Remote Desktop only shows 256 colors

On windows 7 64bit pro desktop.  Using citrix to access a remote location.  Citrix serves out a remote desktop connection app.  When using the remote desktop connection app it only shows one color selection, 256 colors.

This only happens on this one workstation.  It works with other workstations and showing multiple color selections.  I even re-install the OS, got the latest nvidia driver. This workstation has a GeForce GX 480 graphics card.  

How does the remote desktop get the color configurations for the workstation?  Is there something to do with the graphics card/driver?  I do not believe it is a policy blocking or locking it down to 256.

Thanks

I know that setting.  That is the problem.  The setting is only giving me 256 color ONLY.

I was not thinking about this before but I do have a dual monitor setting.

oh my god.  that was the problem.  sorry folks.  I answered my question.  I turned off the second monitor in the properties and logged in and again.  I got multiple color listing now.
maybe it seems stupid but have you checked "hardware acceleration" under display advanced settings?

I do not think i can get to that setting.  When I am in the troubleshoot tab the change setting button is ghosted out.

Is there any way to get this to work with multiple displays?
Try moving from aero to windows classic, does this help ?
did you try updating this OS or the rdp protocol at leaset?
Commented:
OS is patched.  I do not have control over the rdp client.

I think I sort of know what is going on or at least not going on.  I inherited a smaller second monitor which is not the same model and can only display a lower resolution but same color depth and refresh rate.

When both are set to different resolutions remote desktop, for some reason, will only display 256 colors.  When I lower the larger monitor's resolution down to the same resolution as the smaller it did display an extra setting for the color depth besides 256.

I am not sure if there is better solution but I guess this means that when using dual monitors both monitor's resolution must be set the same.
