Alienware AW3426DW review: Ultrawide and ultra-persuasive

The ultrawide gaming monitor is slowly but surely undergoing something of a shift in reputation right now, even while the wider gaming world is battered by price hikes and component shortages. Even just a couple of years ago, an ultrawide felt like the status symbol of a super-rich gamer – not really something 'normal' folks bought.

Well, times change, and display technology has been moving quickly. While ultrawides still look much like they have for years, they're now getting better and cheaper, a double whammy that you love to see. Dell's newest Alienware launch, in fact, the AW3426DW, comes in at a price that I think is really tempting given its QD-OLED status.

Price and Availability

The AW3426DW went on sale in late June here in the UK, so you can order it now directly through Dell and possibly some other enthusiast storefronts. Its RRP is £709.

US shoppers will have to pay $799.99 – with a later release date penned from 9 July 2026. There's no Australian pricing or pre-order details as yet.

Design and Specs

You might think there's a limited amount to say about the design of an ultrawide monitor. In some ways you'd be right, but the flexibility that manufacturers have on key points can be massive for the experience of using one.

The AW3426DW is a 34-inch ultrawide with an aspect ratio of 21:9, which makes it fairly typical for the market. This means that it's not the tallest monitor, so it's perhaps easier to fit onto a desk than some others I've tested, although the width is clearly the main point of contention.

The AW3426DW is built largely out of a matte-finish dark blue plastic, with a real sturdiness to its frame and stand. There's been some online criticism of that blue finish, but in person I think it's quite nice – although the footprint of the stand is fairly significant on your desk.

The arm that the screen attaches to is sturdy and offers some tilt both in terms of up-and-down and left-or-right motion. That means you can position the monitor relatively easily if you have a peculiar setup in mind. The arm also has a channel to route cables through in quite a rudimentary way.

The back of the screen is unremarkable, but there is one bit of ornamentation – a glowing RGB Alienware logo that looks nice, but really doesn't emit too much light. I could probably do without it, but it hardly impacts usability at all.

The front of the display has a status light at the bottom right that's surprisingly large, until you realise theat is doubles as the on/off button (which some monitors make much more difficult to find).

The screen's actual user interface (UI) and settings menus are accessed using a control nub right under the middle of the display, which I found really easy and responsive to use.

The panel itself is a 3440 x 1440 resolution QD-OLED Penta-Tandem RGB Stripe type, with an improved refresh rate of 280 Hz and a higher peak brightness of 1,300 nits – an increase over its '3425' predecessor.

It has HDR (high dynamic range) certification and works with Dolby Vision – which is fairly rare in this market – and can boast a VESA DisplayHDR True Black level of 500, which is also impressively rare.

Perhaps the biggest single upgrade on the monitor, though, is a new anti-reflective coating. It's hugely impactful in person, as I'll get to later in this review.

If there's a big downside to testing ultrawides, it's where multi-device functionality is concerned. The array of ports here is solid rather than outstanding – two HDMI 2.1 and a DisplayPort 1.4 are what you get, along with a 5Gbps USB Type B, plus Type A and Type C USB charging.

I usually have a 27-inch flat panel on my desk, and swap between my work MacBook Pro, my gaming PC, and my PS5 Pro according to what I'm doing and who I'm gaming with. The key part here is the PS5 Pro, which doesn't really work nicely with this monitor.

The AW3426DW does allow you to crop its picture down to a 24.5-inch version that works for devices that don't support ultrawide screens, but it's limited to 1080p and therefore loses a lot of clarity. This is far from a Dell-only issue, and really is just about what you want from your monitor – so be aware that console gaming isn't really a great fit here.

Performance

So, the AW3426DW isn't great for a PS5 Pro – what else is news, Einstein? This is a PC gaming monitor, so I used it that way for almost all of my testing. And what a lovely time I had, too.

The AW3426DW's QD-OLED panel is a really lovely one for the price. It has those inky dark blacks that you want from the technology, plus really impressive vibrancy to colour – especially with Dolby Vision-compatible content.

I used the monitor to play a dozen or so hours of Assassin's Creed: Black Flag Resynced, and the bright, bold blues of that game's oceans were really well-represented, as were its torches at night and multifaceted underwater hues.

One small miss is the lack of integrated speakers – sure, they're never great, but I sometimes find it more relaxing to game without a headset, which isn't an option with this monitor (unless you have other speakers, of course).

Another welcome factor in my enjoyment of the screen has been that anti-reflective coating; I saw it briefly at Computex in Taipei, but at home it's been revelatory – even bright and pointed lights barely make a ripple when I'm gaming. The boost this gives to immersion is truly great.

While I don't recommend it for consoles, I did also do enough PS5 Pro gaming to confirm that it's entirely acceptable on that front, too, and that swapping back and forth between modes is quick and easy to accomplish. That's worth more than nothing, at this price.

It's also worth highlighting that, unlike some other monitors of this type, the cooling for what is a big panel is all done through ventilation rather than actual fans. Some other monitors can indeed have a distracting whirr, but there's no such bugbear here.

Using the monitor for work has also been a reminder that ultrawides can be really quite practical – you get so much real estate for multitasking and windows. At 3440 x 1440, things are nice and sharp, although I have found that text can suffer from a little fringing at times, so a point of note if you're sensitive to that.

Verdict

I think Dell's Alienware brand has played a great hand here. The AW3426DW doesn't reinvent the wheel, but it crucially also doesn't charge the world – unlike some competitors.

While its QD-OLED panel isn't radically upgraded over its predecessor, instead going for modest but welcome gains, the price feels really fair for what you get.

Sure, you can get more expensive monitors that push things further in terms of resolution, size, and indeed processing power and internal capabilities – but you'll find that these upgrades come with discomfiting price spikes, too.

By avoiding those hikes, you'll be getting a monitor that feels premium in all the most important ways, even if it's secretly not as best-in-class as it looks. The Alienware AW3426DW is a great deal.

Also Consider

If you do want something that's more like the best of the best, then consider going for LG's crazy UltraGear 45GX950. It's simply massive, and therefore not quite in the same category, but it's a stunning piece of gear. It remains the high-water mark for the ultrawides I've tested.

Another alternative comes in the form of a counter-proposal. If you do want to game on both PC and console, maybe an ultrawide isn't right for you. In that case, the Sony Inzone M10S is a beautiful OLED panel – while there's now a new version, that means you might be able to find lower prices on last year's model.
