How to Troubleshoot VRR Flickering and Check Firmware Updates for the AC-FRESCO-4X
The AC-FRESCO-4X (Fresco 8K 48 Gbps 2x2 Video Wall Processor) is a powerful tool for creating synchronized video walls. However, users may encounter issues such as VRR (Variable Refresh Rate) flickering or need to verify firmware versions for optimal performance. This guide provides solutions for these scenarios.
Troubleshooting VRR Flickering on a 2x2 Video Wall
VRR flickering occurs because the AC-FRESCO-4X supports VRR by re-clocking rather than passing it through. This means the processor locks the variable frame rate from the source to a fixed output to ensure synchronization across all panels. As the source frame rate changes, the processor re-locks, which can cause brightness pulsing or flickering on some displays.
Steps to Fix VRR Flickering:
Disable VRR at the Source Device: - For example, on an Xbox, navigate to
Settings > General > TV & display options > Video modesand uncheck "Allow Variable Refresh Rate."Set a Fixed Resolution and Refresh Rate: - Choose a stable configuration, such as 4K at 60 Hz, to ensure consistent output across all panels.
Power Cycle the Devices: - Restart both the source device and the AC-FRESCO-4X to renegotiate EDID (Extended Display Identification Data).
Following these steps will stabilize the image across all panels and eliminate flickering.
