Choose an ultrawide with stated colour coverage and modes that match the work you deliver: sRGB or Rec.709 for those workflows, or appropriate P3 coverage for P3-oriented work. A 34-inch 3440 × 1440 screen offers room for side-by-side editing, while a roughly 40-inch 5120 × 2160 screen offers more pixels; neither removes the need for a maintained display profile, colour-managed software and suitable viewing conditions.
If edits must be compared before delivery, the output colour space, calibration state and colour-managed application matter more to this decision than refresh rate. Adobe identifies calibration state, ambient light and differences between applications as factors that can change how colour appears.
If you mainly deliver sRGB or Rec.709 work, an ultrawide can keep an edit and its reference material or application panels visible together. Check the stated modes and coverage for the output you use.
If the monitor also needs to connect peripherals and charge a laptop, match its upstream port and power-delivery rating to the laptop. A USB-C connector alone does not establish what the whole setup can do.
Decide which colour space you need to judge, then compare the viewing workspace and connections without treating a published gamut or accuracy figure as a substitute for your own colour-management workflow.
| Concern | What to check | Who this matters to |
|---|---|---|
| Colour-management reliability | Check the relevant colour modes and whether you can calibrate and profile the display for your editing software. | When I compare an edit before delivery, I need the display and application to handle colour consistently; around 40% of consumers put this need first. |
| Delivery colour space | Match the exact model’s stated coverage and modes to sRGB, Rec.709 or the P3 workflow you use. | If my work has a defined output space, I want to judge it in the corresponding mode rather than choose a screen labelled only as wide-gamut; roughly 30% of consumers prioritise that match. |
| Side-by-side workspace | Compare resolution and physical fit: 3440 × 1440 at about 34 inches and 5120 × 2160 at about 40 inches are different layouts. Check the computer’s supported output. | I need enough room to view edits alongside reference material without giving up a workable desk layout; about 20% of consumers make workspace their primary concern. |
| Laptop integration | Check the specific upstream port’s video support and charging rating against the laptop, plus any hub or Ethernet connections you need. | When I work from a laptop, I want the display connection to handle my desk setup as well as the image; around 10% of consumers put that integration first. |
Coverage describes a different characteristic from how accurately a display shows a colour. Adobe also identifies calibration state, ambient lighting and application colour handling as reasons displays can differ.
Choose coverage for your output space, then plan how you will calibrate and maintain the display profile when dependable comparisons matter.
A colour-critical workflow may also require a colourimeter and time for periodic calibration.
A 34-inch 3440 × 1440 screen and a roughly 40-inch 5120 × 2160 screen differ in pixel workspace as well as physical size.
Check the exact resolution, stand adjustment and desk fit, then confirm that your computer and chosen connection support the intended display setting.
Dell, ASUS and BenQ publish different charging ratings and connection arrangements for the models discussed below. The connector shape alone cannot confirm laptop charging or the intended video output.
Match the laptop’s requirements to the exact monitor port, and check any Ethernet, hub or KVM functions you intend to use.
LG lists the 40WP95C-W as discontinued and the similarly named 40WP95CP-W separately. A short or incomplete model name can therefore lead you to check the wrong specification page.
Match the complete model number on the product page to the specifications, current status and warranty terms before ordering.
The UltraSharp U4025QW is a reference point for a large, dock-oriented colour-editing workspace.
The PA34VCNV is relevant to a 34-inch editing layout centred on sRGB and Rec.709 output.
The PD3420Q combines a 34-inch ultrawide layout with published coverage for several editing colour spaces.
The 40WP95CP-W is relevant when a roughly 40-inch 5K2K workspace and hardware-calibration support are priorities.
These 49-inch, 32:9 screens offer a wide layout for keeping editing windows together. Assess their colour modes, calibration options and desk fit for your own work; they are not the 34-inch 3440 × 1440 or roughly 40-inch 5120 × 2160 configurations discussed above.

Consider its 32:9 layout if you want editing windows and reference material on one wide screen. The listed configuration includes an 1800R curve, Double Quad HD resolution, 240Hz refresh rate and USB-C; confirm the colour modes, accuracy and calibration options needed for your output before relying on it for critical comparisons.
Image unavailable
Consider its 32:9 layout if your main need is room for an edit and other windows side by side. The listed configuration has a 1500R curve, 165Hz refresh rate, HDMI 2.1 and DisplayPort 1.4 connections, and height adjustment. Check which colour modes, accuracy and calibration options suit your delivery work, and confirm that the desk or mount can support the screen.
For colour-critical comparisons, plan for calibration and profiling even when a manufacturer publishes a low Delta E figure. Adobe identifies monitor age, calibration state, ambient light and application colour handling as sources of variation; a model’s published figure cannot establish how your display will behave over time in your room.
Choose coverage and a mode that match the output you are judging: sRGB for sRGB work, Rec.709 for that SDR video workflow, or appropriate P3 coverage for P3-oriented work. Use a colour-managed application and maintained display profile rather than relying on a wide-gamut label alone.
It can if the laptop and the monitor’s specific port support the intended video output and sufficient power delivery. For context, Dell lists power delivery up to 140W for the U4025QW, ASUS lists 96W for the PA34VCNV and BenQ lists 65W for the PD3420Q; check your laptop and the exact connection before choosing.
GOV.UK guidance recognises CE marking alongside UKCA marking in Great Britain where the relevant product requirements are met; a marking alone does not establish that an individual monitor meets them. If the monitor is being supplied to Northern Ireland, check the documentation for that market separately.
