DVI and VGA provide case no "color distortion" as often described here; Sound through the HDMI port on the Samsung screen also works wonderfully.
Incorrect insertion of the adapter is not possible because it has chamfered at the lower edge 2 corners, so it is clear how it is to be clean; whether I have done differently purely by force untested.
Even after prolonged use, the box is not warm, noise (buzz beeping) were also not found.
One star deduction, however, there for the missing awakening of the monitor from standby via VGA. Does the laptop in the power saving mode and turns off the monitors, which works just fine on all connections, only waking up over VGA is not possible. Both monitors stay in standby and wake up only after the re-infect the DisplayPort connector back on.
Conclusion ---- ----
Who does not have power-saving mode or VGA generally do not want to use is operated super with the adapter. Even with the VGA error I would buy him still and set / turn off the power-saving mode accordingly. Warning: It is always only ONE output path, ie 2-3 screens will be controlled at the same time with this adapter does not go.
