The Best Ultrawide Monitors: 4 Compared (and One to Skip)
Four current 34-inch 21:9 ultrawides from LG, Dell, ASUS, and Samsung compared on panel quality, speed, connectivity, and everyday comfort.
The verdict in 30 seconds
What mattered most
- Panel type
- Max refresh rate
- HDR & contrast
- Connectivity & hub
- Productivity comfort
- Biggest drawback
A 34-inch 21:9 ultrawide is the sweet spot between a single cramped 16:9 screen and an unwieldy dual-monitor setup: wide enough for two full windows or an immersive game, small enough to fit a normal desk. We compared four current models from LG, Dell, ASUS, and Samsung — two OLEDs built for speed, one Thunderbolt-hub workhorse, and one smart-TV hybrid. Two earn a clear buy, one is a superb but pricey maybe, and one is easy to pass on in 2026.
The 240Hz OLED ultrawide that delivers flagship-class gaming for noticeably less than its rivals.
Best for: Gamers who want top-tier OLED speed and immersion without paying flagship money
- 240Hz OLED panel with near-instant response — independent testing found essentially zero ghosting
- Deep 800R curve and true-black contrast make games and movies genuinely immersive
- Anti-glare finish handles normal room lighting well
- Frequently the least expensive 240Hz OLED ultrawide in its class
- No USB-C input or KVM, so it is a weak hub for laptop users
- Full-screen brightness drops noticeably in bright rooms, a common OLED trait owners mention
A Thunderbolt-hub workhorse that turns one cable into an entire desk setup.
Best for: Remote workers and docked-laptop users who want one cable, all-day text comfort, and no burn-in worries
- IPS Black panel roughly doubles typical IPS contrast while keeping crisp, fatigue-free text
- Thunderbolt 4 with laptop charging, 2.5GbE Ethernet, a built-in KVM, and a deep port selection
- 120Hz refresh keeps scrolling and casual gaming smooth with zero burn-in risk for static work
- Reviewers consistently praise its color accuracy out of the box
- HDR is basic — no real highlight punch compared with the OLEDs here
- 120Hz and slower pixel response can't match OLED motion clarity for serious gaming
Arguably the most polished 34-inch OLED you can buy — if you're willing to pay flagship money for it.
Best for: Enthusiasts who want the best 34-inch OLED available and don't mind paying a premium for refinement
- Same 240Hz OLED class as the LG but with brighter HDR highlights — independent testing measured exceptional peak brightness in small highlights
- Custom heatsink design aimed at long-term panel longevity
- USB-C input with laptop power delivery plus HDMI 2.1, a more flexible port mix than the LG
- Reviewers repeatedly call it the best-performing 34-inch ultrawide OLED they've tested
- Costs meaningfully more than the LG for a similar core panel and refresh rate
- Glossy screen looks stunning in dim rooms but picks up reflections in bright ones
A gorgeous QD-OLED held back by a slower refresh rate and smart-TV baggage its rivals don't carry.
Best for: Only someone who specifically wants streaming apps built into the monitor itself
- QD-OLED panel with vivid color and a genuinely effective glare-free matte coating
- Strikingly slim metal design that looks premium on any desk
- 175Hz refresh trails the 240Hz LG and ASUS at a similar price
- Built-in smart-TV platform adds a remote, a slower interface, and ads owners frequently complain about
- Fiddly micro-sized video connectors instead of full-size ports

How we judged the field
We don’t run a lab. Instead, we synthesized what independent testing consistently measures — response times, brightness, contrast, color accuracy, input lag — with what owners actually report after months at the desk: text clarity, reflections, software quirks, and reliability. For a 34-inch 21:9 ultrawide that has to earn its desk space for both productivity and gaming, we weighted four things: motion performance, everyday text and viewing comfort, connectivity (especially for docked laptops), and whether the price asked is justified by what you get in 2026.
LG UltraGear 34GS95QE-B — buy
LG’s 240Hz OLED ultrawide is the value anchor of the premium 34-inch class. Independent testing found essentially instantaneous pixel response — motion stays sharp at speeds no LCD can match — along with the perfect blacks and vivid HDR that make an 800R curved OLED so immersive. The matte anti-glare finish is a quiet advantage over glossier rivals in ordinary rooms. What seals the verdict is positioning: this monitor routinely undercuts every other 240Hz OLED ultrawide while giving up very little. The honest caveats are a spartan hub — no USB-C input, no KVM — and the usual OLED behavior of dimming full-screen white content, which owners notice most in bright rooms and spreadsheet-heavy work. If gaming is a meaningful part of your screen time, this is the smartest buy of the four.
Dell UltraSharp U3425WE — buy
The Dell is the opposite bet: it trades OLED theatrics for the best working experience here. Its IPS Black panel delivers roughly twice the contrast of conventional IPS while keeping the crisp subpixel text rendering OLEDs still can’t quite match, and reviewers report excellent out-of-box color accuracy. The real story is the hub: Thunderbolt 4 with enough power to charge a laptop, 2.5-gigabit Ethernet, a built-in KVM for switching between two computers, and a deep roster of USB ports. One cable in, entire desk connected. The 120Hz refresh — generous by productivity-monitor standards — keeps scrolling fluid and handles casual gaming fine. It won’t thrill an HDR enthusiast or a competitive gamer, but for eight-hour workdays with zero burn-in anxiety, it’s the clear pick.
ASUS ROG Swift OLED PG34WCDM — it depends
By most accounts this is the most accomplished 34-inch OLED ultrawide on sale: the same 240Hz class as the LG, but with brighter HDR highlights, a custom heatsink designed to protect the panel long-term, and a more flexible port mix including USB-C with laptop charging. Independent testing praises its color accuracy and calls its gaming performance essentially flawless; several reviewers name it their favorite in the category. So why not a straight buy? Price. It sits a full tier above the LG for a similar core experience, and its glossy screen — spectacular in a dim room — picks up reflections in bright ones. If budget is no object, or the USB-C input and extra HDR punch matter to you, it will not disappoint. For everyone else, the LG delivers most of this monitor for meaningfully less.
Samsung Odyssey OLED G8 (G85SD) — skip
Samsung’s QD-OLED panel is genuinely lovely — vivid color, true blacks, and an unusually effective glare-free matte coating on a strikingly slim metal chassis. The problem is everything around it. At 175Hz it refreshes noticeably slower than the 240Hz LG and ASUS that sit in the same price bracket. Its settings and smart features lean on a bundled remote and a smart-TV operating system that owners describe as sluggish and increasingly ad-cluttered — friction its rivals simply don’t have. Video inputs use fiddly micro-sized connectors rather than full-size ports. None of these flaws is fatal alone, but together they mean you pay premium money for the slowest and least convenient monitor of the group. Unless built-in streaming apps are the feature you’re buying, choose the LG or the ASUS instead.
LG UltraGear 34GS95QE-B vs Dell UltraSharp U3425WE: which should you buy?
This comes down to how your hours split. The LG is the performance choice: 240Hz OLED motion, perfect blacks, and real HDR make it dramatically better for games and films, and it’s entirely capable for everyday work too. The Dell is the workflow choice: sharper long-session text comfort, no burn-in risk with static toolbars, and a Thunderbolt hub that replaces a docking station — one cable charges your laptop, drives the screen, and connects Ethernet, keyboard, and mouse. If you game most evenings, buy the LG and accept the barer connectivity. If your monitor is primarily an office tool that occasionally plays a game, the Dell will serve you better every single day. Households doing half and half should lean LG — its work compromises are smaller than the Dell’s gaming compromises.
What to look for
- Panel type sets the personality. OLED wins motion, contrast, and HDR; a quality LCD like IPS Black wins static-text comfort and eliminates burn-in concern.
- Refresh rate should match your use. 120Hz is plenty for work; fast-paced gamers benefit from 240Hz, especially on OLED.
- Check the hub, not just the panel. USB-C or Thunderbolt with laptop charging, KVM switching, and Ethernet can replace a dock — or be entirely absent.
- Matte vs glossy matters in bright rooms. Glossy looks richer in dim lighting; matte is more forgiving near windows.
- Mind the curve. Around 800R is immersive for gaming; gentler curves feel more natural for straight-line design work.
- Confirm warranty terms on OLED models, ideally with explicit burn-in coverage.
Our final take
The 34-inch ultrawide category in 2026 has matured into two clear lanes, and our two buys own one lane each. The LG UltraGear 34GS95QE-B is the best all-round pick — flagship OLED gaming performance at the most sensible price in its class. The Dell UltraSharp U3425WE is the productivity equal: a superb panel wrapped around the most useful connectivity of any monitor here. The ASUS PG34WCDM is the better-than-it-needs-to-be option for buyers who want the finest 34-inch OLED regardless of cost, and the Samsung Odyssey OLED G8 is the one we’d pass on — a beautiful panel undermined by slower speed and software friction its price can’t justify. Pick your lane, and you’ll be happy for years.
Questions, answered
Is a 34-inch 21:9 ultrawide better than two separate monitors?
For most people, yes. You get roughly the workspace of two smaller screens with no bezel down the middle, one cable, and simpler window management. Dual monitors still win if you need to physically angle a second screen toward a colleague or camera, or if you want one screen in portrait orientation.
Should I worry about OLED burn-in if I use an ultrawide for work?
It's a real but manageable consideration. Modern OLED ultrawides ship with pixel-refresh routines, screen-move features, and multi-year warranties that often cover burn-in. Owners who mix usage report few problems, but if your screen shows the same static toolbars eight hours a day, every day, an LCD like the Dell U3425WE removes the concern entirely.
Do I need a powerful graphics card for 3440x1440 gaming?
It helps. Ultrawide 1440p pushes roughly a third more pixels than standard 1440p, so hitting high frame rates in demanding games takes a mid-range to high-end modern GPU. Esports and older titles will run fast on much more modest hardware, and upscaling technologies close the gap in heavier games.
Is 120Hz enough, or should I insist on 240Hz?
For office work, browsing, and casual gaming, 120Hz looks and feels smooth — the Dell's 120Hz is a big step up from a standard 60Hz office monitor. Competitive and fast-paced gamers will notice the extra motion clarity of the 240Hz OLEDs from LG and ASUS, especially combined with OLED's near-instant pixel response.
Why skip the Samsung when its panel is so good?
The panel itself is excellent — that's not the issue. At a similar price to 240Hz rivals it refreshes at only 175Hz, its settings and inputs lean on a remote and a smart-TV interface that owners describe as slow and ad-cluttered, and its micro-sized connectors are less convenient than full-size ports. Unless you specifically want built-in streaming apps, the LG or ASUS is the stronger buy.
