Windows 10: GTX 780, how do I get 144hz out of HDMI or DP?

I have dual GTX 780s and will be soon upgrading to quad GTX 780s in a 4 way sli configuration. For a while I was running 2 monitors, but as a look developer, screen space, colors, frame rates, and signal frequency are very important to an almost religious level so I bought 3 new monitors running at 144hz with a true color calibrator and sRGB config.

Problem...... Each 780 only has 2 DVI ports so I am plugging my third monitor into the second card, but that prohibits me from running sli in max performance mode. When I try using HDMI or Display Port cables to connect them all to the first card, I no longer can set the frequency to 144hz. In fact, it caps me at 60hz. I have considered trying to overclock the monitor but I feel its cable related. My HDMI and DP cables are not suited (as far as I am aware) for 4k or high frame rates. After doing some research, some people have said the cable is rather irreverent, but where I looked, that problem was never solved.

I hope someone might be able to help me figure out a way to solve this, could an active display port adapter to DVI-D perhaps fix this? is there an easier way? is it just the cables? I hope someone can help because I really want to free up this second, and soon third and fourth graphics cards so I can continue working without my render engines crashing every 5 seconds.

(side note, my HDMI and DP cables are about 6 years old, could that be part of the problem?)

Windows Update automatically install EVGA GTX 780 drivers.

Original title: Black screen on startup

I installed an EVGA GTX 780 SC today. Since doing that I've had nothing but problems. I get a black screen on startup unless I plug my monitor into my motherboard and change the GPU setting in the BIOS to iGPU. When I installed my 780 I installed the latest
driver from Nvidia's website. The **** **** Windows Update then appeared to install it's own 780 drivers on top of the ones I already installed. I also uninstalled the Intel HD 4000 driver that I was using and when I did that Windows Update reinstalled them.
So, I don't think my computer is utilizing my 780 and I don't know how to fix this extremely annoying problem.

 

Faulty Hardware corrupted page issue in Windows 10 Asus

I'm getting this too, and I'm NOT on a Laptop. ASUS Maximus VIII Hero Motherboard, ASUS GTX 780 video card. Seems ASUS all round

 

If I remember correctly, DP and HDMI will not give you 144hz capability, and an adapter wont work either. Others may correct as I'm going off memory.

Your CPU has built in graphics, you could use the DVI-D to run the third monitor @144hz and still run the SLI in max perf mode

 

What's a "look developer"?

The specs on the GTX 780 are:

GeForce GTX 780 | Specifications | GeForce

At UHD (3840 X 2160), HDMI and DP are listed at 30 and 60 HZ respectively. Nothing is said about lower resolutions. You don't say what resolutions you are using, but you may be trying to get something out of the cards which they are not designed to permit.

I haven't played with SLI for a while, and never with multiple monitors, but I believe that SLI is limited to two monitors.

NVIDIA SLI Multi-Monitor | NVIDIA

I'd be pleased to hear that I'm misinterpreting this, but I think that you can't get 145 Hz on 3 monitors using an SLI setup. Whether AMD Crossfire would be better, I have no idea.

 

Look developers design and make textures, materials, then we render, and post-process CGI scenes in movies, ads, and things of that nature.

I am using 1080p.

ATI is a big nono for look developers. Their OpenGL, and CL drivers are far less stable and there is the issue of CUDA being an NVidia Framework which is now an industry standard for GPU rendering.

 

Thank you for the suggestion. Would that give me any kind of performance hit on that monitor? im still kindof curious how that would work? I mean, if I ran 3D mark half way between the 2 screens would it be lagging on the monitor using onboard and going hard on the SLI side?

 

DP has to be version 1.2 in order to get high refresh rates. Standard DVI wont do them. You'd need dual-link DVI at best. Rather than waste money on 4 out-dated graphics card, why not get one 980ti and modernise?

Just this week I got a new Acer monitor which can do 165Hz. I had to tune it using the OD menu so make sure its enabled that way too.

 

because they are not outdated to look developers

nvidia, in the 900 series, reduced the number of OGL and CUDA cores. The 900 series is widely renowned as a joke to look developers. It doesnt matter if your 900 series is more powerful, if it has fewer cuda cores for the render engine to utilize. Besides, I already have 2/4. It would cost more to sell the 2 I have and buy 2 new 980tis than to just buy 4 780s which walks all over the 900 series when it comes to rendering.

The way I understand it is, thee 780 does have dp1.2. so, could a simple cable change possibly fix this?

Look developing is nothing like gaming. There are hundreds of hours of work that go into a few seconds of footage vs gaming where you get ok looking footage instantly. Games can use Direct X, so it really doesnt matter how many cuda cores there are. The only time you use Direct X for rendering is in what is called architectural ray tracing. It means glass will be treated as glass by each normal, not by the mesh depth samples. So a thick window will render as 2 thin glass planes, instead of one thick one. It also uses a lot of techniques to fake shading and coloring and often uses liniar grading instead of quadratic, all to reduce render times. DX12 has come a long way and might have resolved some of these issues but its still nowhere near the industry standard render quality.

 

What type of cable are you currently using?

 

The kind that I find at the bottom of a box in my server room after 6 years.... haha

 

lol then its rather doubtful that it'l support 144Hz. You'll need to buy a Displayport 1.2 cable. Dual-Link HDMI cables can also do 144. Don't confuse it with the normal DVI.

 

My other 2 monitors are running the 144hz on the dual link dvi cables now. Ill invest in a Display Port 1.2 cable and see if that makes a difference. Its sad that Tiger Direct shut down near me. I cant exactly just run out and get one anymore.

 

As far as I know, there is no such thing as a "DisplayPort 1.2" cable. I think you'll be disappointed with what a new cable does for you.

Yeah, it's too bad that nVidia has forked their products so that the consumer cards aren't great for some forms of GPU computing. Perhaps a nice Quadro M6000? (Workstation equivalent of a Titan X, apparently. Merely $5k US.)

I'm a bit surprised that you can get the monitors operating at different refresh rates at the same time, but , as I said, I'm not into multiple monitors. (Single UHD monitor for me, at 60 Hz using a DP cable.)

 

I'm actually considering an Nvidia Tesla. Actually, to be specific, two or three of them. I don't know if you know about them. They're dedicated Computing cards. They don't have any video outputs on them. Their sole purpose is to run Cuda ocl, and ogl drivers. Someecards go all the way up to 24 gigabytes of ddr5 RAM they have some for 6 and 12 gigabytes of RAM, as well, and quite few more Cuda cores than most other devices, including the workstation series.

It's important to remember, though, many rendering applications treat multiple GPUs like a distributed server cluster. Each card will handle a certain portion of the render samples. One really powerful card, in some engines, will go slower than 2 or 3 cards, each one often times being less than an 8th of the price of a Titan or ws series.

The Teslas will likely rather be an addition to my render farm.

Out of curiosity. Should DisplayPort allow 120 hertz?, in theory, and also, having only tried it for a few seconds, I wasn't really paying a whole lot of attention, but does DisplayPort have the same color Vibrance change the HDMI has? I often find the HDMI has much more saturation than the DVI ports. True color calibration only helps if all 3 are the same, or close to it.
