Question about Delock HDMI – Micro HDMI

That depends on the tablet - HDMI outputs on tablets are usually outputs only, so that will hardly work. However, many Android tablets can be used as second monitors via USB and with the help of the SuperDisplay software (costs a little). With iPads, this only works from other Apple devices. So the adapter is probably NOT the solution, but there may be possibilities. Windows to Windows - someone else would have to explain that.
