: By default, Userful host is configured to use display scaling, it uses the built-in scalar within the display to improve the image quality. Almost all displays have a built-in scalar that convert incoming sources to fit their output display size. You can switch to "server-side" scaling by disabling this option, provided you have a Nvidia Offload Card installed and enabled.

Introduction

Userful™ software appliance allow users to use or enable various system-level settings to create high quality video walls with better content synchronization to yield optimal performance.

Performance Settings

Performance Settings
  • Enable Direct Sync
By default, Userful host is configured to use "Direct Sync", this feature improves the content synchronization across displays in a standalone configuration or in a video wall setup and frees up CPU. It prevents display IDs and message from being displayed during video playback thus avoiding distractions during playback.
  • Nvidia Offload Card Support
Enabling "Nvidia Support" offloads more than 50% workload of the CPU to the Nvidia GPU card. Userful™ supports Nvidia offload support, that enables the administrators to create bigger and high quality video wall with better content synchronization. For more details, visit Nvidia Offload Support page.
Note: Nvidia Offload Card Support can only be enabled if Direct Sync is enabled.
  • Enable 60 fps: Enable this feature for better content synchronization. It can only be enabled if Nvidia Offload Support is enabled.
Note: Userful recommends using a 10Gig NIC and a switch with a 10Gbps uplink port, as switching to 60 fps increases the network bandwidth.
  • Display Scaling
By default, Userful host is configured to use display scaling, it uses the built-in scalar within the display to improve the image quality. Almost all displays have a built-in scalar that convert incoming sources to fit their output display size. You can switch to "server-side" scaling by disabling this option, provided you have a Nvidia Offload Card installed and enabled. For more details, visit FAQs page.


The changes would take effect after the system reboot.
