
That is, RDP “mirrors” the client. And if you connect from a machine with high DPI, then RDP will set a high DPI on the server too. Which can interfere with installing some apps (for example).
Moreover, if you simply change the DPI on the client – it will not help immediately. You need to reboot the client, and then reboot the server. Then everything will be mirrored correctly. Well.. that’s essentially what this article is about. You need to change both and.. reboot here and there. Billy the Pervert surprises as usual.
There is also another option:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\IgnoreClientDesktopScaleFactor
DWORD32
Value: 1
