With our MacBook Pro connected to an LG OLED TV via an UltraStudio 4K Mini and grading in DaVinci Resolve Studio 17.4 with data levels set to full, the picture in the Resolve viewer is flat, as though it’s operating at video levels, making it impossible to grade with the laptop. The shots below give an indication of what we’re seeing on the MacBook miniLED display vs. the picture on our LG 55CX.
On the other hand, if we change the reference display mode from HDR Video P3 – ST 2084 to HDTV Video BT.709 – BT.1886, the picture in the viewer looks nearly identical to that of the TV. How is that even possible? Unfortunately, it’s just coincidence: it’s still not possible to grade using the Mac’s built-in display!
