Dell Alienware AW3423DWF 34″ QD-OLED 165Hz FreeSync Premium Pro (3440 x 1440)

I was in accurate mode, but just tried it now in reference and it still clips at 510. Very strange stuff. We'll see what happens when ever they release another firmware.

If the problem is also on the DW.... I really wish they had went with DP 2.1 for the DWF.
Started getting black outs with auto switching off now… hoping it’s just the cable. Swapping em out again now.
 
The Amazon basics arm works great in the DW. Would assume it works great on the DWF considering it's lighter.

How do I tell for sure whether FreeSync on this montor works with G-Sync? On my Windows 10 installation, "Variable Refresh Rate" does not come up in Windows OS Graphics Settings, but it does on my Windows 11 installation.

I assume that if "G-Sync" is selectable for "Monitor Technology" in NVidia CP, then FreeSync is detected., but NVidia Pendulum demo does not let me select G-Sync... Is there a way to know for sure???

If "Enable settings for the selected display model" is enabled in nvcp under Set up G-SYNC, then it should be on. Make sure also that Monitor Technology is set to G-SYNC, G-SYNC Compatible under Manage 3D settings in nvcp. If you want to make sure it is indeed working in game, turn on the monitor framerate monitoring in the OSD under Game, Game Enhance Mode, Frame Rate. Launch a game and see if the frame rate is going up and down. If it is, then it's working.
 
Blackout free with the included cable still so it looks like the monoprice dp80 cable is just junk.

We just had our power go out during an ice storm and I noticed something interesting about the display. It screams like coil whine but at least ten fold worse when on battery backup power and I’m wondering if people reporting coil whine just have an issue with their wiring or something. Never heard a display scream like this before on an UPS. Gotta be some of the worst harmonics I’ve ever heard from electronics.

Another interesting thing I stumbled over was Vincent’s video of the Sony a95k QDOLED which sure sounds similar to what we are encountering with in hdr 1000:


Clips in the 500s during calibration on consoles and has the overly bright eotf tracking.

That's good news about that cable! Glad your DWF is not defective.

Another interesting find indeed about the coil whine! Sin Wave UPS would be ideal for this then.

One has to wonder if the manufacturers have been relying on some erroneous technical documentation about HDR1000 then.
 
Yea I think you're right, just a heads up Hellblade Senuas sacrifice look beyond amazing in hdr on this panel. I was playing it a bit and man when they focus on her face and the rest of the screen goes black. It's amazing looking.
I just started playing it and you're right. That game was made for this panel or that panel was made for that game! Either way it really show case the amazingness of this OLED screen.
 
So far I don't like HDR in any games on this or any monitor because HDR modes crush detail. For example, Uncharted 4 looks horrible in any HDR mode. Thankfully, OLED makes SDR look incredible without loss of detail.

I finally got VRR to work. I had to wipe OS to get it working on this monitor, no idea why, but it wasn't working at all until fresh OS install.

This reminds me one of these classic claims when people tried "HDR" all the way back in 2015. Even now there is still one or two claims pop up on Youtube.


These claims of SDR>"HDR" is not far from the truth as the "High" dynamic range on their monitors is tone-mapped all the way down lower than SDR range.
When the overall "HDR" is cramped down to 400nits, there is no way to create high brightness, high color gamut when a monitor is only able to create a 400nits sun as bright as yellow as a pin pong ball.
You cannot get actual contrast where the 400nits sun against 0.1nits shadow 400:0.1 vs 2000nits sun against shadow 2000:0.1.
But you will get "crashed" details where the supposed 100nits ground against 1nit shadow 100:1 is tone-mapped down to 15nits ground against 1nits shadow 15:1
High Light A-B compare 33.3%_2.png

In the end you won't see that much contrast the creator indented. You won't be able to see these 2^10 or 1024 shades of 10-bit color when it is cramped under 400nits instead of 1000+nits. However you can see the vibrant simple 8-bit color on SDR when it is not cramped..
This is why Dolby doesn't even bother to use its algorithm on sub-HDR displays. It will just look worse compared to original HDR 10 static clipping content. It looks even worse than 400nits clipping SDR.
This is exactly where these claims comes from on 400nits "HDR" monitor even with infinite contrast which is just a relative contrast against 0nits with no color.

Another classic defense is to cramp SDR to 100nits sRGB so it definitely makes a difference compared to 400nits "HDR" that is still in the SDR 8-bit range.

Pretty funny Uncharted 4 looks rather dashing instead.
What is even funnier is people buy RTX 4090 but claim there is hardly any difference with Ray Tracing on the Witcher 3 because they cannot see the RT shadow against the ground due to contrast tone-mapped too low on their monitors.

pulled the trigger on a DWF today as a xmas present to myself. Saw one in person at a LAN two months ago and here i am still crushing over it.
Pretty excited as i went from Dell 2407WFPs to the Asus monitors i have now and the difference was negligible.

Is AW3423DWF one of the monitors that can't get 1000nits to display HDR correctly? I never quite figured that out from reviews. I've seen HDR content on LG OLED TV in Micro Center and it looked marvelous compared to SD version shown right next to it, but because of all the HDR issues and disputes, I only cared for calibrated SDR sRGB image + excellent black levels + great motion, where nothing was clipped, everything was compatible with existing content, and brgithness was not hurting my eyes. This monitored delivered just that.

The worst part about this monitor and QD-OLED technology is that it needs very expensive spectrophotometer (5mm of better) to measure color accuracy. i1Pro 2 or i1Pro 3 are not good enough. You either have to invite a pro to either calibrate QD-OLED or profile your colorimeter or buy $15000+ equipment.

It can display HDR 1000 correctly at 2%-3% window. HDR needs a lot color at higher brightness.
Anything more than that it needs either tone mapping or just clip through.

Actually... a lot of people with spectrophotometers already generated required files and are contributing it for free on the internet:
https://colorimetercorrections.displaycal.net/
You have to search for aw3423dw instead of dwf but panel is exactly the same so I bet nobody will be complaining. How come i1pro2 is not good enough? It can generate 3.3nm spectral correction. I have used sRGB Creator mode and calibrated it with DisplayCal + i1 Display Pro Plus + spectral correction from displaycal database and color accuracy is bonkers. This is one of the best sRGB monitors ever.

AVS forums pro calibrators say QD-OLED spectral spikes are too narrow for i1Pro 2, but those guys need to make money to pay off their debts on their Jeti's and Minolta's. They do mentioned DisplayCal database and even post EDR/CCSS correction matrix files for QD-OLED panel type (made on some Sony QD-OLED).

How accurate/inaccurate is i1Display Pro's generic OLED SDR preset/profile compared to correction files in that database? How accurate/inacurate is Dell/Alienware's factory SDR calibration compared to personal measurements?

My visual (not measurement-based) observation and comparison to my calibrated CCFL LCD monitors goes hand-in-hand with what Dell/Alienware factory report says and what pro reviewers' measurements show. Gamma is the main issue. It uses a BT.1886-like curve but with of 2.2 instead of 2.4. The result is that some dark grey detail is washed out. It doesn't have much of a negative effect in games as it does in films. Gamma setting of 2.2 setting the only gamma setting that is calibrated. Increasing gamma it to 2.4, 2.6, or decreasing it to 2.0, results in first 1-5 black levels being crushed. I think Dell/Alienware uses factory service menu and calibrates 2 specific modes (one for HDR and one for SDR) for specific settings, disregarding natural setting progression of all other settings. Gamma 2.2 setting value is just too unique and too much of an outlier compared to other values.

FYI, HDR and SDR modes are treated as separate monitiors devices by Windows OS. Switching between Standard and Creator mode while playing a game can crash it because OS switches monitor driver.

This monitor is indeed awesome.

Calibrator there says REC.2020 coverage on 55” & 65” QD-OLEDs are far wider than the 34” on AW3423DW & DWF, is that true?

Would QD-OLED 2.0 offer wider gamut coverages and higher peak brightness than this year’s too?
 
No idea, but every year almost all technology improves. As such, its more about getting the right piece of tech at the right time to love it long-time.

New cable started losing signal as well. :(

I’m starting to think nvidia drivers might have bugs with freesync / gsync implementation. The dell thread for it on the dw has people rmaing 3-4 times before giving up and Reddit has about 3 years of posts for various displays both freesync and gsync having this issue across 2000, 3000 and 4000 series. All sorts of voodoo switching cables, changing refresh rate range with cru, running lower bit depth or without hdr, avoiding shaking the desk… nothing consistent that’s for sure. lol

Seriously doubt it’s the 3080 as it was fine all year with the prior display. Interestingly nvidia released a uefi update for 3080ti and 3090ti for black screens / signal loss over dp 1.4 but nothing for the 3080.

I guess I’m down to running with vsync instead to see if it occurs.

Well that sucks :(

You know, reading you, I have been experiencing these black out on my old AW3418DW for years now; it only happen when I stand up from my chair and move away from it. It never bothered me since it never happened while actively using it. I always though it had something to do with a loose connection or me moving the cable around when standing up or something. It happened on a 3080 (TUF Gaming OC 10GB) and possibly a 1070, although it has been a while since I've used the 1070 so my memory may be fuzzy on that one, on an Intel and an AMD system.

Did you try using all the different ports on the back of your 3080 ? Being on a 3 display setup, I had to shuffle around my cables to get the monitor order right so that the DWF is display #1 in Windows. Interestingly, when booting, the active display is not the DWF, it's one of my side screens; all three are plugged with DP. May not be related at all, but I'd though I mentioned it if it can gives you troubleshooting ideas.

If NVIDIA released an update for something similar... Did you look around on Nvidia forums, did the problem they fixed for the 3080ti and 3090ti had the same symptoms as what you see ?

Going down the Gsync/Freesync path and just a bunch of generals ideas you could try if you feel like it:
1. Windows 11, under Gaming play with all the options there, on and off: Game Bar, Game Mode, GPU Scheduling, Variable Refresh Rate, etc. / I have everything at "on" except the Game Bar which is "off" (which still works in game anyway for some reason)
2. Make sure Resizable BAR is enabled and functional (see GPU-Z)
3. NVCP, try all combinations of G-sync settings.
4. Geforce Experience, disable/enable In-Game overlay.
5. Running MSI Afterburner, or HWinFO, is your GPU clocks behaving as expected: downclocking when idle for example, etc. / I run a custom under-volt curve on my GPU with Afterburner with a maximum frequency cap of 2040 at 1000mV, power limit at 90%.
6. Did you plug the DWF usb cable ? / Mine is plugged in and I use the screen as a hub for my webcam.
7. Did you try running the Dell Display Manager app ? / I don't run it for the moment, waiting on HDR 1000 fixes before I fiddle with it
8. As mentioned above, figure out which port is Windows port #1 for the GPU and use that one.
9. Hope the January DWF firmware somehow fixes it for you ?

It’s funny you mention moving the chair. I asked some of the devs I work with if they seen this before and apparently since 2018 they’ve been tracking it with nvidia gpus across 10, 20, 30 and 40 series with gsync and freesync displays. Pointed me to their big ol slack threads about it. But one of them absolutely swears by it being whenever his chair moves and he gets some floor flex which shakes the desk. I’ve tried tugging on both ends, wiggling the connectors and shaking the desk and monitor but can’t reproduce it that way at all. Not a single amd card affected amongst any of the rigs they’ve seen it on.

I am also running the 3080 tuf on this setup. Currently on port 1 for both the display and GPU. I have yet another cable on the way for testing that’s passed the LTT cable tests so I’ll try swapping ports around if it occurs again on that one.

For the 3080/3090 ti firmware update I’ve seen a lot of complaints about 3080 and 3070 users left in the cold with the problem and no fix. Looks like it resolved it for the ti users though or at least not much mention of it anymore.

It’s also tricky to discern if people are encountering black screen flickering or actual signal loss or maybe the handshake is so fast it’s signal loss but all they see is a brief black flicker or even gamma curve VRR flicker. I’ve seen numerous videos of both where the issue is a very brief almost single frame or two that’s black timing wise or very long bonks like signal was lost or it’s switching modes / doing the handshake again.

Neo and regular G9 seem to be the most common displays with the issue reported but it spans a pretty large amount of other ones. Even dell has a KB article for several of their adaptive sync displays blaming nvidia and the windowed mode gsync:
https://www.dell.com/support/kbdoc/...olve the flickering,play games in window mode

I was originally running windowed and full screen for a few games that weren’t enabling gsync in borderless window but the desktop VRR flicker was bothering me enough to go back to full screen only. It’s also pretty unclear if they mean flickering like we see with VRR flicker or actual black screens here.

Also interesting is every post about it I’ve dug up as been basically nvidia users. Haven’t seen a single mention of AMD recently. Some old references to a driver update to address black screen flickering.

I’ve also seen a lot of threads suggesting CRU to raise the refresh rate range but I’m highly skeptical anyone would release a monitor that can’t handle its adaptive sync range advertised in the EDID meta data. Most of those end with the problem coming back eventually anyway. Regardless I’ve tried reproducing the issue running the gsync pendulum demo with min frames 20 and max frames 168 which I’d expect to show the issue if that was the problem. Absolutely nothing.

No events in event viewer that would indicate GPU drivers crashing or anything else at all for the time frames where it occurs. Afterburner looks normal idle and under various loads.

The aw3423dw(f) specific threads have a mix of users who RMA and the issue is “solved” and those who RMA several times all with the same issue. Makes me rather skeptical that it’s the display itself. Considering how infrequent it has been I’d say you’d probably need a few months to rule out if it’s truly gone or not. I’ve gone weeks without it occurring so it’s definitely miserable to test.

Between trying to minimize the variables and deal with the incredibly long time between seeing the issue reproduce I’m down to 1) test with a fourth cable and 2) if it occurs again test with gsync disabled and just using vsync. If it occurs without gsync then it’s probably down to trying the ootb timings for 100hz 10bit or 165hz 8bit to see if there is a difference.

I can't explain the chair phenomenon either. It's not even instantaneous; I have time to get up, move away and then from the corner of my eye I can see the screen blinking. I've seen this time and time again, always the same. I think only once in years have I seen it happen while I was still sitting and looking at the screen. Quite an esoteric thing.

Since we got the same card, here's a picture showing where I'm plugged in using a 16K cable I got from Amazon a couple of months back. The other two ports beside the DWF are used by my other monitors.

I'm certain I've never had any signal lost issues with the DWF; no strange mode switching or handshake when it shouldn't do any. The DW I had from the first batch they sent out though... that one was having issues with handshakes; it made my PC crash when rebooting for example. Anyway, that's another story. Either way, with the DWF or DW I've seen my share of VRR gamma flickering; so far that has been my biggest downside using OLED monitors.

Yah, intermittent problems are the worst. You're running at 144 10 bits if I remember correctly ? I've been using 165hz 8bit most of the time or 120hz 10bit when using DLDSR.

I am running 144hz 10bit still. It’s interesting you mention 120hz 10bit because I was thinking about this earlier:
https://www.reddit.com/r/ultrawidemasterrace/comments/yvdlcb/aw3423dwf_refreshrate_explained/

Which would technically cap out at 121hz when you crunch the weird H and V active numbers. Yet when we look at EDID with CRU it’s the normal 3440x1440 for both H and V active instead of 3520x1712. I would however expect the handshake to outright fail with HBR3 if it was actually 3520x1712 144hz 10bit and surpassing available bandwidth.
 
Edit: Nevermind, the beeping sound was an actual alarm clock inside my room that I didn't even know existed...

The "Game Enahnce" - "Frame Rate" mode is a true indicator of FreeSync G-Sync working. If the Hz number changes in your games, then G-Sync/FreeSync is working. If Hz number stays the same, then G-Sync/FreeSync is not working.

I can't explain the chair phenomenon either.
My guess is that it has something to do with a static charge that is generated by moving the chair back, getting out of it, and walking away. The charge is going through the floor and into cables that are somehow connected back to the system. My PC was doing this for years until I recently moved from a surround sound system with speaker wires running on the floor to a stereo setup with no wires on the floor. It could have been a coincidence but it's worth trying to see what happens if nothing connected to your PC is touching the floor.

I do happen to have a Logitech Z-5500 in place which surrounds my desk; a perfect antenna indeed. Maybe that's what was causing this. I did raise the cables so I wouldn't see them though. Two of the speakers were directly touching the back of the screen too. Either way, that or something similar is the most plausible explanation for that phenomenon I've heard yet.

Shouldn’t this be non-issue if it’s all grounded?

Hasn’t been a single instance since my last post making it all the more frustrating to narrow down when it takes so long.

It should be a non-issue, but I can't come up with any other explanation for the chair effect.
 
Got this dell link from reddit; looks like a firmware update will be coming mid Feb: "A permanent solution with a new firmware update is currently under development with an ETA around middle February 2023."
 
Hmmm. I have hard wood and it’s relatively high humidity so it’s about the last thing I’d have expected but the oem cable was too short to route down the desk frame and leg. All the cables I’ve had the issue with are along the frame and I just checked the uplift desk’s plug and it has no ground. Seems plausible enough running along the frame could be the issue and I haven’t had it happen yet with the third cable that’s dangling free not touching anything.

There is also this about EMI leading to ESD on monitors:

And my chairs do have gas lifts.
 
Mine arrived today, had to replace a lg 34gk950f that died in less than 3 years.

So far loving it, no stuck/dead pixels. I know nothing about HDR but maybe its time to look into that.

It went on sale on the dell site between my order and delivery. Waiting on a support ticket to see of they will price match.

Another post about the dwf blanking when sitting/standing:
https://reddit.com/r/ultrawidemaste...lienware_dwf_flashing_black_when_standing_up/

I suspect I might have figured my issue out. When I route the cable along the frame it passes right next to the electric motor in the leg. Not an uncommon source of EMI. Don’t know what else would explain it.
 
Does anyone know if you have to register this monitor with Dell to have Dell honor its warranty policy regarding burn-in?

Why would you not want to register it ? Do you have a DELL service code ? If you do then you're already registered.

I just had it happen on my DWF when standing up from my chair. Had Hi-Fi RUSH running and the screen blinked. My AW3418DW right beside it didn't do it at that time. As long as it's harmless to the screen, I wouldn't worry too much about it.

I’m just happy to conclude an RMA would be a waste of time as I really didn’t want to go there with an otherwise perfect unit well past 30 days. Still annoying though as I get sometimes in the middle of doing stuff but it’s pretty rare.

What chair are you using btw ? I'm using a SecretLab Titan 2020 Softweave, which I love btw; it helped a ton for my lower back pain.
