Hello Christer,
Thank you for your message.
Please note that RDP is a Microsoft-native solution and Remote Utilities have no control over how exactly it functions and the RDP connection mode that you can see in Remote Utilities Viewer simply runs the Microsoft's RDP client, nothing more.
Here's how you can change the RDP resolution and preserve it every time you connect to a remote Host using RDP:
1. Right-click on the connection in the address book and select
Properties.
2. Navigate to the
RDP tab and click
Configure. This will open the native Microsoft RDC client.
3. Click
Show Options.
4. Navigate to the
Display tab and select the preferred resolution.
5. Get back to the
General tab of the RDP window and press
Save.
6.
Important: Make sure to
close the RDC window (do not press "Connect") and
click OK in the connection properties window - this will save your connection properties for RDP within Remote Utilities, so that the resolution stays the same every time you use the RDP mode:

Hope that helps.
