After installing the software for the Mac and reboot, every connected monitor, driven directly with the best resolution for him and is as usual configurable in System Preferences. (Scale, color, arrangement, etc.)
Application:
I ordered the adapter to two LG 29EA93-P full to driving 2560x1080 pixels, since my Macbook only has a Thunderbolt output. I have also tried the Adapter me different other monitors, which were all recognized and usable without any restriction.
The transferred image is excellent sharp and I see no response delays for directly connected screen. I can run a test basis BluRay and can detect any interference or distortion. Since I do not get in involved on my Mac, can judge this respect nothing ;-)
Conclusion:
The adapter is not very cheap, but there is after long research on the internet, no comparable device that supports the 2560er resolution on Macbook. The build quality is superb and the result is perfect for my applications.
I would recommend this adapter and would buy it again.
PS: About a positive review I would be happy =)
