I have the same issue, and have posted some of the large threads on the web about this. PM me on the blurbusters thread: https://forums.blurbusters.com/viewtopic.php?f=10&t=7358 I do not use this site very often. We have a discord group going deep into find the cause.

Simply put it sounds like you and I are not experiencing the same issue at all. Although I have some issues with LOD, Textures, Jagged shadows and the like I have much more severe and apparent issues than that which point directly to electrical being the cause. I am not saying your issues are caused by electrical, I am saying that it is possible though and you will need to explore that yourself.

Electrical problems have multiple flavors. I own an Online UPS and have tested on battery. There is still radiated interference (EMI/RFI) and that interference can couple to cables (acting as antennas). How do I know this is the case? My Online UPS (double conversion) will filter the AC mains fully by converting it twice from AC to DC and then the PSU will do this once as well (transients cannot traverse this process) however there are 2 things a UPS cannot do as far as electrical problems are concerned. It cannot solve issues of interference being radiated within your home, and it cannot solve "noisy ground" problems as the ground (protective earth) is passed through however by disconnecting the UPS you are effectively floating the ground which will rule that out. How do I know its radiated interference in my case? Because placing shielding material around my cables or even placing a pseudo Faraday cage around my monitor will make the display much smoother as well as improve my input consistency. Hope that clears things up. And like you I have a brand new panel, circuit breaker, outlets and even a brand new meter base and neutral feeder connections and yet I still have this issue because it is not local in the sense of my house. It is an infrastructure issue regarding electrical continuity of multiple homes (via water lines) and how unbalanced return current can create large electrical/magnetic fields. I have confirmed as such with a proper Gauss meter, that the levels in my home are highly elevated. Although if you do not have issues in line with what I have we could be speaking to entirely different things which I suspect many people in this thread have different problems going on. Maybe only a few in this thread share my problem but for the sake of awareness I am sharing so that folks know it is possible for an electrical issue to cause these things.

Just wanted to throw this out there. I have a similar but slightly different variation of this issue. While my display is affected in similar ways (blurry, some jaggy edges, and lots of hitching), the main symptoms of my issues are input delay, inputs dropped, de synchronized inputs etc. Also sound quality is muddied and poor. You may have seen the Nvidia topic on it and I had the exact symptoms that guy did. If you have my issues they are absolutely electrically caused. I have 100% beyond doubt confirmed that. Power conditioners, Online UPS, Shielding, Ferrite and Toroid cores/filters, and a host of other things that affect electrical flow all affect the severity of my issues. Like Meeseeks stated this problem also affects all devices: consoles, TVs, PCs, mobile phones, laptops running on battery, and interferes with Wifi and network signals in the home. My PCs and devices work absolutely fine at my friends house in another city. There is no damage to my components. I also confirmed that there is an electrical issue with the infrastructure around my residence that leads to a problematic scenario. This has to do with article 250.6 of NEC: Objectionable current on a grounding conductor. I have not solved this issue- and the only people I know that did moved locations. However I do have some leads on the cause which could potentially lead to a solution. If you want to know more PM me and I will point you in the right direction. I do not have time to argue that this is not electrically caused so if you disagree, then so be it I cannot convince you. However I have observed it all first hand, have adequate data and received professional guidance to get to the point I have. Thanks and good luck everyone.

Look man I have addressed each and every point you are asking me about. There is simply too much information here for it not to be a long story. The apartment is less than 5 minutes drive from this location. Same issues. Same weird electrical behaivor. I moved from that apartment into a house that my family owns. I am now in the house. I have more control over the setup, in the apartment I had to fight my landlord the entire way, to do anything. To be fair I have no idea if the doorbells and weird behaivor were connected. It was just another very strange observation. How did you test for polarity? I tested using a GFCI outlet 3 prong tester. I tested every outlet my PC has been plugged into, never plugging my PC into one that has shown no grounding, or reversed polarity. When my electrician came to the house he found several mis wired receptacles in the kitchen. He then replaced them. "Playing with ferrite beads is nice, but what frequencies they affect depends on the material, size and wrap." Yes and I do not know what frequencies I am dealing with. Care to explain how I can find that out? I have done a walk through the house with my AM radio and the power turned off. Nothing is out of the ordinary. Nothing was plugged back in after it worked great for a day. It is seemingly random, I have tried with no success at all to match up when they lag is most minimal with what devices, and events are happening around me. I have tried this for 1 year now. There is no rhyme or reason to it. "When I am discharging charges from my devices how should I go about that? You don't." What? You can discharge a PSU by holding down the power button with the cables unplugged. The fans will spin up and it should discharge all capacitors within a few minutes. Why even mention it if you do not know this? Wait you are honestly taking r0aches advice seriously.... The dude is clearly dealing with a similar issue. He goes on to admit that moving his keyboard cable changes his mouse tracking drastically. If you keep reading he starts accusing me (and others with this issue) of living on top of Chernobyl. He insists that I am living underneath high voltage power lines, and his source for why it is physically harmful (health wise) leads to some snake oil salesmen who wrote a very questionable paper on it. With all due respect that guy is no one I should be taking advice from. The entire site knows it, really if you do not believe me go read his other posts. You continually tell me I need to use the most minimal testing setup, but fail to realize I have. For over a year.. The laptop on battery still displays the same issues at seemingly random times and I have no consistent way of causing it to function better or worst. "Don't pull them. Go to where the phone wires enter the house and disconnect the house runs from that input. Then go back and test them for EMF again." The phone wires never had any input. Those were pulled years ago when we got rid of our landline. They have no input or output on either side. You are talking to me like a petulant child at this point. I have gone "back to basics" 10000 times. I have been methodical. This is not a weeks worth of testing here. It is over a year of consciously using my devices in these homes and documenting most of the strange behaivor I have observed. I do not have access to the proper equipment to diagnose this (spectrum analyzer/oscilloscope). I appreciate that you are trying to assist me but if you do not like what my answers are then do not waste your time. I have addressed everything you ask about and still, somehow I am "running around like a chicken with its head cut off, switching dozens of things around, etc".

Ok my apologies, I struggle with organizing all the information in my posts well as there is just so much that I have observed that seems to pertain to this issue. I am not saying it all does, but it is certainly too many things acting strange. I have dealt with this for over a year so sorry if I did not convey that I have tried the most minimal setup numerous times. The laptop with absolutely nothing attached and with Wifi disabled on it still displays, screen hitching, muddied sound, and varying tracking sensitivity (like my mice) on the track pad. Keyboard inputs are delayed to varying degrees at times. If I walk around the house with the laptop it seems to affect it but not in any way that makes sense. The behavior seems fairly random unless some appliance kicks on (sometimes affects it, sometimes not). This issue is always present here, but the degree to which it manifests varys greatly. On my desktops I have swapped my PSU screws, moved around the GPU in its PCI slot and done some other physical altercations that seem negate the issue entirely for a few hours. It is interesting, almost feels like the resistance is built up and changing something drains it allowing my PC to function properly again. I have tested my PCs with everything else on the circuit off/unplugged. I have tried flipping breakers and trying to narrow what circuit a possible culprit is on, no luck there either. When I am discharging charges from my devices how should I go about that? My setup: 2 high end desktops (Intel i5 8600k, and i5 9600k), gold rated PSU's (Corsair, EVGA) all different cables, NVME SSDs and SATA SSDs 2 monitors (BenQ, Dell Alienware) Mouse connection type is USB. I have tested 7 different mice, and 4 different mousepads. Keyboard connection types PS/2, USB. I have also tried using my mouse/keyboard through the USBs on the monitor. For sound I have tried multiple headphones, speakers, tried using other sound drivers/the monitors sound driver. For monitor connection I use Display Port, but have tested multiple HDMI, DVI, and Display Port cables. Tested on multiple high end power strips/surge protectors and power conditioners, and a Tripp Lite double conversion UPS (1000VA) The UPS reports it is getting proper voltage, and 2 electricians and I myself have measured the outlets in my office for proper voltage. No I am not near an airport. (It is maybe 15+miles away). I am pretty close to a bay, maybe two to three miles away from a harbor. Not very close to radio towers that I know of. I am pretty close to a university. Few miles or so Not near any military ranges or bases. The weather is hard to know if it correlates or not. It rains a lot here this time of year. Like everyday most of the day. Since the problem is so variable in its affects although always there, it is hard to say if the weather is affecting it. I could be near some HAM radio operators, how would I find out? Not near any commercial or industrial factories etc The reason I mentioned the other posts is because they also mention problems exactly like mine. Specifically these 2: https://forums.blurbusters.com/viewtopic.php?f=10&t=3641 https://www.reddit.com/r/buildapc/comments/bafhfe/update_after_years_of_mouse_input_lag_and_other/ In particular the one on reddit, mentions how he can move cables around, touch the PC etc and mouse tracking/speed will change. I explored what happens when I apply ferrite cores to my cable and the mouse changes similarly. So does the display clarity (less blur), and the keyboard inputs. So I know that on my data cables there is something interfering I am having trouble finding out how to measure it though. It seems that it is broadband EMI. Here are some of my other posts: https://www.reddit.com/r/rfelectronics/comments/daz4a7/input_lagdisplay_problems_related_to_bad/ https://www.reddit.com/r/ElectricalEngineering/comments/b9g2is/strange_poweremi_noise_related_issues_in_my/ https://forums.tomshardware.com/threads/input-lag-display-problems-related-to-power.3529408/?view=date

For my desktops (I have multiple all with the same problem, high grade PSUs etc) I only use Ethernet. I have tried Wifi but whatever the cause of my issues is it seems to affect my Wifi in the home as well on all devices. It intermittently goes down and does very strange things, I have used multiple modems, and high end routers. I have replaced every cable up to the ISP drop (ethernets, coax, splitters). The laptop on battery even has issues which is puzzling but if I plug it into the double conversion UPS it works a lot better. One thing I should note here, Wifi settings (channels, bands 2.4ghz, 5hgz, n mode etc) drastically affect my mouse tracking in pretty large ways, on all my PCs. I have tested completely disconnecting my modem so that there is no internet being supplied to the home. Even the laptop on battery. I am in the US, on 120v system. I live in a residential neighborhood and own my house. I have seen this issue at one other house near mine, and have tested my PC across town (and in another city) where it ran flawlessly. Hope that I addressed everything if you want more info I can link you to some other threads I have started that caught a lot more traction. I should add that there are others out there with this problem and some of their posts got a lot of attention. I believe I posted a few in the OP. The main consensus of those threads was that it is interference but most likely grounding issues. I have confirmed my grounding is clean at both locations I experience this issue. I know this is a ton to unpack, this is easily the most complex and illusive electrical issue I have ever experienced let alone even heard of. Thanks for the assistance! Edit: Oh I should add an important bit of info. I started out by calling the ISP, they sent a tech out he checked signal levels at the ISP cable drop (coax) and found there was voltage spikes on the line. He then told me there was voltage riding the line, said hes seen it several times and that it was a problem with the power company. He then went to the living room and bedroom cable boxes and measured 15Volts on the HDMI shield of both HDMI's out of our cable boxes. I am not sure how he took that measurement but it made sense because I have had to replace 2 of the HDMI cables.

Thanks for the reply. No baby monitors or IOT devices other than your standard cell phones, ipads, a laptop, smart TV, blu ray player etc. I do not have an oscilloscope nor the expertise to operate one. Is there someone I can hire to do that? Oh I have tested turning off all circuits in the home but the one my PC is on. Same issue still. I switched my PC to a different room then powered off the circuit it was on previously and still the problem persists. I feel that it is not from my home. Any advice on what the cause could be from the power company?

I am hoping to get some advice here to track down a potential ground loop, or serious source of EMI/RFI (not sure if conducted or radiated). I figured there are some techie folks on here so maybe I can get some advice. I have a host of non destructive computer and peripherals related problems. The issue manifest as input lag (mouse, keyboard), degraded sound quality (muddied, and shallow sound), degraded wireless (throughout the house) and wired internet performance, screen artifacts (noise), and degraded display (hitching, tearing). I have confirmed that it is not hardware related: 4 different PC's (Windows 8.1, Windows 10, and 1 laptop (Windows 7) 3 Monitors Multiple Keyboards, Mice, Headphones, Speakers Multiple Modems, Routers, and all new cables (shielded and non- shielded Ethernet and Display port cables do help slightly I believe. Observations: Using different circuits and configurations (power strips, or conditioners) around the house which changes the input delays and performance. Moving cables away from each other helps even data cables are messing with each other. Placing a phone on PC makes the mouse sensitivity feel two times as fast. Placed ferrite cores and toroids onto data, and power cables changes mouse tracking, sound and display quality, and internet performance. Different power strips, Gold and Platinum rated PSUs, a Furman power conditioner, and a Tripp Lite double conversion UPS. UPS does something makes the input latency better, and the power conditioner helped for a few days. The power conditioner helped the most with the sound and display issues. Seems to be better at night but only slightly. When an appliance in the home is switched on the amount of data latency, input lag and display issues amplifies. Any setting in Windows or BIOS changes how the mouse preforms (power settings, and fans speeds do the most), however after some time it seems to degrade back to the same point. Wifi in the home continually cuts out and some weird stuff like if my modem and router are one the same power strip the Wifi will not work. Desktop PCs connected to Wifi even two feet away from router makes the input latency lower however there is full one second stutters in games, browsers and video streams. Used my PC at a friends house in another city and it works perfectly fine, night and day from my setup at home. I am actually shocked at how much deeper sound, colors and consistency of mouse tracking is compared to at my house. I have had the power company out twice, and had two electricians check my grounding, neutrals, and outlets. All come clean. I poked around with an AM radio and while there are some sources of noise around the house, nothing stands out. My laptop on battery works better at random times yet still has the same issues. Found several posts relating to the issue and it seems they all observe the same symptoms: https://linustechtips.com/main/topic/1055893-power-issues-can-cause-input-latency-issues/ https://forums.blurbusters.com/viewtopic.php?f=10&t=3641 https://www.reddit.com/r/buildapc/comments/bafhfe/update_after_years_of_mouse_input_lag_and_other/ http://www.jonnyguru.com/forums/showthread.php?16546-Major-input-lag-caused-by-Power-issues-in-House I have tried a few power conditioners (Furman) that work pretty good for a day or two then its back to the same old degraded quality. I believe this is similar to what I have seen with ferrite and toroid cores in that they seem to saturate and once they do the filtering qualities are pretty much gone. Now this is where it gets interesting. I have a Tripp Lite double conversion UPS which helps a bit with the consistency of inputs and the display quality but ultimately the issue is still entirely there. This does not make much sense if the problem truly stems from the power company but one thing I have noticed is if I pull that plug for my UPS, then for the few minutes I run truly off of battery, everything is perfect. Then when I plug the unit back in the lag comes back fully within a minute- almost like it builds up resistance or something. I believe what is happening here is by unplugging the unit (UPS) I am effectively floating the ground which seems to be the source of the issues here. In a double conversion unit like mine the only thing that is not filtered is that passed through connection to ground. I have spoken to other folks with Online UPS and this very problem and they say the exact same thing. Now I am not sure how the ground connection could be faulty in some way, and simultaneously measure clean at the panel (verified with two electricians using a clamp meter). After reading several posts about this very issue and seeing first hand how ferrite cores, moving cables, and power conditioners etc affect it I have concluded that it is indeed an electrical noise issue in my home or from the power pole/utility. In the thread on r/buildapc some of the comments stated it is likely an issue with grounding. I am wondering if maybe an Isolation Transformer, or just lifting (floating) the ground would solve it. If there is anyone that is knowledgeable in these areas of either breaking groundloops, or at least finding them, or dealing with finding sources of EMI and finding out what frequencies I need to filter please let me know. I understand any skepticism about what I have posted here as it seems absurd to me as well but it is the truth and I would love to know what the cause is and how it can affect digital devices in these ways. Thanks

Power company has come out twice to inspect the line to the home and to check the electrical meter. The first time I believe they replaced a cable or something. Second time I was present for and I asked they guy after he shutoff the power and ran his tests, he said any issue was gonna be on our side and is not the power companies responsibility. I hired a really good electrician after that and he said that its likely the power company does not want to assume responsibility but he could not conclusively say what the issue stems from. After checking my panel and all the lines he says the house, neutrals, grounding etc looks clean. I am gonna have him out again and see what he thinks about the fact that floating the ground on my PC and UPS fixes it. I am in the US by the way and we only have a government ran power company here.
