SyncMaster S23B300 stop working after 10.10.3 update

Hi All,

I have a secondary display (Samsung SyncMaster S23B300) connected by thunderbolt to my Macbook AIr, it was working perfect in terms of resolution (1920x1080) before the 10.10.3.

After this last release, doesn't get the resolution working again. If "default for display" is selected, i got 800x600. If "scaled" is selected, the Monitor native resolution does not appear in the list 😟.

Thanks in advance 🙂
