Using the HDMI splitter, its going to exactly mirror the three monitors together, so you will just see four monitors with the same image. You need to plug each monitor directly into your Graphics Card.
even if i use this feature? http://s21.postimg.org/kne2ubfja/kurts.jpg
it works when i plug the hdmi cable from my laptop into my tv i can just drag it over to the next screen when using this feature, also my graphics card is a HD graphics 4000
