About 4K on Pearl-2

Pearl-2 supports resolutions from low-res SD to 4K, which means that you can use Pearl-2 to capture both DCI 4K and 4K UHD digital signals. You need the 4K feature add-on to access this feature, see Add-ons overview.

DCI 4K and 4K UHD are just different definitions of a 4K resolution. 4K UHD (3840×2160) is the standard 4K resolution available on televisions and other common display screens. The 4K resolution of 4096×2160 is referred to as Digital Cinema Initiatives (DCI) 4K, and is the resolution used almost exclusively for cinema-scale film production. It is rare to find this resolution outside of a cinematic context. Pearl-2 is capable of supporting input and output at either definition with the Feature add-ons.
