RE: S2716DG, EVGA 680 GTX, Unable to select 144Hz, only 120Hz?

Jump to solution

HDMI doesn't support a refresh rate above 60Hz.
No single card, not even a Titan, can play in surround 1080p,
144Hz, without turning details wayy down, so they don't bother trying this. This kind of  monitor setup requires 2 two cards minimum which is why all mac pro's nowhave dual AMD cards and 12 gigs of Vram. You have to use thunderbolt or DVI or DISPLAYPORT.
Also, I hope you plan on playing some really old games
if you want 144 Hz at, I assume, 5760x1080 with a single 680 across 3 monitors.

The 680 is not listed as a single 4k card.  I would check with nvidia on their site to see if there is a specific required driver.

A GeForce GTX 680 GPU must be paired with another GeForce GTX 680 GPU (graphics card manufacturer can be different). SLI requires sufficient system cooling and a compatible power supply.

 - 3840x2160 at 30Hz or 4096x2160 at 24Hz supported over HDMI. 4096x2160 (including 3840x2160) at 60Hz supported over Displayport. Support for 4k tiled MST displays requires 326.19 driver or later.

Thanks for the offer Chris but I highly doubt it's the monitor at this point.

I've met varying answers, as one user suggest you can achieve 144hz with dual link DVI, whereas others state the 680 GTX doesn't support 144hz even with displayport.

It seems that the issue at hand is the pixel clock speed not being sufficient to push the 144hz.

If I might make a suggestion, having some kind of information on the product page to notify potential buyers that there are requirements to get 144hz would be nice as even some newer cards would likely be unable to support it.

The plot thickens.

How were you connected with the 670 to your old computer?

Perhaps it has to do with the display port then vs dual dvi (if that's what you used).

I'll be trying a different display port cable on the off chance it's the cable (which would be surprising).

I too am only achieving 120hz.  Using Gigabyte GTX 770 4 gig with display port.  Latest Nvidia drivers G-Sync enabled.

Ya I think I've seen this issue enough (not just here on this thread) that we need an answer from Dell.

I'm out of town so can't test it with a different display port cable - has anyone tried it with one that didn't come in the box?

Dell friends - anything definitive from your end yet? I think we can rule out it being this many defective monitors (I hope at least).

Just got mine today, same 1440P@120hz max setting over display port issue.

PC is running a GTX 770 (2GB.)


Tried everything I can think of, even creating a custom 144hz resolution setting, it will immediately revert to 120hz

I really liked the monitor but mine seemed to just die out of no where a couple days ago (it literally would not turn on no matter what).

I decided to return it and not request an exchange, it was too much hassle given the price tag and the fact that this issue (not being able to achieve 144hz) has no answer from Dell.

Maybe in the future I'll consider getting it again at a good price but for now I'm going to stay away.

^ Sorry your monitor broke.

FWIW, I just upgraded from a GTX 770 to a 980. 

144hz mode now works where my 770 would only do 120hz. 

Pretty sure the problem is that the 680/770 cards just don't support 1440p @ 144hz over displayport for whatever reason.
