The installation of WiDi on the computer was not a cakewalk, the software refusing to settle early (forced to unpack the Intel graphics drivers to force installation, obliged to update the AMD drivers also (stability problem otherwise), etc).
The device itself is simple to install: one branch, pressing the switch (which is very discreet) and connects via WiDi software (be careful to configure the firewall).
Good surprise, the image responds in near real time (while I know WiDi TV with a latency of the order of a second) time in hand we observe in times of micro jerks.
I use it mainly to play videos via xbmc, it works without problems (be careful to configure the synchronization refresh options for optimal results).
