Remarks

A MetaFrame XP server can be set to inherit its ICA display settings from the server farm ICA display settings. Use /query to display the current inherit settings.If /inherit is on, the settings displayed with /query are the server farm settings.

When /inherit is off, the settings shown are for the current server only.

Twconfigcan be used only to change the settings on this server, for this server. To change the settings for another server or for the server farm, use Citrix Management Console.

Within the maxmemlimit, various combinations of session size and color depth are available. The session size and color depth values are determined using the following formula:

height x width x depth = maxmem,

where the height andwidthare measured in pixels anddepth is the color depth in bytes according to the following table: The following is a list of the maximum session sizes with a 4:3 aspect ratio for each color depth at the default maxmemvalue (height by width by color depth):
