Tips

To get the most out of the UltraStudio Mini Monitor 12G, pair it with a calibrated SDI or HDMI monitor that supports the same color gamut and HDR standard you are mastering for. Since it is bus-powered, ensure your Thunderbolt 3 port provides sufficient power; if you are using a hub, connect directly to the computer for reliable performance. For HDR workflows, enable HDR metadata output in the Desktop Video Utility and set your monitor to the corresponding HDR mode.
