Have the unit now more than a week in service and no problems festgesetllt. Installation: Everything is done to unpack => Connect => finished. The installation (if one can speak of it at all) went without a hitch, both Eingabgeräte and monitor functioned at first attempt. Drivers and the like are not required. Quality: The device runs with me on a 19 "with 1280x1024 and 24-bit color and delivers in terms of image quality, the same result as for direct connection to the graphics card. Keyboard and mouse work as easily. Also works very well, switching in general and specifically the automatic switching at shutdown one of the two connected PCs. The integrated connection cables are indeed nich excessively long, should be sufficient but usually. Conclusion: The unit is comfortably small, makes optical ago what, gives very good results and is easy to handle. The options to switch (on the device, automatically or via keyboard) all work well. Therefore, it also receives an absolute recommendation from me.
