Hello, I recieved my 3080 10 days ago as of the sending of this message.
Immediately I noticed flickering at the top of my monitor as shown in the attached BenQFlicker.mp4
This flickering is not happening and has never happened on my Geforce 2070 Super.
At first I was worried I had a defective graphics card so I started troubleshooting, I found out it only happens on Displayport, on all 3 ports from the card on all 3 of my monitors, I tested it with 5 different cables in all 3 ports and all 3 monitors, the problem does not occur through HDMI.
I went into my BIOS and the problem also happens there, this rules out any software issues in windows that could cause this, the next step was to test it in a friends computer, I did and there was no problem so I then thought there must be an issue with my computer that manifests itself with the 3080.
I have done several full clean driver installs, reseated the card several times, made sure my PSU cables work and are seated properly. I was using the newest driver at the time and have for now stopped using the card, from what others have experienced the 465.71 drivers have not helped. My monitor does not have Gsync or Freesync so it was not caused by this issue.
I put a post up on Tomshardware and the other day another person chimed in, he has two monitors and one of them is the same brand and model as mine and has the same flickering issue down to the pixel and his other monitor does not, his issue is also only through Displayport. His issue is shown in BenQ Flicker 2.mp4. Changing to HDMI also fixed his problem.
The monitor we both have is Benq GW2765HT, I have 3x of this monitor and the issue is the same on all 3.
At that point it feels like we have it down to an issue with with the specific monitor or panel, I have also sent a message to BenQ about this and am waiting for a response.
Yesterday another person chimed in with a flickering issue, his was a bit worse than what we had and was on an ASUS PB277Q, it also resolves itself when he plugs it into the HDMI, however he was able to sort it by changing Displayport mode from 1.1 to 1.2 on his monitor, mine also has this option but is default to 1.2 and changing made no difference, his issue is shown in ASUSFlicker.mp4.
So it seems to not only happen on one monitor, but this is definitely an issue happening between some monitors through the displayport signal, and as more people get these cards I am sure more reports of it will come in, considering this is likely to affect the entire line of monitors of the type that I own as I have 3 examples of it and found another example.
I looked for similarities between the BenQ I have and the ASUS of the third person and found this:
The panel is made by AU Optronics and are not the same panel, but going from the panel model they could be in the same panel family as they are differentiated by only one letter, the BenQ is IPS and the ASUS is TN, so I assume that that letter signifies.
BenQ Panel Model: M270DAN01.0
Asus Panel Model: M270DTN01.?
At this point I have very little doubt that there is some correlation here and it would be quite bad if entire lineup of monitors based on a panel or possibly another specification that should on paper work with the 3080 ends up not working, I ask of you what I asked of BenQ to look into it and see if this is something that could possibly be fixed on a software level.

Hello ****, thank you for the quick response.
I have done everything you asked and hopefully done it correctly, files are attached as you requested.
This is all done without the 3080 connected mind you.
I have an additional thing to add that I forgot in the initial message, when I use a displayport to HDMI adapter the problem also seems to go away, I tried this with an old adapter that can only do 1080 but I have some active adapters rated for higher coming in next week that I will test on. It does seem that if the signal is converted to HDMI the signal becomes stable even if it originates from Displayport.

Hello
***,
Thanks for the update.
I am sorry, I should have been more clear. I would need you to generate the reports with your RTX 3080 installed. As we would need the logs with the card installed. This will allow us to figure out what is causing the issue, and debug it if necessary.
Once again, I apologize for making you do it again. But it is required.
Looking forward to your update.
Best Regards,

Thats fine **,
I will do this in a few days when I get my adapters, that way I can put the card in permanently and use it with the adapters after I have supplied your info, hope that is ok.

As requested by the previous customer rep I talked to I would like to reopen case #*
You can read the full extent of the issue there, it took me a while to get back about this because of some serious delays in the postal system so I didn't get the parts I needed to permanently install the card again.
I am supplying the bin and nfo files as requested, one of the bin files have a monitor connected through HDMI which works, two through DisplayPort which has the bug.
Since then I have gotten several replies of people with the same issue on the exact same monitor as me on my topic at Tomshardware, I will supply a link at the end of this if you wish to look.
It does however seem my theory about this being a panel family issue is debunked as someone with an ASUS PB278 arrived showing the exact same issue with the exact same issue, this monitor uses a Samsung panel from what I know, he has a video in the TomsHardware topic.
Videocardz.com also tweeted about my topic and we got one person with the same problem on a BenQ monitor there as well.
This now provides us with a few samples of the same monitor displaying down to the pixel the same flickering on DisplayPort which is solved with the same solution, using the HDMI port or a Displayport to HDMI Adapter

Hello
***,
Thanks for the update.
I just went through your previous notes, and one thing that caught my eye was "I went into my BIOS and the problem also happens there", which I had missed last time. Now, if the issue is happening in the BIOS screen as well, and also with the conclusive fact that the issue does not happen on your friend system. It looks like the issue could be due to your Motherboard itself.
BIOS is a firmware on your Motherboard, which is independent from not only your windows but also any other hardware on your system, including GPU. Only, RAM and Processor can cause issue on BIOS screen, but definitely not the GPU.
Upon checking your system information, I found that your BIOS is very out dated, in fact it goes back to 2015. I would request you to get your BIOS updated. Also, contact the motherboard manufacturer once, and get their insight on this issue. Inform them that you are having issues on BIOS screen as well.
Looking forward for your response.
Best Regards,
NVIDIA Customer Care.

Hello, I appreciate the feedback about the MB BIOS and I had thought about it before, I don't think it would be the issue as I now have so many examples of people who can replicate the problem 100% across different systems and it is specific to certain monitors, all but 1 report of the exact same flicker being on this model of BenQ.
I am building an entirely new computer that will be done in a few weeks once the new Ryzen CPUs release, and I expect the problem to be replicated there. If not for this I would update my BIOS to test but I rather not mess with my system too much at this point, as I also find it highly unlikely to be the issue.
And while it showing in BIOS proves it is not an issue with the GPU Driver, it does not exclude a hardware issue or GPU BIOS Issue, in fact back in 2018 Nvidia did a BIOS update to the Maxwell and Pascal architectures to support DIsplayport 1.4 and 1.3.
Further the fact that the problem is fixed when one changes to HDMI or converts the DisplayPort signal to HDMI with an adapter to me further points towards an issue with the card sending stable DP signals to certain monitors or panels, or connections. Of course I can not dismiss that this could be a problem on the monitor manufacturers side.
I have one update where a forum user did some testing and I replicated it with same results.
Creating a custom resolution in Nvidia Control Panel and setting the FPS to 59 instead of 60 makes the flicker happen less often, but makes it appear on the bottom half of the screen instead of the top one. This further suggests to me that this is linked to the GPU and not motherboard.
While of course I can not totally dismiss your claims about an outdated MB BIOS I hope you consider how unlikely it is considering how replicated this issue now is across different users.
Thank you.

Hello
***, Thanks for the update. No, that is highly unlikely. BIOS is the main firmware of the motherboard, if it outdated, it can cause issues with any hardware component connected to it. We cannot completely rule it out, until and unless we know its the latest version.
Also, the reason I don't feel its the cards, is due to the fact that it works absolutely fine on your friends system. Which means the DP port are sending across the signal fine. If it was an issue with the DP port, it would have done the same with any other monitor. Also, the previous issue with DP 1.3 and 1.4 has already been fixed from our end, with the firmware update, and it was a known issue. However, here I can confirm that the issue you are facing is not a known issue or a Bug, or else there would already have been a bug reported. So, that brings us down to only to probable suspects. Either your Board or the Monitor. And I agree with your theory of it being an issue with the monitor itself, however we cannot comment much on it, as its not our product and may be the monitor manufacturer would have better understanding about it. This is supported by the fact that other users are facing similiar issue, however we do not have any data to confirm if they are running with the BIOS updated to the latest version aswell. However, if you are not comfortable updating the BIOS, you can wait till you setup your new system. Menawhile, you can get in touch with the monitor Manufacturer and have them check this aswell. Please feel free to contact us for further assistance, we would be more than happy to assist you.

Hello again,
So, I am aware the DP 1.3 and 1.4 issue is already fixed, it was simply an example of how issues can be outside of the driver and still be GPU related.
This may as you and I both agree on be a monitor manufacturer issue, but it seems to affect different manufacturers and different panel families, the problem was introduced with your series of cards and is not present in any other series and so I would argue the responsibility lies with you to either fix it on your end or on you to contact these manufacturers and have them push a firmware update for the monitors to fix it.
You say it is not a known issue or bug, that may be but I counted and I so far have collected testimonies of 9 people who have the exact same problem, the flickering behaves in the exact same manner and the workaround is the exact same. I have more flickering reports but they are not exactly the same so I am not counting them. It is a possibility a lot of people just return the cards as faulty instead of reporting it to you, also with the relatively low amount of 3000 series card that have managed to ship out there is not a massive sample rate of people that end up taking the time to troubleshoot and report the issue, especially as it seems to only affect certain monitors.
The monitors so far recorded as affected are these:
BenQ GW2765
Asus PB278
BenQ BL2420-T
The majority of reports I have gotten are on the GW2765, the rest are singular.
Because of your claim that it would be my outdated BIOS or some other hardware issue I asked people what motherboard and BIOS they have, I have so far gotten 2 replies and they both have newer MBs than me with the latest BIOS updates and still experience the issue.
So far I have spent a lot of time to troubleshoot this and rally people with the same problem, several of them were about to RMA or return their cards to the vendor as defective when they found my topic, I have effectively saved you and your partners returns, I have also spent money on adapters for the workaround for this at no small expense to make sure I am reporting properly and so that I am able to use the card.
Now, I understand your job is to exhaust other options before escalating an issue and my outdated BIOS raised a flag for you, but I feel I have proven your hypothesis wrong and with my not insignificant samples of other people with the same issue, and the fact they have newer hardware and BIOS.
You can chose this as your hill to fight me on, I can wait for the weeks it will take before my new CPU releases so I can build my system and I can come back then with the same issue, but when I do I will make sure it is reflected in my review of the support given, considering the considerable effort I have put into troubleshooting the issue and gathering testimonies.
I apologize for the slightly more hostile tone in this response, but I do not appreciate being given textbook "Have you turned it off and on again" responses to problems like this that I have detailed so well.
Please read and understand the report in its entirety and get back to me with your decision.
