[THIN] Re: FW: ICA Multiple screen support Issue

The max color depth for ICA is 24-bit so the multiplier is 3, not 4.

 

This article answers your multi-monitor questions. There is a reg key that allows you to specify graphics memory beyond 8192.

I'm not sure how ICA handles multi-monitor with different resolutions on each monitor.

Hi

Further to this, if I set all 3 monitors to 1024*768, all 3 monitors work fine.  If I set all 3 monitors to 1440*900 the third monitor doesnt work.  It looks like there is a max resolution limit or the session is running out of graphics memory.

How can I check to see how much Display memory is in use?.  I changed the Farm setting "Maximum memory to use for each session's graphics" to the max which is 8192 but I continue to have the issue when working on the max resolution.

Thanks

Hi

We have some users that have 3 monitors.  When running Published Applications, we find that 2 of the monitors work but the third does not.  You cannot drag a Published Application into the third monitor.  The first 2 monitors are fine but the third is ignored.  The monitor config is as follows:

19" Monitor (1440 x 900 x 32)
19" Monitor (1440 x 900 x 32)
17" Monitor (1280 x 1024 x 32)

We have not changed the default ICA Display memory allocation.  Farm setting "Maximum memory to use for each session's graphics" is set to
5625 kilobytes. 

Im not sure if the ICA session is running out of memory.  Where can I see the session memory usage?  Based on articles Ive seen, you can determine the memory requirements by:

1440 x 900 x 4 = 5184000
1440 x 900 x 4 = 5184000
1280 x 1024 x 4 =  5242880

Based on this calculation these sessions would require 14Mb.  Am on the right track with this?  Im currently running Citrix Presentation Server 4 on Windows 2003.  ICA Web Client version is 10.150.  Can anyone suggest any other changes apart from upping the graphics memory to 14Mb in trying to resolve this issue where I cannot drag to the third screen?

Thanks
Ang
