CITRIX APPS : The following requested video mode was not available

My colleague ask me about error from her citrix terminal, when she try to open application from citrix apps, it always show an error like picture below.

"The following requested video mode was not available: 1920 x 1080 x 24 BPP

The video mode has been set to the following mode: 1847 x 1038 x 24 BPP

Video mode restricted by administrator. " 

This was due to the fact that not enough memory had been allocated to the graphics for individual client sessions to support the resolution on larger monitors.
