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 Offloading can only be supported only when Direct Sync is enabled.

• Enable 60 fps: Enable this feature for better content synchronization.

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.
