Display port vs DVI Dual link

[joseph9012]

Do you need display port and is it better in anyway?
I am thinking about getting BenQ XL2411Z but it doesn't have display port does this matter?

Thanks

It matters in the sense that DVI does not officially support that sort of bandwidth. If 144Hz fails to work for whatever reason, everyone will be pointing fingers at everyone else when you try to figure out why it isn't working for you but works for your neighbor who has a seemingly identical setup.

Im not understanding so DVI-D could fail but Display port has less chance of failing or doesn't fail?

DVI has been deprecated several years ago, the official specs have not been updated beyond 1920x1080p60. But DVI uses the same transceivers and video encoding scheme as HDMI, which is where DVI gets its unofficial support for higher resolutions from.

But would DVI dual link get 1080p 144hz with reliability

Yes you'll have no issue with dvi to get 144hz on that monitor. You have no other choice with that monitor anyways.

Maybe. That's the best answer you can get for something that isn't officially within the spec. It will depend on the GPU, the quality of the GPU's PCB, the quality of the cable, the quality of the LCD's PCB and the receiver chip on that PCB. Each component along the path that does not meet the HDMI 1.4 spec over DVI connectors and cables reduces your chances that it may work.

That's like giving a warning to every person buying parts that it maybe faulty. There's no point in mentioning it.

There is a rather large difference between a faulty part which fails to meet specifications and operating parts at speeds well beyond the highest speed they have been officially rated for.

But the limit you mentioned is for single link not dual. It does not go over dual link specs.
