The best thing to do is to show you so I'll video while I demonstrate the areas I have problems with.
https://vimeo.com/642625782/ea9d88fbaeActually colour matching works on the Win 11 PC but doesn't on the Win 10 PC so that may be installation. Worst problem is play back. Slow as in like slow motion in either colour tab or edit tab with the Decklink Mini Monitor 4k shaking like mad as it presumably tries to play left and right at the same time.
PC Spec for the one I used for the video
Windows 11 - same issue on Win 10 machine lower spec.
RAM 128GB 3200
Graphics Quadro RTX 8000 - RAM 64GB
CPU i9 10980XE 18 Core
OS is on an M2 disk
All other storage SSD.
Thank you for listening.
