so now i want buy 3 monitors that capable to do this...
my friend told me that LGIPS is good for gaming...so i thought why not to buy it...

so LGIPS235V has 1DV1 1D-SUB 1 HDMI

now here is the question:
what cables do i need to buy for those three monitors...?
i already know that i could connect my 2 monitors to the 2 DVI port
but the last monitor what do i need....?

so i thought about it, maybe have a (from the graphics card)mini dsp to hdmi, then hdmi to hdmi( to the monitor)
i dont know if this ok?
