I bought the adapter a couple of months ago and it’s been working like a charm ever since but suddenly for some reason it stopped working properly. The screen rendering has gotten so slow that it lags when I type anything. Browsing is a nightmare (on all browsers) and obviously playing any videos is not even an option with that kind of rendering speed (it used to work just fine).
The only thing that I did which started all of this is that I installed a windows update that led to a computer restart. From there, the adapter became insanely slow when it renders anything on the screen.
