Ultrawide monitors
A page for Sunil — the state of the ultrawide monitor world right now, headlined by Dell’s brand-new 39″ OLED. The short version: a new generation of 5K2K (5120×2160) OLED ultrawides arrived over the past year, and Dell’s entry is the one to watch — sharper text than any OLED ultrawide before it, and hundreds of dollars cheaper than LG’s equivalents.
Snapshot as of 4 July 2026. Prices are US dollars excluding tax; “street” means commonly seen discounted prices. Several of these are announced-but-not-yet-reviewed, so treat pre-launch figures as provisional.
The headliner: Dell’s 39″ OLED — Alienware AW3926QW
Announced at Computex in June 2026 as part of Alienware’s 30th-anniversary lineup. It uses LG Display’s 4th-generation tandem WOLED panel, but with a twist Dell claims as a world first at this size: a true RGB-stripe subpixel layout, which fixes the text-fringing complaint that has dogged OLED monitors from day one. At 143 pixels per inch it’s the first OLED ultrawide with text clarity in the same league as a 27″ 4K screen — a monitor you can genuinely both work and game on.
| Spec | Detail |
|---|---|
| Panel | 39″ 21:9, LG Display 4th-gen tandem WOLED, true RGB-stripe subpixels, glossy, 1500R curve |
| Resolution | 5120×2160 (5K2K), ~143 PPI |
| Refresh | 165Hz native; dual-mode 330Hz at 2560×1080; 0.03ms GtG |
| HDR | VESA DisplayHDR True Black 500, Dolby Vision & HDR10; ~300 nits SDR, ~1,300 nits peak |
| Ports | DisplayPort 2.1 UHBR20, 2× HDMI 2.1, USB-C with 90W power delivery, built-in KVM, eARC — no Thunderbolt |
| Warranty | 3 years, including OLED burn-in |
| Price | ~$1,099 widely reported, but Dell hasn’t confirmed final US pricing |
| Availability | Late June 2026 in select Asian markets; North America & Europe in fall 2026 |
The reported ~$1,099 price undercuts LG’s own monitors on the same panel family by $700–900, while adding the RGB-stripe layout LG’s lack. Early hands-on coverage has been glowing (PCWorld called it “a glorious ultrawide monster”), but note that no full lab reviews exist yet — Western availability only starts in the fall. If you can wait for RTINGS or TFTCentral to put one on the bench, wait.
The new 5K2K OLED generation
The AW3926QW’s direct rivals — all 5120×2160, all dual-mode (165Hz native, 330Hz at 2560×1080), all built on LG Display WOLED panels.
| Model | Panel | Specs | From | Available |
|---|---|---|---|---|
| Alienware AW3926QW | 39″ WOLED · glossy | 5K2K 165Hz, RGB-stripe subpixels, 1500R, True Black 500, KVM, 90W USB-C | ~$1,099 | Fall 2026 (US) |
| LG UltraGear 39GX950B | 39″ WOLED · matte | 5K2K 165Hz, 1500R; first-announced 39″ 5K2K, same panel family but RGWB subpixels | ~$1,800 | May 2026 |
| LG UltraGear 45GX950A | 45″ WOLED · matte | 5K2K 165Hz, aggressive 800R curve, True Black 400, DP 2.1, ~125 PPI; strong reviews, price and curve are the gripes | $1,999 | 2025 |
| LG UltraGear 45GX990A | 45″ WOLED · bendable | 5K2K 165Hz, motorised flat ↔ 900R bend on demand; halo product | ~$2,500 (expected) | 2026 |
The 34″ value tier & the rest of the field
3440×1440 is now the value resolution: superb 240Hz QD-OLEDs sit at $600–800 street. Below them, the big work-first and 32:9 options.
| Model | Panel | Specs | From | Available |
|---|---|---|---|---|
| Alienware AW3425DW | 34″ QD-OLED | 3440×1440 240Hz, 1800R; the reviewers’ price–performance favourite, ~$615 street | $799 | 2025 |
| Alienware AW3426DW | 34″ QD-OLED | 3440×1440 280Hz refresh of the AW3425DW, anti-reflective coat, ~1,300-nit peak | ~$800 | Jul 2026 |
| MSI MPG 341CQPX | 34″ QD-OLED | 3440×1440 240Hz, True Black 400, USB-C with 98W power delivery; ~$650 street | $999 | 2024 |
| ASUS ROG Swift PG39WCDM | 39″ WOLED · glossy | 3440×1440 240Hz, 800R; the previous-gen 39″ king, but only ~93 PPI — superseded on sharpness by the 5K2K 39s | $999 | 2024 |
| Samsung Odyssey OLED G9 (G95SD) | 49″ QD-OLED · 32:9 | 5120×1440 240Hz, 1800R, glare-free coating, smart-TV features; still Samsung’s ultrawide flagship — the 2026 Odyssey line added no new ultrawide | $1,799 | 2024 |
| Samsung Odyssey Neo G9 (G95NC) | 57″ Mini-LED VA · 32:9 | 7680×2160 (dual-4K) 240Hz, 1000R; the non-OLED giant — brightest HDR, no burn-in risk; ~$1,600 street | $1,999 | 2023 |
| Dell UltraSharp U4025QW | 40″ IPS Black | 5K2K 120Hz, 2500R, Thunderbolt 4 hub with 140W power delivery, KVM, factory-calibrated; the productivity pick — no burn-in risk, weaker contrast; ~$1,500 street | $1,919 | 2024 |
Worth knowing before you buy
Burn-in warranties. Dell/Alienware, MSI, Samsung and (mostly) ASUS cover OLED burn-in for 3 years. LG is the weak one at 2 years in the US — worth weighing against its otherwise excellent panels. Gigabyte introduced the first 4-year burn-in warranty in 2026, a sign of growing confidence in the tandem WOLED panels’ longevity.
5K2K vs 3440×1440. The 5K2K screens are the first OLED ultrawides sharp enough for all-day text work (~143 PPI at 39″ vs ~110 PPI at 34″ and ~93 PPI at 39″ for 3440×1440). If the monitor is mostly for gaming, the 34″ QD-OLEDs at ~$650 street remain the sensible buy; if it’s your everything-screen, the 5K2K generation is the upgrade that finally justifies itself.
Connections. DisplayPort 2.1 UHBR20 (80 Gbps) is now standard on the flagships and on current Nvidia RTX 50 / AMD RDNA4 cards — it drives 5K2K at 165Hz 10-bit with little or no compression. HDMI 2.2 was announced but no shipping monitor carries it yet; everything here is HDMI 2.1.
What’s next. The AW3926QW hits North America and Europe in the fall, when the proper lab reviews land. LG’s roadmap includes a 52″ 5K2K large-format display; Samsung’s 2026 energy is going into 6K 16:9 and glasses-free 3D rather than new ultrawides. Expect RGB-stripe tandem WOLED to spread across brands, and burn-in warranties to stretch toward 4 years.
