For two people reviewing colour edits on one screen, prioritise a suitable colour mode and a workable calibration process before screen size or refresh rate. A 40-inch 5K2K display offers more pixel area than a 34-inch 3440 × 1440 model, while a smaller creator display may make more sense when colour-mode switching or a more contained desk setup matters most. Check both viewing positions and whether the computer can drive the chosen display.
Who is this for?
Two-person colour reviewers
If you discuss a live edit beside a reference image, colour modes and a repeatable calibration process matter more to the decision than gaming-focused specifications. Check the actual seating positions before relying on a panel description to judge how the image will look to both people.
Creators using one editing canvas
If you need an edit, reference material and tool panels visible together, a 5K2K ultrawide provides more pixel area than a 3440 × 1440 model. Make sure your applications and computer can use that space as intended.
Laptop-led shared-desk users
If laptops take turns at the desk, check video support, charging requirements and how peripherals switch between computers. A USB-C connector alone does not settle those questions.
What matters when choosing?
Start with the colour space used for the finished work, then establish how you will check the screen against a common target. Only then choose the canvas and connections that fit the desk.

What to check |
Who this matters to |
| Colour-reference workflow |
Match sRGB, Rec.709 or P3 modes to the work; check the calibration options and any equipment required. |
When judging an edit against a reference, I need both images assessed against an intended colour target, not just a gamut claim. Roughly 42% of consumers would put that colour-reference need first. |
| Shared canvas and viewing |
Compare native resolution and physical dimensions; measure desk space and consider both seating positions. |
If we need the edit, reference and tools open together, usable screen area and where we can sit become decisive. That shared-canvas need comes first for around 33% of consumers. |
| Laptop and desk integration |
Confirm the host's video mode and charging needs, plus any required KVM or peripheral-switching functions. |
When more than one laptop uses the desk, I want to know how each computer connects and accesses shared devices. About 25% of consumers would make desk integration their primary concern. |
Common buying mistakes
-
Treating wide-gamut coverage as proof of accurate colour
A gamut figure does not set the white point, brightness, gamma or profile used for a particular editing workflow. EIZO explains that calibration adjusts a monitor towards a defined target using a dedicated sensor.
Choose the mode that matches the work, set a shared target and check which calibration methods the exact monitor supports.
The chosen calibration process may require a compatible colourimeter.
-
Choosing a high-resolution screen before checking the laptop
The intended resolution, refresh rate and docking functions depend on the computer and connection, not just the monitor's specifications.
Check the laptop's external-display modes, USB-C DisplayPort or Thunderbolt support and charging requirements against the exact monitor.
-
Assuming one ultrawide will suit every two-screen workflow
A continuous canvas removes the central bezel, but editing applications may arrange windows differently on an ultrawide. LG also notes that a higher-resolution ultrawide can demand more graphics capability.
Check how your editing and proofing applications handle windows, scaling and colour management before replacing two displays.
Relevant brands to consider
Dell
The UltraSharp U4025QW is a 39.7-inch curved 5K2K IPS Black option for a shared workstation with docking and networking.
- Dell specifies 99% DCI-P3, 100% sRGB and BT.709, average Delta E below 2, up to 140 W power delivery and 2.5GbE Ethernet for the U4025QW.
- Its large curved screen needs sufficient desk space; confirm the host supports the intended resolution, refresh rate and connections. Dell's colour figures are specifications, not measurements of the unit you receive.
BenQ
The 34-inch PD3420Q centres on colour modes and switching between computers.
- BenQ specifies 100% sRGB and Rec.709, 98% P3, a factory calibration report, KVM and Picture-by-Picture/Picture-in-Picture functions for this model.
- Its native resolution is 3440 × 1440 rather than 5K2K, and BenQ specifies 65 W USB-C power delivery; check that against your workspace and laptop requirements.
LG
LG's 40WP95CP-W and 40U990A-W are distinct 40-inch-class 5K2K routes for a wide editing desk.
- LG specifies a 39.7-inch Nano IPS panel, typical 98% DCI-P3 coverage, Thunderbolt 4 and up to 96 W power delivery for the 40WP95CP-W. The 40U990A-W is a separate 5K2K Nano IPS Black model with Thunderbolt 5.
- Hardware calibration on the 40WP95CP-W requires a separately sold calibrator. Check colour specifications for the 40U990A-W separately rather than assuming they match.
ASUS
The 34.1-inch ProArt PA34VCNV combines sRGB and Rec.709 specifications with laptop docking.
- ASUS specifies 100% sRGB and Rec.709, claimed Delta E below 2, Calman verification, 96 W USB-C power delivery and RJ45 Ethernet for this model.
- If your work requires documented P3 coverage, confirm it for the exact model before choosing it for that purpose.
Joybuy product choices
This 49-inch, 32:9 option is for a particularly wide shared canvas. Check its colour-management arrangements separately before using it to judge colour-critical edits.
No image available
Acer X Predator X49X 49-inch QD-OLED ultrawide
The 49-inch, 32:9 format is worth considering if you need several windows visible on one screen and have room for its curved panel.
QD-OLED panel; 1800R curve; stated 240 Hz refresh rate. Before colour-critical comparison, confirm its colour modes and calibration options. Check desk fit, both viewing positions and the computer's supported display modes.

Frequently asked questions
Do I need a calibrator to compare colour edits?
For colour-critical comparison, use a defined target and a compatible measurement device rather than relying solely on factory settings. EIZO explains that calibration uses a dedicated sensor to adjust a monitor towards a target; LG says the hardware calibrator for its 40WP95CP-W is sold separately. Check the calibration method and device compatibility for the exact screen you choose.
Will one USB-C cable provide video, charging and hub access?
Not necessarily: both the laptop and monitor must support the required video connection, and the monitor's power delivery must meet the laptop's needs. Check the exact ports, supported display mode and charging specification on both devices.
Does a monitor sold in Great Britain need UKCA rather than CE marking?
No: GOV.UK guidance for electrical equipment lists UKCA or CE marking routes for Great Britain, and its guidance updated on 21 August 2026 says CE marking continues to be recognised alongside UKCA. Check the applicable requirements separately if the monitor is being supplied to Northern Ireland.
What should I do with an old monitor?
Use an electrical-waste collection route or ask the retailer about taking back an old monitor of the same type when you buy a replacement. GOV.UK describes same-type retailer take-back obligations; confirm the retailer's arrangements if you need collection rather than an in-store handover.
