DVI vs. DisplayPort

hey guys,
so about to purchase for a monitor for my gaming rig. got a gtx 680 running alongside a 2700k at 4.5ghz.
now what i want to do is primarily play games, in 3D. i love the idea of 3D.

so i know that for the best picture quality and satisfaction i should get a monitor that supports 3D, has a 2ms response time, and a 120hz refresh rate. now from what i understand to utilise the 120hz and the 2ms you need to run the connection through DVI.
but then what is displayport for?

The Samsung s23a750D monitor has all of those features however it has no DVI port, therefore forcing me to use DisplayPort if i was to buy it. is that a bad thing? this monitor is cheaper than the safer alternative that has DVI, Displayport and even VGA (god forbid)

To get those settings in a monitor the video card has to have a dual link dvi , which most do and the display port comes in handy when you are doing multile monitors. The display port will support 120mhz refresh rate on the monitor and it is actualy going to be replacing the dvi connactions as it is intended to give more high performance features than any other digital interface.

I'd look for a monitor with HDMI. Display Port seems to be heading to a dead-end, I don't see many devices with it at all, almost all have DVI and/or HDMI, even new monitors and TVs. A monitor with dual-link DVI and HDMI will be better I think. Display Port is basically HDMI without the audio part, which when hardware vendors pick what interface to use is like having two McDonalds meals, both have the same calories, fat, cost, but one has fries while the other doesn't, which one would most people pick? Plus almost everyone has heard of HDMI, while you say Display Port and most people have no clue what that is.

I think DP ports will slowly die out.

Not to be so blatant, but you're wrong. Display Port is newer than HDMI and is not heading for a dead-end. It was designed to go specifically between graphics cards and monitors. The standard was set by VESA and principally designed by Intel. It will replace DVI when the time comes. It hasn't happened yet because analog monitors are still floating around and as such is giving DVI a reason to stick around.

Some of the advanatges. In spec 1.2, it transfers more than 17 GB/s which is consideribly more than HDMI (around 10 GB/s). The standard specifies maximum cable length, HDMI does not so if you are running longer cables Display Port is the way to go.

It can carry considerbly more than just video and AUDIO. You can support multiple monitors on one cable. By daisy chaining them together, with spec 1.2 you can run FOUR monitors at 1920 x 1200 on ONE cable!

It can run direct drive monitors, more of a laptop issue. And some smaller nit picking things are that it is royalty free and it has an actual cable retention system.

HDMI is good for your TV but for computer monitors, go with DP! Its just a technically more accomplished, capable, and a more flexible standard for manufacturers to develop with.

you wouldn't want those samsungs then... What you need is an 'nvidia 3d vision' compatible monitor.
One of these listed on the nvidia website:
http://www.nvidia.com/object/3d-vision-displays.html

and if i recall correctly, AMD uses dp for their AMD hd3d system and nvidia uses dual-link dvi in their 3d vision system... (Though amd has limited support via hdmi as well but hdmi doesnt have enough bandwidht for proper 1080p@120Hz 3D, so they use 720p) Both should be able to run 120Hz via either connection however, it's just the 3d part that differs...

edit DP is superior to dvi/hdmi and will likely replace them as the preferred connection type used in monitors. it will take some time though...
edit2 dvi-d lacks the analog part of the dvi-i, so you cant use simple dvi-vga adapters on dvi-d output

so the samsungs are not a good idea? dang i had worked that out in my price range.
so basically it doesnt matter. i'm just going to make sure i buy a monitor that is ''Nvidia 3D vision ready" and from what i see all the formidable ones worth looking at have DVI and DisplayPort anyway.

thanks fellas!

Basically if you have Nvidia and want 3D vision, go for Nvidia 3D vision 2 ready monitors. They will all be DL-DVI. If you are going AMD, then the Displayport options will be best as HD3D does not work with DVI.
