Dual Monitors on Citrix XenApp Server for Windows 2003 (Presentation Server 4.5)

To resolve most issues using dual monitors with seamless published apps, simply change the color setting on the application properties in Access Management Console to 16-bit. Most problems arise from running out of virtual video memory on larger LCD displays in dual mode. If you lower the color setting (an unnoticeable difference) then you have enough memory and voila!

1. Open Access Management Console.
2. Expand Applications under your farm.
3. Right click the app you are having trouble with and click Properties.
4. Click the Appearance heading.
5. Click the drop down under Colors and choose 16-bit instead of 24-bit.
6. Click OK and test!
