Colour-critical reference users
People comparing digital artwork, photographs, layouts or video references who need a stated target colour space and calibration information, not just a 4K resolution.
Who is this for?
Two-laptop desk sharers
People alternating between computers at one desk, particularly when the keyboard and mouse need to follow the active computer. BenQ’s KVM setup guidance illustrates why the connections between devices matter.
Shared-desk users who need flexible positioning
People who use different seating positions or spend sustained periods at the desk. The Health and Safety Executive advises placing the screen directly in front of the user, with its top around eye level and the screen about an arm’s length away.
What matters when choosing?
Decide which colour space the artwork targets, then check how each person will position and connect the screen. For consumers sharing a desk to view reference artwork, these concerns may take priority in different ways.
| Concern | What to check | Who this matters to |
|---|---|---|
| Colour-space fit | Match the exact model’s stated sRGB or Rec.709 coverage, or its Adobe RGB or DCI-P3 coverage, to the intended artwork. Check its calibration claim and selectable colour modes. | If I compare artwork across sessions, I need a defined colour space so that 4K detail does not distract from a mismatched display setting. Around 42% of consumers may put colour-space fit first. |
| Laptop handover | Check video inputs and USB connections for both computers; if using USB-C, check the laptop’s display support and the monitor’s stated power delivery. Confirm KVM connections if peripherals must switch too. | When another person takes over the desk, I want to know whether the screen and shared keyboard and mouse can change computers without rewiring everything. Around 33% of consumers may make handover their primary concern. |
| Positioning and desk fit | Check stand adjustment, base footprint and viewing distance. If considering an arm, confirm mounting compatibility and the arm and desk limits. | A screen positioned for one person may be awkward for me, especially if the desk is shallow or the lighting causes reflections. For around 25% of consumers, adaptable positioning may come first. |
Buying pitfalls
-
Choosing by 4K resolution alone
Resolution describes image detail, not whether a display is set up for the colour space used by the reference artwork.
Identify the intended output space, then check the exact model’s colour modes and the conditions attached to any calibration or colour-accuracy claim.
-
Assuming USB-C will fully charge either laptop
Manufacturer-stated USB-C power delivery differs between models: BenQ lists 65W for the PD2705U, LG lists up to 90W for the 27UP850K-W, and ASUS lists up to 96W for the PA279CRV.
Compare the chosen monitor’s stated limit with each laptop’s charging and USB-C display requirements, and check the cable needed for the intended connection.
-
Expecting KVM switching without connecting both computers
A keyboard and mouse cannot follow the active computer unless the required video and USB paths are set up. BenQ’s KVM guidance calls for at least two video sources and notes that HDMI as the second source may require manual USB-source selection.
Plan the video and USB connections for both computers and identify where shared peripherals will plug in before choosing a KVM-equipped monitor.
-
Leaving the screen in one person’s position
A fixed setup may place the screen at an unsuitable height or distance for the next user. The Health and Safety Executive advises keeping the screen directly in front of the user, around an arm’s length away, with its top at eye level.
Choose adjustment that fits the desk and reset the screen position when users change.
Relevant brands and models
These named models illustrate different colour and shared-desk features; a brand name alone does not establish the specifications of another model in its range.
BenQ
The 27-inch 4K IPS PD2705U is positioned for sRGB and Rec.709 work with USB-C and shared-device features.
- BenQ states 99% sRGB and 99% Rec.709 coverage, average Delta E ≤3, a factory calibration report, KVM and PIP/PBP for the PD2705U.
- Its stated USB-C power delivery is 65W; compare that figure with the laptop’s charging requirement. BenQ’s KVM guidance also makes the connection setup important.
ASUS ProArt
The PA279CV is an sRGB and Rec.709 option; the PA279CRV adds stated Adobe RGB and DCI-P3 coverage for work targeting those spaces.
- ASUS states 100% sRGB and Rec.709 coverage for the PA279CV, and 99% Adobe RGB and DCI-P3 coverage for the PA279CRV. It lists Calman verification and Delta E <2 for both.
- Wider stated gamut is not, by itself, a reason to choose the PA279CRV for sRGB artwork. Match the model and selected colour mode to the workflow.
Dell UltraSharp
Dell’s 27-inch 4K UltraSharp models offer hub-style connectivity and stand-adjustment options worth checking for a shared desk.
- Dell lists the U2725QE as a 27-inch 4K IPS Black model with a stated 3000:1 contrast ratio and 120Hz refresh rate.
- Dell’s colour-coverage, calibration and 90W USB-C figures for the earlier U2723QE should not be transferred to the U2725QE. Check the specification of the exact model being considered.
LG UltraFine
The 27UP850K-W is a 27-inch 4K IPS option with stated DCI-P3 coverage, USB-C connectivity and stand adjustment.
- LG states 95% DCI-P3 coverage and USB-C power delivery of up to 90W for the 27UP850K-W.
- For colour-critical reference work, confirm the appropriate colour mode and calibration process; LG says calibration software is not included in the package.

Common questions
What should two people agree on before judging artwork on the same monitor?
Agree on the intended output colour space and use the same monitor colour mode and application colour-management settings. For sRGB or Rec.709 reference work, check the exact monitor’s stated coverage and calibration claim; choose Adobe RGB or DCI-P3 settings when the workflow targets those spaces.
Do we need a KVM switch at a shared desk?
A KVM switch is useful when the keyboard and mouse must move with the active computer; switching only the picture may require no more than suitable video inputs. BenQ’s setup guidance calls for at least two video sources and says an HDMI second source may need manual USB-source selection.
How should different users position a shared monitor?
Adjust the monitor for each user rather than leaving it in one fixed position. The Health and Safety Executive advises placing the screen directly in front, about an arm’s length away, with its top around eye level; check that the stand or a compatible arm allows that setup at the desk.
What should I do with a monitor I am replacing?
Consider reuse or an appropriate electrical-equipment recycling route rather than putting it in general waste. GOV.UK’s guidance on waste electrical and electronic equipment explains that the framework aims to reduce electrical waste sent to landfill or incineration.
