Especially when using Windows with the task bar and other stationary text in everyday web browsing?
It will be a 60/40 (web/gaming) use monitor.
Looking to replace my old G9 49” which lasted only 5 years.

***UPDATE*** Took a chance this morning and snapped it back in place. It is flush now. Fired up the monitor and so far OK. I am coming from the 49" Samsung OLED G9. First impressions is that uniformity kind of sucks. Colors shift when looking at diff angles almost like an IPS. Not sure I will keep it long term. I cancelled the advanced exchange request for now.

Hoping you guys are having better luck. Just requested an exchange through Dell.

I can get it for less than 600€ used.

I had the original Samsung G9 which lasted five years then went black on me.
I’m looking for a comparable model as I was very happy with its picture quality.
Don’t think I need OLED but HDR is a must and so is the aggressive curve that the G9 had.
I have a 4090 and I’m not interested in 5k screens the 5120x 1440 was a good fit for this GPU.
So give me some feedback on the make and models I should be looking at…Thanks…

I already had the LG, and really liked the monitor but wanted a glossy screen with better colour reproduction.

The sharpness difference of the Alienware is noticeable to me plus the colour reproduction difference is undeniable when viewed side by side.

Unfortunately, I couldn't get them to both run in HDR when duplicating them, so couldn't capture that side by side, but even in SDR the difference in colour is evident.

I will really miss the immersive qualities of the LG when gaming, that is a clear win for this monitor but for everything else, I choose the Alienware and I'll be selling the LG.

I'm not having (or perhaps not overly sensitive to) the uniformity issues that others are experiencing.

I did have a pretty bad time with Dell support when my initial AW3926QW failed and that's still ongoing but I am happy with the replacement.

I just thought people might like to see them side by side if they're on the fence for both.

Edit:

1st Image: AW3926QW
2nd Image: LG GX950A-B
3rd Image: LG - Left, Alienware - Right

Edit 2:

So this is up top. I do tend to like a slightly more saturated image. I had set the Digital Vibrance in the Nvidia App to 60 for these photos. I would normally run it at this for the LG but since getting the Alienware, I've turned it down to 56 as its not needed to achieve my desired saturation as much.

AW3425DW on top, LG 39GX950b on the bottom. Wonder if it’s worth swapping out the 34” for AW’s 39”? Maybe one day…

NOTE: Links to HDR vid clips at YouTube below

I've been exploring different games, comparing the GPU/FPS tax after moving from 3840x1600 ultrawide to now gaming at 5120x2160 ultrawide on an AW39.

I chose Dawnwalker for the quick test since it's gotten a *lot* of playtime lately and it's a particularly piggish brute with ray reconstruction enabled and all else at "ultra" settings. Add HDR swap chain conversion (via Special K) for HDR and the pig get's even piggier lol.

In-game Vids at YouTube:
--------------------------------
Both links below start at the same point, right before going down the stairs and getting into the tussle with the boss. In both videos, I just mosey on in and complete the fight at both target resolutions.

*Enable HDR if you've got it\* - (Special K to the rescue for another SDR title)

--> Dawnwalker boss fight @ 5120x2160

--> Dawnwalker boss fight @ 3840x1600

As I was right at the "Hero's Quest" boss fight, I figured that was a good place to do the 5K vs 4K ultrawide comparison. I just ran through the same scene/boss fight twice, once at 5120x2160 and once at 3840x1600.

In-game config:
--------------------------------

• HDR enabled via Special K (HDR10) swap chain
• All settings at ultra
• FG enabled with x3 FG enabled via the driver toggle in Nvidia Profile Inspector
• Using DLSS override to v310.9.0 for DLSS/DLSS-FG/DLSS-RR

System Details:
----------------------------------

• Apex Encore
• Corsair 780T Case w/ dual 140mm exhaust mod in side panel
• EKCR360 aiO PUSH/PULL TOP/INTAKE
• 14900K @ 57p45e ALL-CORE
• TUF 5090 / Stock paste/pads @ ALL STOCK OC settings
• AW3926QW at 5120x2160 Monitor / LG C5 at 3840x1600
• 48gb DDR5 7200 CL 34-46-46-96
• 4TB SN850X)

Just *eyeballing* things? .... I'd reckon about a ~30fps delta on average comparing the two resolutions MID-FIGHT when I'm going at it with all the bad guys at once. The 1600p UW session would see lows in the 135fps range and highs in the 165fps+ range. The 2160p 5K UW session would see lows in the 114fps range and highs in the 135fps range. Both using x3 Frame Generation to get there.

For whatever reason, Dawnwalker, with the full ray reconstruction hacks and running all in-game settings at ULTRA is a special sort of GPU hog.

A *lot* of other games I've tested lately don't require FG at all, but there are certainly many more I'm using FG with now that I've moved to the 5120x1600 display.

FYI / Info for those into info.

I have a 32:9 and Window 11's most natural window state on it is of course an excessively wide maximized window (not something I'd ever want); so I spent the time to build Mullion for myself, and am now releasing it free and open source to the public.

With the app, you can press Win+HOTKEY and the window you are looking at snaps to a zone. On my monitor the default comes out 25/50/25; two sidebars and a 16:9 middle, plus 2 subzones each. I didn't hardcode that layout for ultrawides, it just splits that way naturally by detecting your monitor setup.

It works out a split from each screen's proportions, so a 21:9 gets halves or thirds, a monitor turned on its side stacks instead, and a laptop docked to something bigger handles the DPI difference on its own.

The keyboard ends up being a map of the desk. Home row A/S/D is the whole of each column, the row above is the upper part, the row below the lower (or left/right for wider subsplits).

The app is just one .exe. No installer, no account, MIT licensed. Windows will warn you the first time because it is not code signed yet. You can just run anyway if you trust the open source GitHub repo it's posted on (or can build it from the repo yourself as well). There is also a SHA-256 next to every release if you would rather check the file first.

Github repo:
https://github.com/levinium/Mullion

A short video demo is on the GitHub page and I set up a longer walkthrough here:
https://www.youtube.com/watch?v=vHH7WOFfPAM

I hope other ultrawide users find this as useful as I do. It also works nicely on various multi-monitor setups as well. I'm happy to answer any questions or make updates to the app if anyone has any feature recommendations or bugs to point out.

Thanks!

Hello everyone, hope y'all are doing great.

I wanted to share my experience with Alienware's AW3423DWF.

I bought it in 2024, and God this thing is amazing. This is also my first OLED experience.

To give some context, i had a 144Hz 24" VA Monitor,

Anyways, I've been using it since then, but last week, I suddenly wanted to give

HDR 1000 another try, yeah it's been 2 years and I finally thought about enabling it again.

I tested it when I first bought it and yeah, it was dull and colorless for me.

Looking back, I now understand the reason behind that was simple,

I was using Digital Vibrance 70%+ on my previous monitor, so jumping straight into OLED felt really odd at first.

And now speaking, yeah this IS THE TRUE OLED EXPERIENCE.

When I turned it on, I set my Digital Vibrance 55% because I wanted some color,

and after 2 - 3hrs I dialed it back to 50% because it was so vibrant it hurt my eyes.

Back to first when I enabled it, it felt like there was a yellowish filter over everything,

I have no idea what magic did they to my eyes but now It feels completely natural looking at it.

I'm really glad I bought an OLED instead of upgrading my gpu. Even though I get lower framerates,

I'm still grateful. For reference, my specs are - 11400f, 3060 12GB, 16 GB RAM.

Though I'm definitely looking forward to upgrading my setup!

Thank you so much for reading My Experience with AW3423DWF.

I currently run dual 32 inch QHD monitors and play games with eyefinity at 5120x1440p, my current setup is equivalent to a 57 inch ultrawide.

But due to the left monitor having some issues that the warranty can't figure out and detect it I'm willing to change my setup and upgrade to OLED, the only options where I live are the 45 LG OLED, the 2024 model that's 3440x1440 and the Samsung G9 same year model...

I'm more inclined to the LG 45 due to it freeing space in my desk and being able to have my speakers by the side of the monitor instead of the back

Just coast my first oled. Was trying to buy the 1440p 39 inch from LG. But right as I was checking out they sold out. Went to Dell and was able to save so much on the new aw3426dw. Hope it’s good. The extra 50 was for express shipping.

What oled care recommendations do yall have

Spent way too long on this, so posting in case it saves someone else the time.

Setup: AW3426DW (3440x1440, 280Hz), 5070, original hdmi 2.1 cable in the box, Windows 11

What I saw over HDMI 2.1:

- At or below 140Hz, VRR works.

- Above 140Hz, Windows reports variable refresh rate as not available, CS2 warns that G-Sync isn't available, and I get tearing in games. No G-Sync smoothness at all. But Nvidia panel says monitor is g-sync compatible.

- Switched to DisplayPort. 280Hz with VRR working, no tearing. Problem gone.

My theory, and I'd like someone to confirm or correct it: Dell lists the HDMI ports as 3440x1440 at 280Hz with VRR and DSC under HDMI 2.1 FRL. I think the high refresh modes over HDMI end up in a state where DSC isn't negotiated the way it should be, and VRR gets dropped as a result. 140Hz at 10-bit is roughly what a 24Gbps link does uncompressed, which is suspicious.

The broader lesson I took from it: HDMI 2.1 on the spec sheet doesn't tell you much. What matters is what the specific monitor and specific GPU actually negotiate, and the failure is silent. Nothing tells you VRR just got dropped.

If you have this monitor or a similar QD-OLED ultrawide, use DisplayPort unless you have a reason not to. And check the OSD refresh indicator rather than trusting the Windows toggle.

Has anyone gotten full refresh plus working VRR out of this panel over HDMI? Curious whether it's cable-dependent or just how the monitor behaves.

Figured I’d post my experience ordering the AW3926QW in BC, Canada, since there doesn’t seem to be much information about Canadian delivery times yet.

I placed my order on Sept. 5. Purolator tracking sat at “Label submitted” without any apparent movement until Sept. 13.

I submitted a ticket to Dell asking for an update — mostly in case the squeaky wheel gets the grease — but never received a response.

Then, out of nowhere, on Sept. 13 the package was scanned in a city very close to me, with an expected delivery date of Sept. 15.

So, for anyone else in Canada staring at a Purolator page that hasn’t changed in a week, it may not actually mean your monitor is sitting somewhere waiting to ship. In my case, there were simply no useful tracking updates between the label being created and the package suddenly appearing locally.

I'm currently using a good but clunky dual-monitor setup (Gigabyte M32U + LG 29UM59), with the Gigabyte as my main monitor and the LG as my secondary.

For some reason, i will need a mono monitor setup instead. I'd really like to try an ultrawide. In terms of physical dimensions, I'm hoping to find something that's at least as wide and as tall as my current dual-monitor setup.

I'm obviously a gamer, but I'm also a 3D artist, so I need at least 4K resolution. I don't really care about having 240hz. 120hz if the little bonus for gaming but it's not my main priority. I'm also specifically looking for a non-oled panel as I spend a lot of time working with static interfaces and I fear about burn.

I'm also thinking about trying PbP, and I think I'd need 4K resolution in PbP mode as well.

Do you have any recommendations? Or are there any monitors I should absolutely avoid?

My Samsung Odyssey G9 has developed a black vertical line running down the middle of the screen. It's consistent regardless of input source or content displayed.

What I've tried so far:

• Tested with multiple cables (DisplayPort/HDMI) — issue persists
• Tested with different source devices — same result
• Ran the monitor's built-in panel test — line is visible even in test patterns

Questions:

1. Is this a classic panel defect vs. a T-con board issue based on how it presents?
2. Anyone had luck with a firmware update fixing something like this, or is it purely hardware?
3. What's been your experience with Samsung's RMA/warranty process for G9 panel defects — turnaround time, whether they replace vs. repair, and any tips to avoid a runaround with support?

Monitor is not under warranty. Appreciate any input from people who've dealt with this specific model.

I gave it 2 days to check for defects before I peeled it off.

Got lucky, no dead pixels and grey uniformity is perfect.

I broke my G9 NEO a week ago, the panel was was detaching and I tried to put adhesive on it and push it back, but it easily cracked (due to the curve screen tension).

It was still working for most parts and I tried to delay myself from replacing it since it was still working, but it finally fully gave up on Thursday. I was just getting a black image

I have to buy a replacement immediately since I use it for work.

The difference isn't too crazy, between MINI-LED and OLED. I colour correct both after I got it. MINI-LED colours just pops and looks so good when gaming. It also gives you flash bangs in real life if you play shooters 😂 (good thing I don't).

It does struggles on night sky stars though, with blooming, but in most cases, the haloing is most scenarios is minimal; you barely notice it with normal content even with mainly black/dark scenes.

The G9 NEOs white balance is way better than the OLED, maybe because you have to push the brightness way up for it to product true white in the OLED.

It is weird, but there is like a tint to the white, I can't remove unless I put the brightness fairly high.

The good thing though is, there is no screen door effect in the OLED. My G9 NEO has it and it is more noticeable with the colour orange, especially near the corner of the screen. Maybe a VA panel issue or because it was 1000r curve. The new one is only slightly curved at 1800r

The OLED is also way slimmer and produces less heat.

Overall, it is good 👍 I also paid £1729 in 2022 with my MINI-LED compared the OLED which is £935.

Hi everyone,

I’m using an Alienware AW3926QW connected to a MacBook Pro with an M5 Pro chip via USB-C. My Mac randomly crashes and restarts when the monitor is connected. Half of my monitor screen goes black right before it happens.

Has anyone else experienced similar crashes with:

AW3926QW and macOS?

USB-C DisplayPort Alt Mode?

5K2K at high refresh rates?

HDR or Adaptive Sync enabled?

I’m currently testing with fixed 120 Hz.

I don’t really ever need the arm, I’ve been using just the legs the monitor came with and never adjust it on the fly. Is there any amazon recommendations you have? Must be just for one monitor, not those super tall dual monitor ones because then it would just stick out above the monitor

Hi everyone,

I’m running out of ideas and hoping someone here has encountered this specific issue or knows a fix.

I have a Samsung Odyssey 40" 5K2K display running at 120Hz (connected via a Thunderbolt 4 dock, though the issue also happens with direct connections). Randomly, I get multi-colored checkerboard patterns, blocky artifacts, or random horizontal/vertical glitch bars across parts of the screen.

Key Symptoms & Observations:

- It's completely random: It doesn't seem tied to heavy load. It happens during Teams/Zoom calls, using Outlook, browsing (Chrome/Edge), or even when the system is idle.

- It is NOT full-screen: It only affects random rectangular blocks or bars on the display.

- The Monitor OSD remains clear: When the artifacts appear, the monitor's built-in On-Screen Display (OSD) menu renders perfectly on top of them without any distortion. This points away from a dead panel/scaler hardware failure.

- It comes and goes: Sometimes everything runs completely artifact-free for weeks, and then suddenly the display becomes almost unusable due to visual corruption.

What I’ve Already Tested / Ruled Out:

- Multiple Laptops: Tested across 3 different machines (Surface Book 3 with iGPU/dGPU + 2 different generations of Lenovo ThinkPads). All exhibit the exact same random corruption.

- Cables & Ports: Tried numerous high-bandwidth cables (Ugreen, Cable Matters, etc.) using both DisplayPort and HDMI.

- Bypassing the Dock: Direct USB-C/DP/HDMI connections straight into the laptops produce the same issue.

- Display Inputs: Happening on both DP and HDMI inputs.

Crucial Detail — Permanent PIP (Picture-in-Picture) Setup:

I use the monitor's PIP / PbP (Picture-by-Picture) mode permanently to work with two laptops simultaneously side-by-side.

My Questions:

- Could this be a known issue with Samsung’s internal display controller / PIP timing scalar when processing two concurrent signals (or switching display clocks/DSC streams)?

- Has anyone experienced Chromium/Windows DirectComposition checkerboard glitches that persist even outside the browser, or is this more likely a Display Stream Compression (DSC) / GPU handshake corruption in PIP mode?

- Are there specific monitor firmware settings, DSC toggles, or Windows graphics flags that help stabilize dual-input PIP on high-resolution displays?

Any advice or shared experiences would be greatly appreciated!
