Prior to using your LG OLED TV as an HDR grading monitor, you’ll probably want to calibrate it. LG recommends a burn in time of 100 hours of HDR content for the most consistent pixel response. In order to calibrate using a Mac, you’ll need VMware Fusion 12 Player, Windows 10, a colorimeter, a USB drive and Calman software. VMware Fusion Player allows you to run Windows 10 on your Mac as a virtual machine. It’s free, easy to install, and a joy to use. Here are instructions for installing VMware Fusion 12 on your Mac.

No other consumer brand approaches the level of calibration made possible by the partnership of LG and Calman.
