hi there, i just bought this monitor and since i just used crt in my life well...it looks great.

up to now i'm using an old hd 3870, waiting few days for a gtx 670 to come

now the problem is that i can't use 120hz or 144hz. I plugged the monitor with the D-sub cable. It that the prob? I mean, do i have to plug it with HDMI or DVI-D to get 120/144 hz?

(when i right click on the desktop, the monitor is recognize as beq2411t ANALOG , what that means? )

any help is very wellcome
