Nvidia Offloading Card
Q: When do I need Nvidia Offload Card?
If you need more than 9 1080p displays you will need a support nvidia card for GPU offloading. Nvidia offload card renders higher video and image quality in a scaled video wall with substantial improvement in synchronization. Furthermore, Nvidia offload card frees more than 50% CPU resources by taking workload of CPU.
Q: What are the compatible Nvidia Offload Cards?
See the list of certified cards. In addition, other 700 and 900 series Nvidia cards may also work.
Q: Can I use GeForce GT 620 Nvidia Offload Card?
Nvidia GeForce GT 620 theoretically supports just one 1080p display where as Intel's integrated GPU can support 9 displays. That is why any card lower than GeForce GTX 750 (which can support 16 displays) is not recommended.
Q: How do I install and enable the Nvidia Offload Card?
- Make sue you have a supported Nvidia card installed in a supported host PC/server
- Set default GPU in the BIOS of the host PC/server to the Intel® integrated GPU (not all BIOS support this option)
- Must NOT plug any display into the Nvidia GPU, only plug into Intel integrated GPU
- Go to Control Center > System Operations > Nvidia Offload Card and enable the Nvidia Offload Card Support
Note: You will need a special license key to enable Nvidia offload card support. See Nvidia Offload Support for more details.
Q: Do I need to restart the host PC/server after enabling or disabling the Nvidia Offload Card Support?
No, you do not need to restart the host PC/server. You need to relaunch the video wall or standalone station. To do so, go to Control Center > Station Mapping and unmap a stand alone station and remap it.
Q: How do I see if Nvidia Offload Card is being used or not?
Visually you can see the difference in content rendering and synchronization. Also, from Control Center > System Operations > Nvidia Offload Card you can see if the option is enabled or not. In addition, you can check CPU usage from the terminal by using
top command, given your setup have enough displays.
While most Userful deployments work fine with over a gigabit network (including a gigabit uplink between server and switch); for high resolution content (6k source content) or larger numbers of displays, or if you are doing server-side content upscaling (as opposed to using the display's built-in scaler -- which is more efficient with CPU and bandwidth), the pixels throughput may demand a 10gig network card on the PC and a 10Gig uplink port on the switch. When playing content at 30fps a 10Gig uplink (between host and switch) will be required if:
- the source content is 6k resolution or higher, or
- you are driving more than 25 displays (if those displays are using display side scaling), or
- you are driving more than 12 or 13 displays (with server side scaling or native 1080p playback) which sends full 1080p resolution to each display over the network
Note: Only the uplink port of the switch needs to support 10Gig, the remaining ports which connect to the zero clients can be gigabit. Before finalizing the components of your deployment, contact your Userful representative.
