Supported Desktop Resolution with HDX 3D Pro in XenDesktop
While connecting the client requests desktop with certain size [resolution example. 1920x1200], which should be supported by the GPU on server [Virtual Delivery Agent] and by the monitor attached to the VirtualDeliveryAgent [VDA]. If there is no monitor attached on VDA, then it should be present in the set of resolutions supported by the GPU. If the matching resolution is found, then the desktop with that resolution is given, else the desktop with the nearest supported resolution is given.
In some cases, the use case might require a specific desktop resolution, for example 1440x900, which is not available at the VDA side then it can be added as a custom resolution in the GPU control panel on VDA. If the GPU on the VDA accepts this custom resolution then it is available for the next connection.
When users try to connect from any tablets, the screen resolution of the tablet should be known. Once the resolution is identified, they must check on the VDA side to see if it is available. If the resolution is not available, then add a custom resolution in the GPU control panel on VDA.
Changing the desktop resolution within the session is not supported. If the resolution change is required then following procedure should be used:
If the desktop is in full screen mode then change the client local screen resolution, disconnect and reconnect.
If the desktop is in windowed mode, then resize the desktop window to the desired size, disconnect, and reconnect to get the desired desktop resolution.
Multi-Monitor Configuration
It is important to note that for HDX 3D Pro in multi-monitor case, the following condition should be satisfied: number of Monitors on VDA >= No of monitors on client. So, for dual monitor desktop, VDA should have two or more monitors attached. These monitors can be physical or virtual. The virtual monitors can be configured in NVIDIA control panel for Quadro and Quadro FX cards using forced Extended Display Identification Data [EDID] option.
Procedure to configure virtual monitors using Forced EDID is mentioned in the Configuring Virtual Monitors section.
On first connection, the desktop might be displayed in the single monitor mode only. To get true multi-monitor desktop, move the desktop window across 2 monitors on client and maximize the desktop using desktop viewer toolbar at the top so that it spans across two monitors. Now disconnect and reconnect the desktop. On reconnect, the desktop displays in true multi-monitor mode.
Configuring Virtual Monitors
Virtual monitors can be configured for VDA on physical machine with NVIDIA GPU and for Virtual Machine on XenServer 6 with NVIDIA GPU assigned to it. Following procedure explains how to add multiple virtual monitors:Step 1: Getting Monitor EDID Files
Complete the following procedure to get Monitor EDID file:Exporting EDID from NVIDIA control panel:
Attach the desired monitor to the GPU for which the EDID file is required.
Install the latest NVIDIA driver and restart.
Right-click on the desktop and select NVIDIA Control Panel.
Under Display, select Run multiple display wizard.
Note: Select this option only when View system topology is not visible.
Select View system topology from Workstation.
Select active Monitor.
Clicking on the active Monitor displays the following screen:
Click Export EDID.
Save the Monitor EDID information in the text format, as displayed in the following screen shot:
Step 2: Importing EDID File to Create Virtual Monitor
After the EDID file is available, it can be used to create the virtual monitors.
Complete the following procedure to import the EDID file in the NVIDIA control panel:
Right-click on the desktop and open NVIDIA Control Panel.
Select View system topology from Workstation
Click on the monitor that is in Not connected state, as displayed in the following screen shot:
Ensure to choose the appropriate Connector type.
Click Load EDID and select the appropriate EDID file.
Once the EDID loading is successful, the following message is displayed:
Monitor_EDID.txt EDID successfully loaded.Click OK.
After the virtual monitors are configured using the Forced EDID, the final status is as displayed in the following screen shot:
Note: This way by creating virtual monitors on VDA [Physical Machine or Virtual Machine], HDX 3D Pro desktop can be used in multi-monitor mode.
