Frequently Asked Questions¶
Can I use a screensaver?¶
Yes. However, a blank, static screensaver will provide the most efficient CPU ane network bandwidth usage.
Why can't I use the maximum number of monitors or monitor resolution?¶
GPU profile licensing, GPUs, or clients may limit monitor resolution and monitor count, which will prevent you from utilizing the full agent specification. For more information, see supported displays.
Which graphics rendering APIs are supported?¶
The Graphics Agent captures and delivers the output from the GPU, which is responsible for providing rendering APIs like OpenGL. See the documentation for your GPU for more information about rendering APIs.
How quickly does a PCoIP agent complete a connection?¶
PCoIP agents can usually achieve a connection in 15 to 30 seconds. We use the statistical value Top Percentile (TP) to measure the time to establish a session:
- TP99: Ninety-nine percent of connections complete in under 30 seconds.
- TP50: Fifty percent of connections complete in under 15 seconds.
What do I need to know about power management?¶
Hosts with Windows power management enabled may drop PCoIP connections when turning off displays or going to sleep. If this behavior is undesirable, these Windows power management features should be turned off.
To disable Windows power management features:
- From the Windows Control Panel, open Power Options.
- Click Change plan settings next to the enabled power plan.
- Select Never from the drop-down list for Turn off the display
- Select Never in the drop-down list for Put the computer to sleep.
- Click Save changes.
Why am I seeing black bars?¶
Black bars may appear around the outside of your desktop when there is a mismatch between the supported resolutions on the host side and the client monitors. This is only applicable when the PCoIP Graphics Agent is not able to successfully initialize or communicate with the NVIDIA GPU via the Grid APIs. For more information, see Handling GRID Configuration Problems.
Why is my display topology broken after upgrading my GRID card?¶
If you upgrade your NVIDIA graphics card to a new supported GRID driver version after installing the Graphics Agent, the NVIDIA Capture SDK may need to be manually re-enabled.
Why is my application not sending audio?¶
The PCoIP agent delivers audio over PCoIP connections by reassigning the system's default audio device. Only applications that use the system default audio device will send or receive audio over PCoIP; applications that are configured to use non-default devices will not work. If you don't hear audio from your application, make sure it is configured to use the system default audio device.
I'm using Teradici Cloud Licensing. What network blocks should I leave open?¶
If you are using Teradici Cloud Licensing, you must add the following to your allowlist:
If you use an IP-based allowlist, add the following network blocks to your allowlist:
IPv4: 220.127.116.11/27 IPv6: 2620:122:f005::/56
Important: Migrating from the previous specification
Previously, our allowlist specification looked like this:
Production: 18.104.22.168/24 Disaster Recovery: 22.214.171.124/24
If you have an existing implementation using an IP-based allowlist like this, we recommend you leave it in place until the new allowlist is active and tested.
