Detail-first portfolio designers
If you keep browser breakpoints, design-tool panels and high-resolution images open together, the 5K2K canvas specified for the Dell U4025QW and LG 40U990A-W may matter more to you than a smaller desk footprint.
Who is this for?
Colour-conscious visual designers
If portfolio imagery and interface colours are your priority, look for colour-space and calibration documentation that fits your workflow. BenQ UK publishes these details for the 34-inch PD3420Q, although its 3440 × 1440 canvas is smaller than the 5K2K options.
Laptop-based home-office multitaskers
If you want one display connection at a fixed desk, compare your laptop’s video and charging requirements with the exact monitor. Dell UK and BenQ UK specify different power-delivery limits across the models discussed here.
What matters when choosing?
40-inch 5K2K
Choose when: A detailed canvas for a browser layout beside design tools is your main priority.
Trade-off: Check desk depth and computer output carefully. Dell UK specifies the 39.7-inch U4025QW at 5120 × 2160; LG UK specifies the 40-inch 40U990A-W at the same resolution.
38-inch WQHD+
Choose when: You want a wider physical workspace than a 34-inch screen and a USB-C hub at your home desk.
Trade-off: Dell UK specifies the 37.5-inch U3824DW at 3840 × 1600, so it has fewer pixels than the 5K2K models.
34-inch design-focused WQHD
Choose when: Published colour modes and calibration information matter more to you than maximum canvas size.
Trade-off: BenQ UK specifies the PD3420Q at 3440 × 1440, leaving less room for dense multi-window work than the larger options.
| Concern | What to check | Who this matters to |
|---|---|---|
| Detailed working canvas | Compare native resolution and screen size, then check your computer’s supported display output and available desk depth. | If I need a browser preview beside design panels and image assets, visible detail is my first priority. Around 42% of consumers put the working canvas first. |
| Colour assurance | Check the exact model’s stated sRGB or P3 coverage, colour modes and calibration documentation against your workflow. | When portfolio images and interface colours are central to my work, I want documented colour settings rather than judging by screen size alone. Colour assurance comes first for around 33% of consumers. |
| Laptop connection and desk fit | Match USB-C or Thunderbolt video and charging requirements to your laptop; measure the space needed for the stand or a compatible arm. | I need the screen to connect to my laptop and sit comfortably on my home desk without making either task an afterthought. For around 25% of consumers, that setup is the primary concern. |
Buying pitfalls
-
Choosing screen size before measuring the desk
A larger ultrawide is not automatically comfortable at a shallow desk. The Health and Safety Executive advises positioning a screen about an arm’s length away, with its top near eye level.
Measure usable desk width and depth, then check the stand’s dimensions and adjustment range. If you plan to use an arm, confirm mounting compatibility for the exact model.
Achieving that position may require a monitor arm or a different workstation arrangement.
-
Assuming every USB-C connection does the same job
Video capability and power delivery differ by monitor and laptop. Dell UK specifies up to 140 W for the U4025QW and 90 W for the U3824DW; BenQ UK specifies up to 65 W for the PD3420Q. Those limits do not establish what a particular laptop will support.
Compare the laptop manufacturer’s external-display and charging requirements with the exact monitor and cable you intend to use.
Depending on that combination, you may still need a compatible cable, adapter or separate laptop charger.
-
Treating a colour specification as a complete workflow guarantee
A manufacturer’s gamut or Delta E figure describes a stated monitor specification, not how every browser, exported file or client screen will display a portfolio.
Choose colour-space settings that match your deliverables, check the exact model’s calibration documentation and use colour-managed applications where your workflow calls for them.
-
Assuming a similarly named listing is the same monitor
Panel type, resolution, connections and stand features can change between models in one range. Availability can change too.
Before ordering, check the current product-detail page for the exact model, its specifications, warranty information and availability.
Brands to consider
These manufacturer ranges illustrate different choices for portfolio work; the specifications apply to the named models, not every monitor from each brand.
Dell
Dell UK’s UltraSharp range includes desk-oriented 38- and 40-inch ultrawide hub monitors.
- Dell UK specifies a 39.7-inch, 5120 × 2160 IPS Black panel and up to 140 W power delivery for the U4025QW.
- The 37.5-inch U3824DW has a smaller 3840 × 1600 canvas and 90 W power delivery; compare the two against the space and connection you need.
BenQ
The DesignVue PD3420Q is a 34-inch option for a workflow that prioritises published colour information.
- BenQ UK specifies 100% sRGB, 98% P3, average Delta E ≤3 and a factory calibration report for the PD3420Q.
- Its 3440 × 1440 resolution provides fewer pixels than the 38-inch WQHD+ and 40-inch 5K2K models discussed here.
LG
LG UK lists both 34-inch WQHD ultrawides and a 40-inch 5K2K UltraFine model.
- LG UK specifies the 40U990A-W with a 5120 × 2160 Nano IPS Black display and Thunderbolt 5.
- Check computer compatibility, desk fit and the colour documentation needed for your own workflow rather than relying on the display’s creator-oriented positioning.

Frequently asked questions
Should I choose a 34-inch or 40-inch ultrawide for a portfolio homepage?
Choose by the space and documentation your work needs, rather than screen size alone. BenQ UK specifies a 3440 × 1440 panel and published colour figures for the 34-inch PD3420Q; Dell UK and LG UK specify 5120 × 2160 for the U4025QW and 40U990A-W respectively. A larger canvas is useful only if your computer and desk can accommodate it comfortably.
Can one USB-C cable carry video and charge my laptop?
It can if your laptop and the exact monitor support the required video connection and the monitor’s power delivery suits the laptop. Dell UK specifies up to 140 W for the U4025QW and 90 W for the U3824DW, while BenQ UK specifies up to 65 W for the PD3420Q. Check the laptop manufacturer’s display and charging requirements before relying on one cable.
How should I position an ultrawide at a home desk?
Aim for a position you can use without twisting or sitting too close. The Health and Safety Executive advises placing the top of the screen near eye level and the screen about an arm’s length away. Check desk depth and the monitor’s stand adjustment before choosing a larger model.
Do display-screen-equipment rules apply to home workers?
They can apply to workers using display screen equipment daily for continuous periods of an hour or more, including when they work at home, according to the Health and Safety Executive. The duties described in its guidance are employer duties; buying a monitor for yourself does not turn them into a personal product-registration requirement.
What should I do with an old monitor?
Use an appropriate electrical-equipment collection or retailer take-back route rather than putting a monitor in ordinary household waste. GOV.UK identifies the Waste Electrical and Electronic Equipment Regulations 2013, as amended, as the legislation underpinning UK recovery, reuse and recycling measures; check which collection options are available to you.
