System affected
Citrix Virtual Lab - all applications - Windows clients
Description of Error
When using Citrix Workspace app on Windows machines where you have multiple monitors connected one of which that has a different screen resolution than the others, the apps you launch through Citrix do not work properly. You may notice that the application windows are off-centered and look strange. Also the application may not respond to mouse clicks because the cursor is offset and actually clicking things to the left or right of where your mouse cursor actually is.
Solution
Method 1 (Preferred):
Change the resolution settings in the Citrix Workspace desktop app.
- Launch the Citrix Workspace app either from your start menu OR by navigating to https://citrix.msudenver.edu/Citrix/StoreFrontWeb/ in a web browser, logging in, detecting the receiver and launching an application from the catalog.

- Find the Citrix icon in your taskbar near the lower right-hand corner of your screen by the clock.

- Right-click the icon.

- Click Advanced Preferences.

- Choose High DPI from the list of options.

- Exit the Citrix app by right-clicking the icon in the taskbar and selecting Exit.

- Re-launch the Citrix Workspace app again and try running your application from the catalog again.
Method 2:
Use the light version of Citrix Workspace
- When navigating to https://citrix.msudenver.edu/Citrix/StoreFrontWeb/ in a web browser and you reach the following screen, select Use light version. Ignore the following steps if you reach this screen.

- If you have already setup the Citrix desktop app using the "Detect Receiver" option in a previous session and are seeing the application catalog instead, use the preferences menu to change your receiver option so you can select the light version.
- Click the cog icon in the top right-hand corner of the Citrix homepage after you have logged in.
- Select Account Settings.

- Select Change Citrix Receiver at the bottom.

- Select Use light version.

- Your applications will now open in the web browser instead of the desktop app.
