Club 3D CAC-1010-A DisplayPort to DVI Dual-Link DVI-D Active Adapter for Your Monitor/Display - USB A Powered – 2560x1600 Resolution NO HDCP Support, This is Adapter is for Apple Cinema Monitors.

This is the only adapter that makes My Apple 30” Cinema Display work at its full 2560x1600 resolution via my NVidia RTX3090 display port output on windows 11.I’ve tried various others including the star tech USB-C adapter (which does work for my MacBook Pro but not windows over thunderbolt/USBC) and this was the only one that worked properly on windows and the nVidia card.
