I am using the Citrix Receiver in Windows 8, and on Windows XP on another PC. I often log into work from home and am unable to span the session to dual monitors like one can easily do when using "mstsc" (Remote Desktop) by using "mstsc /span". Can this be achieved with either setting options on the server (Citrix server) or on the machines the client (Citrix Receiver) is installed on? I don't have access to the server, but if there is a way, I can put in an employee request for this.

Wouldn't your IT department be a better target for this question? –  joeqwerty Apr 13 '14 at 4:30
I asked them several months ago. They didn't know. –  MacGyver Apr 13 '14 at 4:41
So they said they didn't know and didn't take up the task of finding out? That's horrible. That's why IT people get a bad name. –  joeqwerty Apr 13 '14 at 4:44
You might want to contact your reseller or Citrix directly, since Citrix isn't cheap and for what you're paying they ought to give you more than MacDonald's free smiles. –  Guy Hughes Apr 13 '14 at 5:39

I figured this out. If you installed the Citrix Receiver, and have the browser plugin, you will need to disable that plugin so that a *.ica file does not launch automatically with the ICA Client when it finishes downloading.

Edit the file in a text editor and change the TWIMode=Off, to TWIMode=On. This will allow the window to span to both monitors. The monitors need to be the same size, and the resolution also needs to be the same on both monitors. Save the file. Then run the file (note: for the first time). The file becomes obsolete the second time you run it because the authentication token expires on the server.


Google Chrome Menu > click "Settings" > click "show advanced settings" blue hyperlink > click "Content Settings" button > click "Disable individual plug-ins" blue hyperlink > then toggle "Enable" / "Disable" blue hyperlinks for the Citrix ICA Client plugin (name might be different depending on version)

Thanks for your post and good to know it works for you. But can you elaborate a bit on how you disabled the plugin and where you accessed the *.ica file? Thanks again. –  squashed.bugaboo Apr 14 at 20:41
It's kind of deep in settings.. see my update –  MacGyver Apr 14 at 20:50
By disabling that plugin, it doesn't automatically launch the *.ica file. If it doesn't launch, the authentication key won't expire until you launch it at least once. So once you disable it, edit the file, then save it, and then open the *.ica file manually. You can hack a lot of things with the application that launches in the Citrix Farm with this method. It's very useful for troubleshooting. –  MacGyver Apr 14 at 20:54
Great.. I will give it a try. Thanks for the update. –  squashed.bugaboo Apr 14 at 21:13
I am using IE 11 actually..and even though I disabled the Citrix ICA client plugin as you mentioned, it doesn't let me save the .ica file. It loads it way too quickly for me to do anything. If I knew where I could go in C:\Program Files (x86)\Citrix to edit it, it might help..looked but couldn't find a .ica file. –  squashed.bugaboo Apr 15 at 3:37

Once connected to remote desktop, drag Citrix window across both monitors. Press the maximize button, the client will maximize to both screens and be presented as a dual-monitor setup.

What version are you on? –  MacGyver Sep 10 '14 at 22:53

On a MAC, it's easy as dragging the corner of the desktop window across monitors. For Windows, is much more cumbersome. On the Citrix Receiver icon at the top left corner of the Desktop window, click on resize session, select Full Screen for Desktop Size. To get out of Full Screen mode do a SHIFT+F2 If anybody know a better way, please post Thanks

I am running on Windows, but hopefully your post is useful to others. In our particular default *.ica configuration, the window size is locked. –  MacGyver Sep 25 '14 at 22:27
