Workstation Frying all my Monitors

Hey everyone,
I have pretty major problem I'm hoping someone may have an answer to. I bought a really expensive pre-built for work last year. I'm an animator and wanted something to last me a while. But ever since I got it I've been having the problem of monitors producing strong burning odors, but only when attached to that specific computer. More details below. Also, I apologize if I've posted this in the wrong thread section. I'm not really sure what the probably is yet so any tips on where to post it to get the best help on the matter would be much appreciated

Hardware
Asus X99 Deluxe II
Intel Core i7 6850K
8x Crucial DDR4-2400 32GB ECC Reg.
EVGA GeForce GTX 1070 8GB
Onboard Sound
3 x 1TB SSD
1 x 6 TB HDD

Short Story
My workstation computer fries any monitor I plug into it. The symptoms of the monitors start with a slight electronic burning odor, then become stronger and stronger, some monitors end up having their power supplies start emitting strong smell as well, which I've replaced with no results. The smell eventually becomes so strong that I have to unplug everything and leave the room for days. I've developed an aggressive cough and chest tightness because of being exposed to it.

I've tried four monitors on the workstation, all produce a smell. I've had the GPU replaced twice, the PSU replaced once, had two new 20A circuits installed in my home along with purchasing an Automatic Voltage Regulator to insure the problem isn't on my side, and have tested the same monitors on many computers and gaming consoles without getting the any burning smell whatsoever. Computer has been hastly looked at by company who made it and they say nothing is wrong. I'm extremely confident the workstation computer is causing this, I just don't know how.

If anyone could provide some thoughts on what they think is going, I would be in your debt.
Thanks.

Long Story
Upon receiving it from the company I immediately had an issue with the GPU acting funny, glitching of the screen. The company sent out a replacement graphics card to replace it. I didn't really notice any else until about two months later when I began to smell a burning electronic odor that was very unnoticeable. I checked everything out, found nothing, then went along my way. Over the next couple months this process repeated as I kept looking for a smell that was getting stronger and stronger. I finally narrowed it down to my monitors. I was running two 27" LG monitors and 27" Cintiq monitor. The strong odor was emitting from the backs of every one of the monitors and the power bricks of the LG monitors themselves were emitting an even worse smell.

So I had enough, I though something like a power surge had come through a took out my monitors, as no smell was coming from my new workstation. I shut down everything, sent the Cintiq for repairs, put the LG monitors aside and got new monitor to use while I figured out what happened to the others. After about a week, the smell came back.

Now I knew something was up so I called up the company who made the workstation again. This time they sent out another GPU and a replacement PSU. I had to wait on those parts so I stuck the new workstation aside and began working with my backup system. I called an electrician also to make sure there wasn't something grounding out and causing my equipment to fry. He checked the voltage coming into the house, good. Voltage coming out of the office outlets, good. Everything seemed to be fine. He made a suggestion that perhaps with the 3 monitors and the high-end workstation running on one circuit, it may have theoretically drawn more power than it was supposed to, without tripping the breaker. He recommended running two new 20A circuits to my office, both going into one specialized outlet. So a large chunk of money later, I had an outlet in my office that contained two 20A circuits, each with their own breaker switch.

So once that was installed I started using my backup system with my new single monitor, which now wasn't emitting any smell anymore! YES!! I was so exciting, I thought I figured it out and the problem was solved. I used it for weeks as I waited to get my Cintiq back and the replacement parts for my workstation. During the time I smelled nothing and thought I was in the clear.

So I got back everything and waited for a weekend to install everything. I got my Cintiq, which according to the manufacturer was in perfect working condition and had no internal defects. and was really excited to use it again, so I plugged it in to my old system and used it for a while. I was excited and confused that the smell was no longer there. I was starting to think it was perhaps the workstation. I continued testing multiple computers and even gaming consoles on the cintiq and main monitor, they produced no smell for the hours and days of runtime. I even broke out the 2 LG monitors that were producing some the most fumes, nothing. Everything monitor was acting normal.

I installed the new GPU and PSU in my workstation, started it up at the beginning of a work day, and by the time the day ended I had to leave the room because the burning smell was so strong. I tested all sorts of combinations, workloads, and configurations. Switching monitors back and forth between different computers and kept coming up with the same conclusion, my workstation was somehow making all my monitors burn somehow. Through all this I've slowly been developing some weird and strong cough and chest tightness that I believe it associated with spending all this time in an enclosed space with all the burning equipment. So I stopped using the workstation.

I sent it in to get looked at. The company ran it through a test which include attaching 3 4k monitors to it and running it for a couple hours, which I believe wasn't enough to diagnose the problem whatsoever. I'm not sure what tests they ran but in the end they said nothing was wrong and they kept referencing the 3 monitors running fine with no smell emitting. First off, I felt like them trying to replicate the problem that way is understandable but to say after a couple hours of testing that they couldn't reproduce the problem is kind of maddening. They sent it back to me saying nothing was wrong with it as well as the two previous GPUs and PSU I returned to them.

So Tuesday I plugged it in for the first time since getting it back. I worked on it for 5 hours, then started getting the same slowly intensifying smell again, and haven't used it since. I'm really at a loss here guys. I have no idea what to do. I can't stomach the smell or even breathe properly when I use this workstation so I essentially have a really heavy paper weight here until I find out what's wrong. People keep telling me that voltage and stuff can't be transmitted through display ports and stuff but I don't see any other conclusion. I called EVGA and talked to the GPU department and the guy said that if the same problem persisted through 3 individual GPUs, a PSU, and isn't present on any other system, then it sounds like the workstation has a grounding problem.

If that were true, I think the company would have caught it but I'm skeptical that they took the repair seriously and just did a quick I told ya' so test and sent it back out. I know this was a long post but wanted to include as much detail as possible. Is there anything I can do to test for other issues? Testing the display port voltage, the PCI Slot, find grounding issues, or any other problems?

Thank you in advance for any of your replies and I will try to respond to any questions or suggestions you have as soon as possible.

Thanks,
Dan

with speed of the refresh of the monitor if the monitors only 60 hrz it wont synk to any speeds faster then 60. it just give you the out of range or black no signal message. on your power cable the 13amp cable is just the wires in the cable are thicker then the older 10 amp ones. you may want to see if there a pin and power diagram for your gpu online and have a local shop that has meter and scope check the voltage and signal.

have the vendor of the pc send you another brand of gpu. on there first replacement card was the serial numbers different. sometime vendors if they find no errors will return same bad part back to you. on your gpu issue make sure you have a new video cable to rule out a miss wired or short in the cable. if the pc has onboard video port pull the gpu see if the error still there. if it is then there a power or ground issue feeding back from the mb into the monitor. if they wont swap out the pc use your states lemon laws.

Thanks Smorizio. I had no idea that was going on. I've run tests on the GPU that max it out for couple hours and had no problems temperature wise, so it doesn't seem to match the problems people are getting in that article, but I'm definitely going to check out the serial numbers to make sure.
From what I can tell on their online repair reports, the company tested the GPUs I sent back to them and found no problems, then filed an RMA. I've also been switching the types of cables I use and have the problem taking place regardless of what type of port I use on the GPU, so I've ruled that out as a suspect.
A computer repair tech said that some companies who make high end prebuilds max out the hz output on the GPUs when they send them out to make sure they are best setting by default. Do you think these symptoms would be caused by a 60hz monitor receiving 120hz? Also, I'm looking at my power supply power cord and it says 13A 125V. All the computers I've ever used only us 10A cords. Could that be and issue as well?
