Hi, I upgraded to v3 and I’ve been getting this error ever since. I’ve tried using previous versions and reinstalling dispcalgui and argyllcms…but no luck. It used to work flawlessly. Not sure what’s going on.
Ok, then you are affected by a known bug under OS X: When a Chromecast is present and detected by Argyll CMS 1.7, this messes up display enumeration in dispcalGUI. A workaround is to update to the latest beta snapshot of dispcalGUI. Here’s how (you need to be using the 0install version): Open the “0install launcher” from the disk image. Click on options. Enable the “Help test new versions” checkbox and click OK. The dispcalGUI version should switch to 184.108.40.206. Click “Download”.
