RDCMan Scaling Is Blurry: Fix In 3 Steps

RDCMan Scaling Is Blurry: I’m currently using RDCM 2.7 or later and facing an issue where I can’t view the remote server screen properly. My monitors are pretty large and high resolution, which causes the client area to automatically adjust to 2474×995 (optional).

This above setting works fine until the remote desktop appears, and then I’m unable to see anything clearly on it. I’ve tried tweaking the display and client area settings in various ways, but it either results in the screen being too small or no change at all when it comes to RDCMan Scaling Is Blurry.

Client Area Setting

The first thing you have check is with client scaling is properly configured or not, if there are some changes in the global level client arear make sure that is applied to all the parent groups. In below image you can see that I have opened my global setting and when I make any changes here it applies to all of my servers and groups.

Make sure you have same as me if you follow this TSG and if you know to play with this then please check the other options as TGS’s. Make sure all you server groups and VM’s follow “Inherit from parent/source” is enabled if so, the default setting will be applied.

Display Settings

The other which is must thing to check is display settings, now the key feature of this setting is to maintain the scaling and view options which will be applied to RDCMan Scaling Is Blurry by default. So make sure it set to “Scale to fit windows“/”No Scaling“. Now similar to “Client Area Setting” you have make sure it is applied to all the parent groups and VM’s.

DPI settings

To fix your issue, try adjusting the DPI settings via the RDCMan shortcut or .exe properties:

  1. Right-click the RDCMan icon on your taskbar or start menu, then go to Properties (you might need to right-click twice to see ‘Properties’).
  2. Go to the Compatibility tab.
  3. Select “Change high DPI settings”.
  4. Deselect “Override high DPI scaling behavior”. By default, it’s selected with “Application” as the scaling method. It might seem like leaving it checked would do the trick, but actually, unchecking it is what you need.

Option 1: If you use old/earlier server with RDCMan older versions and make sure you check this below option. If you can’t see then follow the option 2 for latest versions of RDCMan & Windows.

Step 2: Check the option where it says, “Override high DPI scaling behavior” and then hit apply/ok.

Once you’ve done that, close and reopen RDCMan. Your client area should now expand to fill the window. Just to clarify, I’m using a 4K Monitor (2840×1160) and RDP into my Azure VMs at 1120×780. Initially, my client area was around 2474×995, making my RDP sessions appear small and centered. However, after applying this fix, the client area significantly reduced, and my RDP sessions now scale to fill the RDCMan window and the RDCMan Scaling Is Blurry problem is fixed.
