I do not have that monitor.

Some things to try...
1) Change display cable (HDMI? Displayport? DVI?)
2) Have you checked the GPU? Check PCIE bus. Check power connectors.
3) Does it go black when you start windows? or just in 3d rendering applications?
4)Change port on the back of the GPU.
5) are you using Windows 8?
 
Have you checked the power plug on the monitor, making sure it's holding its power (unlikely...but plausible. Stating this factor because the monitor is infact a foreign monitor.)
Does the monitor have multiple connections?

Thanks for the responses. Stallin, I have already checked all the inputs on the card, and my HP 30 inch seems to work just fine with the card. I tried using both dvi cables as well. Today I started the computer without turning the monitor on, then when I did turn it on I got a black screen with the standby light on the monitor. I flipped on my HP monitor and then the sparta turned on and I got picture. I am running windows 7 64 bit, freshly updated. I should also note that it has done this from a brand new install with brand new hardware. Sometimes I can use it all day and then the next day I have to play around with it.
Bcavnaugh, I couldn't find any drivers or firmware for it. It didn't come with any either.
I was hoping someone had a 301 sparta around....

Yeah the buttons don't do crap. 

Its not the monitor, its the video card.  I had that monitor, worked fine on my 780 ti and worked perfectly fine on my wife's computer with a AMD 7850.  Once i bought the 980's the thing had problems all the time.  I ended up buying a new 4k monitor and the card is having problems with the display ports as well.  EVGA has a new BIOS support will give you if you email them but it doesn't fix any of the problems and they'll try to tell you to update your monitor's firmware, which is bull**** cause that's not the problem.   I would tell EVGA to refund you cause their 980 has known issues that they refuse to fix.  Just google 980 display port issues and see what comes up.

Hmm, that would make some sense. I guess I can try my wife's card and see if it does the same thing. I doubt EVGA would refund me my mony since this 980 was a step up, but maybe they would allow me step up to the new TI? 

Do you have a sparta?

maybe phobicsquirrel could consider Ben Q. They're pretty affordable, and should work with the 980's right?

Does anyone own a Yamakasi 301 Sparta with a gtx 980 and notice that randomly the monitor will just turn black? It happens out of the blue, and somtimes it won't even show a picture when booting up. I have to unplug the monitor several times or turn it off and on. It's like the driver just stops working. Mind you I haven't seen any drivers for the monitor so the driver just shows up as a generic display driver. The monitor is not overclocked or anything, it's running 2560x1600. I also have the latest drivers for my gpu but it has been going on since the 980 first came out. I should also mention that the monitor did it with a gtx 780 sc.

I dont have a EVGA card, but i have the same problem on Gbyte 970 G1.
Same monitor, Sparta 301.
 
The screen just goes black from time to time. 
Sometimes i can unplug the monitor from the power, plug it back in, and press ctrl-alt-del to come to lock screen, choose task manager and it would fix itself.
It seems that windows 8.1 lockscreen is running different res  / refresh rate from the normal desktop.
Sometimes i just have to reboot the pc.
 
Tried different dual link dvi cable, no change.
 
This is with 344.75 nvidia driver. With the latest one i can get to log in screen, but then it goes black.
I filmed it. youtube.com/watch?v=_dYfTSPrSos
 
 Everything worked fine on gtx 770, even SLI.

Almost put my monitor up for sale today after all the problems i had with the latest nvidia driver.
But then i found this post, and another one at nvidia forums with bunch of ppl having the same issues. Different monitors though.
But it seems to be card related and not monitor.
 
Edit
Updated the bios on the card yesterday in hope that "improved compatibility with some monitors" would improve the situation, but the combination of latest nvidia drivers and new bios has still the same error, monitor goes to standby right after login screen.

I just wish 144hz G-Sync was available in a 30" 2560x1600

Sounds expensive...

Yes, I have a Yamakasi 301 Sparta.  2560 x 1600 dual link dvi is the only input.
I also was using a Nixeus VUE30 also 2560 x 1600.
Both were attached to a GTX780 and worked well.
I am using windows 7 home 64 updated to currency.
The Nvidia drivers are 353.30.
 
I upgraded to a Philips 40" 4k monitor BDM4065UC, (attached via DP) which replaced the nixeus.
For whatever reason, the Sparta did not detect so to get going, I replaced the Sparta instead.
All went beautifully with a nixeus as a side monitor.
I wanted higher fps, so I replaced the GTX780 with a GTX980ti.
All again ran well, and I was getting 60fps in most of my games.
 
I had a better use for the nixeus which has speakers, so I tried the Sparta 301 instead.
On a clean boot all worked well.  But when I used windows sleep, the yamakazi would not wake and was not detected in windows; only the 4k monitor worked.
  Reboot and only 4k worked.  Crazy.
I found that if I powered off the Sparta and then did a reboot, I could get both monitors working and fully functional.
 
It seems to me that for some reason, the graphics cards are not detecting the monitor properly, or the driver is at fault by not recognizing the device info from the graphics card.
I suspect the driver because on boot, I can see the bios screen on the Sparta, and windows starts loading.  It goes blank at about the time that The driver would be initializing.

 
How does that phillips 4k do during gaming? The price seems nice and I'd like a 40 incher!
 
Update to this.... I got a msi gtx980 TI and it's still happening. I'm starting to lose my (Word deleted for Language), I'm wondering if windows 8 will cause the same issue... but I'm thinking it's more gpu based. 

Just wondering if you were able to resolve this. I'm having the same issue on the following rig:
 
Yamakasi Sparta 301 LCD S-IPS QHD 2560x1600 16:10 DVI (Dual Link) 30 inch PC Monitor
Intel Core i7-6700K 4.00GHZ 8MB Intel Smart Cache LGA1151 (Skylake)
32GB (8GBx4) DDR4/2400MHz Dual Channel Memory
ASUS Z170-PRO GAMING Motherboard
NVIDIA GeForce GTX 980 Ti 6GB GDDR5 PCIe 3.0 x16 Video Card
 
 
 

I have identical issues and have done some extensive troubleshooting, but still no luck. I will try to be as specific and succinct as possible in my troubleshooting methodology below. My hope is that someone can add to or produce some progress on this issue where I have hit a dead-end.
 
System:

• Intel i5
• ASRock Z77 Extreme4 Motherboard
• Corsair 16gb DDR3 1600 RAM
• Windows 7 Professional (x64) - SP1 + Updates
• EVGA GTX970 video card
• Yamakasi Sparta 301 monitor (native 2560x1600 resolution)
• Latest NVidia driver 361.43 (12/21/2015)

 
Symptom:
[Note: I typically use multiple monitors, but for the sake of reducing variables, I am posting from the perspective of using a single Yamakasi Sparta 301 monitor as the only connected monitor]
When booting, I can consistently see the BIOS splash screen and POST info. I can also see the Windows Loading screen. As soon as windows booting has completed but before getting to the Login screen, my Sparta 301 goes black. No display is detected at all. If I unplug the DVI cable from my GTX970 and plug into another DVI port, the monitor sometimes comes alive and works, at least until the system is rebooted, at which point it goes black at the same point. Also of important note, when using this monitor in a multi-monitor configuration (so I'm not working blindly with a single monitor), the monitor itself is not detected as being present by windows or the NVidia control panel. It's like it doesn't exist, even though I can watch the BIOS, POST, and loading screens just fine as the machine boots. 
 
Troubleshooting
GTX660 vs GTX970
I was previously running an MSI GTX660 card and had no problem whatsoever, using the same NVida driver version. I can still swap back to that card and everything works as it should. Adding my new EVGA GTX970 card produces the same "no video" problem as before.
 
EVGA vs ASUS
Thinking the problem might have been the EVGA GTX970 card, I purchased an ASUS GTX970 card, which produced the exact same problem as the EVGA card. Two different branded cards with the same result. From this, I've concluded that it's not a problem with EVGA's card, but with GTX970 (and reportedly GTX980) cards in general, but seemingly not with GTX600 or 700-series cards.
 
Windows configuration
On the assumption that Windows itself could be an important variable, I completely flattened my hard drive, re-installing Windows 7 from scratch (using original unmodified DVD media). This actually seemed to work briefly using the Microsoft default video driver. As soon as the driver was updated to the latest NVidia driver, the problem came back. It might be fair to note that other Windows updates were being installed at this time (about 185 of them), so the NVidia driver is not the only variable. However, I still conclude that the driver is most likely the culprit since my previous GTX660 works with this configuration.
 
NVidia Drivers
Since this monitor seems to be working (albiet briefly) with an old default Microsoft driver but not the newest NVidia driver, I can't help but conclude that the NVidia driver plays an important role in this monitor not being detected 
 
Yamakasi 301 Sparta Monitor
Suffice to say, that this monitor is not completely innocent either. There seems to be something about the way this monitor presents (or doesn't present) itself to video card or to Windows that produces the black screen / monitor not detected problem. This might very well be fixed with a monitor firmware update, but since Yamakasi doesn't have a website, nor any support that I can find, I can only assume that the Korean producers of this monitor are not interested in supporting it with firmware updates, forums, help, or in any way. This sucks, as it removes the element of troubleshooting the monitor itself.
 
Different Sparta 301 Monitors
My son has a very similar configuration to me, with identical video card and identical Yamakasi Sparta 301 monitor, and is experiencing the exact same results. He has a different processor (i7), and different motherboard (MSI), but the video card / monitor / driver configuration is the same. I've tried swapping monitors with him, but we both get the same black screen / non-detect problem either way. If nothing else, I can eliminate my specific Sparta 301 monitor from the equation, and can authoritatively speak to results from multiple monitors of the same type.
 
Different types / brands of Monitors
I purchased a new Acer 4K UHD display which works flawlessly with this EVGA GTX970 card. I also have a Vizio 1080p display that works consistently well. Unfortunatley I do not have access to another non-Yamakasi monitor with which to test.
 
Adapters, Converters, and Other Attempts
I have also tried using adapters and converters with no significant results: HDMI 1.4 to DVI-D Dual Link converter; DisplayPort to DVI-D Dual Link converter
 
Other Video Cards
It's also been reported by other people that they have had success with this monitor on newer ATI video cards. ATI apparently has a registry setting for their drivers that allows one to disable the DDC "feature", whereas NVidia does not appear to allow this same disabling. [For further info on this, search Google for "DMMEnableDDCPolling", which is the registry key that allows disabling DDC for ATI drivers.]. I'm not sure if/how DDC plays a role in this equation, but it was worth noting success on a different video card platform.
 
In conclusion
I would be interested in anybody's input here, but it seems to me that the only variables that can be manipulated are the NVidia driver, or possibly the GTX 900-series chipset firmware; both, working in partnership at the hardware abstraction layer, and both belonging to and responsibility of NVidia. Though I obviously don't have a solution, it seems that the ball is firmly in NVidia's court to produce a working solution. Please correct me if you think my conclusion is erroneous.

GFelts,
 
I can't fully dismiss your conclusion. The monitor definitely seems to be the biggest variable, and unfortunately an unsupported on at that. The head-scratcher in all of this is that the monitor worked (and still works) perfectly at full resolution using an earlier (MSI GTX 660) card. There obviously seems to be a toxic chemistry between the monitor and the video card.
 
But you're right that the Sparta was a relatively inexpensive monitor ($350 price range at the time), and the odds of getting either Sparta or NVidia to address the issue with this specific (and not particularly popular) monitor is very low. It's probably time to either retire or re-purpose this monitor. It's sad since I really liked the 2560x1600 resolution, the screen size, and the color reproduction. Oh well; just another example of Moore's Law in action.
