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 le has been applied to the DisplayPort connectors that you selected. RGS should now be able to match
the desired display resolution and display layout.
Adding custom resolutions
The following steps describe how to add a resolution that is not already supported by the NVIDIA driver:
1. Open the NVIDIA Control Panel and click Change Resolution.
2. Click Customize.
NOTE: The rst time you do this you might see a warning—accept it.
3. Enable the Enable resolutions not exposed by the display checkbox, and then click Create Custom
Resolution.
4. Add the desired custom resolutions.
Matching display resolution and layout (Linux-based sender)
If the Match Receiver display resolution option is enabled (see Connection on page 19), RGS automatically
tries to set the resolution and display layout of the sender to match that of the receiver. Because RGS
supports a single remote X screen only, it tries to set the resolution of the sender to the combined resolution
of all displays attached to the receiver.
For example, if the receiver has dual-monitors set at a 1280x1024 resolution, RGS asks the sender to set its
resolution to 2560x1024. If the resolution is not supported, RGS instead uses the preferred resolution of the
sender from the le xorg.conf.
The easiest way to check if the sender can match the receiver resolution is to attempt to set the resolution on
the sender manually. If you can set the resolution manually, then RGS can do it for you automatically. If you
cannot set the resolution manually, you must modify the le xorg.conf to support the additional required
resolutions.
To test if you can match the resolution manually, establish an RGS connection with the following connection
settings disabled:
●
Match Receiver display resolution
●
Match Receiver display layout
NOTE: This setting should always be disabled when connecting to RGS Sender on Linux.
Once you establish an RGS session, open an X terminal window and use the xrandr tool to list all the
currently supported resolutions for the X server. The tool can also be used to congure the X server display
settings, including size and orientation.
Previous releases of the X Window System used the le /etc/X11/xorg.conf to store initial setup
information. When a change occurred with the monitor or video card, you were required to edit the
le
manually. Although current releases of Red Hat® Enterprise Linux® (RHEL) have largely automated the
process, you still need to edit the le to support congurations where no monitor is attached or where you
want the X server to simulate that it has a dierent monitor attached to it with dierent resolution
capabilities. Similarly, this is also the case when you want to match the receiver’s resolution in an RGS session
where the X server cannot determine the capabilities of the receiver’s monitors.
