I have a z87 classified motherboard with two mini display port running intel i7 4790S chip. My problem is, I have Benq DVI-DL input. How can I get 144hz refresh rate?

I've read that you have to buy a $100 converter to get that refresh rate. If that's the case, I would just return the monitor. Someone said that a DVI-D converter would work?

You can't get refresh rates higher than the specs of the monitor. No Matter what you put inbetween.....
It would have been a lot more helpful if the model of the Monitor was posted instead of the input that it has.

Have you used the GROM software that you got with the monitor and have you set it up to change the rate during gaming?
Have you changed the refresh rate to 144MHz in the Display properties for windows?

I haven't received my monitor yet but I realized that my motherboard only have mini display port and the xl2411z monitor only have DVI-DL. I've read that a converter will not allow maximum refresh rate, but I'm getting conflicting information. So I need clarification if I can get 144hz with passive converter.

I don't want to spend another 100 dollar for a mini display port to dual dvi converter. I would have been able to buy a better monitor with the extra 100 dollars saved on the active converter.

If it doesn't work, I guess I'll consider it as a lessons learned.

You need to read through this..

Example display modes (dual link):
QXGA (2,048 × 1,536) @ 75 Hz with GTF blanking (2 × 170 MHz)
HDTV (1,920 × 1,080) @ 85 Hz with GTF blanking (2 × 126 MHz)
WUXGA (1,920 × 1,200) @ 120 Hz with CVT-RB blanking (2 x 154 MHz)
WQXGA (2,560 × 1,600) @ 60 Hz with GTF blanking (2 × 174 MHz) (30-inch or 762-millimetre Apple, Dell, Gateway, HP, NEC, Quinux, and Samsung LCDs)
WQXGA (2,560 × 1,600) @ 60 Hz with CVT-RB blanking (2 × 135 MHz) (30-inch or 762-millimetre Apple, Dell, Gateway, HP, NEC, Quinux, and Samsung LCDs)
WQXGA (2,560 × 1,600) @ 60 Hz with CVT-RB blanking (269 MHz) (This is for high end monitors when operating at greater than 24 bits per pixel.)
WQUXGA (3,840 × 2,400) @ 33 Hz with GTF blanking (2 × 159 MHz)

Here's another point
"Dual link maximum data rate is limited only by the bandwidth limits of the copper the DVI cable is constructed of and by the DVI signal's source."

And then the whole thing depends on the quality of the copper wire used.....

Here are a few cables that will give you the required refresh rates

Yea...i pretty much knows about that. The deal hear is from mini display port to dvi.

Best solution. Don't buy converter, it cost $100 or more for a not reliable converter. You can buy an nvidia 750 for that price and will have the ports you need.

I elected to buy the passive converter for a few dollars and put the money saved on a new nvidia graphics card.

It's a stupid idea to buy an mini display port to active dual dvi converter.

i bought two monitors that needs converter. I'll buy me a nice card intead of putting into converters.

Exactly, but, couldn't give you that solution since I thought you were stuck on the budget for a new card. I would never go multi monitor on an IGP, certainly prefer a GPU for multi monitor setups and excessive gaming or GPU intensive programs.

The thing is the IGP is the intel hd4600, not for gaming but it should run two monitors without any problem. The converter will cost about 200 dollars (one for each monitor). For less than that, I can get an nvidia 750ti and let that run the two monitors and be able to play games at high res (higher than xbox one and ps4 lol).

So, this is a quick reminder to those who are buying a mini-display port to dvi converter.
