Hi

I've got a 24" monitor at home running at 1920x1200, and I can connect
to a XenApp 4.5 / Server 2003 Citrix farm at the office and run
seamless apps at the full resolution without issues. The Citrix ICA
session is only limited by the amount of Video RAM that's configured
in the Citrix Farm. Right Click on the Farm properties in the AMC,
Server Default/ICA/Display and increase maximum video RAM to 8192 (all
values are MB). XenApp 5/Server 2008 defaults to 32768 (MB)

Regards

Ken Z

forgot to mention that the default Video RAM on a Windows Server
2003/XenApp 4.5 is 5625 MB.

A screen resolution of 1600x900 at 32 bits per pixel works out as

1600 x 900 x 4 = 5760000 = 5625 MB

exactly at the limit of the video RAM (the reason you multiply by 4 is
becuase 32 bits per pixel requires 4 bytes of video RAM).

Running at 1680 x 1050 at 32 bits per pixel works out as

1680 x 1050 x 4 = 7056000 = 6891 MB

this pushes the video RAM requirement past the factory default
settings. My guess is that the hosting company has left this setting
at the default value.

If you run the app at 24bit colour (3 bytes per pixel)...

1680 x 1050 x 3 = 5292000 = 5168 MB

This should fix within the default video RAM
