Blade workstation—If the sending computer is a blade workstation, then its NVIDIA driver exposes all
display outputs the operating system as if they have monitors attached. The resolutions provided by
the NVIDIA driver cover a broad range of settings and should meet most user needs. If the desired
resolution is not available, see
Adding custom resolutions on Windows on page 48.
●
Virtual workstation—If the sending computer is a virtual workstation with a hypervisor, the NVIDIA
driver presents a single display to the operating system. The resolutions provided by the NVIDIA driver
cover a broad range of settings and should meet most user needs. If you are using a single display at
the receiving computer, no further action is required. If you need to configure additional resolutions
and/or make additional displays available, see
Creating and applying an EDID file on Windows
on page 48.
●
Traditional workstation—If the sending computer is a traditional workstation, then its NVIDIA driver
expects to find a display attached to one or more outputs. When it does, it queries the EDID (Extended
Display Information Data) information from the display for its supported resolutions and makes the
display and resolutions available to the operating system. If you do not have a display attached, the
NVIDIA driver reverts to a single VGA output with basic display resolutions. If you want to rack mount a
workstation of this type in a data center, you need to attach an EDID emulator device to the graphics
card outputs you want to use or provide an EDID file from a display you want to emulate. See
Creating
and applying an EDID file on Windows on page 48 for more information.
Creating and applying an EDID file on Windows
There are software tools available to create and edit an EDID file, but the easiest method is to use an existing
monitor from the receiving side and temporarily attach it to the sending system, which should be Windows-
based with NVIDIA graphics. If you have several different displays that you use on the receiving side, HP
recommends that you capture the EDID information of the one that has the highest display resolution. This
will address all other resolution needs.
To create and apply an EDID file:
1. Attach a monitor to the sending computer.
NOTE: This is not possible with blade workstations that use MXM graphics.
2. Open the NVIDIA Control Panel and click View system topology.
3. Click the EDID link for the port where you connected the monitor.
4. In the Manage EDID dialog box, click Export and save the output to a file.
5. Disconnect the monitor and establish an RGS connection to the sending computer.
6. In the Manage EDID dialog box, click Browse and select the EDID file you created.
7. Under Connector type (video signal), select DisplayPort (Digital).
8. Select the checkboxes for the DisplayPort connectors you want to apply the EDID file to. If you apply the
file to multiple DisplayPort connectors, RGS will be able to support dual-display configurations.
9. Click Load. The EDID information will be applied.
10. Click OK, and then click Cancel to exit the Manage EDID dialog box.
Under the View System Topology screen of the NVIDIA Control Panel, you should now be able to see that an
EDID file has been applied to the DisplayPort connectors that you selected. RGS should now be able to match
the desired screen resolution and display layout.
Adding custom resolutions on Windows
The following steps describe how to add a resolution that is not already supported by the NVIDIA driver:
