And an HDMI cable which is at least compliant with specs 2.0a. Also, to use UltraStudio Monitor 3G, make sure you have a real Thunderbolt 3 cable, not just USB. * Even though this is far from optimal (I know!), and since I am just an amateur and not a pro, to grade in HDR I use my Samsung LED TV: I got a Blackmagicdesign UltraStudio Monitor 3G to connect it to my Mac, it costs ~100 bucks. mkvmerge (available via mkvtoolnix** free, may be not should be nomore necessary if DVR embeds correct HDR10 metadata, which is not always the case in my experience).MediaInfo (free, but not a strict requirement, just useful to check that the final result is ok). ![]()
