Multiple Monitor Issue

Hi There

We have a little problem with multiple monitors.

Client: Windows 7 Embedded on HP ThinClients with App Portal

VDI: Windows 7 on Hyper-V with vWorkspace 7.6

Span multiple monitors in full screen is enabled.

Sometimes after logon is complete the second screen is black, only the mousepointer is visible when you move to the second monitor.

Sometimes after logon the desktop is spanned over both monitors perfect.

I think its about 50/50%

For the situation when the desktop is not available on both screens i have the following solution.

After login, go to the blue connection bar at top of the screen, down the client or smart size the window, then go back to full screen and the desktop is well spanned over both monitors.

Any hints ideas, tips or tricks or should i create a spport request?

Thanks in Advanced

Marc

This is the solution

Reduce the Color Depth on the thin client from 32bit to 16bit

or

Create a larger RAM Drive, 96MB instead of 32MB

Thanks, Marc

Hi Cyril,

I've had a read through the case notes and it wasn't the testing in VMware vs HyperV that was the difference it was that you and the engineer tested with multimonitors and everyone else tested without spanning multi-monitors. VMware has the same issue as it is an MS restriction not Hypervisor.

I'll email you through the case.

Thanks, Andrew.

Marc,

Thanks for pointing the KB out. Unfortunately, I don't have a VMware environment to try out. This was being brought up to me by support as they were having issues replicating my issue (aero glass effect) and eventually they found out that their test environment was in VMware where the Aero glass effect shows up properly. You can refer to Service Request # 1057833 for the full log of this.

Regards,
Cyril

Hi Cyril,

I was looking into Marc's issue when I stumbled across your post here.

Just so you know, microsoft state that aeroglass  does not work with multimonitor. http://support.microsoft.com/kb/969084 in rdp7

Aero Glass support

Terminal Services in Windows Server 2008 did not support Aero Glass remoting for sessions. This is now supported in Windows Server 2008 R2 Remote Desktop Services, but is incompatible with multi-monitor support

(Yeah, I know that says 2008r2 and not Win7 but the rules are normally interchangable as they are both RDP7.x)

What did you do to get it working in VMware and are you sure it was dual monitor as I tested it here just now as I thought dual screen worked on my VMware with AeroGlass but I found it is not currently working with dual screens and works perfectly on one.

Thanks, Andrew.

P.S Sorry for highjacking Marc's thread.
