Hi all,
I am trying to get my MacBook to work with my Korean Crossover 27Q with no scaling.
I’ve tried the CAC-1510 and at least get a picture for 1 second before the screen goes black (backlight still on). Does anybody have any ideas where to move from here? It would suck to trash a perfectly fine monitor..

Could you mail [email protected] ? Might be an HDCP issue.

e-mailing club-3d should get you a firmware updater that will change the CAC-1510 from the HDCP-ON variant to the HDCP-OFF variant which may be necessary for macOS when using a display that doesn’t support HDCP. The EDID of the display should indicate if it supports HDCP.

You can use SwitchResX to verify if the EDID has HDCP support. Export the EDID for the display from SwitchResX, then view the EDID in a text editor. For example, My Apple 30 inch Cinema Display from 2005 has “HDCP is not supported”. Newer Cinema Displays have HDCP supported.
