So, just to double check all the troubleshooting I have done thanks to the information on this site, I'm pretty sure my 3080 ti is the cause of my issues. I am having screen flashing and most time it just plain ol looses signal. At first I thought it was my monitor but I confirmed it's not by switching to integrated graphics and swapping the GPU for a 3060 ti I have in a different build. It's so random. Sometimes it works, but recently it's been throwing a hissy fit. In the beginning I assumed it was driver related because it stopped doing it but it's been spotty the entire time. So just to cover my steps, I have tried multiple different cables on both hdmi and DP. It seems to work better with HDMI, but will not show me BIOS half the time. I pretty much get no signal until I move my mouse after it's been booted for a while. Really strange. On DP, I get screen flashing and like I said earlier, it just looses signal randomly. Sometimes I retry after 15 minutes and restarts, shutting everything off and removing cables and it's hit or miss. I've tried different drivers, flashing, everything... nothing fixes it. Well, this sucks. I do have a support ticket open so hopefully I will hear back from someone because I cannot start an RMA until I get a support ticket number. Probably should have sent it back sooner but I never really started troubleshooting because it just recently got really bad to where I had no choice but to find the source.

and/ or - have you loaded PX1 & let it do the 2 firmware fixes on start ?

you want a DP cable that is Certified (they Do Not have to be expensive cables)  ... the generic DP cables out there can cause all sorts of issues

Are you running windows 11?
My system was fine until i went windows 11 and the new Nvidia driver.
Also have a support ticket open, so please update if you get an update.

So I got home, redid the cabling, and had 1 screen flicker. I went into NVIDIA settings and noticed it was on YCbCr422 with a limited dynamic range. My monitor will do 144hz. However, I prefer the 120hz RGB 10bit option. At 144hz it pushed 8 bits. I notice the difference in the daily work, but obviously not in gaming. Movies do look a little better too. Anyways, I reverted back to "default color scheme" and have not had a flicker yet. It recently started going haywire after updating to the newest driver, so I reverted back to 472.12. I was also experiencing crashing in RDR2 with it. TBH, the last thing I want to do is go through an RMA especially to have it kicked back. I am trying everything here to avoid it. I don't understand why resolution tab was changed but right now I have it in 144hz default color setting. I am going to try and keep it there and hopefully it doesn't flicker.

What are the odds this can be driver related above all else? Assuming even with a clean install something is still wrong from updating to 496.13. Should I uninstall the drivers in safe mode then reinstall (472.12, not 496.13)?

Will do. Hopefully it's driver related. This is what we get for wanting control over our shader caches for the past 10 years...
 

I'll give them a shot. 2 days and no issues. Maybe "certified" is something I overlooked? I dunno. Really trying everything to not RMA this. It's quite possible the DP cable got pulled some awkward way. I gave it some slack and never had a problem with 472.12 before, so I doubt rolling back to it had anything to do with it. There are so many variables here and diagnosing the cause of the screen flickering and cutting out stresses me out. $1400 monitor and a $1500 GPU, so I hope it's just a $20 cable.

Yea it should have never been in YCbCr422, so not sure what that was about. Ever since I updated the drivers it's been doing this. I did a clean install of 472.12 but I think it uses the new phys-x stuff. I am wondering if maybe that has something to do with it too. I wonder if I totally uninstall again then just install 472.12 if that will keep the correct phys-x drivers too. TBH, I have no idea what the phsy-x drivers even do.

Another update is Q-Code d6 when booting, which in the manual is related to the GPU. Any ideas on this?

So, I requested a ticket number to put in my RMA but I really want to be sure it's the GPU. I got two new certified DP cables on the way that won't be here until Friday. I have not formally requested the RMA, so am I okay to wait a bit?

I am also not ruling out the Display of course. It is an Alienware after all... So I guess when I "confirmed" that it wasn't by switching cables that really isn't confirming anything because it was limited to 85hz on HDMI. I'm on the fence about getting a Gigabyte Aorus fo48u that is a 48" OLED, but tbh I am not fond of Gigabyte components (even before their PSU issue). The other option was an Alienware 55" OLED for almost double the price. LG has a similar option too, but is unobtainable currently and is 65"! Maybe too big for being 2 feet away from (most times). Anyways, getting an RMA through dell is like pulling teeth. I already had to RMA my 10TB WD Black drive and that is currently in the process of getting looked at. So I'd really like to avoid RMAing anything if I can and I'd like to just use the 48" OLED as a secondary.

I also have custom cables from cablemod they made for me using the configurator. I swapped them out with the stock cables for the GPU that came with my 850P2. Did the usual... a day or so and started the same issues, so, not the cables. That was honestly my first suspicion. 

Maybe I should try the monitor at 60hz? Or I can swap to my LG 32GK650F-B I am using for the secondary PC in the other spare room and try that for a couple days? Lots of troubleshooting to still do and it could take time I guess, but I wrote a list of all these things to try so far and what I did try already has been covered here in this thread. Between working 50-60 hours a week right now, I just don't have much time.


Anyways, any more help is appreciated. Really curious what the Q-code d6 is all about. Thanks again everyone.

Yea bios is up to date. No local shops where I live. I'll test it in my 10400/3060ti setup
