I Don't use the second connection because it never worked for me, I use Displayport right from the macbook air.

Hi itadmincrbc,

Unfortunately you have discovered a bug in the 2.3 beta (!).

The new logging is not enabled when upgrading from an older driver. This means that your logs don't contain the critical information about the resume from sleep. The rest of the logs does not contain much of interest.

To enable the new logging you'll have to uninstall the 2.3 beta using the uninstaller and then install it again.
Then collect the logs again.

Apologies about this, we'll fix the issue in the next release.

Best regards,
Carlo
