Blackmagic Decklink FCS Display Errors
Color:
- “Unable to initialize OpenGL. Make sure Video Desktop is disabled.”
FCP:
- “• Pour le bon fonctionnement de Final Cut Pro, il est recommandé que votre système soit doté de 64 Mo de mémoire VRAM ; hors, il n’en dispose que de 0 Mo.”
- “• Final Cut Pro recommends that your system have 64 MB of VRAM; this system has only 0 MB of VRAM.”
- Quartz Extreme errors
Basically those errors mean that FCS is trying to use the Decklink Video Desktop as a regular display.
Solution: For best results, you shouldn’t use the Decklink as an extended desktop. Switch in Systeme Preferences / Decklink the “When not playing video, send :” preference to “Black” or “Last Played Frame” :

If you _really_ need the Decklink Extended desktop, make sure that :
- The primary display is connected to the first DVI output
- Video mirroring is deactivated in System Preferences / Monitors
