How can I change (increase) the DPI of a remote desktop session?

I am using two Windows 7 PC - both are already set to 125% on Control Panel/Display/Make it easier to read.

Yet when I open a Remote Desktop from one machine to the other the remote desktop is displayed at 100% (tiny).

How can I have the Remote Desktop displayed at 125%?

  • The only way to make remote picture bigger I found is to set lower resolution for the local PC's (client's) monitor (which looks ugly to be honest). My case: Win 7 (client) connects to the remote headless Win 10. – Lu55 Apr 16 '18 at 23:02

I eventually found a solution to this via this blog post by Falafel Softare.

Basically:

  • Download Microsoft's souped-up RDP client called Remote Desktop Connection Manager 2.2 (edit: no longer available so try your luck with Remote Desktop Connection Manager 2.7 - see notes below)
  • When you add a new server, go to the 'Remote Desktop Settings' tab of the Properties and select 'Same as client area'
  • Remote Desktop Connection Manager will then display the remote machine using the client machines DPI settings.

I've written this up in a bit more detail with screenshots on my blog.

edit: Sounds like this might only work with Windows 8 clients, getting reports it doesn't work the same way with Windows 7 clients.

edit: Microsoft is no longer offering V2.2, only V2.7. Sounds like it will still work if you tweak the settings: Browse to the location of RDCMan.exe. (C:\Program Files (x86)\Microsoft\Remote Desktop Connection Manager by default). Right click RDCMan.exe select properties, select Compatibility tab and uncheck "Disable display scaling on high DPI settings"

    Does not appear to work when using Windows 7 as the client, at least in my experience. The referenced blog post has more info. It sounds like Win8 vs Win7 might be an important variable. – Cameron Mar 2 '15 at 18:54
  • Using Remote Desktop Connection Manager v2.7, along with the settings fix worked for me. (Win 10 RDP into Win 7). Note: I had installed the hotfix mentioned by Yngvar Johnsen first (on the Win 7 machine), so not sure if that helped or not. – Johnie Karr Mar 7 '16 at 0:51
  • Win 10 RDP into Win 7 (without the hotfix) works as promised. If i understand the hotfix alternative correctly, this is a better solution as there is no manual manipulation of the DPI setting and RDCMan is a better way to RDP anyway – KCD Jun 28 '16 at 22:10
  • "select Compatibility tab and uncheck "Disable display scaling on high DPI settings" - this worked for me without installing the fix on remote – user3526 Jul 19 '16 at 13:51
  • This actually works for me using Win 7 client - Win 7 remote. Installed hotfix on remote, set scaling on remote to 125% and the normal Win 7 rdp client now displays the scaled session properly. Thanks! – Jon Jul 25 '17 at 14:06

Microsoft has released a hotfix enabling the DPI setting for RDP sessions.
Hotfix info: http://support.microsoft.com/kb/2726399.
Hotfix downloads:

32-bit: http://hotfixv4.microsoft.com/Windows%207/Windows%20Server2008%20R2%20SP1/sp2/Fix396134/7600/free/451040_intl_i386_zip.exe

64-bit: https://hotfixv4.trafficmanager.net/Windows%207/Windows%20Server2008%20R2%20SP1/sp2/Fix396134/7600/free/451041_intl_x64_zip.exe

Also note that you have to manually either choose to open this file as administrator, or choose a different unzip location. Then run the smaller file that comes out, which will automatically elevate as it should.

  • Presumably you install this on the destination machine rather than the one you are remoting from? – codeulike Nov 7 '13 at 16:00

    To answer myself: Yes, install the hotfix on the remote machine. – codeulike Nov 7 '13 at 19:18
  • In case you are leary of hotfixes, this one is dated July 19, 2012. One would hope it is stable or MS would have pulled or updated it. – JohnC Feb 18 '14 at 11:26

I know this is an old question, but I have found and elegant and easy solution to this issue.

Change Text Size is a small application written by Michel Stevelmans which will allow a user to change their DPI settings. I have tested it on Windows 7 and it has worked wonderfully.

Here is a link to the KBB article in regards to this issue: KB2544872

    Themed font sizes are not the same as the DPI setting. DPI affects more than window metrics and system default font sizes. – Chris Smith Nov 16 '12 at 15:03
  • Michel Stevelmans works like a charm. – Martin Feb 22 '16 at 14:32
