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

Jump to solution

I just received my new S2716DG and was excited to get things running.

I connected it with the included display port cable and updated my nvidia drivers to the most recent version.

When I go into both Windows & Nvidia control panel, I'm able to only select 120 HZ as my max refresh rate. I've gone through all lower resolutions (I'm at the highest) and no opportunity is given to select 144hz.

For context I'm using an EVGA 680 GTX.

Is this a known issue? Is it a driver issue? Is there a solution?

Someone suggested create a custom resolution and setting the refresh rate to 144hz - would this be a temp. fix?

nVidia support ticket answer for this some time ago... hope that helps

"I've discussed this issue with development and after some research on the specification this is expected due to HW limitation. The 2560x1440@144Hz resolution would require a pixel clock of 586Mhz. The GeForce GTX 770 max pixel clock is 540Mhz. You'll need a GTX 980 class GPU, which has a higher pixel clock, in order to support the 2560x1440@144hz resolution. Let me know if you have any further questions."

Based on the S2716DG User's Guide pages 6, 11, 12, we know that the S2716DG DisplayPort in is capable of 144Hz. So the culprit is either the Nvidia driver or the video card itself. The only test you could try is using another computer or another video card in that system to see if the results differ.

Hey Chris -

Is there a list of video cards that were tested by Dell to support the 144hz feature?

There wasn't any mention of this on the product page, and given that my card is still relatively strong, it would be unfortunate if the only way to achieve 144 hz is to upgrade my still sufficient card.

I have not seen such a list. The EVGA 680 GTX came out 3 years ago. What specific EVGA 680 GTX model is it? They have 4 or 5 different ones. Look for a model number on the box.

I am not seeing an Nvidia or EVGA document that details what Hz settings the GTX 680 can do. I found this, but not any Hz data. I think we need to move this conversation to the Desktop Video board to get more eyes on it. As a test, lower the windows desktop resolution one notch. Then check the Hz maximum.

I am surprised that none of our Desktop users have chimed in. I am not convinced that the monitor is at fault. But you may initiate a monitor exchange. Test the replacement before sending any monitor back to Dell. If the replacement does not have the issue, keep it and send us the original. If the replacement has the SAME issue, the monitors were not at fault. Send the replacement back to Dell. Look to the video card as the culprit.

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'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).

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.

I've had the same experience, no option to select 144 hz, trying a custom resolution tests fine, but the option never gets added to actually allow it. Also the CRU may not be recognized by games in full screen mode.

I have a EVGA 660ti.  The product page claims to support 240 hz so we'll see. I'm going to try a few different cables, perhaps the cable they sent me ***, although it appeared to be manufactured well.

Hmm this is strange. I've been through one PG278Q which did not have this issue with my gtx 670 even though its the same panel, i've also had the PG279Q which had the same issue as this one, no go with 144hz, stuck at 120hz.

What gives? is it some form of security feature? I'd love to be able to use 144hz with my gtx 670 gpu as it is a bad time to buy a new gpu.

Yeah I'm at a loss.   I tried different displayport cables without any luck. I contacted EVGA, who said my video card absolutely supports 144 hz over DisplayPort, and recommended I contact Dell, so I did. Unfortunately this ended up in a dark black hole. Dell struggled to get me with the right support group, even had trouble with simply transferring me. After expressing frustration, a Dell Support engineer who was given the call incorrectly said he'd try to assist even though his department does not typically deal with consumer line options. He basically said he thought it should work and needs to get me over to the 'right' department. I was moved around 5-6 times, and finally I reached someone who said they 'could' help. Unfortunately, I didn't receive any assistance. The Dell client rep was not knowledgeable, and didn't even know this model could support 144 hz. I ended up walking her through how to do the troubleshooting (which I had already done). She escalated up to her boss, whom also needed assistance.They originally stated that the monitor did not support 144 HZ , which was obviously incorrect. After 4+ escalations, I was told my video card does not support  144hz, although the manufacturer of the card said that it does. I spent a good 6-8 hours wasting my time and waiting to hear the wrong answer, which was extremely frustrating.

@thevoodoo  This sort of makes sense, and I read this elsewhere. However, at 1920x1080@144hz, it should work, and I'm guessing it doesn't for you (it didn't for me). In fact, no matter how low I put the resolution I could not not get the 144hz to display, unless it's just some sort of hardcoded limit no matter what resolution.

Hi Speedstep,

Again this "makes sense", butl leaves a pretty big question: Running the monitor at 1920x1080@144 hz should work based on the above, correct?  Pixel clock at that should be in the mid 300s, which a 770 clearly beats.or even a lower resolution. Why doesn't it?

Exactly! IF the pixel clock was the deciding factor in this, lowering the resolution should work. I do not buy, for a second, that a 980 is required to achieve 1440 144hz. Numerous people who have below a 980 are able to do it. So what gives???

No it doesn't! Seems like the monitor is scaling up any signal to native resolution no matter if it's 800x600, 1024x768, 1920x1080 or anything else.

So if your GPU can't handle 2560x1440 @ 144Hz it is not possible to run this monitor with 144Hz, no matter what resolution. Here's the proof: http://imgur.com/Mq9Ioyx
