I have 3 Viewsonic V3D231 monitors and one LG monitor (16M65A – only VGA compatible). I am currently having one MiniDP to VGA converter. both these monitors are not DP compatible but both are working with this converter since I have only one converter I checked them by connecting one by one and also I checked this in all MiniDP ports in Graphics card and found it is functioning. My question is can I buy 4 of this MiniDP to VGA converter (It is cheaper in price) to drive all 4 monitors (3- Viewsonic and 1 LG)? Thank you.
