Ultrawide displays give you horizontal space with no bezel interrupting it, so you can snap multiple windows side by side without alt-tabbing. A single 34-inch ultrawide can replace two 24-inch monitors, and curved panels keep the far edges readable. Several models we used to list (the Dell U4025QW, LG 40WP95C, LG 34WQ75C and Samsung ViewFinity S9) are not currently on Amazon UK, so this edition covers verified Amazon UK alternatives with prices checked in September 2026.
What to look for
- Aspect ratio: 21:9 models (34–40 inch) suit everyday work; 32:9 (49 inch) fits three windows but needs a larger desk.
- Resolution: aim for 110+ pixels per inch; low-resolution ultrawides make text look soft.
- Curvature: tighter curves benefit larger screens; 34-inch panels work fine flat or gently curved.
- USB-C and docking: 90W or more can charge your laptop, drive the display and connect peripherals.
- Panel type: IPS for clarity, VA for contrast, OLED for visuals with burn-in considerations.
1. LG UltraFine 40U990A: best 40-inch 5K2K
A 40-inch curved 5120 × 2160 Nano IPS ultrawide at £1,169.10, rated 3.9 stars from 4 ratings. The premium option, with extra vertical height, but it needs a deep desk and has very few ratings so far.
2. Dell UltraSharp U3425WE: best 34-inch all-rounder
A 34-inch 3440 × 1440 IPS ultrawide with Thunderbolt, KVM and conferencing features, at £673.99 on Amazon UK. There are no ratings yet on this listing, but the model is our usual pick for versatility and connectivity.

3. Dell 34 Plus S3425DW: best value 34-inch
A 34-inch WQHD (3440 × 1440) 120Hz VA ultrawide at £331, rated 4.5 stars from 235 ratings. A strong entry point.
4. Philips 34E1C5600AM: best budget curved ultrawide

6. LG UltraWide 34U650A-B: best IPS 34-inch

7. Samsung Odyssey OLED G9: best super-ultrawide
A 49-inch curved DQHD OLED at £972.59, rated 3.2 stars from 28 ratings on this listing. A huge workspace and stunning contrast, but the rating, OLED burn-in considerations and desk size all need weighing.
Size comparison: 34 vs 40 vs 49 inch
- 34-inch (21:9): the sweet spot, replaces dual 24-inch monitors and fits standard desks.
- 40-inch (21:9, 5K2K): premium, with extra vertical height, and needs a deeper desk.
- 49-inch (32:9): replaces dual 27-inch screens, ideal for heavy multitasking but demanding a wide desk and head-turning.
Pros and cons
Advantages: seamless side-by-side windows, a single-cable replacement for a dual setup, excellent for spreadsheets and editing, and USB-C docking. Disadvantages: higher cost than a standard monitor, width prioritised over height, big models need space, and some apps handle ultrawide ratios poorly.
Verdict
For most users, a 34-inch ultrawide is the right size, and the Dell 34 Plus S3425DW is the value pick while the Dell U3425WE is the connectivity pick. Heavy multitaskers with a wide desk can consider a 49-inch panel. An ultrawide upgrade pays you back every working hour.
