Driver SUpport for true 120Hz? Driver support for DisplayPort 120Hz
Hello all,

Im new so I apologise for any mistakes I may make. I had a quick question I am looking at buying the SAMSUNG S27A950D which says it is capable of true 120Hz refresh rate through a DisplayPort it has. Now I have a Nvidia 570 which has a DisplayPort so if I connect the two via DisplayPort can I assume I will be able to select 1920 X 1080 with 120Hz as the refresh rate? Now I am not trying to get 3D or anything going I could careless about that, but I am tired of 60Hz as the standard, makes me miss CRT's, and if it really does diplay at 120Hz I would love it, so can it?

I have this monitor and it will do 120hz 1080p with DVI-I and with DisplayPort. The difference is noticeable and makes a difference in gaming and even in general use like dragging windows around the screen. It's like REAL-TIME movement on your screen. Excellent response time. The only downside of that monitor is the $700 price tag. But nonetheless I am extremely happy with my purchase, I have owned it for a week, and I have JUST received my evga gtx 680 sli cards . Perfect match IMO. :)

Its nice to have a 27" monitor that runs at 120hz... I have several. I also have the Alienware AW2310, and its on sale right till April 4th for $369 with coupon code K2DKZGW4HBB00F

Im a bit worried that that Alienware monitor does not have a DisplayPort though, and I have heard to get the best response from a 120Hz monitor you really need a DisplayPort, not a DVI connection.

Not sure where you heard that but it really sounds like BS to me. Most of the current 3D monitors have a dual-link DVI connector and not a DisplayPort and they work perfectly fine.

Edit: DisplayPort would have an advantage over Dial-link DVI if the resolution of the 120Hz monitor was higher than 1920 x 1080. I believe the DisplayPort connection would be fast enough to drive a 2560 x 1600 at 120Hz whereas a Dual-link DVI would not be. I do not think you can find any such monitors currently, though.

Yeah, that info is wrong. At first I thought I would need a displayPort cable to get the best out of my monitor but that has been proven to be false. I am using the DVI-I cable that came with the monitor and I get perfect 120hz signal. Instantly noticed the difference on games, and general pc use ( ie: window dragging).

Ive heard that if you use a Dual-Link DVI that your actually just getting two 60Hz signals which is fine for 3D as your looking for two seperate signals, but if you want full 120Hz on one signal for normal non-3D stuff then you need DisplayPort as its the only thing that supports the massive rates that are needed for it. I have heard theres another version of HDMI that will support it but nothing really has it yet.

hmm idk man, i get full 120hz with dual link dvi right now in 2D. As I said, immediate difference in gaming . If I set Vsync( which I don't as its not needed @120hz) The fps lock at 120, hence 120hz refresh rate over dvi-i. I would try displayport at some point, but as of now, I see no reason to switch.

Yea, definitely then you have been given wrong information. I use my ASUS 120Hz 3D monitor every day at 120Hz in 2D mode and it works great. I use the supplied dual-link DVI cable.

It sounds like whoever gave you this information is misunderstanding what dual-link DVI is. For 120Hz, either dual-link DVI or DisplayPort will be absolutely fine, and there is no tangible advantage of one or the other.

As someone else mentioned, DP may have an advantage when 120Hz becomes available at higher resolutions, but this definitely isn't happening any time soon.

3D TVs do often operate by taking a 60Hz input (HDMI) and turning it into 120Hz, and this is not true 120Hz.
