I have be use this adapter for about a week now and it be work , but it chew up most of my 4gb of RAM . I be go to upgrade to 8gb to see if that fix the lagging problem I be experience right now . unfortunately , I be use it for a trading set up off my laptop and I literally can not afford to have any lag time or slowness . my trading platform keep bang up against max memory available . I 'll update after I upgrade RAM to see if performance improve . if you have a more static need for a additional monitor , I would say this would not be a problem , but for a trader , this cost effective solution could be a very costly one indeed .
