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

Beware that the article mentions to be applicable for PS 4.5 and higher.

Nevertheless we used the settings as described to publish desktops with 
5100*964*16 pixels from PS 4.0 to workstations with 4 screens. We noticed 
however that the relevant setting tends to "reset itself" to 8192 on reboot, 
which required us to implement a startup script to keep it active. All in all 
our experience with large published desktops on PS 4.0 was less than delectable 
and we're looking forward to deploy XenApp 5 for these applications.

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
Ang

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
