ok so i have a alienware laptop mx17r4 and also recently bought a acer 24" monitor which both products support 120hz. The laptop does not have a dvi port so i bought a mini DisplayPort to DVI (adapter).
I tried both passive and active adapters but cant seem to get 120hz on the screen. Would there be any other type of adapter that i should be using? i have searched every where and asked all of the tech shops around here and they have no idea.
i also found this recently and hoping when it arrives it will work
Mini Displayport DP TO 2X DVI I Dual Link 24 5 Converter FOR Imac AND Macbook | eBay
If someone could help and point me in the right direction it would be amazing, thanks
