- Added GPI triggered functions for 4K Production Monitors. Each GPI input may now be configured as if it were a function button. Grounding the line triggers the corresponding function. The GPI functions can be configured through the function button menu, accessible through the monitor settings page (Monitor Settings > User Buttons > GPI Pins Improvements and Alterations:
- Added Rec2020 as a gamut option for SDR Color Pipes
- DCI-P3 gamut is no longer removed from the Color Pipe when calibrated to Rec709
- Reduce SDI locking times to Known Issues in Release 5.3.0:
- HDR mode and Max Bright mode can be enabled together - Work around: Disable Max Bright mode before switching to an input configured for HDR
- Sending an invalid SDI signals to the monitor may cause other valid SDI inputs to flicker - Work around 1: If using two or fewer SDI signals, do not place them on adjacent inputs
- Work around 2: Unplug any SDI cables not being used to transmit video
- Image Capture may not work as expected on PQ Color Pipes - The raw input data is captured using image capture. The overlaid image is NOT subject to the Color Pipe, it’s assumed that all images being overlaid are already in the same color space as the calibration target
